A diet that has been floated about in the USA since February 2008, but has been available in Canada for 10 years and in Europe for 20 years is called the "Ideal Protein Diet." It was developed by a French doctor, Dr Tran Tien Chanh, initially intended for French Olympic athletes, allowing them to drop weight quickly.

There are two phases to this diet. The first phase is an Induction phase, where carbohydrates are limited to a tiny amount a day. Three pre-packaged protein meals are used daily, as well as additional protein of your choice. It lasts until 90% of your weight loss is achieved.

The second phase (a minimum of two weeks or until all weight loss goal is achieved) allows a pre-packaged protein meal to be replaced with one of your choice. Carbs are still severely limited. Phase three allows a 14 day gradual re-indroduction of healthy carbs and fats in the morning only. Learn more about ideal protein diet

Sounds a lot like Atkins which has been around for nearly 40 yrs.
