10 Ways to Measure Weight Loss
Body Mass Index (BMI)
The body mass index, or BMI, is another means for measuring body fat by calculating a ratio of height to weight. The basic formula is calculated by dividing your height in meters squared into your weight in kilograms.
Basic BMI guidelines are as follows:
- You are underweight if your percentage of body fat is less than 18.5
- Your weight is normal if your percentage of body fat is 18.5 - 24.9
- You're overweight if your percentage of body fat is 25 - 29.9
- You're obese if your percentage of body fat is 30 or greater
While this is a neat little system, it does have its limitations. For example, a person who has a lot of muscle mass or water volume (such as an athlete) will appear to be overweight, while a person who has a small frame and lean muscle may appear to be underweight. Pregnant woman and the elderly will also get inaccurate readings using the standard BMI.
As with any test, it's important to consult with your doctor to find the technique that is right for your body type.
