Fasten Support Juice and Daidai Diet

A diet/slimming product at a local beauty shop. There are tons of slimming salons and diet products here, but few have the pedigree of the exclusive Fasten Club. Exactly what is being 'fastened' isn't exactly clear, but this juice apparently supports the process. Combined with the Daidai (die-die?) diet, club members can expect the pounds to just... fasten away?
