Pierre Dukan is a French former nutritionist, and the creator of a popular diet named after him, the Dukan Diet. Born in 1941 (age 82)

In July 2011 a French court ruled against Dukan in his attempt to sue rival nutritionist Jean-Michel Cohen for libel, after Cohen had criticised Dukan's method in the press.^{[citation needed]}

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.^[1]

In March 2012 the French Ordre des médecins asserted that Dukan had violated the organization's medical code of practice by practising medicine as a business.^[2]

In May 2012, he was removed from the membership of the Ordre des Médecins at his request.^[3]

In January 2014, Dukan was struck off the medical register for promoting his diet commercially.^[4]
