Unlike other diets, the Volumetrics diet does not limit the amount of food consumed. Severe food limitation does not result in long-term weight loss, according to Barbara Rolls, nutritionist and creator of the Volumetrics diet.
Dieters who limit their food intake will always hungry, unsatisfied, and most likely will come back to old eating habits. The crux of the Volumetrics diet is that it includes foods that offer the sense of satiety. There are no good of bad foods, according to Rolls. She thinks that foods must be divided into four categories according to their energy density.
The energy density refers to the number of calories found in a certain amount of product.
If you consume foods with high energy density, you will probably gain weight. However, if you consume foods with low levels of energy density, you may eat more and feel fuller.
The first of the four categories includes foods with very low levels of energy density, such as vegetables without / poor in starch, fat-free dairy products, and tomato soups.
The second category includes foods with low levels of energy density, such as fruits and vegetables, cereals, or pasta.
The third category includes cheese, pizza, salads with chicken meat and dressings, and ice cream.
The foods with high energy density include biscuits, chips, chocolate, candies, butter, peanuts, and oils.
The Volumetric diet's author recommends high fiber products and healthy fats from fish. Sweets, fats, and alcohol are allowed, but they should be consumed in moderate amounts.
