Herbalife

I've personally never tried it. I'm too cheap and would rather get something not peddled by a "dealer".

BUT a friend of mine is a user/dealer and he has lost over 100 lbs. Not sure when he started but it was sometime last year. He loves it but then he is a dealer so he is also trying to sell it.

If you have the $$ for it then you should try it out. If not, just going into a GNC or other health store and they can help you pick out some products that are likely cheaper and just as good for you.

To me it seems like another supplement company selling meal replacements and vitamins while also telling you to eat a healthy diet.... and charging you alot for it. The design of alot of these vitamin and herbal supplements is to not only provide Micronutrients but also to incorporate 'natural diet suppressing' additives. Herbalife for instance, did incorporate some Ephedra based items in previous formulations, but had to remove them in 2002 once banned by the FDA. There have been 3 studies done on herbalife but the results are mixed. The specific quote I saw was "By and large, these studies do not provide convincing evidence that Herbalife products produce more weight loss than other products or than a proper placebo." ( wikipedia )

If it's in your budget I'd say try it. BUT I would try it for a month or two and record your results and then try your own experiment. Drop their supplement formula for a good whole food multivitamin and find a protein powder with a comparable nutrition profile ( I believe herbalife i soy based) and see if your results continue. In my opinion it's Much more about the proper diet.
I listed the 3 cited studies below in case you'd like to check them out. Hope this helps.

2.^ The paper states only that diets were designed to deliver a total calorie intake of 500 calories less than the resting metabolic rate. The 50% reduction can be derived as follows. The resting metabolic rate of a typical study subject, a 49 year old woman with height 1.65 m, weight 100 kg, and BMI 36 is 1600 kcal/day. Her daily intake at low physical activity is about 2200 kcal/d. Her target intake was therefore 1600-500= 1100 kcal/d, 50% of her habitual intake.

Sounds REALLY boring!
