Obesity refers to a disease in which the person accumulates a high amount of fat due to lifestyle with less physical activity but a very high amount of energy intake.
Obesity is not just influenced by the environment but by genetics also. The genetic studies on the accumulation of fat involve more than 200 genes in which one of the genes is fat mass and obesity-associated gene or FTO gene. This gene can cause increased hunger level, reduced satiety, and influence other genes.
