The Dukan Diet: What It Is

It's been a best-seller in France for years, but now The Dukan Diet is getting attention on this side of the pond. It's no wonder: The book claims to have helped 5 million French people lose weight. And singer Jennifer Lopez and model Giselle Bundchen are reported to have lost their post-pregnancy pounds on The Dukan Diet.

The Dukan Diet was created by French physician Pierre Dukan more than 10 years ago as a treatment for obese people.

Essentially, it's a four-phase, high-protein, low-calorie diet plan. There's no weighing foods or counting calories. You eat as much as you want, at any time of day -- as long as what you're eating is lean protein, at least initially.

In fact, protein is the centerpiece in all four phases, along with oat bran, lots of water, and a 20-minute daily walk. Vegetables are allowed in the second stage, followed by small amounts of fruit and whole grains.
