When his feet were figuratively put to the fire of backing his diet with hard evidence, he said that research hasn't been performed. Dr. Atkins said that research hasn't been performed before but soon will. Sounded like back-peddling to me. Complex carbohydrates vs. simple sugars I mentioned earlier that I would later discuss complex carbohydrates and carbohydrate-induced insulin boosts. What you need to understand is that some carbohydrates are worth avoiding and others are not.
Simple sugars are bad news.
If you have these, your blood sugar soars, causes a burst of insulin, which activates fat cell enzymes, facilitating the movement of fat from the bloodstream into fat cells for storage. In other words, they convert to fat easily. This is not entirely true. Simple sugars, one type of carbohydrate, cause this insulin spike. To tell if your food has this, simply look at the ingredients.
