Exercise and diet - what's the danger?

One of the most common mistakes of fitness enthusiasts is considered to be the wrong diet for high physical exertion. And if we assume that most people in fitness classes see a way out associated with weight loss or with the correction (build-up) of problem parts of the body, then a starvation diet will lead to the opposite result or to its complete absence.

Are exercise and diet compatible?

Let's say you decided to speed up the process of getting rid of body fat and began to force physical activity and limit yourself in food (in fats and carbohydrates, but not in protein, because muscles will not grow without protein). What will happen? Almost all processes in the body are regulated by the endocrine system (special chemicals - hormones). Physical activity is stress for the body, for which the two hormones cortisol and adrenaline are responsible. In addition to the fact that cortisol affects the level of adrenaline, increasing its concentration under stress, it changes the metabolism.

In the normal state of the body, cortisol enhances the synthesis of glucose in the liver cells (creates energy stores), and in the cells of muscle tissue reduces the breakdown of glucose. In a state of chronic stress (exercise and malnutrition are stressful), cortisol levels remain high and the breakdown of glucose in muscle tissue begins. Lack of glucose causes an irresistible desire to eat something sweet, and you just decided to cut yourself in carbohydrates and fats (went on a rigid diet). The circle has closed, and the body has no choice but to start using up the reserves of fats, carbohydrates, and protein that it has accumulated in advance.

You thought: "Now the time has come to leave fat deposits!". But the body cannot be outsmarted by spending energy reserves, it seeks to create them again (from those miserable food components that you left in your diet). The body's defense reaction forces it to accumulate to a greater extent than it is spent (just in case). And as a result, it turns out that you not only did not lose, but also gained weight.

It is believed that the number of calories consumed by the body should be almost equal to the expenditure of these calories during exercise, and not less than the body needs to expend, while maintaining a healthy metabolism in your body at the same time.

It is for this reason that during physical activity, calculated for weight loss, the diet should correspond to the load regimen, and not add problems to the body.
