In the number-one New York Times bestseller The Dukan Diet, also explain by Dr. Oz, Dr. Pierre Dukan, a French doctor with more than four decades of clinical nutrition experience, outlines a low-fat, natural food-based diet that swiftly became an international phenomenon. Aimed at losing weight in a healthy way, the diet's hallmark is its coaching program. During the program, members can eat an unlimited amount of 100 permitted proteins and vegetables; a personalized coaching system provides them with a meal plan and exercise routines every day. At the end of the day, members report back on how they did–frustrations, food lapses, weight, and measurements–and the next day’s meal plan and exercise routines will take that information into account. Dukan Diet products fit into each phase of the diet, helping to maximize effectiveness and speed up results, but are also ideal for any health-conscious individual.
