Every year, Diets in Review.com looks at the most popular diets from the past year. This year, the winner is the Ideal Protein Diet, which we proudly offer at Evolution Body Transformation! The Ideal Protein Diet moved up 13 spots to grab the number one spot as 2015’s most popular diet. Ideal Protein surpassed many of the past popular diets on the market, such as Medifast and Weight Watchers. In fact, this is the first year that Weight Watchers dropped out of the top five.
