It's true about men losing more weight than women in certain diets. I've seen it where a father and daughter went into a program and the father lost 14lbs. in ONE Week while the daughter lost about 3. As I understand it, A1C of 6 is what the Diabetes Association of America and endocrinologists try to stay with, so you are good. I'm not an MD, but I know how difficult weight issues can be. Be well.
