Book Description
This book is an edited collection of the literature on leptin beginning with the discovery of leptin and a study of its affect on animals and in humans. Chapters will focus on the discovery, history, roles and regulation of leptin in all the major areas of physiology, as well as on assay methods, phylogeny and genetics. The timing of this volume is long overdue and is the first comprehensive coverage of leptin physiology in the field.

Book Description
The fact that about 30-40% of the adults in the Western world are overweight or obese testifies to the frequency of the disturbances in body weight regulation. Scientists have established that caloric intake, macronutrient composition of the diet, basal and resting metabolic rate, thermic response to food, energy expenditure associated with movement and physical activity, and preferential storage of the surplus of calories as fat or lean tissues are critical determinants of energy balance and body weight. While much has been learned, the field is poised for major advances with the advent of a variety of imaging techniques, progress in quantitative and molecular genetics, use of transgenic rodent models and of breeding experiments with informative inbred strains, availability of stable isotopes for metabolic and behavioral studies, and a growing number of useful experimental animal and human models. This volume takes an integrative approach to obesity. It is structured around four major topics: (1) the animal and human models currently available for the study of body weight regulation with their strengths and limitations, (2) the molecular and genetic basis of the regulation of body weight, (3) the metabolic and physiological mechanisms involved, and (4) the behavioral and social determinants. The 13 background papers provide a critical overview of the present knowledge base while the group reports summarize the extensive deliberations of 38 international experts. Particular emphasis has been given to promising research areas and on the advances needed to ensure a better understanding of the biological and behavioral mechanisms of the regulation of body weight, with a particular emphasis on overweight and obesity.

Book Description
During the last two decades, the prevalence of obesity has dramatically increased in western and westernized societies. Its devastating health consequences include hypertension, cardiovascular diseases, or diabetes and make obesity the second leading cause of unnecessary deaths in the USA. As a consequence, obesity has a strong negative impact on the public health care systems. Recently emerging scienti?c insight has helped understanding obesity as a complex chronic disease with multiple causes. A multileveled gene–environment interaction appears to involve a substantial number of susceptibility genes, as well as associations with low physical activity levels and intake of high-calorie, low-cost, foods. Unfor- nately, therapeutic options to prevent or cure this disease are extremely limited, posing an extraordinary challenge for today’s biomedical research community. Obesity results from imbalanced energy metabolism leading to lipid storage. Only detailed understanding of the multiple molecular underpinnings of energy metabolism can provide the basis for future therapeutic options. Numerous aspects of obesity are currently studied, including the essential role of neural and endocrine control circuits, adaptive responses of catabolic and anabolic pathways, metabolic fuel sensors, regulation of appetite and satiation, sensory information processing, transcriptional control of metabolic processes, and the endocrine role of adipose tissue. These studies are predominantly fuelled by basic research on mammalian models or clinical studies, but these ?ndings were paralleled by important insights, which have emerged from studying invertebrate models.

Book Description
The aim of this book is to provide an updated, detailed and comprehensive account of the field through a cutting-edge analysis by leading experts in the area. To achieve this, the book is divided into three parts, focusing on the peptides operating both centrally and peripherally at the same time as providing an integral and integrated perspective of the multifaceted and complex regulation of energy balance homeostasis. Part I contains three chapters covering the central pathways involved in the control of food intake. The first of these is devoted to the orexigenic neuropeptides, i.e. those that increase or stimulate appetite, while the second is a description of the peptides with anorexigenic effects, i.e. those that decrease or stop food intake. Since this is a rapidly evolving field, the third chapter concentrates on emerging and newly identified factors and their interaction with the already well-known peptides. Part II encompasses six chapters that deal with the peripheral signals participating in energy homeostasis and their control in health and disease. Regulation of body weight was once considered a simple feedback control system in which the hypothalamus modulated food intake and energy expenditure to compensate for fluctuations in body weight. The existing body of evidence has fostered the transition from the classic adipostat, a sensor of body adiposity that informs the hypothalamus about the abundance of energy stores, to a more dynamic and multifactorial model including signals emerging from several different organs such as the gut, the liver, the pancreas and the vascular system. The underlying molecular mechanisms by which adipose tissue enlargement and the subsequent increase in adipokines contribute to the pathophysiological events in the gastrointestinal, hepatic, pancreatic, musculoskeletal, cardiovascular and immune systems are now beginning to be better understood and are covered in detail in this section of the book. Part III contains six chapters providing an integrative approach to current knowledge in energy balance regulation. Adipose tissue biology and the hierarchy of the neural circuitry controlling energy homeostasis deserve special attention, as does the relevance of food reward signals and the links between the homeostatic and hedonic systems. Specific chapters address the available advances in technology to analyse these complex issues, including functional neuroimaging and the whole range of the 'omics' strategies. The final chapter takes a fresh and innovative look at future potential approaches to obesity management.

Book Description
Understanding the relationship between energy balance and obesity is essential to develop effective prevention programs and policies. The International Agency for Research on Cancer convened a Working Group of world-leading experts in December 2015 to review the evidence regarding energy balance and obesity, with a focus on low- and middle-income countries, and to consider the following scientific questions: (i) Are the drivers of the obesity epidemic related only to energy excess and/or do specific foods or nutrients play a major role in this epidemic? (ii) What are the factors that modulate these associations? (iii) Which types of data and/or studies will further improve our understanding? This book provides summaries of the evidence from the literature as well as the Working Group's conclusions and recommendations to tackle the global epidemic of obesity.
