The study of obesity is a good example of a research area where many scientists hold different opinions, for example, which environmental factors have the biggest impact or whether genes or environmental factors play a bigger role.
This is an exciting time for research into genetic and environmental influences on obesity. Advances in molecular biology, pharmacology, and other fields are allowing rapid advances to be made in this arena. Knowledge that there is a genetic component to variations in body wt and composition is not new.
Studies done by different group of researchers have confirmed that external environmental factors which is eating unhealthy diet and inactive lifestyle is not the only reason for the people gaining weight. Furthermore, the genetics also has an effect on obesity.Obesity is when one has too much body fat, and is unable either by genetic or environmental factors to control it. This problem has become more frequent as the society of today is all about consumption, fast food, calories and lack of exercise, as a simple machine is able to do everything one is too lazy to do.The fact that several of these genes were “highly expressed” in the brain tissue suggests that there may be a role of the brain in predisposing some people to obesity, however exactly how such a predisposition works is not yet clear.
Obesity is more than just eating two Big Macs rather than one. Obesity is a lifestyle disease which is spreading rapidly worldwide. Individuals of all age, gender and ethnicity are affected by this disease. Still, a general trend has been observed that women are affected more than the men.Read More
Obesity is a medical condition that is affected by both genetic and environmental factors in both adults and children. According to research, it is indicated that obesity is about 40% genetic and 60% due to environmental factors (Taylor 2).Read More
The obesogenic environment has different effects on different individuals in the same environment, highlighting an underlying, inherited susceptibility to obesity and fat-distribution. For more than a decade, the genetics underlying common forms of obesity have remained elusive although the advent of the GWA approach has started to deliver robust associations to obesity.Read More
Obesity can affect any person from young children to older adults. There are many causes of obesity such as over-eating, genetics, hormones, the environment, and lack of physical activity. There are many effects of obesity like health issues, depression, eating disorders, and death.Read More
The genetic component of risk for obesity is likely to be complex, including genes that affect appetite, personality, as well as how fat is deposited. However, a predisposition to obesity does not mean a child will definitely be overweight and parents should not abandon a healthy lifestyle, as there is good evidence of the benefits of weight reduction on health.Read More
Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. Studies have identified variants in several genes that may contribute to weight gain and body fat distribution; although, only in a few cases are genes the primary cause of obesity.Read More
Environmental causes of obesity. Genetic factors are the forces inside you that help you gain weight and stay overweight; environmental factors are the outside forces that contribute to these problems. They encompass anything in our environment that makes us more likely to eat too much or exercise too little.Read More
Obesity arises from the interactions between an at-risk genetic profile and environmental risk factors, such as physical inactivity, excessive caloric intake, the intrauterine environment, medications, socioeconomic status, and possibly novel factors such as insufficient sleep, endocrine disruptors, and the gastrointestinal microbiome.Read More
Most obesity, however, probably results from complex interactions among multiple genes and environmental factors that remain poorly understood (multifactorial obesity). Any explanation of the obesity epidemic has to consider both genetics and the environment.Read More
Genetic obesity is a great mystery A genetic variant is a site on the human genome where one of the building blocks of the DNA (guanine, adenine, cytosine and thymine) has been replaced by another. This can cause the gene on which the variant is located to behave differently, e.g. by predisposing the person who has the gene to obesity.Read More
