Not if you go low carb and stay low carb. I brought my A1C down from 6.8 to 6.0 in 4 months on a low-carb diet. Most doctors just tell you to stay away from sugar and that’s easy but it’s the bread rice potatoes and other carbs that are hard to avoid and will keep your blood sugar levels up and even get worse.
When Eldest was first told he had Diabetes, he ate mostly meat and lost 100 lbs. A son-in-law who is 6’4” and big-boned chose slow weight loss surgery, he was 400 lbs, lost 200 lbs, and kept it off, but there are drawbacks to the surgery. The type he had didn’t leave flabby skin hanging. But gives him issues with what he can eat. Still looks big, but that is bone structure and height. Lost a TON OF PILLS.
