The number of calories needed for each person can be calculated individually. They vary widely according to gender, age, body weight, and available comorbidities. Thus, if the norm is 2000 kcal per day, then for some you will need a little more, while for others they should be less.
In cases where a person wants to know how much food he needs per day, it will be important to consider the basal metabolism, physical activity and the heat effect of food.
By basal metabolic rate is meant the amount of energy the body needs when at rest. It is needed to maintain the heart, lungs, eyelids and eyelids and maintain optimal body temperature.
And the heat effect of food means the amount of energy that the body uses to digest it.
Thus, not very active people need on average between 2000 and 2600 kcal, as those with an average age - between 2400 and 2600, from 31 to 50 years - 2200 to 2400 kcal, and after 50 years of age between 2000 and 2200 kcal per day.
The active man differs from the general scheme, as he needs 2200 to 2800 kcal per day.
According to a study from the University of Washington, caloric needs can be easily calculated. They believe that for every kilogram of body weight you need 18 kcal, and only if physical activity is increased.
Otherwise, no more than 15 kcal per kilogram of weight is needed. 13 kcal are recommended for people over 55, and 10 kcal for those with a sedentary lifestyle.
Thus, an active lady weighing about 60 kg needs about 1100 - 1200 kcal, but if there is no physical passivity, then she does not need more than 900-1000 kcal.
For overweight men, no more than 1200 and 1600 kcal per day are provided.
