I really appreciate the great answers here! I think it is very difficult for someone who has never been more than a little overweight to understand how it feels to live with real obesity. It must be a very real challenge if one has a type of addiction to have to face that addiction several times a day. There's no way of just avoiding food.
We all are hardwired to some extent to eat when there's food available, and to enjoy calorie-rich foods. But most of us who cycle also know the joy of movement, of getting fitter, of feeling your body work well the way it's supposed to. And everybody knows the actual physics of "burn more, eat less". On paper it's so simple. In real life it's obviously hard, otherwise we wouldn't be spending masses of time and money talking about it and inventing strange diets. But I'm also convinced that it's very much harder for some people, whether it's genes, psychology, habits, culture, metabolism or whatever. Willpower can get you only so far for a certain amount of time, after that a lot more things have to be in place to get you through.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
