Love that question. I am curious to know about it too.
People in the other thread told me you can loose weight without it too and its just a way for MRC to make more money.
Metabolic DOES get really expensive. I didn't buy in to everything they were trying to sell, and I did lose.
I'm trying to research, and figure what I should be taking now. I'm trying to keep my life simple, though, and not spend too much energy on the wrong thing.
I never used the supplements and lost weight just following the program. They kept pushing them though and the funny thing is I was determined to show them I didn't need them so made sure I stayed on track and show a loss each week
