“I take it then that this is not at all associated with intentional weight loss from improved diet and exercise?”
That was my question, too.
My friend in her early 70s was told that she was moving up to borderline diabetes. She was probably technically overweight, but not fat or heavy. She was told to lose weight and change her diet so went no sugar / low carb, and Silver Sneakers 3X/week.
The weight melted off quickly and the blood sugar corrected.
In less than a year she was diagnosed with metastatic breast cancer after being cancer free for 40 years.
Probably coincidence. Anyhow, we lost her in 2018.
My condolences over losing a friend.
I don’t know what Silver Sneakers is. A regime of walking or running for old people?
