Because he is not a normal person (that is, he has no fat), and he will die early if he is tired from work and other things.

Fat is absolutely necessary! ! ! !

Fat: the fuel of metabolism

Fat is a lipid substance, composed of fatty acids, which are divided into saturated fatty acids and unsaturated fatty acids. Some unsaturated fatty acids cannot be synthesized in the body and must be supplied by ingested food, so they are also called essential fatty acids. Fat is an important nutrient that makes up the body and cells.

Provide the calories needed by the human body

After oxidation, fat turns into carbon dioxide and water, releasing heat. The heat generated by fat is about 2.2 times that of the same amount of protein or carbohydrates, and it is an important source of body heat.

Regulate physiological functions

Fat stores "fuel" for the body. After eating fat, the excess will be stored in the body and released when the body needs calories. Fat is not a good heat conductor, so subcutaneous fat tissue prevents body temperature from dissipating and maintains body temperature. In addition, fat also protects internal organs, moisturizes the skin and protects against shock.

Constitutes body tissues and biologically active substances

Fat is an important component of body cells, especially brain nerve cells. It is also an important component of body tissues and biologically active substances. For example, phospholipids and glycolipids are the main components of cell membranes. Important organs such as the liver and kidneys also contain a lot of fat.

Dissolved nutrients

Some vitamins that are insoluble in water but only soluble in fat can only be absorbed and utilized by the body in the presence of fat.

Lipids are the energy store of the body

Lipids are the general term for fats and lipids

Animal oils and vegetable oils are the main sources of lipids in our bodies. Vegetable oils mainly include: vegetable oils containing saturated fatty acids, such as coconut oil; neutral oils containing monounsaturated fatty acids, such as olive oil; oils containing polyunsaturated fatty acids, such as sesame oil, corn oil (corn germ oil), soybean oil, Rapeseed oil, peanut oil, etc. Among them, sesame oil is rich in nutrients and rich in vitamin E. It enjoys the reputation of "King of Vegetable Oils" and "anti-aging medicine" and can improve human immune function.

So fat is very important to the human body! ! ! ! ! ! ! ! ! ! ! ! ! !
