A body fat rate of 4% means that every muscle in the body will be very clear, and every movement can see the vibration of the muscles you are practicing. Generally, some bodybuilders and contestants will not pursue such a body fat rate, and the body fat rate will remain at around 4%, so they are called mummies. Unless you are a competitive bodybuilder and know your body very well, don't reduce your body fat to such a low level, otherwise your hormone level will be disordered, your organs will be affected and it will take a long time to return to normal.

Healthy body fat rate standard

Although we all hate fat, in fact, fat has many important functions in the body, such as protecting organs from damage, maintaining body temperature, producing hormones and other chemicals and so on. Therefore, everyone must have a certain amount of fat to maintain normal physiological functions. The research shows that in any case, the lowest body fat for men can reach about 4-5%, and the lowest body fat for women is about 10- 12%.

The reason why body fat can't be lower is that the rest is "essential fat", which is stored around nerve cells, brain tissues, joints, palms and soles, and major organs such as the heart and intestines. You need these fats to survive. When you reach this body fat range, your life may be affected.
