The Dr Dukan diet has been credited with helping the Duchess of Cambridge fit into her wedding dress in 2011.
Kate Middleton's mum Carole and her sister Pippa are also said to have tried and tested the diet, as well as Jennifer Lopez, Penelope Cruz, Gisele Bundchen and Welsh opera singer Katherine Jenkins.
The diet works on the premise of controlling the number of fat cells (adipocytes) in the body, and is based on eating different foods in 'phases' – always low in fat.
With the sun set to shine this Bank Holiday weekend, try these tasty recipes – spicy chicken kebabs, Asian-style beef skewers, a succulent burger and even chocolate ice cream – for a low-fat take on British favourites.
