DOES YOUR FOOD MAKE YOU GAIN WEIGHT?

If you associate dieting with hunger or are just concerned that cutting back on your eating would leave you feeling unsatisfied, you shouldn't worry because calories don't count in satisfying your hunger. The amount of food you eat will determine whether you are hungry or satisfied regardless of the caloric content of the food that you're eating. In other words, you can be more satisfied and lose weight by eating larger portions of less dense (fewer calories for the same size portion) foods instead of a smaller portion of more dense food. If you've found that dieting always leaves you feeling hungry, eating less dense foods can help you lose weight without this discomfort.
