I just got this a couple of weeks ago and am still getting through it but I love it. It really explains in detail proper nutrition, weight loss (and fat loss), cardio and weight training and what to do and how to get in lean, muscular shape. It explains why weight training is so important (high lean muscle mass = high metabolism) better for burning the calories. It explains how to lose body fat (which is more important that weight loss). It says the most efficient approach to fat loss is to decrease your calories a little and your activity a lot. It says to use exercise to burn the fat rather than diets to starve the fat (if your calorie levels get too low, your body goes into starvation mode and you won't lose). It explains why exercise - not dieting is the superior method of losing body fat. It helps you determine your minimal calorie requirements and why you should never drop below them. It tells you to eat more frequently and never skip meals (5-6 meals a day) and why that is so important. It tells you how to determine your fat to muscle ratio and the proper percentage of body fat you should have and how to measure body fat. It shows you how to determine your true ideal weight. It tells you how to break fat loss plateaus and knowing when to push harder and when to rest and recover. It tells you how to determine your body type and how to train with the body type you have. It tells you how many calories you need for maintenance and for losing weight. It tells you that eating frequently makes you burn more calories and 5 or 6 meals a day accelerates your natural rate of calorie burning. It tells you the 12 best foods you should eat all the time and the 12 foods you should never eat. It says aerobic exercise is the real secret to losing body fat and gives you duration guidelines for cardio workouts. It tells you how hard you should exercise, how to calculate your fat-burning heart rate zone and when is the best time to exercise. It also explains whey weight training has to do with losing fat and why you can't succeed without it to lose fat permanently.
Sorry for the long post. These are just some of the things this book tells you. There are just too numerous to mention. I would highly recommend that you get this book even if it is a little pricey. It has a wealth of information in easy to read understandable terms.
