Body fat percentage of 7% means that body fat accounts for only 7% of body weight, which is equivalent to a 50kg person with only 3.5kg of body fat. body fat percentage refers to the ratio of body fat to body weight, which mainly reflects the body fat content. body fat percentage is often calculated using the body fat percentage formula in life, and body fat percentage is often measured clinically using body fat clips, body fat scales, bioresistance method, etc. The normal body fat percentage range for adult women is 20%-25% and for adult men is 15%-17%. Body fat percentage of 7% is lower than the normal body fat percentage range for men and women, commonly found in bodybuilders and some fitness instructors, who usually look stronger and more muscular, but are not in an ideal and respected physical condition. Because a low body fat percentage will reduce the ability to protect the organs in the body, it will also lower the immune system, making it susceptible to external bacterial and viral infections, as well as heart disease, dizziness, blurred vision, fainting and other symptoms. At the same time, it can easily lead to memory loss, lack of concentration, the body’s ability to protect itself from the cold, and endocrine disorders in women, leading to amenorrhea and infertility. It is not usually recommended for normal people to pursue thinness or fitness and deliberately exercise and work out to achieve a body fat percentage of 7%. For people with a body fat percentage of about 7%, it is recommended to gradually reduce anaerobic exercise and properly perform aerobic exercise, such as jogging and swimming. Eat reasonably three meals a day, and consume more high-protein, high-carbohydrate and high-fat foods, such as eggs, milk, rice, noodles, walnuts, beef, etc.
