Many people think having a lot of body fat is bad. Social media and adverts often show very thin bodies and praise losing fat quickly. However, doctors say having too little body fat is also dangerous for our health.

The most important reason for this is that fat does more than just affect how we look. Fat stores energy for later, produces hormones, and protects important organs. Body fat also helps keep the body warm and controls other body functions like the immune system. If someone has too little fat, their body cannot work properly and may become weak or sick.

Because of this, the key result is that both too much and too little body fat can harm the body. Doctors now say it is important to have a healthy amount of fat. People should try to be strong and healthy, instead of only trying to be as thin as possible.
