Changes in Food and Nutrient Intake and Diet Quality on a Low-Fat Vegan Diet Are Associated with Changes in Body Weight, Body Composition, and Insulin Sensitivity in Overweight Adults: A Randomized Clinical Trial

Healthy plant-based diets improve dyslipidemias, insulin resistance, and inflammation in metabolic syndrome. A narrative review

“…This beneficial effect may be due to the presence of the phytonutrients of plant origin and the absence of animal fats, in addition to the increased consumption of low glycemic index foods. Data from a randomized controlled clinical trial in overweight adults suggest that increasing low-fat plant foods and minimizing high-fat and animal foods are associated with decreased body weight and fat loss and that a low-fat vegan diet can improve measures of diet quality and metabolic health [ 27 ]. Different protein concentrations fed to mice were used to determine improvement in MetS parameters [ 28 ].…”

The Ethics of Veganism

“…Reducing the likelihood of chronic diseases: According to a 2019 review by the American Heart Association and published in their journal, the Journal of the American Heart Association, one can lower their chance of developing coronary heart disease, diabetes, and numerous types of cancer by adopting a vegan diet [30][31][32][33][34]. Lower BMI: A study that appeared in the Journal of Inner Medicine claimed that those who follow a vegetarian diet have a lower body weight and BMI than people who follow a non-vegetarian diet [35,36]. Increased nutrient intake: A larger intake of vegetables, fruits, grains, and seeds, which are all rich in minerals, vitamins, and fibers, is typical of vegan diets [37].…”

Plant-Based Diets and Metabolic Syndrome Components: The Questions That Still Need to Be Answered—A Narrative Review

“…A study by Crosby et al [ 67 ] showed statistically significant improvements in anthropometric and biochemical parameters exhibited by the low-fat vegan intervention group compared to the control. It should be noted that participants in the control group were not required to follow any dietary recommendations and did not receive standard medical care.…”

“…Another major problem is the heterogeneity of the studies in question, with variability already being present in the control groups. In some cases, the control groups followed country-specific dietary recommendations [ 40 , 65 , 66 ], while in other studies no nutritional guidelines were provided [ 40 , 64 , 67 ]. A better approach would be for the control group to follow an optimal dietary model developed for the country or at least to adhere to general world recommendations [ 69 ].…”
