In his comment on the new findings of this research, Dr Lyn Steffen said "Why is it hapening? Is it some kind of chemical in the diet soda,or something about the behavior of diet soda drinkers?", and I think it is both.

Artificial Sweeteners present in diet soda raises blood sugar the same way. Yet, the more important thing, is the behavior of the diet soda drinkers, since they tend to drink and eat alot of processed foods that basically contain refined grains and their derivatives, and many of those foods admit frying as the main procedure as a processing technique.
