Fat Gain – Function, Task & Diseases

Fat gain

Fat accumulation describes the accumulation and multiplication of fat cells in the human body. It is a basic function of the metabolism and has evolutionary biological backgrounds that only become problematic with modern diets.

What is fat gain?

The accumulation of fat in the human body is referred to as fat accumulation. Fat is a macronutrient, i.e. a nutrient that must be ingested in comparatively large quantities. However, it is recommended not to consume more fat than protein or carbohydrates , which has made modern diets significantly more difficult.

Ingested fat is stored by the body as a readily available source of energy for times when food intake is low. This is due to evolutionary biology: In earlier times, fat was not as readily available as it is today, so there were no problems with excessive fat intake.

If the diet was scarce, the stored fat cells could be quickly converted into energy through fat reduction if no carbohydrates were available. If the fat build-up has gotten out of control, the same only happens today with conscious and planned sport.

function & task

In addition to securing the energy supply in periods of low nutrition, the accumulation of fat also has a protective function for internal organs and certain parts of the body. This can be seen from where fat build-up takes place at all. 

Fat accumulates very quickly on the internal organs, such as the heart and the vessels around it – even on those organs that could be affected by bumps and blows and for which there is a certain risk of injury. In order to cushion this, the body first accumulates fat cells in internal organs when fat is built up. Then belly , legs , buttocks and breasts follow .

Changes can also often be seen on the chin and neck as well as on the face due to increased fat build-up. These are also parts of the body where injuries from fighting and from everyday human life were likely long before modernity.

The accumulation of fat also serves to repair damage to blood vessels inside the body. Small cracks are filled with a plug of different fats, but this can lead to problems ( arteriosclerosis ) in the long term. This is another reason why fat should not be consumed in excessive amounts.

In a healthy sense, the accumulation of fat in the body also serves to provide lubricants for many functions of the internal organs. Therefore, it should not be completely dispensed with in the diet, since the body cannot reproduce it itself.

Fat is used as a lubricant in the body by individual cells and entire organs, but is still required in comparatively small amounts compared to proteins or carbohydrates.

Fat cells are also good at storing toxins and getting them out of reach before they do any harm. If they cannot be excreted immediately, the body needs an “intermediate store” where they do not damage internal organs. The breakdown of fat creates fat cells, which are ideally suited for this – if the fat cells are broken down, however, stored waste products are also released again and must inevitably be excreted.

Diseases & Ailments

The biggest and at the same time the most modern problem of fat accumulation in humans is obesity . There are a number of different fats, all of which are necessary, but they are only healthy in the right amounts in the diet. The modern diet often contains just the fats that people take in in sufficient quantities anyway and of which they now get too many. 

Because the human body and how it works still assumes that a high-fat diet is a short-lived good period. So you store every gram of fat you eat and use it to build fat. The more fat you consume, the greater the risk of gaining weight – especially if you lead a sedentary lifestyle.

A pathological consequence of excessive fat accumulation with increasing weight is obesity . The term stands for morbid obesity. A BMI of 30 or more is generally referred to as obesity. This puts a strain on the internal organs and especially the circulatory system, can lead to serious illnesses as long-term consequences, and being overweight itself puts a heavy strain on the joints of the musculoskeletal system even at an early stage .

Excessive fat accumulation or obesity can result from improper nutrition, but also from taking medication or from congenital metabolic diseases . The latter causes an abnormal build-up of fat, so that those affected have to pay even more attention to diet and sufficient exercise than healthy people.

When taking medication, the metabolism can also change in such a way that fat loss increases sharply with the same diet. Or the drug causes an increased food intake and thus leads to an increase in fat breakdown activity. However, in these cases one can prepare for the increase in fat loss and try to counteract this with appropriate nutrition and exercise. A conversation with the doctor opens up further possibilities.

Fat accumulation is basically a healthy and normal mechanism of the body, but it can quickly become pathological if too many new fat cells are built up too quickly. Short-term consequence is obesity, long-term consequences can be several serious illnesses.
