Do you feel the need to eat more than usual when you exercise?

Resist the urge to eat by drinking a large glass or bottle of PLAIN cold water.. It will fill you up.

Food is energy. Hard work requires more calories naturally.

Not really.

i do but i can't swallow much.

though, w/exertion it is important to maintain proper dietary requirements for you.

(oh, i know, that really helped :P )

principle is simple.

your body is a machine, keep it running smoothly.

Yes
