Here’s a great post from Matt Ridley on the conventional, but wrong, wisdom of low-fat diets. He writes:
There is a strong possibility that the “diabesity” epidemic has been caused largely by the diet police themselves.
The chief source of the anti-saturated-fat message was a politically astute scientist named Ancel Keys. In 1961 he persuaded the American Heart Association to issue guidelines on saturated fat intake. The main evidence came from his study of heart disease in six countries in Europe plus Japan, from which he concluded that low-fat diets led to less heart disease.
…the fat effect was weak: an order of magnitude less than the effect of cigarettes on cancer, for example.
Ridley’s writing here is based on the work of Nina Tiecholz, which I wrote about here and appears to be nearly identical to the work that Gary Taubes did in his books, who I’ve written about before, as well.
This from Ridley’s post is also interesting:
In the past ten years, study after rigorous study has found that animal fat per se is not harmful, does not cause obesity, does not raise the kinds of cholesterol that predict heart attacks, does not increase death rate and is healthier than carbohydrates. For instance, one two-year trial in Israel found that a fat-and-meat “Atkins” diet lowered weight more than either a low-fat or a Mediterranean diet. As Teicholz puts it in her book: “Every plank in the case against saturated fat has, upon rigorous examination, crumbled away.”
Such findings remain too heretical for most diet experts. Those who make them struggle for years to get published and have to couch their findings in cautious language. Those such as Teicholz and Gary Taubes who write books pointing out that this fat emperor had no clothes are treated as pariahs. If anything, the official committees of the diet police are doubling down, demanding that we eat ever less saturated fat.
If you are at all interested in losing weight, Gary Taubes’ books are worth a read.
