Normally, I don't post about supplements or drugs. However, an email just appeared in my in-box that made me think an exception may be in order.
According to an email from the American Diabetes Association;
"The government's preliminary evaluation of the diabetes pill Avandia confirms the heart risks reported in an earlier study and suggests that as many as 60- 100,000 heart attacks might be linked to its use over the last eight years, a leading member of Congress said Thursday."
Now I know that word-bites such as this tend to blow the results of any study way out of proportion, so I will reserve an hard comments until I get all the facts, but the reason I chose to post about this topic is as follows:
I find it very frustrating that governments and health professionals are so quick to turn to drug treatment for diabetes, and are so opposed to any dramatic nutritional interventions.
Adam Campbell of Men's Health Magazine has been fighting this battle for a while now (See his blog HERE), and has stated time and time again that the "primary treatment for diabetes should be diet (and, of course, exercise)" and I agree.
This is more of a rant than anything else, but I will end with saying that diet and exercise are and always will be your best tools in the battle to stay healthy.

More Trouble for Diet Pop and Sodium Benzoate
Looks like Benzene and Sodium Benzoate are back in the news again.
If you remember, I wrote about diet pops, sodium benzoate and health risks HERE.
According to a recent release on foodqualitynews.com, it appears that recent research has suggested that "benzoate contributes to faster ageing and degenerative diseases such as Parkinson's".
Members of the soft drink industry have shot back saying that sodium benzoate is "approved for use by the Food Standards Agency and we follow the guidance of the regulatory authorities."
I don't know about you, but for me this recent development adds to the volume of questions that surround this ingredient.
My advice, treat pop the way it should be treated...like a dessert.

The Difference Between a Diet Book and a Nutrition Book
In my quest to read as many diet and nutrition books as possible, I have stumbled across the difference between a "Diet Book" and a "Nutrition Book".
A Nutrition Book is roughly 300 pages of information on food, food politics and some biochemistry.
A Diet Book is roughly 300 pages of information of food, food politics, some biochemistry and recipes.
The difference is that in a nutrition book, all 300 pages are full of information. In a diet book, only the first 50 or so pages are information, the rest is filler in the form of recipes, food combining charts and calorie counters.
Most of today's diet books are one days-worth of reading, tops.

Can Fish Oils Make You Thin?
If you've read the news in the last couple of days then you've probably read all the headlines about a new study that shows that the combination fish oils and exercise can help you lose fat.
To quickly summarize the study, researchers randomly assigned 75 overweight men and women to one of four groups:
- Group One took 6 grams of fish oil per day,
- Group Two took 6 grams of fish oil per day and exercised 3 days per week;
- Group Three took 6 grams of sunflower oil (the placebo), and
- Group Four took 6 grams of sunflower oil and exercised 3 days per week.
The subjects in this group lost a little over 3 pounds of fat in 12 weeks. Definitely not extraordinary, but significant nonetheless.
So people who exercised lost some fat. In my opinion this was expected. What was not expected was that the sunflower plus exercise group did not lose any fat.
Now, these people also added exercise to their lifestyle, so you would expect them to also lose fat. So either the combination of fish oil and exercise somehow 'created' this extra fat loss, or, pardon the pun, something is fishy with this study.
On closer inspection of the data I noticed something that may account for these results.
While the fish oil plus exercise group reported that their daily calorie intake pretty much remained the same for the 12 weeks of the study, the sunflower plus exercise group saw their daily caloric intake increase by 327 Kcals per day by week 6 of the trial, and stay elevated by 230 Kcals at week 12.
While the researchers make no mention of this as being significant, it may help explain the lack of fat loss in the sunflower plus exercise group.
At the end of the day, caloric restriction and exercise are the only way to lose fat. The better your exercise program and the better your diet, the more fat you will lose. Plain and simple.
However, don't rule out fish oils. Most fish oil research finds that they can benefit blood lipids and your cholesterol profile.
Bottom line, Fish oils are good for you, just don't get your hopes up about them making you lose weight.

Nutritional Customs That Work
If you've had the chance to read the free report I wrote for grrlathlete.com titled "The Ten Day Diet Solution" then you know I am a fan of nutritional customs.
I think that setting rules that help us control what we eat by controlling how and when we eat is a great strategy for overall health and well being, and is a great (and easy) way to lose weight.
This is why I get angry when so called 'nutrition gurus' rip on nutritional customs.
Take the example of 'not eating after 7 pm' or 'not eating carbs after 7 pm.'
This is a ritual practiced by many of the fitness models I have had the pleasure of meeting over the years. Many of them follow this custom during the periods when they are preparing for a fitness competition.
No matter their reasoning, the simple fact is that this custom allows them to lower their caloric intake. There's no magic. It has nothing to do with increased fat burning, or decreased fat storage during nighttime, it is just a method of "intake" control. And it works because they like it, and its easy.
What bothered me was that a couple of years ago, while in a seminar session at the annual Canadian Society for Exercise Physiology conference, I heard a supposed nutrition guru explain why this custom was 'ineffective'.
With as much Show-man 'Bravado' as he could muster, he pointed out all the reasons why the "science did not support this fallacy" (While at the same time, pushing his own ridiculous weight loss diet plan).
The fact of the matter is, if people like to follow this nutritional custom, and it helps them eat less during the day, and stay in control of their nutrition plan, then it works. Plain and Simple.
Sometimes, so called gurus can blind themselves with science and lose site of the big picture. If it works for you and you are happy with it, then keep the custom.

Health Claims and Advertising
This morning I realized that yesterday's blog may have been a little confusing, so I made a trip to the grocery store so I could find some examples.
Luckily, I found two really good ones.
Firstly, on the side of a certain cereal box is the following statement, (it appears besides the Heart and Stroke Foundations "Health Check" symbol.)
"This cereal is low in fat and is a source of fibre. Emphasizing grain products such as cereals and increasing fibre intake are components of healthy eating. This cereal financially supports the Health Check education program of the Heart and Stroke Foundation. This is not an Endorsement"
Sounds pretty healthy to me. In fact, after reading this statement and noticing the 'Health Check' symbol I might buy this cereal for my kids.
However, at closer inspection we realize that "financially supports" means "gave money to" and "this is not an endorsement" means "This symbol does not mean our cereal was 'approved' by the Heart and Stroke Foundation".
My next example is on my bag of Oatmeal.
There is a little green check mark on the front of the bag, with a statement that the product is a "Smart Selection Made Easy". What they don't tell you is that the "Smart Selections" symbol is actually a trademark of the Oatmeal company.
The problem I have is that both of these products are descent food products. And, these advertisements are not misleading per se. However they do take advantage of the fact that not all of us may have the knowledge or the time to dig around and find the true meaning behind these claims.
This is why I think its best that when shopping for food, stick with the strong silent types that don't have to 'scream' about their health benefits.
No one ever questions whether or not eating an apple or a pear is good for you.

Snake-Oil Traders
I Just finished reading an article in the Skeptical Inquirer by Edzard Ernst called "Snake-Oil Traders," that describes the current practice and marketing of Complementary and Alternative Medicine in the UK.
It was a well written article, with some very interesting points regarding how the British Medical Association and the General medical Council governs the ethics of advertising in medicine.
Specifically, The British Medical Association takes the stance that people who seek medical advice are vulnerable to exploitation. Then they go on to say that the information doctors publish "Must not make unjustifiable claims, offer guarantees of cures, or exploit patent's vulnerability or lack of medical knowledge."
It was the last line that really caught my attention and made me think of the functional food and supplement industry.
Have you noticed how technical and scientific many of the current health claims are becoming in functional food and supplement advertising?
As more and more people are spending time worrying about their health, perhaps its time we adopted a stance that punishes companies from using marketing that is not misleading, but may be exploiting the fact that we might not all have the medical knowledge needed to make educated decisions about the claims in food and supplement advertising.
When it comes to health claims and advertising, I believe many companies are trying to 'blind us with science', thinking that if they use big enough words, then we will have no choice but to believe their claims.
When it comes to advertising, I prefer my 'functional foods' to be the strong silent types. The ones who don't have to yell and scream about their "awesome health benefits". You know, foods like oranges and bananas.
As Michael Pollan says, the more health claims on a product, the less healthy it probably is.

