In 1975, Pierre Dukan is a general practitioner in Paris when he was first confronted with a case of obesity. At the time, being overweight or obese was thought to be best treated by low calorie and small sized meals. Dukan thought of an alternative way to prevent patients from regaining their lost weight after dieting. He designed a new approach in four phases, including stabilisation and consolidation. After 20 odd years of research Pierre Dukan published his findings in 2000 in his book Je ne sais pas maigrir (I don't know how to get slimmer) which became a bestseller in France.
The book became a bestseller in the UK after Carole Middleton introduced her daughter Catherine, now The Duchess of Cambridge, to the diet before her wedding to Prince William. Catherine lost two dress sizes.
In January 2012, Dukan suggested that the Baccalaureate exam, taken by 17-year-old children, should include one test which the children could pass simply by staying within appropriate weight limits. He faced a disciplinary hearing in connection with these remarks.
In January 2014, Dukan was struck off the medical register for promoting his diet commercially.
