The three main sections of the book set out to evaluate current research pertaining to causation and cardiovascular sequela of obesity. Part I defines obesity, exploring its epidemiology, its genetic and non-genetic influences and its contribution to the problem of cardiovascular disease. Special attention is given to the primary prevention of obesity as a means of avoiding specific sequelae as well as the difficulties experienced by those who try to lose weight. Part II deals with the relatively new and much heralded discovery of obesity related genes the current state of diet drugs and valvular heart disease, and the interaction of obesity and metabolism, hormonal regulation and various other biological systems. Recent basic advances in the biological understanding of obesity are introduced. Part III suggests the most accurate ways of assessing BMI, of defining helpful dietary strategies and of managing the issues involved in the implementation of physical activity and pharmacological intervention as a means to decrease and maintain weight. Quality of life, economic issues and managed care settings are also discussed.
