A recent study published in Frontiers in Nutrition suggests that a low-fat vegan diet may be more effective in reducing dietary advanced glycation end-products (AGEs) and promoting weight loss compared to a Mediterranean diet. AGEs are harmful compounds linked to insulin resistance and metabolic health issues that are commonly found in animal-derived foods. The study was a secondary analysis of a trial conducted by the Physicians Committee for Responsible Medicine in 2019, which compared the effects of the two diets on weight loss and cardiometabolic health outcomes.
The results of the study showed that participants following a low-fat vegan diet had a significant reduction in dietary AGEs and body weight, while those on the Mediterranean diet experienced no significant changes. The low-fat vegan diet focused on plant-based foods and excluded animal products and added fats, resulting in a 73% reduction in AGEs and an average weight loss of 13 pounds. On the other hand, the Mediterranean diet emphasized fruits, vegetables, legumes, and fish, but did not show any changes in AGE levels or body weight.
The study participants were a health-conscious group with a relatively low intake of saturated fat to begin with, which could explain the lack of results from the Mediterranean diet. The researchers noted that further research is needed to confirm the findings and determine the long-term effectiveness of a low-fat vegan diet compared to a Mediterranean diet. However, previous studies have also reported reductions in dietary AGEs with a low-fat vegan diet in adults with overweight and individuals in postmenopause.
AGEs are compounds that form in the bloodstream through glycation reactions and can also originate from food sources. Animal products, cooked at high temperatures, are known to be high in AGEs, while plant-based foods typically have lower levels. Reducing dietary AGEs, particularly through adopting a low-fat vegan diet, can help promote weight loss by improving insulin resistance, decreasing inflammation, and enhancing overall metabolism.
Experts recommend a gradual approach to adopting a low-fat vegan diet, including incorporating more plant-based meals into your routine and seeking guidance from a doctor or registered dietitian to ensure balanced nutrition. This may involve including a variety of fruits, vegetables, beans, nuts, seeds, grains, and soy products while limiting processed foods and supplementing with essential nutrients like vitamin B12. Whether or not a vegan diet is right for you, reducing consumption of animal-based foods and increasing intake of plant-based foods can have beneficial effects on health and weight management.
