Has anyone done this? I bought the book the other day. I don't usually buy diet books but this one is aparently something you can use forever - you don't come off it once you lose weight, and its by the CSIRO so I trust it. I haven't started it yet, since the cooking it shared in my house, it would require co-operation from everyone. It's a fairly high protein diet, but it isn't restrictive - and the recipes look great.
