The Volumetrics Diet is a scientifically grounded eating plan designed to promote weight loss and long-term health. Created by nutrition scientist Dr. Barbara Rolls in 2000, this diet emphasizes eating large volumes of low-calorie, nutrient-dense foods to feel full while consuming fewer calories. Unlike many fad diets, Volumetrics is a sustainable lifestyle change that has earned the respect of healthcare professionals worldwide.
The Core Principles of the Volumetrics Diet
The foundation of the Volumetrics Diet lies in prioritizing the volume of food over calorie count. No food is entirely off-limits, but the focus is on consuming more foods with low-calorie density and fewer high-calorie foods.
Food Categories in the Volumetrics Diet
Foods are divided into four categories based on their calorie density, which is calculated by dividing the calories per serving by the food’s weight in grams.
Category One (Calorie Density Under 0.6)
These are the most nutrient-dense and low-calorie foods that form the bulk of your diet.
Examples:
- Fruits: Apples, bananas, grapefruit.
- Non-starchy vegetables: Broccoli, carrots, Brussels sprouts.
- Nonfat dairy: Skim milk, nonfat yogurt.
- Broth-based soups.
Category Two (Calorie Density 0.7–1.5)
These foods are healthy in moderation.
Examples:
- Lean proteins: Skinless chicken, turkey, lean pork.
- Legumes: Lentils, chickpeas, beans.
- Starchy vegetables: Corn, potatoes, squash.
- Whole grains: Brown rice, quinoa, farro.
Category Three (Calorie Density 1.6–3.9)
Consume these foods in smaller portions.
Examples:
- Fatty proteins: Salmon, beef, skin-on poultry.
- Full-fat dairy: Cheese, ice cream, whole milk.
- Refined carbohydrates: White bread, pasta, white rice.
Category Four (Calorie Density 4–9)
High-calorie foods to eat sparingly.
Examples:
- Nuts and seeds.
- Oils, butter, shortening.
- Processed foods: Chips, candy, fast food.
Exercise Recommendations
The Volumetrics Diet encourages 30–60 minutes of daily physical activity, which can include walking, jogging, or other forms of moderate exercise.
