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.
Can obesity be caused by genetics?
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 is Bardet Biedl syndrome?
Bardet-Biedl syndrome (BBS) is a genetic condition that impacts multiple body systems. It is classically defined by six features. Patients with BBS can experience problems with obesity, specifically with fat deposition along the abdomen. They often also suffer from intellectual impairments.

Though becoming overweight or obese may not be a choice and shedding excess weight may be difficult, you can lose weight if you choose to.
Why Obesity runs in my family?
Abstract. A number of studies, including the Danish adoption study, have shown that, in adults, the familial resemblance of obesity, as measured by the body mass index (weight in kg/(height in m)2), is mainly due to genes. The body mass index may reflect both fat and fat-free body mass.
Can you beat obesity?
Reducing calories and practicing healthier eating habits are vital to overcoming obesity. Although you may lose weight quickly at first, steady weight loss over the long term is considered the safest way to lose weight and the best way to keep it off permanently.
