I was pre-diabetic at an A1C of 6.1. I did the Keto and intermittent fasting and that got me down to 5.8 but I never tried to lose weight....I am not "fat" at 5'10" and 163 pounds. But I do have the "belly fat" and chin fat. I think I can lose 10-15 pounds so that is my new goal. Maybe the weight loss will get my A1C lower.
