Satiety is the fullness you feel after a meal. Satiety is important as it affects how frequently and how much you eat. Understanding satiety and the satiety levels offered by different foods will help you reach and maintain a healthy body shape.
If we don't understand satiety and just try to restrict our food intake, we'll find that we spend much of the time being hungry - and life should be better than that!
By gaining a better understanding of satiety we will be able to eat in such a way that hunger between meals is reduced - and we won't be tempted to go for an off-piste snack!
