If you haven't guessed, this ploy is what happens when Amway meets the Beverly Hills Diet. Nowhere in the product literature is there any significant emphasis on exercise and behavior modification. The individual who is selling HerbaLife is a registered nurse, which sadly is no guarantee that the product is medically sound. Suffice it to say that no serious medical advice should be taken from anyone selling a product through multilevel marketing. Increasing muscle mass through regular exercise and eating a balanced diet never seem to occur to the suckers that HerbaLife seeks.
Testimonials have zero scientific value.
In fact if you hear testimonials, run like hell. If testimonials are the centerpiece of the pitch, it's a sure sign that no meaningful research has been conducted. If the Herbalife pitch works, then the buyer is encouraged to buy a boxload of the product and pitch it to others. There is no shame in the health fraud industry. Wynar is a physics graduate student.
