This is Not fake! I took this when it was by prescription only and 120mg. I lost 90 lbs. and it FORCED me to make changes in my diet. Yes, it blocks fat absorption but that doesn't mean you can eat lots of it. The blocked fat becomes an oil that is not easy to contain within the colon. That's just how it works. I had no side effects except that one and I really became mindful of my diet. Obey the rules and you'll have success but only you can make it happen.
