The Mediterranean diet, which has conquered the world with its flavours and its health benefits, could now be dethroned by the vegan diet, which may be more effective for weight loss and cholesterol control, new research suggests.
Forget olive oil, fragrant herbs and stuffed vegetables, the Mediterranean diet could soon be overtaken by the vegan diet. While the diets aren't that far removed from one another, the vegan regime could be a better option for weight loss, controlling cholesterol and insulin sensitivity, according to a new study from the Physicians Committee for Responsible Medicine.
To come to these conclusions, the scientists selected participants who were overweight and had no history of diabetes, and randomly assigned them a vegan or a Mediterranean diet. Half of the volunteers started with a low-fat vegan diet excluding animal products and focusing on fruit, vegetables, whole grains and legumes. The second group started with a Mediterranean diet focusing on fruit, vegetables, legumes, fish, low-fat dairy and extra virgin olive oil while limiting or avoiding red meat and saturated fats.
Participants' calorie intakes were not limited, and they did not change their exercise or medication regimes unless otherwise directed by their personal doctors. Participants followed each diet for a period of 16 weeks, then went back to their regular diets for a four-week "reset" before switching to the opposite group to follow the other diet for an additional 16 weeks.
