Researchers say an extreme diet of 600 calories a day can reverse Type 2 diabetes in people diagnosed with the disease within the previous four years.
Study participants cut their food intake drastically for two months, eating only liquid diet drinks and non-starchy vegetables, the BBC reports.
The low-calorie diet was found to reduce fat levels in the pancreas and liver, and help insulin production return to normal.
According to findings published in the journal Diabetologia, seven out of 11 people studied were free of diabetes three months later.
Experts say more research is needed to see whether the reversal is permanent.
Type 2 diabetes is caused by too much glucose in the blood, as a result of insufficient insulin being produced by the pancreas.
