To increase your sensitivity to insulin, maintain an active lifestyle. Studies have shown that insulin has a stronger effect on those who engage in plenty of physical activity. This will make sure your blood sugar levels stay in a healthy range, and will make it easier for you to manage your diabetes.
When eating healthy for a Diabetic diet, compare the items various stores sell and see who has the best prices on specific items. I like to keep a spreadsheet on my phone which shows each item I buy regularly, and which store I can get it at the best price so I can stock up when I go to that store.
If you are battling illness, you should increase the frequency of your glucose readings. When your body is devoting its resources to fighting off infection, blood sugars can fluctuate in response to the physical and emotional stress that is often linked with sickness. Check glucose and urine ketone levels as often as six times daily during your illness.
