I've informally studied the "bariatric surgery" phenomenon for years, and it creates this same kind of trap. Though assertions like this at least point out we can get the short-term, diabetes, results without such drastic steps.

I had been casually acquainted with a couple, lovely people whose BBQ's were absolutely hellish for me. It was a potluck situation, and I discovered the fruit salad I had brought, and the hot dogs and frozen beef patties on the grill, were literally the only foods at this event which were not 90% carbs.

And my hosts and their guests were also, you know, 90% carbs.

So I was sadly not surprised when I found out a few years later that both my hosts had had gastric bypass, that it "stopped working," and they had given up on food-based solutions to their health woes; which were apparently considerable.

This leads me to believe that moving away from gastric surgery for weight loss can only be a good thing. From my observations, it's about 10% success, 80% backsliding, and 10% deadly.
