The Dukan Diet is one of the most popular diet plans in France. It is a protein-based diet designed by French nutritionist and dietician, Pierre Dukan. Although Dukan has been promoting his diet for over 30 years, its popularity has grown since 2000. His book The Dukan Diet is a best seller in France while selling more than 10 million copies globally. The book has since been translated into 14 languages and published in 32 countries. The Dukan Diet was released in the UK in May 2010, and in the US in April 2011.
As with some other diet plans, Dukan has launched an online coaching service, as well as online shops.
