Meal Replacement

I lost 50 lbs of fat eating 6 meals per day but I leveled off before I could lose the last 15. I think my sugar intake is too high, I eat 3-4 cooked meals and then 2-3 replacments each day. Look at this replacement powder that I mix with milk and tell me what you think, I have a suspicion that there is too much sugar in it, thanks in advance.
