Why Your Personal Trainer is Full of it – and what you can do about it

If you’ve been to the gym in the last 10 years you’ve undoubtedly seen countless patrons slaving away doing hundreds of crunches, triceps kickbacks, and as many different “thigh sculpting” contortions as you can think of, possibly all while standing on a Bosu ball on top of a balance board while strapped to the wall by elastic bands. In my experience most of these strange permutations of exercise are inspired by someone’s personal trainer/fitness trainer/health and wellness coach or by an article published in any random men’s health or fitness magazine written by one of the aforementioned “fitness experts”. They throw around terms like “functional fitness” and “core strength” and my favorite… “toning”. Of course these guys must know what they’re talking about… look at them – they’re ripped!

There are many die-hard fans out there of nearly every type of diet out there, but many of the most popular diets all have one thing in common: they are centered around manipulating the ratios of the macro-nutrients (a term that is not wholly useful in light of our current understanding of biochemistry, but that we’ll save for a later post), namely, carbohydrates, fats, and protein. Protein is necessary for life. A diet far too low or far too high in protein is incompatible with any organism surviving for very long. This leaves us with the option of manipulating the amount of carbohydrates and fats in the diet. Expert opinions abound where randomized control trials lack. I’ve compiled a small literature review using some of the best sources available to me to help determine whether low carbohydrate diets are better than high carbohydrate diets in the long term for the reduction and long term maintenance of body fat while taking into account general markers for health like mortality from heart attacks, stroke, or other diseases.
