Well it worked for me. I managed to lose two and a half stone in 9 months on this diet. I have also been able to stay at my target weight for a year and a half now. I mainly do green days. I think it is a fantastic way of eating. Good luck with it!
I've lost over 2 stone and hubby has lost almost 5 stone. Its the first diet he's understood enjoyed which means his willpower is brilliant. Love the way you can have big platefuls of free food.
