My Goodness,
With the words Metabo and SPEED both in the name PLUS that XXX it MUST be good!
I'll bet Bette and Oprah have together lost several TONS on the various gimmicks they've tried. Maybe eventually they'll find something that works so they don't have to go on 15 different "diets" every year.
In Oprah's defense, she probably owns half the companies that she touts and ALL the books (smart lady, that Oprah)...her dieting has made her MEGA RICH (as opposed to we poor slobs who get poorer with every new SUPER weight loss pill!)
