Starting your meal with a bowl of soup, apple or a salad will help you to lose weight

Eating soup, apple or a salad as a first course helped study participants lose weight because they consumed fewer total calories in the rest of the meal.

Dr. Barbara Rolls, a weight control researcher at Pennsylvania State University and author of "The Volumetrics Eating Plan," found that eating soup as a first course helped study participants lose weight because they consumed fewer total calories in the rest of the meal.

Rolls' theory is that the more water a food contains the more full we feel. And the lower the energy density of a food (the concentration of fat and calories) the more we can eat.