I got my A$$ Kicked By a 260 Pound Monster!
It's true!
It's finally getting nice outside up in Canada, so I decided to move my workouts outdoors.
I absolutely love this time of year, because in my opinion, training outside is about a thousand times more fun that training in a gym.
However, I forgot just how gruelling pulling sleds can be, and after only 3 trips of about 50 yards, my legs were burning and I was exhausted.
Lesson learned, nothing gets your conditioning up quite like pulling sleds.

Nutrition from 1972
Just a quick post today to share an excerpt from a book I just read while waiting at my Doctor's office. (He was running a little behind, so I started leafing through some of his older text books).
Here's a piece from a Nutrition text book published in 1972 called "Human Nutrition and Dietetics" by Davidson, Passmore and Brock (fifth Edition)
"The diet of an athlete should not differ from an ordinary balanced diet, except for the need for an increase in calories."
I couldn't agree more.
I have often said that with the exception of the calorie content, the diet of an athlete should be no different from the diet of an average person.
Usually when I say this, the "sport nutritionists" out there tend to get their noses all out of joint, but when I re-word it as, "The diet of an average person should be the same diet as an elite athlete, just with different total calorie intake." they seem to be OK with it.
Go Figure.
The next excerpt was equally as interesting...
(Still talking about the diet of athletes)
"High energy diets should contain large amounts of fat unless they are to become very bulky. Physical activity prevents the disturbances in blood lipids which commonly arise in sedentary people on high fat diets, and large quantities of fat in the diet will do no harm to physically active people."
A couple interesting points from this statement.
Firstly - "Unless they are to become very bulky"
Since fat does not make the diet nearly as bulky as carbohydrates or proteins, I'm going to assume that the authors are referring to the athletes in question. This suggests that 35 years ago, we seemed to have not yet developed the "Fat makes you Fat" mentality we have today.
Secondly - "large quantities of fat in the diet will do no harm to physically active people."
This interesting quote is sure to raise many eyebrows, as it still has me thinking.
While I believe this statement is true, I will admit that my strengths are nutrition, metabolism and body composition, and not blood lipids and cardiovascular disease, so I will run this by some people who have a little more knowledge than I do in this area.
So the recommended diet for an athlete 35 years ago was to eat a healthy balanced diet, but add some more fat to keep your calories up.
Sounds perfect to me.

Why Starbucks is Like Godzilla
On Monday I had a chance to catch up with one of my good friends who has spent the last five years living in Japan. He was back in Canada for a wedding, and since I haven't seen him in years it was definitely time to catch up.
Of course, the conversation eventually turned to Nutrition, and I learnt an eye-opening fact about some disturbing trends in Japan.
According to my friend, Starbucks is making a push to get a foot-hold in the Japanese market. Kind of like Godzilla, only without the death and destruction.
While this shouldn't be shocking to any of us (after all, while visiting China I saw a Starbucks INSIDE the forbidden city!), what is shocking is the effect that Starbucks is having on some of the Japanese nutrition customs.
In Japan it is a centuries-old tradition that you don't drink while walking.
And this poses a huge dilemma for the Starbucks crowd.
Since space is very hard to come by in Japan, many of the Starbucks shops are walk-up "express" versions with little to no seating. Basically, if you want your Starbucks, you are going to have to walk with it.
And guess what - People are walking with their Starbucks. Starbucks is single-handedly destroying centuries of Japanese tradition.
This is a perfect example of a soon-to-be extinct custom that once prevented people from eating while they are distracted. And it fits perfectly with the stories I have been telling you from the book,"Mindless Eating".
In this incredible book there are examples of many other mindless eating methods that have replaced our own nutrition customs. (i.e. If you read it you'll find out what eating in front of the TeeVee has done to us, rather than eating around the dinner table).
So not only are these eating customs "sacred", but they also serve a purpose. In fact, I believe that the disappearance of traditional eating customs is one of the largest factors in our current obesity problem.
If you don't already have your own set of "nutrition customs" perhaps it's time you thought about adopting some.
Here is an easy one for all of you commuters out there. For the rest of this week, do not eat in your car. You can drink, just no food. This rule will help you keep your car clean AND save you from some mindless distracted eating.
Give it a try and let me know how it goes.

Is There a Conspiracy to Make Us Fat?
Thanks to some very frustrating airport delays yesterday, I managed to finish off "Mindless Eating" by Brian Wansink.
This book did not disappoint me. Almost every page had great facts about the way food is marketed and the factors that make us decide to eat. This book is definitely in my list of top-ten must-read nutrition books.
I've been racking my brains trying to figure out the top lesson I learnt from this book so that I could share it with you, and I think I have it.
You know how everybody these days seems to be blaming the food companies for our obesity problem? - As if it's some giant conspiracy?
Well the number one thing I learnt from "Mindless Eating" is that there is no "fat conspiracy".
Food companies do not care if you EAT their foods. They only care if you BUY their foods and continue to BUY their foods.
The people at McDonalds don't care if you buy a happy meal, turn around and throw it in the garbage, just as long as you buy the happy meal.
Also, food isn't designed to be "fattening" (Whatever that means). Food is designed to be inexpensive for the companies to make and desirable enough for you to repeatedly purchase.
This is the great conspiracy. Yes food companies, restaurants and shopping centers go to great lengths to figure out how to make us BUY there food, but we are the ones making the decision to EAT the food.
And this is where some of the great ideas from "Mindless Eating" come into play.
Do you remember the picture of the four glasss I posted on my blog on Monday (look below)? Every glass in the picture contains 1 and a half cups of fluid, except for the small squat one, it has 2 cups.
This is reffered to as the "horizontal-vertical illusion". If you picture an upside-down capital "T" where both the horizontal line and the vertical line are the same length, we will always see the vertical line as being longer.
So if you were to fill the small cup to almost the top, like most of us do, it would contain a little over 2 and a half cups of fluid.
So a morning cup of orange juice could actually be a morning 2-and-a-half cups of orange juice. This could account for an extra 33 grams of sugar and 165 Calories!
This is just one great example of how our assumptions combined with some excellent marketing get us to buy more and consume more. If we can become more aware of these "overeating ques" that are around us every day, then we can be more aware of ways to avoid them.

Mindless Eating
I'm about half way through a great book called "Mindless Eating" by Brian Wansink.
Normally, I don't post about books until I have finished them, but since I have already learnt so many things from this book that I want to share, I figured I'd make an exception.
Mindless eating explores all the reasons why we eat, and more importantly to me, all the reasons why we can't stop eating.
From our inability to estimate the calorie content of foods, to the lies our eyes tell us, I've found this book (so far) to be fascinating.
As an example, please check out the picture below, and try to figure out which glass has the most liquid and which has the least...
Check back later in the week and I will tell you which glass has the most and why our eyes and our stomachs play tricks on us.

