Query: Just another diet

I was very disappointed by this book. It contains relatively little information about controlling portion size, and the cut-outs, which the author makes a big deal of, are few and not terribly useful. I expected a new approach to eating moderately and sensibly, but this is nothing more than another reduced-calorie diet that will not be realistic for most people. There's ample research that this type of temporary weight-loss plan does not produce lasting results. I wouldn't recommend that anyone buy this book.
