Genetics linked to Obesity

Researchers at Imperial College London led by Dr Tony Goldstone, a Consultant Endocrinologist at Imperial College of London, UK, found that two gene variants – FTO and DRD2 – influenced activity in the brain reward system when looking at pictures of high-calorie foods. The research suggests that part of the reason people with the FTO variant are more likely to have obesity may be because dopamine signals in their brain cause them to feel more reward and craving when presented with high-calorie foods.
