Bonnie - this is already a "been there done that diet". It is not exactly news that if we ate similar to our paleolithic ancestors, we would not be in the throes of an obesity epidemic. The Dukan Diet simply adds gimmick or two to separate itself from the hundreds of others that have come and gone.
The Dukan method proposes a healthy eating plan that returns to the foods which founded the human species, those eaten by primitive man, the hunter-gatherers, proteins and vegetables, 100 foods including 72 from the animal world and 28 from the plant world. This offer also features the magic words: As Much As You Like.
While some of the core principles I do agree with, I still consider this a fad diet, because it is promoting short-term weight loss, with no concern for long-term weight maintenance, is not geared towards the individual, and is not sustainable.
