This astounds me that they had to do new research to make this momentous discovery.

Do they even know anything at all about the history of diabetes treatment? That until the development of injectible insulin, the ONLY way to treat it was by reducing dietary carbohydrates? Sounds like they're completely ignoring that detail, and the fact that when it was the only way to treat it, that's what was done.

Besides, even if they now acknowledge that losing weight isn't absolutely necesary, if all the patient does is to cut carbs while increasing protein and fats, chances are still pretty good they'll lose some weight along the way.

Of course that depends on just how much they're cutting carbs in their "reduced carbohydrate" diet though. If it's cut from hundreds of carbs/day to "only 120 carbs/day", that's not going to help all that much. Cut way down, most likely to less than 50/day, they'll see some real progress.
