Dispelling nutrition myths, ranting, and occasionally, raving

Have you ever “undone” all your hard work at the gym with a burger? This post is for you.

Have you ever said, or thought, something along the lines of “I cancelled out my workout by eating doughnuts”? How about “I just undid all my work at the gym by having pizza for supper”? Or, “I earned this treat because I ran today”? I’m pretty sure I’ve been guilty of saying those sorts of things. Many of us probably have. For some reason I seem to have become acutely aware of it recently.

I see articles, blog posts, tweets, overheard conversations, where people make statements like those in the examples above all the time. Since it’s the New Year, I expect that a lot of people are making health and fitness related resolutions. I’ve shat all over such resolutions in the past so I won’t do that again today. Instead of resolving to lose weight, exercise more, eat healthier, undergo metamorphosis, perhaps we should consider resolving to shift our mindsets.

The thing is, you’re never cancelling out, undoing, or negating physical activity by eating too much or eating foods that aren’t super healthy. You’re also never earning them by putting in time on the dreadmill. We need to separate the two. Remember when I talked about my problem with many food tracking apps and websites? We often overestimate how many calories we’ve burned during a workout. It’s more than that though. It’s that both exercise and nutrition contribute to our health and well-being but they are both completely separate entities and we need to stop thinking of them as two sides of a scale.

Regardless of what you eat, exercise is still beneficial. Exercise can improve your sleep quality and duration, it can help reduce stress, it’s important for both physical and mental health and can reduce the risk of many diseases. Conversely, regardless of how much you move, a healthy diet is still beneficial. Good nutrition can reduce the risk of many diseases, provide you with energy, can help you recover from injury… Obviously, the two are important contributors to good health. Obviously, you’re going to reap greater benefits if you are both physically active and eat a nutritious diet. However, if you workout and eat a cheeseburger you haven’t then cancelled out your workout. You’ll still be getting some benefits from being active. You’ll still be better off than if you sat on your butt all day and then ate a cheeseburger.

So, stop being so hard on yourself. Stop thinking you’ve failed if you haven’t done an hour of spin and followed that up with a kale salad. Try to separate your thoughts about exercise and your thoughts about nutrition. Your workout happened no matter what you ate afterward. A burger and fries doesn’t erase a swim.

Diabetes management by Huff Post

Ad_for_-Vitamin_Donut-_(FDA_168)_(8212305596)

I found it a little alarming that Huffington Post would publish an article containing medical advice on diabetes management by a naturopath. Not surprising, but alarming.

To be perfectly honest, most of her advice wasn’t terrible (therein lies the worst aspect of naturopathy, it’s often truth laced with completely unscientific bullshit).

Managing carbohydrate intake and cutting back on foods such as white bread can be beneficial. Although, you don’t necessarily have to completely remove all of these foods from your diet and other foods can also lead to spikes in blood sugar.

Getting daily exercise is also great; for anyone, not just someone with type 2 diabetes. Although, touting it as the tool for weight loss is misleading. Most weight loss results from changes in the kitchen, not changes in the gym.

The supplement suggestions make me extremely uncomfortable for several reasons. First of all, naturopaths sell supplements in-house and this is a massive conflict of interest. A medical professional should not profit from the “treatment” they provide to a patient. Secondly, there is insufficient scientific evidence to support supplementation with the remedies she recommends.

The most alarming aspect of this article, in my opinion, is that it’s providing medical advice via a publicly posted article. Treatment of type 2 diabetes (or any other medical condition) should be undertaken with appropriate medical supervision. Without first consulting with your doctor and/or pharmacist there’s no way to know what effect the supplements she recommended might have on an individual. They may be contraindicated for a medication that a person is taking or they may cause other side effects. Even making dietary changes should be done in consultation with your primary healthcare provider. If you’re taking medication for diabetes, making changes to the amount and timing of carbohydrate you’re consuming can affect the way in which your medication works.