The 3 hidden gems I found at the Farmer's Market
Last week I attended my first Farmer's Market of the summer. Granted, it's not quite summer up here in Canada, but it's getting close.
If you have never been to a Farmer's Market, I can't stress enough how great these places are for people who are trying to eat healthy. When it comes to the benefits of a Farmer's Market, It can all be summed up in two words - Fresh Food.
Fresh produce, fresh dairy and fresh meat. And these days fresh anything is worth it's weight in gold.
You see, in the big money world of grocery super stores, one thing rules supreme and that's shelf life.
Companies go to great lengths to be innovative in their packaging and formulations in order to squeak another couple days of shelf life out of their products before they expire. Whether it's ultra-high heat pasteurization of dairy products, or the sodium benzoate and potassium sorbate found in almost all bottled drinks these days, the "shelf life wars" are changing the look and feel of our foods.
The longer they are on the shelf, the more likely you will buy them.
From milk to fruits and vegetables, the product with the longest shelf life wins.
However, my adopted Nutrition mantra of "The quicker it goes bad, the better it is for you" suggests that we should be buying and eating foods that have the shortest shelf life.
My reasoning for this is that we are still discovering the compounds in food that benefit our health, and I'm sure it will be sometime before we actually have an exhaustive list. The more we discover, the more we realize that many of these compounds degrade quickly, and what might be present in fresh foods may not be present in some of the ultra extended shelf life versions you find in grocery super stores.
And this is where summer Farmers Markets are a great tool.
Make it a priority this summer to do most, if not all of your shopping at farmers markets, paying special attention to pick the freshest in-season fruits and vegetables that you can find.
Finally, here are the three hidden treasures I found last weekend.
One- Goats Milk Yogurt
Why is this a hidden treasure? Well for one, it tastes AMAZING, but more importantly compare the ingredients to the leading off-the-shelf yogurt.
Goats Milk Yogurt: Pasteurized whole goats milk, bacterial cultures.
Leading Yogurt: Skim milk, cream, sugar, concentrated skim milk, fructose, milk and whey protein concentrate, corn starch, gelatin, modified corn starch, active bacterial cultures, natural and artificial flavors, locust bean gum, natural & artificial colors, malic acid.
Quite the difference!
Two- Grass Fed Meat
The rumors are true, this stuff tastes Great!
More importantly, these steaks come from cows which were allowed to graze on a pasture, as opposed to the beef from corn fed cows. The difference, (Other than no hormones and no antibiotics in their feed), is that the meat from grass fed cows is actually higher in polyunsaturated fatty acids than the meat from cornfed cows. Nutritious and Delicious
Three-Locally grown Produce
Almost all of the produce at Farmer's Markets are locally grown. Why does this matter? It matters because this means you strawberries didnt take a 1,000 mile drive to get to you.
And there you have it, the 3 hidden gems that will make me go back to my farmers market this Saturday.

How to Win the Fat War
3,900 - This is the amount of food calories produced every day for each American citizen.
Think about this number for a minute. 3,900 calories is well over a thousand more calories than almost any of us will ever need in a day- but they are being produced so someone has to eat them.
This is what I like to call the North American paradox. Food companies and food producers need us to consume more and more calories to keep their profits coming, yet we want to consume less and less calories to maintain our health.
This is why it is not an exaggeration when I say it is a battle to try and eat less food and to make sure that the foods we do eat are healthy foods.
The best way to win this battle? Always remember that the foods you see in convenience stores and gas stations are there because someone wants you to buy them and has figured out what colors, names, and sizes will make you notice their products.
So the way to win this battle is by not being a "good little consumer".
Try your best to buy only planned foods - The foods you plan to buy during your grocery run.
Resist all unplanned purchases...gas stations, convenience stores, vending machines and checkout lines...these are all examples of places where we typically make unplanned impulse food buys.
Make this one adjustment to your typical daily routine and you are on your way to winning the fat war.

3 "Magic" Fat Loss Ingredients
Every morning I go through the exact same routine.
I get up. I make some oatmeal. Clean the kitchen. Go up stairs. Brush my teeth. Turn on my computer. Check my email. Then I laugh (or sometimes cry) while reading all of the new stories about the latest and greatest "fat loss" ingredients.
It is an absolute mystery to me why, after over 20 years of failed promises, we still turn to magic ingredients and magic foods for fat loss.
What shocks me even more is that we are still hoping to find something we can eat that will cause us to lose fat. It is almost becoming an oxymoron.
We are looking for something to consume that will make us consume less!
Here are just some examples of magic foods and ingredients in the new today:
Recent research (performed in a test tube) suggests that extract from Chilli peppers may stop fat growth. According to this research Chilli extract may hold the key to preventing immature fat cells from developing into mature fat cells.
In a different study, it was suggested that spearmint tea can not only lower a man's sex drive but can also decrease the amount of hair on a women's body. (Admittedly, this isn't fat loss research but if you think the body builders in your gym smell bad now, wait till they read this research and stop brushing their teeth for fear that they may be lowering their T levels!)
Finally, more research shows that dairy calcium (but not calcium supplements) can cause a decrease in the amount of fat in your blood after a meal.
I can't really tell you too much about this study because I stopped reading after the first page that mentioned that the study was funded by the Danish Dairy Research Foundation and the Dutch Dairy Association!
A Dairy Foundation and a Dairy Association funded the study, and the study found that dairy calcium, but not calcium supplements had weight loss benefits? Please.
Now honestly, there is some merit to this research. Eating more spices on your food is definitely a good idea. Eating foods that contain calcium is also a good idea.
However, thinking that taking chilli extract pills or consuming 3 bowls of ice-cream per day will make you lose weight IS NOT what you should be taking away from this research. (Nor is skipping your morning tooth brushing!)
If you want to lose weight there are only three things you need to do, and you don't need to read any research to do them.
Firstly, find a nutrition plan that works for you.
Secondly, get active. And I don't mean walk on the elliptical for half an hour every other day, I mean get a real work-out program and challenge yourself.
The third and last thing you need to do is to stop (or don't start) falling for the media's version of the latest and greatest fat loss research. It will only lead to disappointment and is usually a very poor and hyped up version of what the research was really telling us.
These are the real 3 "magic" fat loss ingredients!

The Newest Diet Study - What does it really tell us?
By now, you have probably heard about the latest study – You know the one that “proves” that the Atkins diet is superior for weight loss?
So let me just clear this up right now. The results of this study prove one thing and one thing only – diets work.
In fact, after reviewing this study, and all of the commentary, posturing, crying and bickering that it has caused, I have come to the conclusion that this study proves that the very best thing you can do for weight loss is:
Eat less, but enjoy the foods you eat. Eat lots of fruits and vegetables, and lots of herbs and spices. And maybe most importantly, spend less time stressing over the types of food you are eating
In other words - Cut your calories in a way that works for you. ( It might take a bit of trial and error, but it will be worth it.)
Now here are the facts from the study…
311 overweight, pre-menopausal women were divided into four groups and were asked to follow one of the following dietary programs: The Atkins diet, the Zone diet, the LEARN diet or the Ornish diet.
Each woman was put in one of these groups and received a copy of one of the popular weight loss books. Each woman then met with a registered dietitian once per week for 8 weeks learning “the ins and outs” of their assigned diet.
After these classes the subjects were “set free” to follow the diet for 12 months, with the exception of a couple of visits to the lab and some unannounced phone calls where the researchers asked the subjects to recall what they had eaten in the last 24 hours.
What happened?
As expected, all 4 groups ate fewer calories during the study than they were eating before the study – so all diets “worked” to help cut calories.
And each group lost weight with most weight loss happening in the first 2 months. (After this point for all diets, the weight loss tended to slow or even creep back up).
The Atkins style diet had the best weight loss during the first 2 months and over the 6-month study. That’s why you see Atkins being crowned the king of weight loss diets.
However, by end of the 12-month study, the results tended to “even out”. And by the end of the study, the Atkins diet was really only better than the Zone Diet (which isn’t a bad diet on it’s own).
And you know what? The total weight loss wasn’t that impressive – with the Atkins dieters losing 12.5 lbs in 6 months. That’s 0.5 lbs per week. Good, but not eye-popping results.
But here’s the kicker. It’s hard for me to understand how overweight woman (averaging 180 pounds and over 40% bodyfat) can eat less than 1400 calories per day for 6-months and lose only lose 12 and a half pounds. There is something very wrong here.
Looking at the data, I noticed that all of the diets saw a small slow increase in their calorie intake over the year. And honestly, this was probably due to huge errors in dietary recall. Most people can’t accurately describe what they had for lunch, so this measure isn’t worth the paper it was written on.
Dietary recall is a scientific method for measuring caloric intake that has been under a large amount of scrutiny in the past years.
Imagine having someone call you on the phone and ask you to describe all of the foods you had eaten over the day. Imagine the types of mistakes in sizes and types of food that could be made in this type of interpretation and then imagine the kind of effects that this could have in a scientific study.
Now also imagine that you SIGNED UP for a weight loss study, so you are already motivated to eat less and you are also insecure about the amounts and types of food you eat.
For true research, diet recalls are a horrible tool. Plain and simple.
I also noticed that none of the diets were true to their form.
Take a look at the “high protein Atkins style diet”. After 2 months the subjects reported a protein intake of 95 grams. But at 12 months it was down to 82 grams. How is this high protein? It’s not even 0.5 grams per pound of bodyweight!
And check out the “Ornish Low fat diet”. At 2 months fat made up 21% of their caloric intake, at 12 months it made up 29.8% of their calories. This is a far cry from the 10% that Dr. Ornish advocates.
Because the subjects had such a hard time sticking to the diet plans, I don’t think that this trial proved that any one diet was better than the other. It did prove that the diet with the lowest carbohydrates had the quickest weight loss. And it did show that diets high in fat can still have health benefits. Most likely, the health benefits are the result of the reduced calories and the associated weight loss as all the diets were associated with health improvements.
Of course, proponents of each diet are all crying foul. They’re complaining about the study design, the subjects, the poor compliance to the diet plans…but most importantly they’re complaining because they make money by selling you their programs!
Its funny…Dr. Ornish said that the study was flawed because most participants couldn’t follow the Ornish diet. That doesn’t make the study flawed - its makes the diet flawed.
And that’s exactly what this study proves…it is very difficult to follow these prescribed diets. These people don’t know you. They don’t know what you like to eat or what you do for a living. They simply design a diet that makes a lot of sense on paper, and prescribe it as a cure all.
The bottom line is…this study still not help end the debate over which diet works best because there IS NO DEBATE. Eating less works! End of story. The rest of it is just people making simple diet advice into confusing pseudo-science so they can sell you their programs.
Eat less, but enjoy the foods you eat. Eat lots of fruits and vegetables, and lots of herbs and spices. And maybe most importantly, spend less time stressing over the types of food you are eating.

