Except that the more you exercise, the more your body hungers for more calories. The homeostasis theory of the body makes far more sense than the current thermodynamic view of eating; that change in weight is equal to what you eat minus what you burn.

If you exercise more, you burn more of course. Supposing that your body has no idea how much energy its consuming, and thus the 'what you eat' part of the equation is independent of the 'what you burn' is simply ridiculous.

Those diseases, the diseases of western civilization wont go away by simply exercising more. Exercise more, you eat more, you don't lose your fat weight, you won't reverse those diseases.

Except that carefully controlled studies have failed to support your claim that sufficient (whatever that is) exercise can reverse or minimize most of those diseases.