If you suspect that you have diabetes, please see your doctor or nurse practitioner for a diagnosis. If you’re currently on medication for diabetes please consult with any/all of the aforementioned medical professionals before making any drastic lifestyle changes and certainly before undergoing any additional supplementation.

Boycott Fit To Fat To Fit

Screen Shot 2016-01-17 at 8.39.35 AM

When I heard about the new TV show Fit 2 Fat 2 Fit I thought “that sounds a lot like that moronic trainer I wrote about years ago.” A little digging through my archives, and it looks like I was right.

For anyone who hasn’t heard about this new show, the premise is a group of personal trainers intentionally gain a bunch of weight (ostensibly so that they “know” what it’s like to be fat) and then they lose the weight again, along with their chosen client.

What I wrote about the original Fit 2 Fat 2 Fit trainer remains true over five years later, and applies to the trainers in the series. Unfortunately, by the sheer existence of a TV series it would seem that his stunt paid off, and then some.

There are so many things wrong with a series like this. Starting with the fact that these trainers are potentially putting their health at risk by gorging themselves to gain weight. And then by losing the weight, presumably through gruelling workouts and restrictive diets. And for what? Money? Fame? Even if they truly believe that “putting themselves in their clients shoes” is helping them to know what it’s like to be overweight, that’s not what this is really about and it’s not providing them with the true experience. They may gain a greater appreciation for how people fat-shame those who are overweight but they haven’t taken the same journey as their clients.

Most people aren’t overweight because they intentionally ate super-sized McDonald’s meals every day. They become overweight for myriad reasons and it happens over extended periods of time, not usually the six months allotted for the TV show. Our environment, our income, our upbringing, our genetics, our friends, our mental health, our gut microbes, our jobs, and on and on, are all factors in determining what we weigh. The trainers involved in the series aren’t experiencing weight gain in the same way that most people do. It’s simplifying a complex issue into calories in, calories out.

In addition to the detriment potentially caused to the trainers themselves there’s the harm potentially caused to their clients (and to the public watching at home). The clients are being taught that they are to blame for their weight gain. They’re also being taught that exercise is the way to lose weight. Have we learned nothing from the Biggest Loser? I guess we have. We’ve learned how to get some great TV ratings. We know that the Biggest Loser can wreak metabolic havoc, not to mention emotional havoc, on the contestants. This is the same thing. Let’s push people to their breaking points so they lose weight we get more viewers. Who cares what happens to them afterwards.

And the harm to people at home? The message the show sends it that it’s your fault that you’re fat and you can lose the weight if you just work hard enough. Even if everyone wanted to destroy their metabolisms at home, most people don’t have the time or money to undertake a punishing daily workout regimen with personal trainers. Nor is there the pressure to make the cut for a TV program looming over our heads. Who has the “luxury” of making weight loss their full-time job? Not to mention the fact that the majority of weight loss is a result of what we eat, not exercise.

Finally, programs like this are teaching us that there is only one way to be beautiful, healthy, loved, and worthy and that’s by being skinny. We all naturally have different body types and what healthy looks like on me may be very different from what healthy looks like on you. Suggesting that everyone needs to have the same abdominal definition to be fit and healthy is the same as suggesting that some of us need to grow a few more inches in height (or become shorter). It’s a ridiculous and impossible ideal.

Please don’t watch this show. By watching, you are only helping to support dangerous attitudes to weight and perpetuating false ideals and helping A&E make money from the suffering of others.

Dr Folta and Dr Blair and the problem with industry funding

A couple of things happened in the scientific world in fairly short succession recently. I spent a lot of time waffling about whether or not I should write about them. Primarily because I don’t want to draw the ire of the pro-GMO community. I see a lot of rabid support for “science” on twitter and I fear being dismissed as anti-science. But this post isn’t about whether or not GMOs are great, or even whether or not they’re safe. It’s not about my opinions on genetic modification nor organic farming. “What is it about?” you ask. It’s about credibility and honesty in scientific research and dissemination of said research.