Why French women don't get fat
As part of my responsibilities as a nutrition critic, I read a lot of diet and nutrition books.
Admittedly, there are so many diet books out there it is almost impossible for me to read ALL of them, but every so often, when one hits the the best sellers list, it's time for me to visit my local book store and get my read on.
Last week was one of those times. After over hearing some very positive conversation at my local coffee shop I realized I needed to get my hands on a copy of "French women don't get fat" by Mireille Guiliano.
After a weekend of reading, I've finished the book, and have this review to offer.
I found this book to be unlike most of the other diet books I have reviewed lately. There is no hokey psuedo-science, no clearly-defined plan, and no lists of "magical foods" that you have to avoid or have to eat.
The premise behind the book is fairly simple. According to the author, French women are not fat - Therefore we should eat like the French.
Now, if you remove all of the stories about life in France, some useful recipes and some sporadic uses of the French language, then you are left with one easy message:
"Eat less, but enjoy the foods you eat. Eat lots of fruits and vegetables, and lots of herbs and spices. And maybe most importantly, spend less time stressing over the types of food you are eating."
Sound familiar? This is close to exactly the message that I have been promoting on this blog and in my articles for grrlAthlete.com
Now you may be thinking that this is this some coincidence, or that maybe I have met Mireille Guiliano, and I can tell you that neither of these are true.
I have never met Mireille (However, I would like too), but the similarity in these messages is not a coincidence.
The reason that our messages are almost identical is because they work.
Your absolute best tool for creating a great nutritional diet is eating less but enjoying the foods you eat. Follow this by eating lots of fruits and vegetables, and lots of herbs and spices and you are well on your way to a diet that is near perfection. And once you stop stressing over the types of food you are eating, well at this point you are golden.

Is it time to give up on Low-fat foods?
We are surrounded by low-fat foods.
Nearly 10 billion dollars a year are spent advertising low-fat foods - Trying to convince us that we should buy them because they are "good for our health".
It was in the early 1980's when our government suggested that we cut back on our fat intake. Since then food companies have been in "product-development overdrive" churning out low-fat foods.
From low-fat cookies and brownies, to low-fat cheese and yoghurt, you can find a low-fat version of every one of your favorite foods in your local grocery store.
However, before we accept the "low-fat equals good healt message", there are a couple of important things we should think about when it comes to the effectiveness of low-fat foods:
1) If you take the fat out of food, you have to replace it with something. Binders, emulsifiers, bulking agents, and yes sugars like high fructose corn syrup are all used to replace fat. What's more, the foods that traditionally have higher fat, like cheese and yogurt, are the ones that need the most additives once the fat is removed.
2) The low-fat food trend is only 25 years old. And in the last 25 years, as low-fat foods dominated our grocery stores, obesity, diabetes and cancer have all been on the rise. The idea that simply switching to low-fat foods will help us maintain a healthy weight has failed miserably.
3) A recent study examining the lifestyle habits of 18,555 women found that women who ate at least one serving of high fat dairy every day appeared to reduce their risk of ovulatory infertility. While this is only one study, it does have a very large subject group and does lead to the idea that fats may not be as bad for you as once thought. Indeed, even saturated fats may actually have some health benefits.
4) The scientific evidence behind the idea that low-fat eating is healthy is actually pretty weak. It was in the 1950's that a small group of people began to popularize the idea that low-fat eating was healthy eating. Since then hundreds of millions of dollars have been spent on research trying to prove the idea was correct. The results of this research have been so surprisingly weak that it is starting to make many scientists skeptical of the supposed damaging health effects of fat.
5) The "fat is bad" message is very oversimplified. Take butter for instance. Yes it is a source of saturated fat, but it is also almost 25% monounsaturated fats, of which almost 80% is oleic acid, the same type of fat found in olive oil. There are many foods out there that have been wrongly accused of being simply saturated fat.
Bottom line - We need to stop trying blame obesity on the fat in our foods.
As a simple guideline- Eat less, but enjoy the foods you eat. Eat lots of fruits and vegetables, and lots of herbs and spices. And maybe most importantly, spend less time stressing over the types of food you are eating. These are probably the best thing you could do for your health.

What's Interesting about this study?
27 obese patients were subjected to a ten day fast consisting of 250 Calories per day. The Subjects were divided into two groups, a group that exercised and a group that did not.
After ten days:
- Both groups had similar weight loss.
- The exercise was well tolerated without problems.
- The loss of muscle was significantly less in the exercise group.
The authors concluded "This may indicate that muscular activity is useful in aiding adaptation to fasting and may orient weight loss preferentially towards fat mass."
While certainly not earth shattering...the part that is very interesting to me is that this study was published in 1975!
So, we had a vague idea over 3o years ago that exercise was needed to maintain muscle mass while dieting. Yet, nowadays we still argue about protein ratios, carb cycling and meal frequency and supplementation. Seems like something was lost in the last 30 years!
Simple truth - Just like Schrub et al. hypothesised over 30 years ago, if you are dieting and you want to preserve muscle mass, lift weights.

How to Shed Body Fat
This time last year I was almost half way through dieting for a bodybuilding contest.
That's right. As embarrassing as it is, I have been on stage, in a pair of glorified speedos, posing for a table full of judges.
You can call it a freak show, you can call it a bikini contest or you can call it pure vanity. I admit, I make fun of these competitions too.
I decided to compete last year to make sure that I could transform my body. After all, I'd be a hypocrite if I wrote in this blog about nutrition and weight loss if I've never actually taken my own body to the extremes of dieting.
And to be honest, it was one of the single best things I have ever done, because I recorded a journal of every single day of my diet.
And now whenever I feel like I need a little motivation and direction, I can simply look back at what worked for me.
I know I say this all the time, but it is worth repeating - A journal is your single best tool for getting in shape. It doesn't have to be super detailed, just a quick outline of how each day is going.
Here is an example of one of my pages...it's mostly chicken scratch that only I can understand..but it tells me exactly what I need to know.
Basically, the yellow highlighted stuff is my workout...and the rest is notes. From this one page I know that I didn't want to go any heavier on dead lifts, that my diet was going well, and that I tried step-ups, but preferred split squats for this particular workout.
It took me about two minutes every day to fill this out. I never did it in the gym..often I filled it in during a break at work, or when I got home that night. But it's proved to be extremely valuable for me.
A couple of months after the contest, I summarized some key notes about the whole experience.
- I had great results using intervals.
- I had great results using a whole body split.
- I had poor results using a bodybuilder type routine.
- I was able to maintain my strength during the whole diet.
- I was able to maintain my activity level during the whole diet.
- Cheat days are a waste. I found no benefit from them at all.
- 1,200 Calories was a little too low for me, but 1,500 to 1,800 worked perfectly.
- I lost almost no muscle during the entire diet.
- Avoiding simple sugars seemed to make a very big difference towards the end of my diet.
Great reminders for whenever I felt I needed to look back at what worked for me. This is why I view keeping a journal as your number one tool for weight loss.
Another great bonus was that during this time I had regular access to a BodPod..a great device for tracking body fat and lean mass changes that is very easy to use and very accurate.

