A recent study has found that adults with overweight who adopted a low-fat vegan diet consumed fewer calories per gram of food without intentional calorie restriction. The researchers analyzed data from 244 participants in a randomized trial, and found that those assigned to the low-fat vegan diet had a 30% reduction in dietary energy density, or the amount of calories in a given weight of food.
This compared to no change in the control group. The low-fat vegan diet, consisting of fruits, vegetables, grains, and legumes, is high in water and fiber and low in fat, which increases food volume without a proportional increase in energy content. This promotes satiety and reduces energy intake without deliberate caloric restriction.
The study's findings suggest that dietary composition, specifically an emphasis on plant foods, can meaningfully influence energy intake regulation. Clinicians may need to shift their approach to weight-loss advice, encouraging patients to eat differently rather than eat less.
