Atkins diet removes all carbohydrates other than those stored as glycogen in meat and the minimal carbohydrates in green vegetables. Most green vegetables fall into the category that nutritionists used to call 5 percent vegetables, which means only 5 percent of their weight comes from carbohydrates that we can digest and the rest is mostly water and some “roughage,” which we now call fiber and which we barely digest to make use of for fuel.
