Carnivore diet. My wife is a diabetic and had high A1C. We went on the carnivore diet and 4 months later went back for our blood work. Our doctor thought he had the wrong results because our blood work came out as perfect as possible. Her A1C looked like an athletes and she is 52 years old and a bit on the heavy side(like i am). Carnivore is such a great cleanse diet/lifestyle. Meat, eggs, cheese, and some milk here and there. Cut out EVERYTHING else. Get that sugar intake to 0. He will feel amazing
