Doctor Pierre Dukan gained public praise for his weight-loss regime when Kate’s mother Carole Middleton allegedly tried the diet before the royal wedding. The French doctor — with 35 years of clinical nutrition experience — has released his second book about the diet, The Dukan Diet Cookbook (2012 Random House Canada). Already popular over in Europe, the cookbook offers more than 350 simple, easy-to-follow recipes. Dukan empowers readers to achieve their weight-loss goals while still enjoying delicious food.
