This is abdominal fat. Abdominal fat is mainly visceral fat. When the intake of calories is greater than the consumption of calories, the excess calories will be converted into fat and temporarily stored in the abdomen. When the heat is insufficient, it can be burned quickly to provide energy. If a person consumes too many calories and too little for a long time, it is easy to cause abdominal obesity (central obesity).

The human abdomen is one of the most prone parts to accumulate fat.

Extended data:

Overeating, especially excessive intake of sugar, is one of the main factors of abdominal fat accumulation, so controlling the intake of fasting sugar and refined sugar is the best way to reduce abdomen.

At the same time, you can also eat olive oil and margarine to avoid excessive fat intake. Combined with regular physical exercise, it can effectively and quickly reduce the abdomen.

The increase of abdominal fat is also related to spleen deficiency, which can not clean up the "garbage" in the body-moisture. Once the spleen is too wet, it will damage the qi of spleen yang and temper, and it will not be able to convert food into nutrition. If it stays in water for a long time, it will become turbid and accumulate into fat.
