Heart Disease Risk

The Body Health and Heart Disease Risk results above are based on the following numbers:

Body Health:
Underweight: below 18.5
Normal Weight: 18.5 to 23
Overweight: 23 to 25
Moderately Obese: 25 to 30
Severely Obese: above 30

Heart Disease Risk:
Low Risk 18.5 to 23
Moderate Risk: 23 to 27.5
High Risk: above 27.5

Heart Disease Risk refers to risk of diseases such as high blood pressure, stroke and diabetes. Very low BMI, which means underweight, is also not good for your heart as it weakens it.

Underweight people also run the risk of developing other problems such as osteoporosis and nutritional deficiency.
