How to prevent Type 2 Diabetes!

Although the genes you inherit may influence the development of type 2 diabetes, they take a back seat to behavioral and lifestyle factors. Data from the Nurses’ Health Study suggest that 90 percent of type 2 diabetes in women can be attributed to five such factors: excess weight, lack of exercise, a less-than-healthy diet, smoking, and abstaining from alcohol.

Among 85,000 married female nurses, 3,300 developed type 2 diabetes over a 16-year period. Women in the low-risk group were 90 percent less likely to have developed diabetes than the rest of the women. Low-risk meant a healthy weight (body mass index less than 25), a healthy diet, 30 minutes or more of exercise daily, no smoking, and having about three alcoholic drinks per week.


Similar factors are at work in men. Data from the Health Professionals Follow-up Study indicate that a “Western” diet, combined with lack of physical activity and excess weight, dramatically increases the risk of type 2 diabetes in men.

Information from several clinical trials strongly supports the idea that type 2 diabetes is preventable. The Diabetes Prevention Program examined the effect of weight loss and increased exercise on the development of type 2 diabetes among men and women with high blood sugar readings that hadn’t yet crossed the line to diabetes. In the group assigned to weight loss and exercise, there were 58 percent fewer cases of diabetes after almost three years than in the group assigned to usual care. Even after the program to promote lifestyle changes ended, the benefits persisted: The risk of diabetes was reduced, albeit to a lesser degree, over 10 years.

Similar results were seen in a Finnish study of weight loss, exercise, and dietary change, and in a Chinese study of exercise and dietary change.

Simple Steps to Lower Your Risk
Making a few lifestyle changes can dramatically lower the chances of developing type 2 diabetes. The same changes can also lower the chances of developing heart disease and some cancers.

Control Your Weight
Excess weight is the single most important cause of type 2 diabetes. Being overweight increases the chances of developing type 2 diabetes seven fold. Being obese makes you 20 to 40 times more likely to develop diabetes than someone with a healthy weight.


Losing weight can help if your weight is above the healthy-weight range. Losing 7 to 10 percent of your current weight can cut your chances of developing type 2 diabetes in half.

Get Moving—and don’t be a couch potato!
Inactivity promotes type 2 diabetes. Working your muscles more often and making them work harder improves their ability to use insulin and absorb glucose. This puts less stress on your insulin-making cells.

Long bouts of hot, sweaty exercise aren’t necessary to reap this benefit. Findings from the Nurses’ Health Study and Health Professionals Follow-up Study suggest that walking briskly for a half hour every day reduces the risk of developing type 2 diabetes by 30 percent.

Tune Up Your Diet
Four dietary changes can have a big impact on the risk of type 2 diabetes.
  1. Choose whole grains and whole grain products over highly processed carbohydrates.
  2. Skip the sugary drinks, and choose water, coffee, or tea instead.
  3. Choose good fats instead of bad fats.
  4. Limit red meat and avoid processed meat; choose nuts, whole grains, poultry, or fish instead.
If You Smoke, Try to Quit
Add type 2 diabetes to the long list of health problems linked with smoking.
Smokers are roughly 50 percent more likely to develop diabetes than nonsmokers, and heavy smokers have an even higher risk.


Limit your alcohol intake
Too much alcohol can lead to weight gain and may increase your blood pressure and triglyceride levels. Men should have no more than two standard drinks a day and women should have no more than one.


Control your blood pressure
Most people can do this with regular exercise, a balanced diet and by keeping a healthy weight. In some cases, you might need medication prescribed by your doctor.


The Bottom Line: The key to preventing type 2 diabetes can be boiled down to five words: Stay lean and stay active.
