They are supplements so they are supplementary to anyone's eating habits. That said, I am convinced people like her assumed they would lose weight because herbalife is healthy and that means that eating healthy automatically equates to weight loss because that is how black and white their world is. So I would expect they ate the over priced crap in addition to eating mounds of calories while still expecting to lose weight in the same way they order diet soda thinking that somehow nullifies the thousands of calories that they eat with it.
