I know an old, retired thin, retired engineer, insulin using diabetic.
I mean he keeps his sugars tight! Yes he has "insulin reaction", but no ketoacidosis.
Well I shared with him an article on garlic and diabetes.
He found one clove of garlic in the morning reduced his insulin requirement by one third!
Unfortunately, that active component of Garlic cannot be patented, so you'll have to eat it - raw
Yes, I found 2 teaspoons of apple cider vinegar and honey gave me a boost. Still I lost interest.
It was the same for him and garlic.
