Many diets are based on the action of so-called "fat burning" products. However, you will rarely find a detailed explanation of exactly how they destroy fat. How is the formation of adipose tissue in the body, what affects its volume and can products "burn fat"?

What is fat?

Fat, or adipose tissue of the body, is not at all an unpleasant excess that must be gotten rid of. It performs a number of important functions in the body.

Adipose tissue consists of large cells - adipocytes and connective tissue fibers. It comes in two varieties - white and brown. White fat cells play a leading role in energy storage. The main task of brown fat cells is heat production, and babies need them more so that they do not freeze. In adults, brown adipose tissue is present in small amounts between the shoulder blades, near the kidneys and thyroid gland.

Why does the body have fat?

Adipose tissue does not just add volume to the body. It performs several very important functions:

  • Part of the fat in the body is located around the internal organs, it is necessary for their support and protection. For example, the eyeball, kidneys and some other organs are surrounded by fatty tissue.
  • Part of adipose tissue is under the skin, as well as in the omentum. This is our strategic reserve of energy, which is used as needed.
  • A very important function of adipose tissue is thermoregulation: subcutaneous fat prevents us from freezing quickly.
  • Also, adipose tissue synthesizes hormones, for example, leptin and estrogens. It is precisely because of the activation of the production of female hormones that fat men with a beer belly often note a decrease in potency.
How much fat tissue should be in the body?

Of course, it all depends on what goal you set for yourself. If you just want to look good and have a beautiful figure, then the percentage of fat in a man's body should be about 20, for women - around 30.

True, if you want to show off "cubes" on the press, then the percentage of fat should be in the region of 10-12. Athletes who participate in competitions build muscle mass and bring their body fat percentage to 7. A figure below 5% is life-threatening.

Is it possible to reduce the number of fat cells?

Scientists have established that the number of fat cells in an adult's body cannot be reduced. It changes in children and adolescents and continues to increase until about 20 years of age. Further, the number of fat cells remains constant, only their size changes.

Scientists from the largest Swedish Karolinska Institute counted the number of fat cells in 20 people suffering from obesity. They underwent gastric bypass surgery, weight loss was up to 18%. At the same time, the number of adipocytes remained unchanged. So try not to push children when they refuse to eat. And then in adulthood it will be easier for them to fight with excess weight.

How does the volume of subcutaneous fat decrease?

Our volumes depend on how large fat cells are adipocytes. Inside the adipocyte is a fat drop, which can greatly increase in volume. And as a result, compared to the initial size, the fat cell can increase almost 30 times!


Thus, in order to reduce the volume of adipose tissue, one must try to reduce the volume of adipocytes, "bloat" these cells. And prevent the accumulation of new fat droplets in them.

What affects the volume of fat cells in adipose tissue?

Sometimes you can hear that the main enemy of our slimness is insulin. In fact, insulin is a vital hormone that fights excess glucose. But the mechanism of fat synthesis is involved.


How does this happen? The main task of insulin is to prevent sugar levels from rising. To do this, it prevents the breakdown of fats so that glucose is used as an energy source. Excess glucose is used by insulin in the form of... fat.

And the level of insulin in the blood is directly regulated by the amount of carbohydrates that you get with food. It turns out that there are no fat-burning products in their pure form. But there are products that increase or decrease the level of insulin, and thereby regulate the rate of reduction in the volume of adipose tissue.

What foods affect the level of insulin production?

Insulin is a hormone whose main task is to reduce the glucose content in the blood. At the same time, the volume of adipose tissue increases. If the insulin level is reduced with the help of food, then the weight loss process will go faster.

It is important to consider several indicators here:

  • Glycemic index of the product. If this indicator is high, it means that when using the product, the level of sugar (and insulin!) in the blood rises quickly.
  • Glycemic load. This indicator characterizes how a portion of the product will affect the body. The load is calculated according to the formula:

(GI of the product / 100) x carbohydrate content in a portion

GI - glycemic index


Low GN is considered up to 11, medium - from 11 to 19, high - from 20.

Insulin index of the product. This indicator indicates the insulin response to the use of the product. It is not always equal to the glycemic index, paradoxes also occur. If the GI and II of white bread are practically equal (101 and 100), then the GI of eggs is 0, and the II is 30. When preparing a diet for weight loss, we recommend that you consult the tables.
