Why Experts Now Think You Should Eat More Fat
According to a new study from the National Institutes of Health, a diet that reduces carbohydrates in favor of fat ? including the saturated fat in meat and butter ? improves nearly every health measurement, from reducing our waistlines to keeping our arteries clear, more than the low-fat diets that have been recommended for generations. The medical establishment got it wrong.
The high-fat group cut carbs in half and did not avoid butter, meat, and cheese. One year later, the high-fat, low-carb group had lost three times as much weight ? 12 pounds compared with four ? and that weight loss came from body fat, while the low-fat group lost muscle.
