For decades we have been taught that fat is bad for us, carbohydrates better, and that the key to a healthy weight is eating less and exercising more.

Obviously, this is not so.” By 1973, after details of the regulation of fat metabolism and storage had been worked out in fine detail, Bruch found it “amazing how little

After four years, eighty-eight of the men had developed symptoms of coronary heart disease. Paul and his colleagues then compared heart disease rates among the 15 percent of the men who seemingly ate the most fatty food with the 15 percent who seemingly ate the least. “Worthy of comment,” they reported, “is the fact that of the 88 coronary cases, 14 have appeared in
