The thing is, they act like this isn't happening already. My doctor frequently checks and monitors my blood sugar and has scheduled conversations with nutritionists to help me adjust my lifestyle and diet.

This is the fucking standard of care.

These quacks are just perpetuating the myth that doctors "just push meds" and are controlled by "big pharma". It's how conspiracy theories work. You take a small kernel of truth (we treat some diabetes with insulin) and then just make up sinister stories around it.

Edit: what they actually want is to ne able to blame people who have diabetes for having diabetes. That way they are justified in denying them life-saving medication.
