Parameter b= Body weight (kg) x 0.082+34.89

Body fat weight (kg) =a-b

Body fat percentage = (total body fat ÷ body weight) ×100%

About body fat percentage BFR
Body fat percentage refers to the proportion of body fat weight in the total body weight, also known as body fat percentage, which reflects the amount of fat content in the body. Knowing your body fat percentage (body fat percentage) can also help you decide if your weight loss goals are realistic. Remember, losing weight is not the same as losing weight. Measuring requires developing good habits, even when using equipment to measure. The best time to measure is in the morning. Right after you wake up from a good night's sleep (7-8 hours), measurements of your weight, waist circumference, etc. are most accurate.

A certain amount of fat is very important for some functions of the body. Fat maintains body temperature, acts as a buffer and insulates organs and tissues, and is the body's main form of energy storage.

The ideal body fat percentage, if the body fat of men more than 25%, if the body fat of women more than 30% can be judged as obesity.

Pay attention to body fat percentage and develop healthy lifestyle habits.
