The Dukan Diet was already a huge bestseller when the British media
reported that Kate Middleton’s mother was following it to prepare for her daughter’s wedding on April 29. Created by French doctor Pierre Dukan, the program is a variation on the Atkins Diet—high-protein, low-fat, and modest carbohydrates—and has many critics who doubt its efficacy. (This being a French plan, there is also a “celebration meal,” which allows for wine and dessert.) When news broke that Carole Middleton was a
Dukanniste, many wondered if Kate herself was on the program, especially since the future Queen is known for her sweet tooth. (Last month, Kate’s favorite candymaker, Haribo, created a
new gummy product in her honor.) So far, the palace has been mum about Kate’s weight, but
The Dukan Diet will be published in the U.S. on April 19.
