Quick Answer: Do genetics contribute to obesity?

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.

What percentage of obesity is due to genetics?

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.

Are genetics to blame for obesity?

“Common Obesity” Caused by Mutations in Multiple Genes

Evidence from animal models, human linkage studies, twin studies, and association studies of large populations suggests that this variation in our susceptibility to obesity has a genetic component.

Is obesity genetic or environmental?

Obesity is determined by the genetics as well as obesogenic environment [4-5]. It was first studied in 1994 that Ob gene and leptin play an important role in determining the body weight of an individual [6].

How can we prevent genetic obesity?

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.
