A Mediterranean-style diet could cut the risk of obesity by almost half according to a major new study.
The research on 16,000 people found a diet rich in fruit, vegetables, whole grains and olive oil cut the chance of becoming dangerously overweight by 43 per cent.
Eating a Mediterranean diet has long been linked to better heart health.

But until now, it is unclear whether it could help prevent weight gain.

The new research carried out by the University of Navarra, and Carlos III Institute of Health in Spain, tracked participants for an average of 10 years.
