Researchers at Newcastle University in the U.K. have shown that at least some sufferers of Type 2 diabetes can be cured by losing weight. I don't believe this finding is entirely original, but they developed further support for it, as reported in The Telegraph.
As they wisecrack, one only needs to lose 1 gram of fat, it's the fat that surrounds the pancreas. In order to do so, you must lose a lot of body weight. Once the 1 gram is gone the pancreas gets busy producing insulin.
Might it be possible to surgically remove the pancreas fat without the starvation diet? Do you suppose that would work? Maybe zap it with something like radio frequency ablation?
The article implies that either Type 2 diabetes causes fat to deposit around the pancreas, or that only some obese people develop the pancreatic fat deposits associated with (causing?) Type 2 diabetes. It seems losing a lot of weight counteracts the disease somehow.
