I was curious..we all know that during cardio exercise the body breaks down a certain amount of muscle tissue to use as energy...My question is, if I consume a large portion of carbs right before (maybe hour and a half to two hours) running for an hour (like a good sized cheat meal, some pizza and an alcoholic beverage or two) does my body burn less muscle than it would have seeing as how it has that large stash of carbs to convert into energy?
