People with diabetes are unable to control the level of sugar in their blood, usually due to a breakdown in how their bodies use the hormone insulin. It’s not completely clear how obesity can contribute to diabetes, but it is known that excess weight is associated with chronic inflammation and a dysfunctional metabolism. And these factors in turn make it easier for someone to stop responding to the presence of insulin as easily as they once did. So by using surgery to help very obese people with diabetes lose weight, the logic goes, you can indirectly treat or prevent the condition. But doctors such as David Cummings, a senior investigator at the University of Washington’s Diabetes & Obesity Center of Excellence, are pushing back against this way of thinking.
This seems hard to do, but really it’s not if you know one secret: Replace snacking with something far more satisfying — fat. That’s right, the government is wrong to recommend a low fat diet. Fat is what makes you feel full until your next meal. Take away the fat, take away the full. Don’t go to an extreme, but do lean strongly toward a high-fat low-carb diet.
