How does genetics affect childhood obesity?

How do genetics affect 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.

How much of childhood obesity is genetic?

New research suggests that about 35 to 40 percent of a child’s weight predisposition is inherited from mom and dad. In some cases of childhood obesity, the genetic impact may be as high as 55 to 60 percent.

Why are parents the cause of childhood obesity?

Experts: Obesity Is Biologically ‘Stamped In,’ Diet and Exercise Won’t Cure It. New research into the biological mechanisms of obesity suggests eating less and exercising more aren’t enough for people with long-term weight problems.

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.

Are parents to blame for childhood obesity?
