This cookbook offers a fun introduction to easy diet menus based on accurate knowledge, two-week menus for each season to help you lose weight throughout the year, and tips and basic knowledge about dieting – content rarely found in cookbooks. "Supervised by Yoshio Ikeda, Director of the Tanita Weight Research Institute" A few sections (the table of contents) have been marked with a highlighter, but there are no other scratches or stains. The condition is almost as good as new. I have stored it unused for several months, so I would appreciate your understanding.
