Is there a relationship between genetics and obesity?

I currently have a good exercise regimen and maintain an ideal weight, but there was a time in my life that I was overweight. Investigating I found that in recent studies, scientists have discovered that genetics play an important role in the development of obesity, however, they have not yet been able to locate the gene responsible. In fact, most of the potential genes identified so far affect only small groups of people.

. In an investigation of common genetic variables, experts analyzed the genome of the participants. They found an indicator that is associated with the body mass index, apparently, increases the risk of obesity up to 30%. The scientists tested the degree of predictability of this indicator in 5 different groups. In four of them there was a direct association between a high body mass index and an increased risk of being overweight. Studies continue, but everything indicates that, in effect, there is a genetic predisposition.
