"Good Calories, Bad Calories," written by Gary Taubes, an award-winning science writer, is a pioneering book that argues that practically everything we believe about the nature of a healthy diet is incorrect. We've been told that fat is bad for us, carbohydrates are good for us, and that the secret to maintaining a healthy weight is to eat less and exercise more. Despite this guidance, we have seen tremendous obesity and diabetes epidemics. Taubes claims that the problem is with processed carbs such as white flour, easily digestible starches, and sugars, and that the type of calories we consume is more important than the quantity.
