Changing one's diet is important by removing white bread, rice, potato, and high calorie foods. Whole wheat or whole grain is great, sweet potato, brown rice and healthy smoothies(find online) and vegetables. My A1C is now 6.5 because I lost weight, change diet, and positive attitude. I am now a size 14 my goal is size 10 and I was size 26-28. Start out slow then increase your workout. I was on vacation few weeks ago went off my diet,but I am on track now. Many workouts on youtube for beginners. Remember small meals throughout the day and breakfast is important. You can do it!!
