Devised by Dr. Pierre Dukan, a French medical doctor who has spent his career helping people to lose weight, the Dukan Diet rejects counting calories and promises permanent weight loss while allowing adherents to eat as much as they like. Originally published in 2000, the Dukan Diet swept across France, championed by people who successfully lost weight following its unique four phase regime. The Dukan Diet has helped millions in France, where it has been number one for more than ten years and adopted in twenty countries, including the United Kingdom, Poland, Korea and Brazil. All together, The Dukan Diet has sold more than 3 million copies worldwide.
