In recent years, we’ve developed a much better grasp of the biological and other factors associated with the development of obesity. Reflecting our evolving understanding of causes and consequences, this new edition examines the history and prevalence of obesity and explores its biological, behavioral, environmental, social, and cultural determinants. The book also examines the consequences of obesity, including economic costs, and describes how excess weight affects and exacerbates a range of comorbid conditions, including diabetes, cardiovascular disease, pulmonary disorders, arthritis, and cancer.
