The genetics of obesity are not like other diseases where a single gene variant is the major player instead, obesity is a polygenic problem, meaning that the interaction between numerous genes may contribute to the issue.

Genetics researchers have identified at least two new gene variants that increase the risk of common childhood obesity the meta-analysis is the largest-ever genome-wide study of the common. Importantly, genetic factors can predispose a person to obesity, as well as influence the effectiveness of weight-loss strategies the body relies on cells to process and store energy, and changes in genes that regulate these functions can cause an imbalance that leads to excessive energy storage and weight gain.

This 96-mb survey included 21 genes associated with monogenic forms of obesity in human or mice, as well as 37 genes that function in body weight-related pathways they found that the monogenic obesity-associated gene group was enriched for rare nonsynonymous variants unique to the obese population compared with the lean population. Continued obesity gene study the researchers noticed the fto gene variation when they screened the genes of nearly 2,000 diabetes patients and almost 3,000 people without diabetes in the uk.
Different people exposed to the same environment have different risks of obesity due to their underlying genetics the thrifty gene hypothesis postulates that,. Although genetics and environmental factors do not cause obesity, they do increase a person's chances of becoming overweight or obese many researchers agree that environmental changes (such as the availability of food and a decrease in physical activity) have contributed to the rising numbers of obese people.
