Query: The Spark

This book is 237 pages too long. It is an infomercial. A reader has to wade through empty paragraph after empty paragraph trying to get the essence of the book. I'll save you the money: eat a high fiber, low fat, carbohydrate diet and exercise for 10 minutes three times a day, 5 days a week. One workout should be aerobic, one should be strength-training and one should be stretching. You get your metabolism going stretching the exercise you do over the course of the day. The End!
