Body Fat Percentage: Understanding and Measurement Methods
Ways to Calculate Body Fat and Related Health Concerns
What is Body Fat Percentage?
Body fat percentage is defined as the amount of fat in the body divided by the total body weight, which includes muscles, water, and organs. Regularly monitoring body fat percentage is crucial, as an increase in body fat can lead to serious health problems, such as heart attacks, strokes, arterial diseases, and diabetes. This article explores several methods for conducting this measurement.
How to Calculate Body Fat in the Body
Body Mass Index (BMI) Method
To calculate BMI, divide body weight in kilograms by height in meters squared. If the result is between 18.5 to 24.9, the body fat percentage is considered normal. If it falls between 25 to 29.9, the weight is considered overweight, and a result above 30 indicates obesity, which may increase the risk of various diseases.
Waist Measurement
Using a measuring tape, if the amount of fat in the abdominal area is substantial, the individual may be at risk of heart diseases. For an accurate measurement, stand upright and wrap the tape around the waist specifically at the area just below the navel. Ensure only wearing underwear, take a deep breath, and then read the result immediately. Risk is present when measurements exceed 89 cm for women and 101 cm for men.
Skinfold Calipers
This method, commonly referred to as ‘pinching’, involves using calipers to pinch the skin in specific areas of the waist, then converting the results to an approximate body fat percentage using a specific equation that may rely on three or seven measurements. It is important to note that this method may yield inaccurate percentages, especially in cases of underweight or extreme obesity. The individual employing this method should apply consistent pressure across all measurement sites.
Bioelectrical Impedance Analysis
This technique relies on the electrical resistance of the body to determine the amount of fat compared to other cells or tissues, as fat is characterized by its inability to conduct electrical currents, unlike bones and muscles. This method boasts a 95% accuracy rate. To conduct this measurement, one must stand barefoot on a plate that emits electrical currents, ensuring not to eat or drink for three hours prior to the test.
