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.
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 weight affected by genetics?
The strength of the genetic influence on weight disorders varies quite a bit from person to person. Research suggests that for some people, genes account for just 25% of the predisposition to be overweight, while for others the genetic influence is as high as 70% to 80%.
How do genetics affect childhood obesity?

Can genetic obesity be cured?
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.

Lifestyle issues — too little activity and too many calories from food and drinks — are the main contributors to childhood obesity. But genetic and hormonal factors might play a role as well.
Are parents to blame for childhood obesity?
Pointing the finger of blame at parents for children’s weight gain may be unfair, research suggests. It has been thought that parents’ feeding patterns are a major factor in whether a child is under or overweight.
How can we prevent genetic obesity?
Lin and colleagues conclude: “Our findings show that the genetic effects on obesity measures can be decreased to various extents by performing different kinds of exercise. The benefits of regular physical exercise are more impactful in subjects who are more predisposed to obesity.”
What is the root cause of obesity?
Obesity is generally caused by eating too much and moving too little. If you consume high amounts of energy, particularly fat and sugars, but do not burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat.
What is the best treatment for obesity?

Can obesity damage be reversed?
Barouch says it’s well-known that obesity increases the risk of cardiovascular disease in people, and some studies have shown that by cutting calories and losing weight, some of the detrimental effects of obesity on the heart can be reversed.
