Finally—the ultimate diet for fast, safe weight loss, lifelong health, and longer life, based on more than twenty years of research and the latest findings on appetite and weight. Metabolic specialist Ron Rosedale, M.D., has designed the Rosedale Diet to regulate the powerful hormone leptin, which controls appetite and weight loss by telling the brain when to eat, how much to eat—and when to stop. New research shows that leptin may be one of the body's most important hunger control mechanisms. Control leptin, and you control your weight.
