As far as I'm concerned the jury is still out on that.
I have been taking it for about 3 weeks. I have lost about 6 pounds but I really don't have much weight to lose, maybe 10 pounds. Although it is true you still have to diet, it seems to take the edge off from the drive to eat more eat more eat more. If you have ever been a tru fattie, you know what I mean by that. In my mind? Maybe, but only time will tell. By the way, at one time I was 100 pounds overweight. I still try to use the weight watchers methods and am at times having trouble until Hoodia came along.???????
