There's a growing debate about whether obesity is fuelled by lifestyle or simply by genetics. In this review we will discuss the genetics of body weight regulation including genes encoding factors regulating food/energy intake, genes encoding factors implicated in energy expenditure, and genes encoding factors implicated in adipogenesis as well as syndromic forms of obesity. Do you often think that is obesity genetic there is a link between obesity and genetics see how genetics affects obesity.

Unhealthy food environments and sedentary lifestyles certainly contribute to obesity, but they can't entirely explain weight gain the latest research points to four new genes that could contribute to the most extreme cases of obesity in childhood.
