You are on quite a cocktail of diabetes drugs, so you need to be very careful if you radically alter your diet. The less carbs you eat, the lower your blood glucose levels will be, which usually means that if you follow this diet for a period of time you will need to discuss your medication requirements with your doctor/nurse as the dose may need reducing.
However, a low carb diet is very successful in reducing blood glucose levels, so better than just plodding on and getting more and more medication.
