Soup may be the perfect pre-dinner snack. Penn State University researchers discovered that it’s a great appetite suppressant thanks to its winning combo of liquids and solids. In the study, women who had about 270 calories of chicken and rice soup consumed an average of 100 fewer calories at their next meal. But don’t reach for just any soup: Watch out for bloat-inducing sodium, high-cal cream, and carb-loaded pasta and potatoes that may fill you up and out.
