I was one of the guinea pigs for this program. I have to say I wasn't terribly enthusiastic about it as I've never really worried that much about my weight. But I did it anyway, or most of it but not religiously. To my surprise I lost 8Kg/18lb in just a few weeks, and it has stayed off. My eating habits have changed without me even realising it. I eat smaller portions, and choose healthier foods, and it just seems normal now. It was really that easy.
