Scientists find how ‘obesity gene’ makes people fat

Scientists have unraveled how a gene long associated with obesity makes people fat by triggering increased hunger, opening up potential new ways to fight a growing global health problem.

A common variation in the FTO gene affects one in six of the population, making them 70 percent more likely to become obese – but until now experts did not know why.

The discovery follows studies of blood samples from people after meals, combined with functional magnetic resonance imaging of volunteers’ brains and cell-based studies looking at ghrelin production at a molecular level.

Batterham said the work provided new insights and possible new leads for treatment, since some experimental drugs are known to suppress ghrelin and could be particularly effective if targeted at patients with the obesity-risk variant of the gene.

The prevalence of obesity is increasing worldwide at an alarming rate and both developed and developing countries are affected. Obesity is a major risk factor for diabetes, heart disease and certain cancers.

At least 2.8 million adults die each year as a result of being overweight or obese and more than 40 million children under the age of five were overweight in 2011, according to the World Health Organization.
