Want to know how much fat is in your body? Use a body fat calculator to see if you're within the healthy range! For example, if a man weighs 60 kilograms and his body fat percentage is 15%, then his body fat content is approximately 9 kilograms, with the remaining 51 kilograms being lean body weight (including bones, muscles, organs, blood, etc.). By consulting a body fat chart, it can be determined that he is within the healthy range. Additionally, everyone's body contains a certain amount of essential fat, which is crucial for maintaining bodily functions. It helps regulate body temperature, protects and cushions internal organs and tissues, and serves as the primary form of energy storage for the body. Therefore, this portion of fat is indispensable.
