Any breakfasts, not only the ones rich in carbohydrates, quickly reverse the picture: glucose rises and ketones fall. For the lucky ones among us that is more or less OK, but for many of us it is not good -- because of the insulin resistance or exaggerated response to the taste of any food, or for some other reasons. The fact is, skipping breakfast does wonders in many tough cases of stalled weight loss.
There are at least two famous health systems known to me that employed this principle: one of them is Paul Bragg's (check it out at bragg.com) and another is the Very Low Calorie Diet.
One more success story is that of Rachael Heller, the author of "The Carbohydrate Addict's Diet: The Lifelong Solution to Yo-Yo Dieting." Skipping breakfast just once, by accident, she discovered a way to fight her carbohydrate addiction.
