Is obesity caused by genetics or environment?

Is obesity caused by genetics or environment?

Science shows that genetics plays a role in obesity. Genes can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight.

Is obesity caused by environmental factors?

Environmental factors like high fat foods, super-sized portions, fast food consumption play a major role in occurrence of obesity. Individuals are addicted to high fat and calorie, highly palatable and inexpensive foods. Behaviour is one of the factors influencing weight gain.

Can genetic obesity be overcome?

A genetic predisposition to obesity can be overcome, in part, by having a physically active lifestyle. Writing in the American Journal of Clinical Nutrition, Vimaleswaran and co-investigators show that physical activity attenuates the BMI-increasing effects of an FTO (fat mass and obesity-associated) risk allele.

What are five factors that influence obesity?

Obesity is strongly influenced by environmental factors such as poverty, housing condition, work situation, fast-food, and sedentary lifestyles. One reason for the increasing amount of obesity is because of our sedentary lifestyles. According to Ian Mason, “Our children are watching more television,…

How much does genetics impact obesity?

However, recent studies suggest that genetics contribute to 40-70% of obesity with the discovery of more than 50 genes that are strongly associated with obesity. While changes in the environment have significantly increased obesity rates over the last 20 years, the presence or absence of genetic factors protect us from or predispose us to obesity.

Which factors are involved in the etiology of obesity?

Can obesity really be genetic?

Obesity is also a hallmark of several genetic syndromes caused by mutation or chromosomal abnormalities, such as Prader-Willi and Bardet-Biedl syndromes. In these syndromes, obesity is often accompanied by mental retardation, reproductive anomalies, or other problems. ( 2)
