Book excerpt: Nutritional Pathophysiology of Obesity and Its Comorbidities: A Case-Study Approach challenges students and practitioners to understand the role of nutrients within the pathophysiology and development of disease, specifically those diseases which develop as a result of obesity. Through a case-based approach, the author presents complex clinical scenarios that require multiple treatment strategies, including targeted diet modification as an adjuvant to medical therapy. The book is divided into 9 modules and 5 appendices each of which covers aspects of obesity and its comorbidities. Within each module, a case is detailed with relevant history, laboratory and physical data, and follow-up information. Each case is followed by a resource section which delineates current understanding of the pathophysiology of the condition, as well as the actions of nutrients and food components shown to modify these processes. A "further readings" section cites current supporting clinical and basic literature as well as published guidelines. - Explores how obesity is a key player in the pathophysiology of many diseases, including diabetes mellitus, chronic renal failure, hypertension, and atherosclerosis - Integrates current understandings of the molecular mechanisms of nutrient action on the processes of disease development and treatment - Presents students and early practitioners with complex clinical scenarios through a practical case-based approach
