Many people think that having extremely low levels of body fat is a good thing. As you have seen in chapter 13, this is not the case. Body fat is essential for the healthy functioning of our body. Fat is important for transporting fat-soluble vitamins A, D, E, and K, which are important for our health. If people reach extremely low levels of body fat, they may have vitamin deficiencies, which can make them susceptible to disease. Fat is a great shock absorber. Many athletes do not want to have extremely low percentages of fat levels because the fat helps protect their body during competition. Fat also serves as "human insulation" and helps regulate body temperature. So, when you hear people talking about their extremely low percentage of body fat, inform them that they need that fat for healthy living.
