I've stuck with this diet for 10 weeks. It is so flexible and being able to choose between different styles of eating has been great. I tried the two meals a day plan and to my surprise, I love eating this way. As the plan includes exercises, mindfulness, education and online support, it's got everything in one place and you can dip in and out, fully commit to all the extras or something in between. My fitness levels have improved to the point that I feel I'm almost back to my old self. The plan is so cheap for what you get. I would recommend thefast 800 to anyone.
