Lose 12 pounds in 3 weeks claims the book. And after reviewing it, I believe it just might be possible. Written by the author of last year's "The Fat Smash Diet," the idea of this seems to be, if you want big results, you'll have to push yourself beyond normal limits to attain them. Once again, readers will find Dr. Smith's easy and friendly writing style. At the start of the book, you find out your "dieting type" and then quickly go from there. Since the book is set up for you to lose 12 pounds in 3 weeks, its organized in three 1 week cycles, which is 21 days. For each day, there is a menu plan (four meals a day) and a journal page you to write on. Know too that the exercise recommended each day is cardio. Other goodies include recipes, which easily make up about a third of the book, and a handy appendix ends the book (which contains useful info about BMI's, how to read food labels, etc.). All in all, I feel like this is a great book that is well laid out and very user friendly. One caveat though. Following the plan may not be easy at times, and the book will tell you this outright. Nonetheless, it should benefit many who struggle with their weight loss demons. Also suggest "The Sixty-Second Motivator" for readers who have trouble sticking with a weight loss plan.
