This book is intended, to be easy for ages of 9 to 99. Although this book intended mostly for adults, who want to have better health, and lose weight, I have included an appendix, especially for very young people up to 20-25 years old. Under parents’ discretion these very young readers could especially read the annex one. This book is compromised of two sections. Section 1 is the main body of the book it shows you how to diet and exercise. In my opinion, this is the best way possible. Section 2 is called annex chapters. It is used for both reading and referencing.
