BMI (Body Mass Index) is a useful measure of underweight, normalweight, overweight and obesity. Measure and keep control of amount of fat present in your body.
BMI Calculator is simple iPhone app that keeps you in updated about the fat in your body.
BMI is an estimate of the fat in the body and a good gauge of the potential risk for diseases that can occur with more body fats. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers.
BMI is used for most men and women, but BMI calculations have some limitations:
Overestimate body fat for athletes and some others like body builders or those who have muscular build.
Underestimate body fat in kids and older persons and others who have lost their build / muscles.
The BMI score means the following:
Weight
BMI
Underweight
Below 18.5
Normalweight
18.5–24.9
Overweight
25.0–29.9
Obesity
30.0 and Above
People who are obese Level 1, obese Level 2 or obese Level 3 (BMI greater than or equal to 30) or those who are overweight (BMI of 25 to 29.9) have two or more health risk factors, it is highly recommended that they should lose weight. A small weight loss (5 and 10 percent of the current weight) will help lower the risk of developing diseases that are associated with obesity. People who are overweight, do not have a high waist measurement, and have fewer than two risk factors may need to prevent further weight gain rather than lose weight.
Talk to your doctor to see whether you are at an increased risk and whether you should lose weight. Your doctor will evaluate your BMI, waist measurement, and other risk factors for heart disease and any other.
