Low-carb, high-fat diets add no arterial health risks to obese

Good news, I would say:

Low-carb dieters showed no harmful vascular changes but also on average dropped 10 pounds in 45 days, compared to an equal number of study participants randomly assigned to a low-fat diet. The low-fat group, whose diets consisted of no more than 30 percent from fat and 55 percent from carbs, took on average 70 days, nearly a month longer, to lose the same amount of weight. [...]

However, Stewart does contend that an overemphasis on low-fat diets has likely contributed to the obesity epidemic in the United States by encouraging an overconsumption of foods high in carbohydrates. He says that high-carb foods are, in general, less filling and that people tend to get carried away with how much low-fat food they can eat. More than half of American adults are estimated to be overweight, with a body mass index of 26 or higher; a third are considered to be obese, with a BMI of 30 or higher.
