Feb. 5, 2021 (MedicalXpress) -- A vegan diet is more effective for weight loss than a Mediterranean diet, a groundbreaking new study shows.
The randomized crossover trial, which was published in the Journal of the American College of Nutrition, found that a low-fat vegan diet has better outcomes for weight, body composition, insulin sensitivity, and cholesterol levels, compared with a Mediterranean diet.
The study found that within 16 weeks on each diet:
Participants lost an average of 6 kilograms (or about 13 pounds) on the vegan diet, compared with no mean change on the Mediterranean diet.
Participants lost 3.4 kg (about 7.5 pounds) more fat mass on the vegan diet.
Participants saw a greater reduction in visceral fat by 315 cm3 on the vegan diet.
The vegan diet decreased total and LDL cholesterol levels by 18.7 mg/dL and 15.3 mg/dL, respectively, while there were no significant cholesterol changes on the Mediterranean diet.
Blood pressure decreased on both diets, but more on the Mediterranean diet (6.0 mm Hg, compared to 3.2 mmHg on the vegan diet).
