Can elderly people who are healthy, physically active, and not overweight, develop Type 2 diabetes?
My impression - that is very rare.
The pancreas only has so many squirts of insulin it can put out in its lifetime.
It’s just a matter of how quickly you want to wear it out.
The answer is yes. My Dad got diabetes at age 80 and 9 a pretty controlled diet for the last 30 years of his life.
