Ive always been under the impression that you need a slow release protein to feed your body as in repairs itself while you sleep. But ive got a mate whos fitness mad, does judo, badminton etc, has a very healthy and varied diet, and says that in order to be healthy, you shouldnt eat carbs after 6pm and you should have nothing but water after 8pm as your body wont you it and it will just turn to fat. A close friend of hers is a bodybuilder and apparently 'wet himself laughing' at the fact I was eating cottage cheese before bed as the body has nothing to do with it while you sleep so its going to fester and turn to fat.
