I read Good Calories, Bad Calories and I greatly enjoyed. Although I am in no position to judge the validity of everything he says, I found it very compelling in several areas.
My favorite section was on obesity since it totally changed the way I look at overweight and obese individuals. I've just never really considered the idea that the energy balance equation was a tautology and sheds no light on the obesity epidemic. I always considered it to be obvious that a positive caloric balance was the problem and that this was caused by a self indulgent indolent society.
Why am I not fat (6'4, 205)? I exercise and eat in moderation, I would say. But the more I thought about the more I realized that my weight has stayed the same for about 7 years now and there is no way that fact is the result of me consciously regulating my input/output. I never even tried, so if it is something that is regulated consciously I have gotten extremely lucky. My guess is its not just about input/output.
Anyway, Taubes caused a great paradigm shift in my thinking and I'd like to know what others think about his arguments about obesity. Here is a link to a lecture he gave about the subject:
