Volumetrics diet plan is a proven and tested plan that mainly focuses on the energy density of foods taken in. It is more of an eating plan than a diet plan because participants are not prohibited to eat any type of food, but are actually recommended to eat more. The rationale behind this is that a participant can eat more of very low density foods, but must eat limited amounts of high density foods. It primarily focuses on the idea of fullness, which means that foods with higher water and fiber contents are recommended. Many nutritionists suggest this eating plan because it does not focus on deprivation and because of the fact that this diet plan changes the perception of individuals when it comes to food.
