I didn't see any reference to the study, but from the first comment in that video it seems that the doctor said "his body would stop producing insulin" because his blood insulin levels were low? Doesn't sound right to me. [1]"Prediabetes happens when your blood glucose levels are higher than normal, but not high enough to be diagnosed as diabetes. Prediabetes usually occurs in people who already have some insulin resistance." So, it doesn't sound right that he would be pre-diabetic when his blood glucose levels would be low. Seems that doctor made the assumption that because his blood insulin was low, his body would just stop producing it at some point, and that's not how it works.
