Obesity is a multi-factorial disease, in which an excess of accumulated body fat can reach levels capable of affecting health. It results from an interplay between environmental factors, eating behavior, genes, epigenetics, and neuronal stimuli. The main aim of this book is to provide a state-of-the-art revision about the molecular mechanisms underpinning the development of obesity, reviewing the current knowledge in areas like monogenic and polygenic obesity forms, but also providing an updated view of the emerging knowledge about epigenetics, nutrigenomics, and neuronal aspects that also...
