A study in the journal of Nutrition compared metabolic marker changes in two groups of obese diabetic subjects. One group followed a low-calorie diet and the other group was on a low-carbohydrate, ketogenic diet (LCKD). Both groups had favorable changes but they were more marked - i.e., greater improvement - in the LCKD group. "Therefore, diabetic patients on a ketogenic diet should be under strict medical supervision because the LCKD can significantly lower blood glucose levels." Love those kinds of problems! Better watch carefully, you might get healthier faster than you expect and you might need to go off some of your diabetic medications, faster than you expect!
