Lemon SplashWater does curb appetite, but only if it is incorporated into food, not drunk from a glass. Several studies from Pennsylvania State University found that only water in soups, thick beverages like V8 juice, and other liquid foods fills us up. In one study, women were given a snack of chicken rice casserole with a glass of water or a chicken rice soup that contained the same amount of water as broth. Results showed that the soup was more filling even though it contained 27% fewer calories than the casserole. The reason why water bound to food is filling, while a glass of water is not, is unclear, but it could be that the bound water slows digestion, whereas a glass of water just passes right through.       Photo credit: Muhammad Ahmed via Compfight
