pro-tip: the reasons doctors don't say what i'm saying is not because they disagree (they know i'm right...), but because they don't think
it will work. they're convinced that north americans are hopeless, fat
slobs with irreversibly sedentary lifestyles, and they'll never get
anywhere telling them to decrease their total intake. so, they just give up on them and try and tweak their diets, instead.
when your doctor tells you to change your diet, this is harm reduction. the actual solution is to modify your energy intake to be more in line with your energy expenditure so that you aren't storing fuel for later, and then internally imploding like the scene from se7en.
