A good kick in the butt weight loss book that reminds you to be honest with yourself, and doesn't make you stick to any fad diet, just the science of calories in, calories out. My only complaint: It was too short, I read it in a couple of hours (I have the Kindle edition, which at 1994 locations, is small for $10!). I wish there would have been more in depth information on how to train yourself, but I think this might just be a taste so that people actually sign up with his certified therapists. Really, this book can be summed up as: Think positive, tell yourself you can do it, eat far below your metabolism, deal with the hunger pangs and just starve yourself thin on the weekdays, and eat up to your base metabolic intake on weekends. Then, when you get thin, don't eat any more than you need to - for a 5'4" woman, regardless of weight, that should be NO more than 1,800 calories a day. Less on some days if you want to eat more on others. Super simple, really smart advice, and he suggests you take a long, hard look at your habits and don't lie to yourself - because we're all just fat because we eat too much! That's it. I find it interesting that all of the other people who reviewed this little book ALL gave it 5 stars and none of them have ever reviewed any other books. It made me skeptical to buy it, but, I gave it 4 stars since it renewed my enthusiasm to try again, and I can tell you, the advice DOES work since it's just plain science and I've done it before. Add in exercise to about 1,000 calorie diet and you will be dropping weight like crazy.
