i'll try to answer some question but pls do your own research.

herbalife protein powder contains whey protein concentrate and soy protein isolate which basically means filtered protein which contains no fat, water and other minerals. means it is pure protein which has 100% retention on muscle.

muscle in this case would be prevented from wasting away when dieting.

it is not that herbalife has been the only source of info. i get these info from various bodybuilding website.

as for nutrient that protein diet lacks, herbalife do have a nutrient shake that you mix it with protein. yes u can check the label.

bare in mind the article above me is talking about Atkins diet where the protein is not whey and soy protein concentrated and isolate which contains no fat at all.

yes i am a herbalife member but i do my homework. i cant sell something i don't believe in so if u have new info do let me know

but do your homework too before u say anything because i'm don't have time to entertain super skeptic like u simply because there's lots of people out there who's not too paranoid.