A few weeks ago the Internets got their collective panties in a twist because some scientists were revealed to have received money from Monsanto. In particular, one scientist received money to pay for his travel expenses in order to enable him to speak at events. Naturally, he was speaking in support of genetic modification, which aligns with Monsanto’s values. I’ve since seen his supporters claim that this information was freely available to anyone who was interested and that he had never failed to disclose his funding sources. I’ve also seen his detractors attribute quotes to him clearly stating that he did not receive money from Monsanto. I don’t know who to believe. It doesn’t really matter who I (or anyone) believes anyway. The important fact of the matter is that he received money from Monsanto to speak at conferences and events.

The following week the news broke that a number of scientists have been receiving funding from Coke (via a nonprofit organization) to support their research and other logistics. That research focusing on the import of exercise in weight management. Once again, the Internet was collectively outraged. Okay, I exaggerate. Nearly everyone I follow on twitter, and much of the mainstream media, were outraged. The researchers shrugged and said: what’s the problem, we’ve never hidden the fact that we received money from Coca Cola and that money had no influence on our research findings. Everyone rolled their eyes and said: um, bias, helllooo. 

Here we have two instances of scientific funding by organizations which have vested interests in the results. Here we have two groups of scientists saying that the funding doesn’t matter and that their findings would be the same no matter where the money was coming from. So, what’s the problem?

The problem is that by accepting financial support from organizations that have a vested interest in the results and the messages from theses scientists creates the perception of bias. Even if these scientists are completely impartial, and that’s being incredibly generous given the fact that the majority of industry funded research findings support the interests of the funders, it raises doubts about that impartiality. At worst, the scientists receiving the funding have a conflict of interest. At best, they have a perceived conflict of interest, and perception matters. It also makes for an uneven scientific playing field. If all of the players on one team are having their expenses covered by a benefactor then how can the other team hope to succeed. Even if they are better players, they can’t afford to go to out-of-town matches or find the time for extra practice.

If only the scientists with the pro-GMO message or the scientists with the pro-exercise message are given the platforms to share those messages how can we ever hope to find out the truth?

Why I hate the caloric math game

IMG_3246

I have a beef with a lot of the all-in-one fitness/weight management apps. Many people benefit from tracking their calories when they’re trying to lose weight. I’m all for that. What I hate is the inclusion of calories burnt through exercise. I think that a lot of these apps over-estimate the number of calories expended during various activities. This can mean that if you’re looking at the bottom-line to determine how many calories you can eat without gaining weight you’re probably going to eat more than you need. I often tell people to either not track their exercise using these apps or to ignore the additional calories the app then tells them that they can have. Just use the nutrition side of the app. It’s wise to remember that even that’s not going to be 100% accurate, especially if you’re not weighing everything you eat. It’s just another weight management tool in a box of many.

Now for the real beef: I don’t like that these apps try to turn weight loss into a math problem. It’s not. We used to believe that cutting 3500 kcal would result in a pound of weight lost. We now know that it’s much more complicated than that. There are many factors contributing to the weight we are. Yes, how many calories we consume (and expend) are a huge factor in determining how much we weigh, and whether we lose, gain, or maintain our weight. I don’t want to diminish that fact. I’m not going to tell you that if you just ate cleaner you would lose weight. The cleanliness of your calories doesn’t matter when it comes to weight loss. However, adding 350 calories by going for a walk is an oversimplification. It may also lead to an unhealthy way of thinking about food, exercise, and weight management.

Most of us easily consume more calories than we’ve burnt after a workout. Exercise makes you hungry and it’s a whole lot easier to eat 500 calories than it is to expend them during a workout. When we start thinking about exercise as a way to “earn” more calories we’re moving away from healthy eating and healthy fitness. While I’ve said that the cleanliness of your calories doesn’t matter for weight loss, and I’ve also said that there should be no forbidden foods, eating primarily nutrient-rich whole foods is important for your health. A session at the gym shouldn’t be a licence to eat high-calorie, low-nutrient foods for the rest of the day. Focus on gaining health through the food you eat and the physical activity you do, rather than the numbers in an app or on a scale.
