Definitely try an LCHF diet. As T2 diabetics we tend to be carbohydrate intolerant, so by eating this way we're managing glucose levels by cutting right down on our carbohydrate consumption. It isn't specifically a weight loss diet though it can be used as such, but to maintain weight you'll basically need to replace reduced carbs with enough fats and oils as your main fuel source to keep your weight stable - you'll lose weight if your body has to use stored body fats to make up any energy deficits.
I lost weight early on low carbing but have maintained a stable weight now for about six years.
