One piece of advice often given to dieters is to eat until you reach satiety — that is, until you feel full. The problem is that different foods can have vastly different effects on hunger and satiety. For example, 200 calories of chicken breast may make you feel full, but it could take 500 calories of cake to have the same effect. Thus, weight loss isn't just about eating until you feel full. It's about choosing the right foods that make you feel full for the least amount of calories.
