I took this product when I reached a plateau of my weight loss ( I follow a low carb low glycemic diet-now a lifestyle) and this product over time with my healthy eating and moderate exercise did help me to lose over 20 pounds! I have recommended it to my girlfriends and it is working for them too. I've now gone from nearly 160 to 113.5 lbs! I started taking green tea pills around 135, trying to help to get to 120. And now that I am off of the pills, with my healthy eating and exercise i have reached a very healthy BMI for a 5 ft 2 woman, and havent gained the weight back by going off of them! Over time, with proper diet and exercise, it did work for me and others I know.
