The more plant-based diets also led to more favorable changes in
macronutrients, fiber, and cholesterol, particularly among the
vegan diet group. The findings point to a potential use of plantbased
eating styles in the prevention and treatment of obesity
and related chronic diseases. The weight loss results of the
present study going from greatest weight loss among the vegan
group to the least in the omni group mirror the direction of
other health-related outcomes observed in several large nonrandomized
prospective cohort studies, including metabolic
syndrome [32], cancer incidence [33], type 2 diabetes [4], and
all-cause mortality
