Genes And Obesity

This book provides a comprehensive compilation of the evidence available regarding the role of genetic differences in the etiology of human obesities and their health and metabolic implications. It also identifies the most promising research areas, methods, and strategies for use in future efforts to understand the genetic basis of obesities and their consequences on human health. Leading researchers in their respective fields present contributed chapters on such topics as etiology and the prevalence of obesities, nongenetic determinants of obesity and fat topography, and animal models and molecular biological technology used to delineate the genetic basis of human obesities. A major portion of the book is devoted to human genetic research and clinical observations encompassing adoption studies, twin studies, family studies, single gene effects, temporal trends and etiology heterogeneity, energy intake and food preference, energy expenditure, and susceptibility to metabolic derangements in the obese state. Future directions of research in the field are covered in the book as well.

A number of genes have been identified that are associated with an increased body mass index (BMI), the standard measurement of obesity. By analyzing these genes, researchers hope to gain a better understanding of what causes obesity and develop ways to tackle the problem. The study of genes and obesity could lead to new treatments. Genes and Obesity reviews the latest developments in the field. This series provides a forum for discussion of new discoveries, approaches, and ideas Contributions from leading scholars and industry experts Reference guide for researchers involved in molecular biology and related fields

Explains obesity and how genes can be linked to the condition.

The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.

In the past four years, many genetic loci have been implicated for BMI from the outcomes of genome-wide association studies (GWAS), primarily in adults. Insulin-induced gene 2 (INSIG2) was the first locus to be reported by this method to have a role in obesity but replication attempts have yielded inconsistent outcomes. The identification of the second locus, the fat mass- and obesity-associated gene (FTO), h has been more robustly observed by others. Studies from both FTO knock out and FTO overexpression mouse model support the fact that FTO is directly involved in the regulation of energy intake and metabolism in mice, where the lack of FTO expression leads to leanness while enhanced expression of FTO leads to obesity. Along with numerous other studies, a number of genetic variants have been established robustly in the context of obesity, giving us fresh insights into the pathogenesis of the disease. This book will give a comprehensive overview of efforts aimed at uncovering genetic variants associated with obesity, which have been particularly successful in the past 5 years with the advent of genome-wide association studies (GWAS). This book will cover this state of the art technology and its application to obesity in great detail. Topics covered will include genetics of childhood obesity, genetics of syndromic obesity, copy number variants and extreme obesity, co-morbidities of obesity genetics, and functional follow-up of genetic variants.​

In an age of misinformation and pseudo-science, the world is getting fatter and the diet makers are getting richer. So how do we break this cycle that’s literally killing us all?Drawing on the very latest science and his own genetic research at the University of Cambridge, Dr. Giles Yeo has written the seminal “anti-diet” diet book. Exploring the history of our food, debunking marketing nonsense, detoxifying diet advice, and confronting the advocates of clean eating, Giles translates his pioneering research into an engaging, must-read study of the human appetite.In a post-truth world, Gene Eating cuts straight to the data-driven facts. Only by understanding the physiology of our bodies, their hormonal functions, and their caloric needs can we overcome the mis- information of modern dieting trends, empower ourselves to make better decisions, and achieve healthy relationships with food, our bodies, and our weight.Inspiring and revelatory, filled with lively anecdotes and fascinating details, Gene Eating is an urgent and essential book that will change the way we eat.

Although cardiovascular disease remains the leading proximate cause of death in the United States, it is now estimated that obesity may be equivalent to smoking as the leading cause of preventable death in America. In light of these statistics, this reference presents our current understanding of the epidemiology, pathology, and genetics of the obesity epidemic and its relationship to cardiovascular disease. It provides an evidence-based approach to the topic, as well as emphasizes a combined treatment strategy for patients suffering from both obesity and cardiovascular disease.

This report issues a call for urgent action to combat the growing epidemic of obesity, which now affects developing and industrialized countries alike. Adopting a public health approach, the report responds to both the enormity of health problems associated with obesity and the notorious difficulty of treating this complex, multifactorial disease. With these problems in mind, the report aims to help policy-makers introduce strategies for prevention and management that have the greatest chance of success. The importance of prevention as the most sensible strategy in developing countries, where obesity coexists with undernutrition, is repeatedly emphasized. Recommended lines of action, which reflect the consensus reached by 25 leading authorities, are based on a critical review of current scientific knowledge about the causes of obesity in both individuals and populations. While all causes are considered, major attention is given to behavioural and societal changes that have increased the energy density of diets, overwhelmed sophisticated regulatory systems that control appetite and maintain energy balance, and reduced physical activity. Specific topics discussed range from the importance of fat content in the food supply as a cause of population-wide obesity, through misconceptions about obesity held by both the medical profession and the public, to strategies for dealing with the alarming prevalence of obesity in children. "... the volume is clearly written, and carries a wealth of summary information that is likely to be invaluable for anyone interested in the public health aspects of obesity and fatness, be they students, practitioner or researcher." - Journal of Biosocial Science
