Insulin and weight gain often go hand in hand, but weight control is possible. If you need insulin therapy, here's how to minimize — or avoid — weight gain.By Mayo Clinic Staff
Weight gain is a common side effect for people who take insulin — a hormone that regulates the absorption of sugar (glucose) by cells. However, controlling your weight is not only possible, but also an important part of your overall diabetes management plan.
When you take insulin, glucose is able to enter your cells, and glucose levels in your blood drop. This is the desired therapeutic goal. But if you take in more calories than you need to maintain a healthy weight — given your level of activity — your cells will get more glucose than they need. Glucose that your cells don't use accumulates as fat.
Eating healthy foods and being physically active most days can help you prevent unwanted weight gain. The following tips can help you keep the pounds off:
- Count calories. Eating and drinking fewer calories helps you prevent weight gain. Stock the refrigerator and pantry with fruits, vegetables and whole grains. Plan for every meal to have the right mix of starches, fruits and vegetables, proteins, and fats. Trim your portion sizes, skip second helpings and drink water instead of high-calorie drinks. Talk to your doctor, nurse or a dietitian about meal-planning strategies and resources.
- Don't skip meals. Don't try to cut calories by skipping meals. When you skip a meal, your body is less efficient at using energy, and you're more likely to make poor diet choices at the next mealtime because you're too hungry. Skipping meals can also cause low blood sugar levels if you don't adjust your insulin dose.
- Be physically active. Physical activity burns calories. A reasonable goal for most adults, set by the Department and Health and Human Services, is at least 150 minutes a week of moderately intense aerobic activity — such as walking, bicycling, water aerobics, dancing or gardening — plus muscle-strengthening exercises at least two times a week. Talk with your doctor about activities and exercises that are appropriate for you.
- Ask your doctor about other diabetes medications. Some diabetes medications that help regulate blood glucose levels — including metformin (Fortamet, Glucophage, others), exenatide (Byetta), liraglutide (Victoza) and pramlintide (Symlin) — may promote weight loss and enable you to reduce your insulin dosage. Ask your doctor if these or other medications would be appropriate as part of your diabetes treatment plan.
- Take your insulin only as directed. Don't skip or reduce your insulin dosages to ward off weight gain. Although you might shed pounds if you take less insulin than prescribed, the risks are serious. Without enough insulin, your blood sugar level will rise — and so will your risk of diabetes complications.
