How Does The Body Know Where To Store FAT?


We all have fat in our bodies, but each body stores fat in different places. Some people have fat in the abdomen, while others have fat in their thighs, hips and other areas. We can’t do anything, we don’t have control over where our bodies store fat.

Good fat plays an important role, not only in providing energy for the body but also in regulating body temperature, hormone production, reducing inflammation, … But the following article will not pay The answer to the question of good and bad fat is an answer to the question: “How does the body decide where to store fat?”.

How Does The Body Know Where To Store FAT?

Digestive system:

To understand how the body stores and distributes fats, we must first briefly understand how food is digested in the body. The digestive process begins as we put food in the mouth, where it is mechanically absorbed when we chew and then is chemically digested by the amylase enzyme in saliva. When we swallow, the digestive process will automatically. Food that we eat reaches our stomach through the esophagus, where it is disturbed, becoming smaller pieces that mix with acid and digestive juices.

This partially digested food is taken into the small intestine, where most digestive processes take place. Pancreatic juice, bile (produced by the liver in a human body) and intestinal digestive juices will be mixed into this pre-digested food portion and break down complex nutrients into simpler forms.

Proteins are broken down into amino acids, and the fat is broken down into fatty acids and carbohydrates, decomposed into simple sugars or monosaccharides, such as glucose. The digested nutrients from the food are then absorbed into the blood through the walls of the small intestine, while the waste is transferred to the large intestine to form and excrete feces.

How is fat formed?

When nutrients broken down in the small intestine are absorbed into our blood, our blood glucose levels (sugar) increase. The pancreas, which regularly monitors blood sugar and releases a hormone called insulin when it senses an increase in sugar. Insulin is published in the blood to signal muscle cells and other cells in our body to absorb glucose from the blood to reduce blood sugar levels. These cells receive the message, thanks to insulin receptors “wrapped” in the cell membrane and taking glucose from the blood to get energy.

When the cells have absorbed the energy they need, insulin signals the liver to absorb glucose store it as a starch called glycogen. However, when glycogen is sufficiently stored, lipid production is stimulated.

Where is fat stored?

Fat is stored in fat cells, cells of a loose connective tissue are called adipose tissue. A fat cell is like a small package in which a fat drop can be stored.

Adipose tissue, it will found under the skin of the human body, around the internal organs, in the bone marrow, and the breast tissue. It’s found in different locations of the human body. Subcutaneous adipose tissue is found in the lower abdomen, hips, thighs, etc. The visceral fat is located in the stomach, around essential organs of the body.

Fat distribution

We often hear phrases to describe body shapes like “apples” or “pears.” “Apple” body types store fat in the center of the body, while “pear” types store it in the lower part of the body. Find out why different people store fat in different areas of their bodies.

We have to consider two points when discussing body fat distribution: the number of fat cells in a given area and the level of their fat storage. These two points determine the total mass and area of ​​adipose tissue in our body. The available evidence does not show the reason for local replication of fat cells but may give some idea of ​​the level of storage. Therefore, it can be safely said that the difference in regional fat mass is due to the difference in the level of fat storage in these cells.

The difference between men and women

Steroid hormones play a huge role (human beings) in this process. Therefore, the excretion of various steroid hormones and the density of receptors in the regions will determine the distribution of fat mass. The gender-based difference is that women have more fat under the skin than men, while men have higher rates of visceral fat. Besides, women have enlarged adipose tissue in the hips and thighs. Fat accumulation in this area is also the result of a ready reception caused by the higher lipoproteins lipase activity in this region due to female sex steroid hormones. Because of these hormones, women store most of the fat in the lower part of the body, while men store it evenly throughout the body, mostly in the center.

On the other hand, women tend to redistribute fat in the abdomen and increase visceral fat after menopause, probably due to reduced estrogen levels (female sex hormones). Women before menopause are more likely to help their organs limit fat accumulation to a certain extent. Men who accumulate fat in this area are almost the same as in other is partly explained by the fact that women’s adipose tissue has more “space.”


Long-term chronic stress is a significant factor in deciding where to store fat, regardless of gender. Exposure to stress releases the stress hormone in the form of cortisol, which increases the amount of fat stored in the abdomen. Everyone faces pressure, but not everyone responds by secreting the same level of cortisol. Therefore, people who release this hormone higher will accumulate more belly fat.

Other factors

Genetics also plays a huge role in determining our ability to respond to stress, metabolism, and insulin sensitivity, etc. They all contribute to our body’s decision to store fat… Factors such as lifestyle and age also significantly affect the level of belly fat. Also, alcohol, smoking, lack of sleep and less exercise also make the belly accumulate more fat.

Excess fat, although stored in any area, leads to many health problems, but fat stored in the center of the body poses more health risks in the lower body. Therefore, visceral fat is more dangerous than subcutaneous fat. Obesity is associated with the risk of cardiovascular disease, diabetes, insulin resistance, and other serious side effects.

Whether you own an “apple” or “pear” body, proper nutrition, exercise, and a healthy lifestyle are all critical factors to keep in shape.