Every Thursday I would take my measurements with the BodPod, and then chart my changes in a spread sheet.
This is the second most important tool for weight loss - measurements.
Now, you don't need a BodPod to track changes - a scale, measuring tape and a digital camera will do just fine. In fact, I used the pictures I took with my digital camera more than I used my Bodpod readings to track my changes.
If you photograph, weigh and measure yourself at the same time every week, this will give you a great way to look back and track any changes that were made.
Once you get in the habit of monitoring your progress by recording a journal and measuring your body, losing weight becomes much easier, because you are no longer guessing at what works and what doesn't work. You can simply look at your records.

Buying Weight Loss
I apologize for the lack of posts; it's been a very busy 2007 so far.
For me, 2007 has been the year of meetings. It's been one after the other for almost all of January. Usually, they involve a good amount of food, and a lot of conversation about nutrition and the food industry.
In fact, I just finished a meeting today where I had one of those "hmmmmm" moments.
You see, it dawned on me while discussing the latest dieting trends that we have done a great job of creating an "industry" out of weight loss. And, by "we" I don't mean some evil corporate conspiracy or some secret group of executives. I mean you, me, and everyone else who make up the buying public.
Somehow, we've convinced ourselves that in order to lose weight, eating less is not the answer. Instead, we've decided that the key to losing weight is eating foods that make us lose weight.
It's as though we are addicted to buying. To purchasing and consuming. In general we have a hard time excepting that "taking away" is the answer. We would much rather "add".
Sure, this keeps us as good little consumers and keeps the economy going, but a quick look at the stats reveals that it certainly doesn’t make us any leaner. In fact, the opposite is happening. We keep consuming and, as a population, we keep getting bigger.
So here is my solution - Instead of worrying about which green tea to buy, and what specific type of grapefruit you are going to eat, which diet you are going to follow, and which fast food is "healthiest", make a rule that outside of the grocery store, you will not pay for food. I don't mean steal. I just mean don't buy anything extra that day.
We already know that just because you are hungry, it doesn’t mean your metabolism is slowing down, or that you are breaking down muscle (Unless you haven’t eaten in over 3 days!). For the most part, it simply means you are used to eating at that time.
So forgo the snacks in the car, and the coffee stop on the way into work. I’m sure that if you can avoid buying any extra food for an entire month, you will see significant weight loss. Despite all the gimmicks and trends, simply eating less is still the best, most effective answer.
Give it a try, but take a positive approach. Go into this experiment thinking that you do not need to buy extra food. That you will not feel bad, or sluggish. That it will not affect your workouts or your stress level. Stay positive, and avoid purchasing anything other than your groceries.

Deconstructing Nutrition – The Thermic Effect of Food
Before I get started let me just say that this was by far the most difficult research project I have done to date.
The amount of misinformation, conflicting results, and misinterpreted data out there on this topic is amazing.
For this reason, I have had to break this topic up into three different parts
PART I
The thermic effect of food is the energy your body requires to digest, absorb and dispose of the nutrients that you eat. It is often abbreviated as TEF and is usually sited by diet gurus and fitness experts as the reasons why you should or shouldn’t eat a certain way.
Through a quick scan of the internet, I found the following claims:
- The more often you eat, the higher your metabolic rate
- Protein increases your metabolism by 40%
So it would make sense that eating multiple small high-protein meals would be the best way to increase your metabolism.
While this theory sounds great, let’s look at what the research has found…
Firstly, the one thing that all the papers I read agreed upon was that the number one factor that affects your TEF is the total amount of calories you eat.
Researchers have calculated TEF to be roughly 10% of your caloric intake.
Therefore, if you eat 1,000 Calories, you raise your metabolism by about 100 Calories and if you eat 10,000 Calories, you will raise your metabolism by about 1,000 Calories.
The majority of the thermic effect occurs in the first hour after eating, but depending on the size of the meal the effect can last from anywhere between 5 and 24 hours. It seems that the thermic effect will last until all the calories from your meals have been metabolized.
This leads us to the theory of eating frequent small meals.
From what I can tell, the idea that food frequency affects the amount of calories you burn is very debatable.
A few papers have found that eating one large meal has a higher thermic effect then many small meals. And a few papers have found that eating several small meals has a larger effect then one large meal. The rest have found no difference.
And to me, this makes the most sense.
If you eat 2,000 Calories, you will have to burn about 200 calories just digesting, absorbing and disposing of the nutrients you have eaten.
It does not matter whether you ate all 2,000 Calories at once, or spread them out through multiple small 500 Calorie meals. The total volume of calories remains the same and therefore so does their effect on your metabolism.
So far, the Thermic effect of food can be best summed up as –
“Eating increases your metabolism”
For the average person, eating around 2,500 Calories a day, the Thermic Effect of Food will increase your metabolism by between 200-300 Calories.
Here’s the kicker - If total calorie content is the best predictor of your TEF, it’s not as if you are going to eat an extra 5000 calories so you can burn an extra 500!
Luckily, there still may be ways to affect your metabolism through the foods you eat. In Part II I will break down the effect the different macronutrients have on your metabolism.

Sweet Misery
Here is a link to a very interesting movie on the history and politics behind Aspartame.
I will warn you ahead of time that the movie is very one-sided, and many of the claims that are made about the dangers of aspartame seem to be greatly exaggerated. However, it is also very eye opening.
Even if the claims are greatly exaggerated, they still describe a very scary political battle that was behind the legalization of what is probably the world's most famous artificial sweetener.
PS- By posting this movie I am not verifying or agreeing with its views or opinions. I am condoning it as an educational piece of work for you to assess and to use as a tool to build your opinions on what you choose to eat and what you choose not to eat.

What's up with gum?
The other day, after watching the movie "Sweet Misery" I started thinking about gum.
I've never been a big gum chewer, but I decided that I should go on a shopping trip and see exactly what is going on in the gum aisles these days. I was amazed by what I found.
Firstly...from what I could find at my local convenience stores, almost all gum contains aspartame, sucralose, or acesulfame-potassium (remember I'm in Canada, so the ingredients may be different then in other countries).
The interesting thing is that this includes the "sugar" gums - Even the well known "bubble gums" contain both sugar AND artificial sweeteners!
We have gotten to the point where chewing on straight sugar isn’t sweet enough anymore, we have to add artificial sweeteners to sugar to make it sweet enough for our tastes!
Secondly, and probably most shocking to me, was that several of the "bubble gums" contain hydrogenated vegetable oils in their ingredients. I had no idea that there could be trans fats in bubble gum!
Just another reason to read the labels on everything you put in your mouth.

Give up on fighting fat?
I came across a very interesting article the other day. I've been wrestling with it's suggestions for a while now and am still not sure whether or not I agree with any of them.
Take a look below and let me know what you think...but please keep in mind that this article is full of personal beliefs from the author and is not to be confused with my beliefs or with scientific fact.
End the War on Obesity: Make Peace With Your Patients
Linda Bacon, MA, PhD Medscape General Medicine. 2006;8(4):40. ©2006 MedscapePosted 11/27/2006
Your patients are desperate to lose weight. Given the presumed health imperative, you feel justified in supporting their goal. You encourage calorie restriction and/or exercise.
The "weight problem," however, never goes away. Face the facts. We're losing the war on obesity. The"common sense" approach just isn't working. Weights are increasing, particularly among dieters, and weight preoccupation and eating disorders are also on the rise.
Challenge your assumptions.
1. Weight has been greatly exaggerated as a health risk. Consider mortality. Except at statistical extremes,BMI only weakly predicts longevity. Many studies indicate "overweight" people live at least as long as"normal" weight people.[1-3] "Overweight" may even be ideal for longevity.[2]Consider morbidity. Epidemiological studies rarely acknowledge confounding factors like fitness, activity, nutrient intake, weight cycling, or socioeconomic status. Studies that do control for these find increased morbidity disappears or at least is sharply attenuated.[4]
2. Sustained weight loss is not a practical goal, nor is it well established to improve health. The vast majority of people regain lost weight,regardless of whether they maintain their diet or exercise programs.[5] And no one has ever proved that losing weight prolongs life. Some studies actually indicate that intentional weight loss increases the risk of dying early from certain diseases.[6-11]
3. Health improvements can result from improved health behaviors, regardless of whether weight is lost.[12]Improvements in insulin sensitivity and blood lipids have even been documented to occur in people who actually gained body fat during an exercise program![13,14]
There's an alternative to the war.
The new peace movement is called "Health at Every Size," and it acknowledges that health habits are more important than the scale.[12]Participation is simple. Quit hassling patients about their weight. Stop prescribing weight loss. Encourage people of all sizes to change focus from weight to health. Support everyone in appreciating their bodies and incorporating healthy lifestyle habits.That's my opinion. I'm Dr. Linda Bacon, Nutrition Researcher, University of California, Davis, and Nutrition Professor, City College of San Francisco.

