5 medication-free strategies to help prevent heart disease

4. Maintain a healthy weight

As you put on weight in adulthood, your weight gain is mostly fat rather than muscle. This excess weight can lead to conditions that increase your chances of heart disease — high blood pressure, high cholesterol and diabetes.

One way to see if your weight is healthy is to calculate your body mass index (BMI), which considers your height and weight in determining whether you have a healthy or unhealthy percentage of body fat.

BMI numbers 25 and higher are associated with higher blood fats, higher blood pressure, and an increased risk of heart disease and stroke.

The BMI is a good but imperfect guide. Muscle weighs more than fat, for instance, and women and men who are very muscular and physically fit can have high BMIs without added health risks. Because of that, waist circumference is also a useful tool to measure how much abdominal fat you have. In general, men are considered overweight if their waist measurement is greater than 40 inches (101.6 centimeters, or cm). And women, in general, are overweight if their waist measurement is greater than 35 inches (88.9 cm).

Even small reductions in weight can be beneficial. Reducing your weight by just 10 percent can decrease your blood pressure, lower your blood cholesterol level and reduce your risk of diabetes.

5. Get regular health screenings

High blood pressure and high cholesterol can damage your heart and blood vessels. But without testing for them, you probably won't know whether you have these conditions. Regular screening can tell you what your numbers are and whether you need to take action.

  • Blood pressure. Regular blood pressure screenings start in childhood. Adults should have their blood pressure checked at least every two years. You may need more frequent checks if your numbers aren't optimal or if you have other risk factors for heart disease. Optimal blood pressure is less than 120/80 millimeters of mercury.
  • Cholesterol levels. Adults should have their cholesterol measured at least once every five years. You may need more frequent testing if your numbers aren't optimal or if you have other risk factors for heart disease. Some children may need their blood cholesterol tested if they have a strong family history of heart disease.

Prevention pays

Heart disease is often avoidable. Following a heart-healthy lifestyle doesn't have to be complicated. Find ways to include heart-healthy habits into your lifestyle — and you may well enjoy a healthier life for years to come.
