Science writer Gary Taubes argues that when it comes to counting calories, dieters need to be thinking about quality, not just quantity.
In his new book, Good Calories, Bad Calories, Taubes combats the long-held belief that all fats are to be avoided. Not all fats are bad, Taubes says; the real culprits when it comes to weight gain are refined carbohydrates and sugars.
