The volumetrics diet is based on the idea that the volume of food you eat, rather the counting calories, leads to weight loss. When more food is consumed, you experience a fullness in a psychological sense. The diet follows more of an unstructured eating approach than one that restricts specific foods and severely limits your daily caloric intake.
What Experts Say
"The premise of this diet is simple—eat lots of high-water-volume foods to help fill you up and shed pounds. Nutrition experts agree this is a smart choice, as you’ll increase nutrient-dense choices like vegetables and fruits while naturally consuming fewer calories."
The 7-Day Diet Plan
The volumetrics diet does not require meal timing or portion sizes. Rather, no food is off limits in the diet, but it does focus on a food’s energy density. Food that is high in calories but contains limited vitamins and minerals is considered high-energy-dense.
Meanwhile, food with a low amount of calories that offers a high number of vitamins and minerals is considered low-energy-dense, and should make up the bulk of what you eat.(U.S. News and World Report Best Diets Overall 2022.)

Group two:Low-density foods, such as grains, unprocessed meats, legumes, fruits, and vegetables.
Group three:Medium-density foods, which should get eaten in small servings. These foods are refined carbohydrates and high in fat and sugar, such as meat, cheeses, French fries, ice cream, and baked goods.
Group four:High-density foods that should get consumed only every once in a while. These foods are higher in fat and carbs than group three foods, which include butter, nuts, crackers, candy, oil, and cookies.
Pros of the Volumetrics Diet
As one of the top-ranked diets for overall weight loss and healthy eating, you'll find significant advantages to following the volumetrics diet.
Provides Long-Term Healthy Eating:Recent peer-reviewed research demonstrated that dietary management using principles found in the volumetrics diet can help people not only lose weight, but obtain an eating pattern that they can sustain indefinitely.
