Discuss the link between genetics and obesity


Obesity has a clear link to genetics, demonstrated by numerous studies showing that obesity does persist in families even where food intake and physical activity patterns differ. However, the escalating obesity epidemic in recent decades supports the idea that, while susceptibility to obesity is genetically and epigenetically determined, the development of obesity itself is the result of a susceptible genome in the presence of a conducive environment. In other words, placing susceptible individuals in an obesigenic environment -- one characterized by plentiful energy-dense, high-fat foods and technological advances requiring little in the way of physical activity -- results in obesity.
