How to measure body fat percentage

By measuring the height and weight of the body, the proportion of fat in the body is calculated. Men need to measure their height, neck circumference and waist circumference; Women should measure their height, neck circumference, waist circumference and hip circumference.

(1) female body fat formula: parameter a = waist circumference × 0.74; Parameter b = weight × 0.082+34.89; Body fat weight = a-b; ; Body fat percentage (body fat percentage) = (total body fat weight/body weight) × 100%.

(2) male body fat formula: parameter a = waist circumference × 0.74; Parameter b = weight × 0.082+44.74; Body fat weight = a-b; ; Body fat percentage (body fat percentage) = (total body fat weight/body weight) × 100%.

2, fat clip:

Pick up the subcutaneous fat in a specific part of the body by hand, measure the thickness with a fat clip, and calculate the approximate body fat rate by using the relevant formula.

3, biological current resistance analysis:

Commonly known as fat pound, it estimates the fat rate in the body through the resistance of different parts of the body, such as water, muscle and fat. More accurate fat scales, such as the InBody in the fitness room, will release micro-currents from the palms and soles of the feet and flow all over the body. If you only measure the fat proportion of the soles of your feet, the results will inevitably be inaccurate.

4, underwater weighing method:

Using the special equipment in the laboratory, the density of human body is calculated by "Jacqueline Theorem", and then the proportion of fat is calculated by formula.

5. Dual energy X-ray absorption method (DEXA):

According to the principle that different tissues (minerals, lean meat and fat) have different absorption rates of X-rays, the fat content in the body is measured.
