When I started to exercising and trying to lose weight back in the spring, I was famished. I ate more than I should have, probably. Now that my body is accustomed to exercising more intensely on a regular basis, my appetite has evened out. It may also be that when you're craving food it might actually be something else. Often when I think I'm craving something, I'm actually thirsty--especially if I'm exercising more. Try drinking a glass of water and waiting 10 minutes. It might take care of it--and drinking more water is good for you anyway. Then again, you might, like me, eat the snack you already made anyway.