Deconstructing Nutrition - When you don’t eat, your metabolism slows down
When you don’t eat, your metabolism slows down.
This "nutrition fact" says that when your caloric intake is too low, your metabolism actually slows down. It has been referred to as “starvation mode” and is the basis for the current trend of advising people that they should eat every couple of hours, never skip meals, and never cut your calories too low while dieting.
But is it true?
To examine this truth, I decided to look into what happens to a person’s metabolism when they fast for a short period of time (between one and three days).
The first study I reviewed had six healthy male volunteers fast for 3 days. During this fast, the researchers measured the changes in the subject’s metabolism at 12, 18, 24, 20, 42, 54, and 72 hours of fasting. What they found was that there was no significant change in energy expenditure during any of the 7 time points. So from this study we can say that a 3 day fast in men does not cause a decrease in metabolism.
Already this evidence goes against the idea that if we don't eat every couple hours our metabolism will slow down.
The second study I reviewed had 8 men and 8 women fast every other day for 22 days straight. There was no significant change in the subject’s metabolism from the start to the end of the study. From this study, we can say that fasting every other day for a period of 22 days results in no significant changes to a person’s metabolism.
So we now know that even if we eat sporadically for 22 days, most likely our metabolism won't be affected.
The third study I reviewed had 8 men fast for either 12 hours or 72 hours and then eat a meal. After the meal their metabolisms were measured for 12 hours. This study found that regardless of whether or not the men fasted for 12 hours or 72 hours, their metabolism for 12 hours after eating a meal was not significantly different. So this study shows us that a short term fast doesn’t affect your metabolism after you eat.
So even if we don't eat for 3 days, there is absolutely no change in the way eating effects our metabolism.
So from the research I was able to review, it doesn’t seem like short periods of fasting cause any negative effects on our metabolism. Nor does it affect our metabolism once we start eating again.
Since having absolutely no calories for a short period of time does not effect our metabolism, I feel safe in saying that the idea that you need to eat every couple hours in order to keep your metabolism “revving” is actually a nutrition myth and not a fact at all. Also, the phenomena of a “starvation mode” does not happen until after at least 3 days of fasting, if it actually even exists.

Deconstructing Nutrition
For the next couple weeks I will be posting about the idea of “Deconstructing Nutrition”.
My plan is to take many of the things that we believe to be the known facts of nutrition and check their accuracy against the actual scientific findings. Think of it as doing fact checking for the big book on nutrition.
I’m going to start with what I think is the absolute best place to start when studying nutrition – fasting. By studying fasting we learn what happens to the body when there is zero nutrition being supplied. Once we understand this, we will be better able to understand what happens to the body when we add nutrition.
Stay tuned for the first post in the Deconstructing Nutrition series.

Nothing to do with Nutrition
I reserve the right to every once in a while talk about something other than nutrition. Especially when it's a concept I need some help on.
I'll give you the background.
Two weeks ago I was at a DVD photo shoot with Craig Ballantyne and John Barban, running through a bunch of great body weight exercises with our athletes for an upcoming grrlathlete project.
About half way into the shoot Craig had the athletes do a bunch of "siff" squat and lunge variations. These are variations where you perform a normal squat or lunge, but you stay on the balls of your feet through out the exercise.
I didn't think much of it until the other day when John and I were at a meeting with a good friend of ours who is a bio-mechanist. During our conversation, we started talking about running and jogging, and our bio-mechanist friend mentioned the incredible stress that is placed on your spine during a typical heel strike (think about how your heel hits the ground first when you are running - that's a heel strike).
Then today, I was at my Krav Maga class, and I couldn't help but notice that when you are sparring, and moving around, you are always on the balls of your feet!
So this all started me thinking, if almost all athletic activity involves us being on the balls of our feet, why do we train flat footed when we are working out?
Now, my main "thing" is nutrition - It's what I know best. I love working out, and exercise science, but for questions like this I always go to the experts...
So hopefully I can get Craig, John and a couple of other people to chime in here and give us their thoughts...

The Omnivore's Dilemma
As the old saying goes “Eat like everyone else, look like everyone else”.
OK, I think I made that up, but it’s still true.
The way you eat is a large determining factor in the way you look and feel. For this reason I highly recommend that you read the book “The Omnivore’s Dilemma” by Michael Pollen.
In a very in-depth and systematic approach, Mr. Pollen investigates the history behind what we put on our plates, and the driving forces behind the food choices we make.
I suggested this book earlier in one of my emails for grrlAthlete.com, but now I consider it mandatory reading for anyone who is trying to eat healthy and live healthy.
The food industry is no different from any other industry -they want you to buy their product, and will tell you anything they can to get you to choose their product rather than its competition.
This constant barrage of "buy me" advertising creates a very blurry and muddled message, that leaves people confused about what they should and should not eat.
I'm often asked what's the best way to beat the obesity epidemic. Well, in my opinion, you can forget about fad diets and you can forget about drugs, because being an informed consumer is the best weapon you can possibly have against obesity.
If you want to learn the history behind the foods that people eat and the way they are manufactured, then I highly recommend you read this book.

Forget about Cheat Days
Back in July and August, I spent a fair amount of my time up in Northern Ontario Cottage country.
The cottage is a great place to hide out and get some reading and writing done, but sometimes it can be a horrible place to try and 'eat clean'. It's very easy to rationalize a couple bad days at the cottage as "cheat days".
For some reason, body building magazines and fitness "gurus" love to promote the idea of cheat days.
It is more than common for a dieting bodybuilder to spend 6 days out of a week eating as little as 1200 Calories per day, and then on the seventh day eat close to 10,000 Calories!
People rationalize being a complete glutton for one day with excuses like "reloading" and "refueling".
These types of excuses are based on what I like to call fitness magazine science.
Fitness magazine science is all of the theories that appear in fitness magazines that have no scientific backing. Take for instance the idea that you can't store the excess calories from cheat days. This is rationalized by stating that your metabolism increases because of the massive amount of foods that you just consumed, and therefore you burn off all the extra energy.
A perfect example of a theory with no scientific backing.
But here is the real deal, and its plain and simple math. If your target calorie intake is a 500 Calorie deficit, and you lower your intake from 2,500 calories to 2,000 calories, then you have created a 3,000 Calorie deficit over six days.
Now on the seventh day, if you gorge yourself and eat yourself into the 6,000 Calorie range (which is hard, but definitely not impossible to do), you have just undone almost all the dieting you did during the week. There is no magic that makes those calories disappear.
Your body is amazing at storing energy. Sure, you lose a little to heat production and some ramped up metabolic processes, but at the end of the day the practice of cheat days is destructive. Like I said in my previous post on metabolism, the effect that food has on your metabolism is actually very small.
The idea that your body can't store all of these calories, or that somehow these extra calories don't turn into fat is a myth and a lie that will never die. It’s OK to reward yourself with ice cream every now and then, but full out cheat days with the soul purpose of gorging yourself should be avoided, plain and simple.

