Dukan Diet based on ‘coprological studies’ (undigested calories in feces)

The scientific evidence behind Pierre Dukan’s fashionable diet is slim-to-none. Dr. Dukan’s dietary beliefs and recommendations are based on i) anecdotal evidence (see Baloney Detection Kit) and trial-and-error observations in his clinical practice and ii) “market validation” from sales figures of his book.

In 2007 The Dukan Diet was second only to Harry Potter on Amazon France and also sold well in Bulgaria and Poland.

We could not find any publications by Dukan or about his diet among the ~20 million biomedical research articles indexed by the U.S. National Library of Medicine. The only research studies referred to in Dukan’s book are “coprological studies” comparing the calorie contents of stools from individuals who have or have not eaten oat bran.
