Obesity is prevalent in the United States, and it is a risk factor for heart disease. The first question you need to consider before beginning a plan to lose weight for heart health is "Do I actually need to lose weight?" You can use a Body Mass Index (BMI) calculator (good ones are available free online) to see if your weight-to-height ratio is healthy. If you are overweight, losing 5 to 10 percent of your current weight can help lower your risk for both heart disease and diabetes.
Your physician and other professionals such as a nutritionist can help you identify a healthy goal weight and meal plan for achieving that weight.
