About the Body Fat Calculator
Toolliyo's Body Fat Calculator is a free online tool that estimates your body fat percentage using various methods. Body fat percentage is the proportion of your weight that is made up of fat. It's a more accurate indicator of overall health than weight alone.
Why Calculate Body Fat Percentage?
Knowing your body fat percentage can be more helpful than just knowing your weight or BMI. A high body fat percentage can indicate a higher risk of health problems, such as heart disease, type 2 diabetes, and high blood pressure. Tracking changes in body fat percentage can also be useful for monitoring the effectiveness of a fitness or weight loss program.
Calculation Methods
This calculator uses the following methods to estimate body fat percentage:
- BMI Method: Uses your Body Mass Index (BMI) along with age and gender to estimate body fat. This method is the least accurate but provides a quick estimate.
- Skinfold Method: Measures the thickness of skinfolds at specific body locations. This calculator uses the Jackson-Pollock 3-site (for men) and 4-site (for women) formulas.
- US Navy Method: Uses height and circumference measurements (neck, waist, and hips for women) to estimate body fat.
