4. Maintain a healthy weight

Being overweight — especially around your middle — increases your risk of heart disease. Excess weight can lead to conditions that increase your chances of developing heart disease — including high blood pressure, high cholesterol and type 2 diabetes.

One way to see if your weight is healthy is to calculate your body mass index (BMI), which uses your height and weight to determine whether you have a healthy or unhealthy percentage of body fat. A BMI of 25 or higher is considered overweight and is generally associated with higher cholesterol, higher blood pressure, and an increased risk of heart disease and stroke.

Waist circumference also can be a useful tool to measure how much abdominal fat you have. Your risk of heart disease is higher if your waist measurement is greater than:

• 40 inches (101.6 centimeters, or cm) for men
• 35 inches (88.9 cm) for women

Even a small weight loss can be beneficial. Reducing your weight by just 3% to 5% can help decrease certain fats in your blood (triglycerides), lower your blood sugar (glucose) and reduce your risk of type 2 diabetes. Losing even more helps lower your blood pressure and blood cholesterol level.
