Query: Worth checking out from library but not paying for it..

I checked this book out at the local library - glad I didn't actually pay for it. I thought it was interesting and would probably try the diet if I was obese but only having 15 pounds to lose I'm not going to risk it with the shots and STRICT diet. So just check it out at your library and skip right to the chapters where he talks about the diet...
