Researchers at Loma Linda University found vegans had the lowest average BMI of the study population, while meat-eaters showed the highest average BMI and highest intake of heart disease-related fatty acids. Participants in the vegan arm also had the lowest number of obese individuals at 9.4%, compared with 33.3% of meat-eaters, researchers reported. Caloric intake was similar across the groups, but there were differences in the type of nutrients consumed.
