Is Diabetes Caused By Obesity?
Not everyone with T2 diabetes is obese – only half are in the obese range. ‘There are 10% in the normal range,’ says diabetes expert Professor Roy Taylor. ‘And four out of 10 are overweight.’
Research by his Newcastle University team suggests T2 is caused by too much fat in the liver and pancreas, affecting ability to regulate blood-sugar levels. If you eat more calories than you burn, you store it as fat. First, safely, under the skin then, less safely, in these organs. ‘All it takes is half a gram of extra fat inside the pancreas,’ says Professor Taylor. ‘There’s a bit of the luck of the draw mixed in because, if a person’s insulin-producing cells are not susceptible to fat excess, then they’re unlikely to get T2 diabetes. If they are, they will.’
