"People are looking for the miracle cure for their own over-consumption. If
everyone cut portions, bought higher-quality food, ate more slowly and
exercised, then we wouldn't have these fad diets."

It's just good old-fashioned Puritanism, the twin-virtues of
hard work (exercise) and self-denial (small portions of awful tasting
low-fat food). These dietary Puritans hate low-carb because you don't
suffer enough on it.
