Other: Drink more water! Apparantly a lot of times we feel hungry they are actually thirsty, and we don't know the difference. So have a glass water first, and if you're still hungry, then have a snack. Most of us don't drink enough water anyway. I know I have this problem.
Well, when my tummy is growling... I know it's from lack of food... but a huge glass of water fills it up and makes it stop growling.
