The New Atkins Book refers to low glycemic. His older ones didn't. He also embraces the ECC (Effective Carbohydrate Count) concept. Still when you actually put a name on the concept of their diet it is "low-carb". The diet lowers your insulin response. The next step for them is to say that early in weight loss it migh be a good idea to lower carbs to 25-50 grams.
You know 4-5 years from now they will discover that dietary ketosis will not kill you and that it has beneficial effects.
Having low carbed for about 8 years now, I am sure ketosis will not kill you (or I would be dead!) Gosh, I was low carb when low carb wasn't cool! And....my ratios are so good that my doctor about had a heart attack when he saw the numbers!
