There are also types of fat

Obesity is defined as a state in which excess body fat is accumulated in our body, and there are two types of body fat.

Subcutaneous fat literally means fat under the skin.

Visceral fat is the fat located between the organs of the body.

For example, even if body fat is the same 40%, the effect on health varies greatly depending on whether the area where this is accumulated is subcutaneous or internal.

1. Subcutaneous fat is not a problem!!

When comparing whether or not you eat rice, the subcutaneous fat is thicker in the non-eating side. In other words, it is easy to become obese if the next meal is large after starving or skipping meals for several days to lose weight. Even if you eat the same amount, it is better not to eat a lot at once, but to divide it into small amounts and eat several times (4-6 times).

Subcutaneous fat literally refers to the fat accumulated under the skin, and this applies to people who have an exceptionally thick belly skin even if they have a belly of the same circumference.

If you gain weight during your growth phase, it is often subcutaneous fat type. (Compared to this, adults in their 30s and older have a lot of visceral fat type.) Teenagers with stomachs can be considered subcutaneous fat type. In fact, this subcutaneous fat may be a cosmetic problem, but it is not a big problem in terms of health, such as causing adult diseases. However, since it is a problem cosmetically, it is also the part where people try to lose weight.

2. Then, what about belly (visceral) fat?

There are many cases where you can not control the weight that has been growing together for several decades, and as you become middle-aged. In particular, most people focus on the belly fat that swells day by day.

Arms and legs keep getting thinner, but only the belly is bulging, which is a typical middle-aged body type. Do you know that abdominal obesity is the biggest cause of various adult diseases as well as not looking good???

Belly (visceral) fat refers to the fat accumulated between the organs of the human body.

This visceral fat is very likely to suffer from various adult diseases such as diabetes, high blood pressure, and hyperlipidemia. Fat cells around the intestines are much easier to metabolize in the body than subcutaneous fat. The reason is that lipoprotein lipase (lipoprotein lipase), which breaks down accumulated fat into neutral fat and stores the neutral fat in fat cells, is very active in the fat of the abdomen. Therefore, fat in the abdomen easily flows into the blood and raises the level of cholesterol in the blood.

Looking at the process by which visceral abdominal obesity develops into an adult disease, the adipocytes in the abdominal cavity have the property of easily accumulating and decomposing fat, secreting a lot of fatty acids into the blood. When fatty acids are secreted into the blood, the first reaction is that the effect of insulin in the muscle or liver is reduced. Insulin plays a role in bringing glucose, an energy source, into each cell in the body. Therefore, when blood fatty acids are elevated, cells accept fat instead of glucose, and glucose influx is hindered, which is medically called insulin resistance.

When glucose is not consumed due to insulin resistance, blood glucose rises. This stimulates the beta cells of the pancreas to promote insulin secretion and increase the level of insulin in the blood. This is called hyperinsulinemia. When the level of insulin in the blood increases, the excretion of salt from the kidneys decreases and accumulates in the body, and the sympathetic nerve is stimulated to accelerate the heartbeat or constrict blood vessels, resulting in hypertension.

Non-insulin dependent diabetes mellitus develops when the beta cells of the pancreas cannot handle the insulin secretion function when the blood glucose level continues to rise. In addition, hyperinsulinemia causes dyslipidemia, which increases the concentration of triglycerides in the blood and decreases the concentration of beneficial cholesterol (HDL cholesterol) in the human body. These work in combination to cause arteriosclerosis. When arteriosclerosis occurs, it causes angina pectoris and myocardial infarction in the coronary arteries and causes scary complications such as stroke (stroke) in the cerebral arteries.

ah!!! The above is a bit difficult. However, because it is an important content that is directly related to human life... *^0^*

There is something difficult for people to judge about abdominal obesity. That is, abdominal obesity is judged only with the thickness of the belly fat. In other words, if you hold your stomach with your hands and get a lot of it, it is called abdominal obesity, which is just subcutaneous fat. Therefore, it is more important to consider the visceral fat distributed between the organs of the abdomen and organs.

Also, if the stomach is hard, it is easy to think of it as muscle, but this is only because the connective tissue that connects the fat tissue is developed and feels solid, not muscle.

It is true that abdominal obesity and poop belly are different from each other. Abdominal obesity is the upper belly around the navel under the pituitary gland, and poop belly is the accumulation of feces in the large intestine or the bulging lower abdomen due to gas. Therefore, it is not an accurate judgment to misunderstand a pot belly as abdominal obesity or to think that there is no problem because there is no pot belly.

A way to accurately distinguish between subcutaneous and visceral fat is to use computed tomography. In other words, the ratio of the area (S) of visceral fat (V) and subcutaneous fat is obtained, and if the V/S ratio is 0.4 or more, it is called visceral fat-type obesity, and if it is less than 0.4, it is called subcutaneous fat-type obesity.

However, since special equipment is required to use this method, it is difficult for ordinary people to use it easily. So, simply divide the waist circumference by the hip circumference and use the ratio to determine whether or not you have abdominal obesity.
