Prevention:

According to The Diabetes Carbohydrate and Calorie Counter, by Annette B. Natow, Ph.D., R.D., and Jo-Ann Heslin, M.A., R. D., the best diet to help manage and/or prevent diabetes is
a healthy diet, low in saturated and total fats, moderate in protein, low in sweets and high in starches and fiber, yet some people cannot tolerate excessive starch. Only a registered dietitian knows what your needs will really be. But diet is a major key to prevention and management.

Exercise:

Starting and maintaining a good exercise program with your doctor's assistance is a good way to help keep diabetes at bay/managed. According to the University of California, San Diego, exercise improves the ability of the muscles to respond to insulin, and this causes the muscles to take up more sugar, in addition to strengthening the heart and tissues. Contact your doctor before starting an exercise program.

Medication:

Some diabetics treat their diabetes with diet alone. Many use medications or others use insulin. It's very important to keep to your medication schedule and take it on time and as directed. Glucose testing for medication and insulin users is an absolute must. Check your glucose on time and as needed.
