New Research Suggests a Low-Fat Vegan Diet May Be More Effective for Weight Loss Than the Mediterranean Diet, Despite Including "Unhealthy" Foods.
A recent study has found that a low-fat vegan diet may be more effective for weight loss than the traditional Mediterranean diet, despite including some so-called "unhealthy" foods like refined grains and potatoes. The research suggests that even when plant-based diets include less-than-ideal foods, they can still lead to better outcomes for insulin sensitivity, cholesterol levels, and body composition.
In the study, 62 overweight adults were randomly assigned to follow one of two diets: a Mediterranean diet featuring fruits, vegetables, legumes, fish, low-fat dairy, and extra-virgin olive oil, or a low-fat vegan diet consisting of fruits, vegetables, grains, beans, and other plant-based foods. The participants took turns following each diet for 16 weeks, with a four-week break in between.
By the end of the study, researchers found that the vegan diet was more effective for weight loss than the Mediterranean approach, despite including some "unhealthy" foods like refined grains and potatoes. The vegan diet also led to better outcomes for insulin sensitivity and cholesterol levels, as well as more favorable changes in body composition.
So, what makes a plant-based diet so effective? According to the researchers, many plant-based foods are high in fiber and have a low energy density, meaning they contain fewer calories per gram. This allows you to eat larger, more satisfying portions without consuming excess calories, which can support weight loss.
For example, most vegetables are very low in calories, so you can enjoy a big plate and still stay within your calorie goals. In contrast, nuts and oils have a high energy density, meaning even small portions contain many calories and can make it easier to overeat.
The researchers also reported that many foods in the vegan diet can stimulate the body's production of glucagon-like peptide-1 (GLP-1), a hormone that triggers insulin release from the pancreas, slows digestion, and signals to the brain that you are full. This is similar to how weight-loss drugs like Ozempic and Wegovy work.
Overall, the study suggests that even when plant-based diets include some "unhealthy" foods, they can still lead to better outcomes for weight loss and overall health.
