A Vegan Diet Proves Most Effective for Weight Loss
A vegan diet leads to the most weight loss, compared with other dietary patterns, according to a new study in the journal Nutrition. Sixty-three overweight adult study participants were assigned to one of five different dietary patterns for a six-month period: omnivorous, semi-vegetarian, pesco-vegetarian, lacto-ovo vegetarian, and vegan. At the end of the study, the vegan group lost, on average, more than twice the percentage of body weight (7.5 percent), compared with omnivores (3.1 percent), semi-vegetarians (3.2 percent), and pesco-vegetarians (3.2 percent). The lacto-ovo vegetarian group lost an average of 6.3 percentage points. The vegan group also had the greatest reductions in total fat, saturated fat, and cholesterol and greatest increase in dietary fiber intake—all protective against chronic diseases such as heart disease and diabetes.
