Cutting calories and walking around the neighborhood once a day won't reduce the effects of every disease. But for people with diabetes, these fairly simple acts can have a major impact and may even send the illness into remission.

How can this be? Here's what you need to know:


"Many individuals with diabetes underestimate the power of diet and exercise in helping control their blood sugar," said Dr. Kenneth H. Hupart, chief of the division of endocrinology, diabetes and metabolism at Nassau University Medical Center in East Meadow. "Regular exercise and a healthy diet can help achieve consistency of glucose control and improve overall health."

Sometimes it can do more. Dr. Marie Gelato, an endocrinologist and professor of medicine at Stony Brook University Medical Center, said, "Diet and exercise can help patients decrease medication dosage and in some instances eliminate the need for medication."


"Exercises such as walking, swimming or cycling lower blood sugar not only while someone is exercising, but throughout the day," Hupart said. "Thirty minutes of aerobic exercise on most days is what it takes to achieve this benefit." However, he said, consult with your doctor before launching a new vigorous exercise program, especially if you haven't been exercising or if you have heart problems.

Gelato explained that exercise works for people with diabetes by making the body more sensitive to insulin, which processes blood sugar. "When you exercise, you make insulin more effective and able to lower blood sugar," she said.


A loss of 5 or 10 pounds can have a significant impact in terms of easing diabetes, Gelato said. "I just tell people to get started and get out there," she said. "Even if you walk 10 minutes, it's better than not walking 10 minutes. And hopefully you increase it."

Gelato remembers one patient who told her, "I cut down what I was eating and shook my booty." The woman lost 35 pounds and improved her diabetes numbers.


"Some patients need to monitor their blood sugar levels, and they will notice an improvement in their glucose control pretty rapidly" if they're dieting, exercising or both, Hupart said.

"Those who take insulin or other medications that stimulate insulin release may develop low blood sugar and will need to lower their medication doses as diet and exercise continue," he noted.

For diabetics who don't need to monitor their blood sugar frequently, Hupart suggested asking their doctor about a hemoglobin A1c test. "It's a terrific marker for the average control of blood sugar during the past three months, and people who are taking charge of their diabetes care with these kinds of lifestyle changes should be aware of their own A1c levels," he said. "A number less than 7 percent is terrific, and some doctors strive for numbers that are 6.5 percent or lower."


Diet and exercise won't cure diabetes, Gelato warned. However, it can force it into a form of remission, and that can potentially continue as long as the person keeps dieting and exercising, she said.

Hupart added that diet and exercise also won't cure some of the chronic complications of diabetes, such as eye disease, kidney disease and nerve damage.

"However," he said, "you can still alter the course of the progression of these health issues that result from diabetes."
