I've tried numerous products to help with my overall health and metabolism. Losing weight was part of my concern as the little belly was starting to arrive at age 48. In 6 weeks I have felt better and more energetic and have lost about 16 lbs! I haven't really changed much in my daily routine but when I wake up I immediately take the Active PK and go about my day. I don't have the weird hungers and can go with breakfast and then dinner without having to each lunch. I'm really impressed and think I'll hit my weight goal of 175 really soon. I went down from 196 to 181 already.
