I am aware and realize that there are other weight loss programs out there. A good many of them have merrit. In my life, I have never tried a weight loss program before until now. Being a results oriented individual, I can only comment on Herbalife and not others. Herbalife not only works, it tastes good too! I am a runner, and with that comes other needs that I know that I can get with Herbalife. In addition to weight loss, I need energy, nutrition, & hydration. All my needs wrapped up in one place. I am more than just an Herbalife Distributor, I am one who uses and relies on the products that I sell. Quite simply, they work!
