Body Fat Calculator

体脂肪を計算する簡単な方法。

The best time to use this Calculator, is in the morning. Your body weight and waist measurements are the most accurate just after you wake up from 7-8 hours of sleep.

This will not calculate your exact body fat percentage. The most accurate way is underwater weighing, but this formula should give you a consistent measurement you can use as a guideline so you can determine if you're losing body fat and/or muscle.
