Essentially, the carbohydrate hypothesis states that it is carbohydrates that cause the diseases of civilization -- obesity, diabetes, heart disease, stroke and some forms of cancer. Refined carbs, like polished rice, white flour and white sugar, were pointed out as some of the more dangerous ingredients but high-fructose corn syrup also made the list.
In this hypothesis, it is the quality of the calories consumed that regulates weight, and the quantity--more calories consumed than expended--is a second phenomenonIn summary, part one of the book was "this is why everything you know is wrong" and part two was "this is why everything you don't know is right." The third part of the book promises to discuss weight loss and I'm hoping some sort of recommendations will be made there. There is a lot of information presented for the author not to provide a summary and conclusion.
