Drawing on modern science and extensive personal experience, the book's author, Tracey Mann, explains why popular diets don't work. And he states: losing weight to fit the imposed patterns is not just pointless, but dangerous to health. A weight at which you are comfortable, at which you feel healthy and satisfied, is the ideal to which you should strive. It is only for this that it makes sense to fight, and Professor Tracy Mann will tell you where to start and how to maintain the result.
