Three genes could explain why some people are obese but healthy, say scientists

Being overweight is a risk factor for diabetes and other diseases; genes could explain why 15-20% of obese people seem to suffer no health consequences

Scientists have offered a genetic explanation for why some people are obese and healthy while others develop diabetes and heart disease as a result of their weight.

The study identified three genes, which appear to influence whether fat is compartmentalised and stored around the outside of the body or whether it spills into the circulatory system. Higher levels of fat in the blood supply increase the risk of type 2 diabetes and can lead to fatty deposits around the heart and liver.