The Doctrine of Signatures
It is an unpleasant fact that science will always become outdated.
I am sure that a hundred years from now, schoolchildren will laugh at the principles we currently believe to be absolute scientific truths, just like how we now laugh at what was once "truth" centuries ago.
Take for instance the doctrine of signatures, which states that resemblance is a good indicator of effectiveness. If a particular plant resembles a human ear in its shape, then according to the doctrine of signatures this plant would have some sort of useful relevancy to the ear, perhaps being able to cure an earache.
While this now seems very arbitrary and somewhat unreliable, the doctrine of signatures still could be found in mainstream medical texts well into the 19th century and today is still the main principle of homeopathic medicine.
In fact, the doctrine of signatures can still be found in some nutrition myths that are still popular today. I know it's hard to believe that we would still use the doctrine of signatures with all of the research and scientific advancement that has happened in the world of nutrition, but take for instance fat, protein and cholesterol.
Many people still believe that eating fat will make you fat, that you need to eat large amounts of protein to build large amounts of muscle and that eating dietary cholesterol will make your blood cholesterol levels go through the roof.
Even though many of these "facts" are now largely disputed within the research community, people still believe them.
Why? You ask.
I think the reason is that these days science outdates itself so quickly that we no longer know what to believe. However, don’t blame the scientists for this.
You see, the job of science and scientists is to add to the existing body of research - To do their small part in answering the big question. However, most mainstream journalism and media need quick answers and they needed them yesterday! And this is where the major mistakes happen.
While scientists look at their work as something that helps answer a small piece of the puzzle, media looks at it as “THE ANSWER”.
This “jumping to scientific conclusions” can have dire consequences, as illustrated by one of my favorite articles, written by Gary Taubes and published in The New York Times back in 2002.
I think this is a very important piece of work that everyone should read, so please check it out by Clicking Here and let me know what you think of Gary's take on the last twenty years of nutrition research and policy.

Rules To Shop By
After a quick trip to the grocery store this morning, I realized how confusing it can be trying to pick out the good foods from the bad foods.
Food companies are jumping on the health claim bandwagon, and just about everything is now 'healthy this' or 'reduced that'. So here's a quick tip - The quicker it goes bad, the better it is for you.
Fruits, vegetables, meat and fish all go bad quickly, whereas cereals, boxed food and frozen food can last forever. Now there are some exceptions to this rule (nuts can last, especially if you keep them refrigerated), but generally this is a nice clean rule to go by.

Fat Wars, and Why I Cook with Butter
I've been following some very interesting stories in the news lately.
The first story concerns the City of New York. It seems that the Board of Health for New York City has recently voted to make New York the nation's first city to ban Trans fats at restaurants.
I found this story to be very interesting because as little as two decades ago Trans fats were introduced into our diet as a way to "save us" from the evils of saturated fats like butter and lard. And now research is starting to be published that questions the dangers of saturated fat, while trans fats are being banned by an entire city and David Kats, the director of the Yale Prevention Research Center is describing Trans Fats as "basically a slow form of poison!"
Then just this morning, I read on nutri-ingredients.com that an Australian company has just lunched a new "healthy milk" in China. This "healthy milk" has had all the animal fat removed and replaced with vegetable fat.
mmmmm yummy.
It seems to me that in our never ending quest to blame the foods we eat for our health woes, we keep making Frankenstein versions of food that inevitably come back to hurt us even more than the original versions.
My advice is the same as always. Eat lean and green. Fill your plate with as many vegetables as it can handle, don't be afraid to add as much color into your diet as possible, and try to limit the amount of food you eat that comes in a box.
And lastly, try cooking with butter. Yes butter. It tastes great, it cooks evenly, and at least with butter you know you are adding 2-3 grams of fat to your food, as opposed to some of the alternatives, in which you are adding 2-3 grams of 'who knows what' to your food.

Why Goat's Milk?
A couple of days ago in one of the grrlathlete newsletters I recommended that people give goat's milk an honest try (If you don't receive the grrlathlete newsletters, I've put a sign-up box on the top right column of my blog).
Since then, I've had more than a few people ask me to elaborate on why.
Well, firstly, because most of us have been drinking cow's milk since the age of two. Now, don't get me wrong, I don't have anything against cow's milk per Se, except that for many of us, we have been drinking it for more than a couple decades! So switching it up for a change may not be a bad idea.
Aside from the novelty, here are a couple more reasons that goat's milk deserves a fair test...
Goat's milk is the milk of choice in most of the world.
Because the protein in goat's milk has a different make-up than the protein in cow's milk, many people with cow milk allergies can tolerate drinking goat's milk .
Compared to cow's milk, goat's milk has similar amounts of protein, fat, iron, vitamin C and vitamin D. Goat milk has more natural vitamin A, more vitamin B , and less lactose.
Unlike cow's milk there is no need to homogenize goat's milk. While the fat globules in cow's milk tend to separate to the surface, the globules in goat's milk are much smaller and will remain suspended in solution.
So give goat's milk a try. I'm not claiming that it's some miracle food, but rather a tasty drink that many people are missing out on.

Metabolism Myths
For the longest time I believed that if you dieted to strictly your metabolism would slow to a crawl. This was Bodybuilding dieting gospel.
Skip breakfast? Now you've slowed your metabolism down for the entire day. No way you’re burning any fat now!
Turns out, your metabolism is not that complicated. The idea that you have to keep your metabolic furnace stoked with food is a complete myth. Just another example of "experts" trying to make nutrition more complicated then it needs to be.
The portion of your metabolism that is affected by what you eat is very small. The largest part of your metabolic rate is set by your body weight. If you weigh more your metabolism is higher (especially if it's muscle), if you lose weight, your metabolism will go down.
The foods you eat effect your metabolism by something called "the thermic effect of food", which is the energy it takes your body to process the food you eat for storage or use, but again this is very small compared to the amount of energy it takes just to "run" your body.
It makes no difference metabolically whether you eat many small meals or one large meal. What does make a difference is the make up of these meals. Protein, carbs, fats and different ratios of each all have very small effects on the "thermic effect of food" which then has a very small effect on your metabolism.
Bottom line- It's still very important to eat "lean and green" and there are definite benefits to eating smaller meals throughout the day. But if you are looking to your diet as a way to control your metabolism, you're missing the boat.
The best way to increase your metabolism is with exercise. Other than drastic changes in bodyweight, this is the one way you can control your metabolism. Effective weight loss programs like Craig Ballantyne's Turbulence Training program or the ShapeShift program over at grrlAthlete.com are examples of good workout programs that can increase your metabolism.
Remember, if you miss a meal or cut your calories a little too low it doesn't mean you've shut down your metabolism. Your diet is still incredibly important in the fat loss process - (In my opinion it's even more important than your workouts), It’s just not the main regulator of your metabolic rate.

Diet Pop - Do You REALLY Know Enough?
You may or may not know that back in 1990, Diet Orange Crush was recalled in certain areas of the US because it had an elevated Benzene content.
Earlier that same year, there was a recall on Perrier spring water for the same reason.
Now, it's safe to say that benzene was not being added to these drinks on purpose. It turns out that two common ingredients in many drinks - sodium benzoate and ascorbic acid (vitamin C) can react to create benzene.
I'll be the first to admit that when I found this out, I was a little scared. From what I knew about benzene, this sounded like some pretty scary stuff.
You see, Benzene is an organic chemical compound that is used mainly as an industrial solvent and precursor in the production of drugs, plastics, synthetic rubber, and dyes. It's not exactly something I want in my drink.
The US Department of Health and Human Services (DHHS) classifies benzene as a human carcinogen - a compound that promotes cancer.
Eating or drinking foods that contain high levels of benzene can cause vomiting, irritation of the stomach, dizziness, sleepiness, convulsions, rapid heart rate, and death.
So should we throw away our sodas and never touch them again? Well for many health reasons the answer may be yes, but NOT because of the risk of benzene content alone.
Everyone is exposed to a small amount of benzene every day. In fact, auto exhaust and industrial emissions account for about 20% of our total national exposure to benzene. We are also exposed to benzene from both active and passive second hand smoke.
So while we do want to limit the amount of benzene we are exposed to, the contribution from sodas is actually very small.
It is still a good idea to read the label of any soda you wish to purchase. Avoid or limit the consumption of products that contain both ascorbic acid and sodium benzoate.
Other factors that affect the formation of benzene are heat and light. Storing soft drinks in warm conditions speeds up the formation of benzene. Interestingly, sugar has been shown to inhibit the formation of benzene.
So while the small amount of benzene that may or may not be present in your soda is not a reason to panic, it is another reason to drink mostly water or green tea and save the soda pop for special occasions.

