Before you start making the right diet, you should determine how much energy a particular person needs to maintain the body in a normal state throughout the day. This question is purely individual, and it is based on the calorie corridor, which can be calculated in a simple mathematical way.
Energy in our body is generated by the consumption of nutrients, there are no other ways for its formation. But the expenditure of energy on the processes of life in different people is different. It all depends on many factors, including: lifestyle, eating habits, as well as the individual degree of physical activity. All this underlies how to calculate calorie value most accurately. This is precisely the reason why, with the same diet, someone is losing weight, while someone, on the contrary, is gaining weight.
Traditionally, it is calories that have been accepted as the unit of energy metabolism. This is a very small value, it corresponds to the amount of energy that is needed to heat one milliliter of water by one degree Celsius. For greater convenience, the body’s energy processes are measured in kilocalories, with 1,000 calories in one kilocalorie.
So, let's try to figure out how excess weight is accumulated and how many calories you need to cut your daily diet in order to lose it. If you need to reduce your weight, it is important to know a few nuances so as not to harm your health. Namely: how much energy the body will need for normal operation, as well as how much it actually enters during meals. The range between the upper and lower limits of the number of calories that are consumed during the day is called the "calorie corridor".
This term was adopted in order to simultaneously maintain the body in a working and active state, but at the same time control body weight. Thus, we calculate what calories per day are required for the stable operation of our body. The quantity and quality of trace elements that we need daily depends on age and weight category. As a rule, the calorie corridor is calculated taking into account age, body weight, energy and energy expenditure. These data are most often compiled by a nutritionist individually.
In addition to the calculations for the total energy consumption, it is also important to make an adjustment for the level of physical daily activity. The intensity of the basal metabolism must be multiplied by the coefficient of the level of physical activity. If the activity is low, then the coefficient will be 1.1, if moderate - 1.3, and if high - will be 1.5. Of course, the calculations presented by us are rather cumbersome, and without a calculator it will be quite difficult to make calculations, however, they most accurately display the calorie corridor, and, in addition, the amount of energy consumed by the body during the day, so it is best to use them.
