The Dukan Diet argues that calorie-counting doesn’t help people lose weight; instead, eating plenty of protein helps. French general practitioner Dr. Pierre Dukan published a book about the program in 2000, and it quickly became a bestseller. On the diet, people aim to achieve their “true weight” (or goal weight) through four phases of eating plans.
