Volumetrics has been named the #1 diet, according to Consumer Reports. Ever hear of it? The weight loss principle behind the diet plan is the least amount of calories per maximum amount of volume. (Think foods that have high water content, like fruits, vegetables and soups).
Like most newer diet plans, the idea is to not cut out all the foods you like, but to control the portions, frequency of eating, and place an emphasis on natural and whole grain foods.