Preserving Muscle Mass While Dieting
Back in early August, I wrote about the "secret" to preventing muscle loss while dieting (check it out here).
My point was this- based on the hundreds of measurements I made back when I had access to a body composition lab, I am convinced that if you are lifting weights while you are dieting, you will not lose any muscle.
After writing that post, I started thinking - I wonder if this is still true for VERY low calorie diets.
Turns out it is.
In a study conducted by J.W. Bryner and published in the Journal of the American College of Nutrition, subjects were put on an 800 Calorie per day diet and weight trained 3 times per week. At the end of the study, subjects lost body fat but did not lose ANY muscle mass.
This is really impressive information as the subjects were on an 800 Calorie per day diet for 12 WEEKS!
What's even more significant about this study is that the subjects were only eating 80 grams of protein a day for 12 weeks.
This study helps prove that it was the weight training and not the high protein diets that caused the preservation of muscle mass I talked about in my last post.
Based on this research, and my own research, I am certain that the best way to preserve your muscle mass, even when on an extremely low calorie diet is to weight train.

3 Great Tips from CB
Last week I wrote about the importance of these next several weeks -The time between Halloween and New Year's. These weeks can make or break any physique.
I also asked you to throw out your Halloween candy. If you haven't done it yet, go do it now! (They're two weeks old now, it's time for them to GO)
Now its time to cover the next key to making these ultra-important weeks your best ever, so you can hit the ground running come new years eve.
It drives me crazy to hear about people working really hard in the gym but getting no results.
But I see people in the gym everyday that are doing the same workout and getting no where. You can see the look of frustration and the dread of even doing the workout in their eyes. I hope this doesn't describe you and your fat loss situation. If it does, let's take a look at some of the best fat loss tips and workout solutions to get you back on the fat loss track.
I checked in with my friend over at turbulencetraining.blogspot.com, Craig Ballantyne and had him list his Top 3 Training Tips for Fat Loss...
CB's Top 3 Training Tips for Fat Loss
i) Train with intensity. Yes it takes a lot of effort to do 45 minutes of cardio, but that is low-intensity exercise (since you can do it for 45 minutes straight). Instead, you have to increase the intensity of your efforts. That means the following...
ii) Don't rely on slow, steady, long workouts of cardio. Use intervals instead.
iii) Don't use high reps for fat loss. Use low reps instead. You want to increase the intensity of your training to put "metabolic turbulence" on your muscles. So you need to use moderately heavy weights or advanced bodyweight exercises and interval training to apply this metabolic disturbance and elicit a significant increase in post-exercise energy expenditure.
Bottom line: While long cardio work is focused on breaking down the body, strength training, intervals and bodyweight exercises like yoga and Pilates all focus on building the body. Stick with body-builders.
Sincerely,
BP

Halloween Fat-Bombs
They've been sitting around your house for almost an entire week.
You've used every excuse possible to avoid having to deal with the issue (the latest excuse I heard was that they cost money so you CAN'T throw them out). But now it's time.
Go find your hidden stash of left over Halloween candy and throw it in the garbage! - ALL of it.
You don't need it and what's worse, it is sabotaging you for what could be the most important 8 weeks of the year.
Yes, it's true. There are only 8 weeks left until New Years Eve. It is this gap, between Halloween and New Years, where I see most people put on weight and let go of their fitness goals.
However, if you can do some damage control right now, keep your weight where it is, maybe even lose some fat and gain a little muscle, then you will be miles ahead of everyone else come January first.
Imagine hitting January first in full stride!
It is possible, but first you have to get your nutrition back in order - which means throwing out the candy.
Second, you better get yourself a good new workout program. I suggest you give the grrlathlete Body-Weight Manual a try. It's quick, easy, extremely effective and you can do it at the gym or in your home.
Don't do what everyone else does and hibernate until the New Years...Get started now and avoid the need for a new years resolution!
Helping you make 2007 the best year ever,

Working-Out and Fat Loss
Ever wonder why some people can exercise religiously for months and not lose any weight?
Every now and again I run into this type of woman at the gym. She is on the elliptical everyday at 5:30 AM, and when I'm leaving the gym at 6:30 AM, she's still on the elliptical.
When I'm back in the gym around 7 PM, she's there again too, running through all the weight machines.
The problem is, no matter how hard she pushes herself she's still not losing weight. The answer to her weight loss goals is in her nutrition plan.
To get the best results out of any program you must not only have a great exercise plan, but a great nutrition plan as well.
And a new study has shown us just how important nutrition is for fat loss.
In this study, women exercised on a treadmill until they burned a set number of calories. The women were then asked to guess how many calories they burned during the workout.
The subjects were also told to eat at a buffet and try to eat the same amount of calories that they had just burned during the workout. Think you could do that?
Shockingly, the researchers found that the women over-guessed how many calories they burned by 300 to 400%! And, they ate double to triple the amount of calories that they had actually burned during the exercise!
Are you undoing all the benefits of your workout by eating too much?
Are you giving yourself "free reign" nutritionally just because you worked out?
It's a common myth in the fitness industry that you can eat anything you want after your workout and it won't become fat. It is also a myth that you need large amounts of calories in order to "recover" from your workout (a very small amount will do).
When left to eat as you please, your mind and body will try and convince you to overcompensate and eat more than you normally would.
So don't shoot yourself in the foot and waste all that hard exercise by eating too many calories, especially in your "post workout meal".
Always remember that the best approach to getting the body you want and the performance you desire is by combining a solid exercise program with a sound nutrition plan.

The Two Types of Food
In the last couple of weeks I've been writing about the benefits of interval training for weight loss and athletic conditioning over at grrlathlete.
So now it’s only fitting that I move on to what I consider the most important piece of the puzzle that you need to get in shape, lose weight and improve your fitness - Nutrition.
Nutrition is discussed by just about every magazine writer, talk show host, fitness expert and guru in the industry. Just about everyone and their dog can quote some type of scientific research, touting the benefit of eating one certain type of diet or another, or ramble on about the scientific reasons why some foods are better for you than others.
In my opinion, all of these scientific intellectual ramblings may actually be part of the reason why people still don't eat well.
Let's face it, when it comes to understanding what's good for us and what's not, "science" is confusing the heck out of us!
Because the science of nutrition seems to involve flip-flopping your opinions every other day, the best approach to eating healthy is to look at nutrition with the most simplified technique possible. In your mind think about what your current goals are, whether it is sports performance, weight loss, weight gain or overall health, identify your goals.
Once you have your goals firmly in your head, think of a food, any food.
Now ask yourself "Will this food move me closer to my goals or farther away from my goals?". If you believe it will help you move closer to your goal, then eat it.
If you believe it will actually move you away from your goals, then don't eat it, or at least eat it moderately and in very small portions.
The key to this technique is that you have to believe that there are no "neutral" foods. It is either good or bad.
The trouble with eating healthy is that nobody wants to think about it because nutrition is perceived to be a very complex and confusing topic.
But when we don't think about it, we eat what is put in front of us, and when we eat what is put in front of us, chances are we over eat, and eat the wrong foods.
However, when you simplify the problem down to "good food, bad food" it becomes very easy to "think nutrition". It is not complex or confusing. It simply returns to very fundamental wisdom that your grandmother probably told you when you were a child. Gravitate towards fruits and vegetables and lean protein, and be weary of anything processed (generally foods that you buy in a bag or in a box).
So forget all the debates and all the fads. It doesn't matter whether or not aspartame is good for you. Look at that diet cola and ask yourself if it will move you closer to your goals. If the answer is no, then go get a sparkling water, or green tea or any other drink that you think will move you towards your goals.
By following this principle it makes it easier to "think" nutrition. Every time you put some food in front of you ask the simple question "good or bad" and then act accordingly.
You will find that by simplifying nutrition down to this simple equation you can make dramatic improvements in the way you eat, and avoid a lot of the confusion that is out there.
Nutrition really is the missing piece of the puzzle for any fitness program, and from our experience, when you combine interval training and really good success measurements (like the ones we outlined last week) with a solid nutrition program, amazing things can happen in very little time.
