It is generally recognized that the normal body fat percentage is 6% to 14% for adult men and 10% to 14% for women, so the normal body fat percentage is more appropriate within this range. Body fat percentage, also known as body fat percentage, is the percentage of body fat content to body weight, which is expressed as F%, reflecting the amount of fat content in the human body. In addition, in the case of athletes and other people who regularly perform strength training, the body fat percentage may be relatively low, depending on the sport. Body fat percentage can be used as the most intuitive indicator for evaluating the level of obesity. Long-term high-sugar, high-fat diets are likely to lead to an increase in body fat percentage; while long-term malnutrition or suffering from hyperthyroidism, malignant tumors and other diseases, the body fat percentage can be significantly reduced. If the body fat percentage is obviously too high or too low, it is recommended to seek medical examination in a timely manner.
