Vegetables are a major component of the Fuhrman Diet. Dr. Joel Fuhrman is the creator of the Fuhrman Diet, more often referred to as the Eat to Live Diet. The Fuhrman Diet is a vegetarian weight-loss plan that promises participants that they can lose up to 20 pounds within the first six weeks on the diet. While certain foods are completely off limits on the Fuhrman Diet, other foods are only allowed in small portions.
