The diabetics, by consuming just 600 calories a day for eight-weeks, (the same amount many people would eat at lunch alone), were able to throw away their tablets.
Even after 18 months, some of them are still free of the disease, which is linked to obesity and usually attacks in middle age, reports the Daily Mail .
Researchers from the Newcastle University have described the results as remarkable, proving that the condition need not be a life sentence.
"To have people free of diabetes after years with the condition is remarkable and all because of an eight week diet. For many years it has been assumed that Type 2 diabetes is a life sentence. It's chronic, it's progressive, people need more and more tablets, and eventually they need insulin. It's a downhill slope. However, we have been able to show that it is in fact reversible," Prof Roy Taylor, of Newcastle University, told the Daily Express .
According to the researchers, the trial also paves the way for new treatments for those who cannot stick to the drastic diet.
In 'type two' diabetes, the pancreas does not make enough insulin – a hormone key in the conversion of sugar into energy, and the insulin that is made does not work properly.
The condition is often controlled initially with a stringent diet and exercise regime. But many sufferers see their health worsen and eventually have to depend on tablets or insulin injections.
"What is really important and very new is the changes in the body that go along with this. Specifically, the insulin-producing cells in the pancreas have gone to sleep in Type 2 diabetes, they are not really doing very much.
As the level of fat in the pancreas has reduced, we have seen these insulin-producing cells come completely back to normal, and that is truly remarkable," Taylor added.
