Common Diet Plans for Weight Loss

The Volumetrics diet was developed by a Penn State nutrition professor, Barbara Rolls, as an approach to eating differently. Her theory was that people tend to eat the same amount of food per day — regardless of the calories they contain. Some foods are more energy-dense than others, meaning some foods contain more calories per gram. For example, one pound of carrots would be “low-density” and equal to one ounce of “high-density” peanuts. Rolls believes that, by eating the same amount of food, but making lower-density, healthier choices, weight loss is achievable. Foods that are low-density, like fruits, vegetables, lean meats, soup and whole grains make up the bulk of this diet. High-density foods are considered treats. The Volumetrics diet plan keeps you feeling full, as you are eating the same amount of food. Other than grocery costs, the only cost tied to this diet is the recommended book. While this diet is backed by professional research, talk to your doctor before making any changes to your diet.
