Well, there's additional nuance here... Caloric intake is made up of 3 principle inputs: carbohydrates, fat, and protein. The recommended daily allowance of each is in balance, so if you eat fewer carbs, you have to eat more fat or protein to reach your caloric intake. U.S. governmental regulations have long discouraged fat intake, replacing those calories largely with carbs. This was based on the assumption that the fats were harmful, rather than extra calories in general. The article is highlighting a change in understanding that will hopefully have us stop demonizing fats in favor of carbs in a diet that is otherwise within bounds calorically. In short, we know now that it is not necessarily bad to eat fats (anymore than it's bad to over-eat in general).
