If you don't mind the taste of cellary, you can always eat that during meals or for a snack. it has negative callories- you burn callories just by eating it. green tea can be a apitite suppresant, if you have trouble with cravng things. And COLD water burns callories. it has no callories in it, so when your body heats up the water, you burn callories. ... what else... I heard that sucking - not chewing- on an ice cub can burn up to 100 callories(depending on the size), and I know it burns some callories, but I'm not so sure if it's actually that many. hope that helps!! good luck
