The article does support LC for the most part. which is refreshing. However, I am not sure the math is right.

"individuals should consume about 250 grams of carbohydrates, or a bit more than 10 percent of their daily calories"

If a gram of carbohydrate has 4 calories, 250 grams equals 1,000 calories. If that's 10% of daily intake, good luck on the diet.
