This article will help you calculate the number of calories you consume daily in four simple steps; in this way you will be able to calibrate your diet in a more correct and scientific way.
A precise calorie calculation must take into account various parameters such as gender, height, weight, body size, age and level of physical activity.
1) IMMEDIATE METHOD (inaccurate)
FOR SEDENTARY PEOPLE: weight (kg) x 31 = daily calorie requirement
FOR MODERATELY ACTIVE PEOPLE: weight (kg) x 38 = daily calorie requirement
FOR ACTIVE PEOPLE: weight (kg) x 44 = daily calorie requirement
LEGEND: moderately active at least three or four aerobic training sessions per week; active at least five aerobic training sessions
2) AUTOMATIC CALCULATION OF CALORIES IN 30 SECONDS
3) ACCURATE METHOD
- Calculation of the basal metabolic rate following the instructions given in the table
| BASAL METABOLISM | ||
| Age | DONNA | MAN |
| 18 - 29 | 14,7 x P + 496 | 15,3 x P + 679 |
| 30- 59 | 8,7 x P + 829 | 11,6 x P + 879 |
| 60 74 | 9,2 x P + 688 | 11,9 x P + 700 |
| > 74 | 9,8 x P + 624 | 8,4 x P + 819 |
| P = body loss expressed in kg | ||
- After estimating the basal metabolic rate (MB) for the calculation of the daily energy need it is necessary to evaluate the activity carried out in the 24 hours. It is possible to calculate this value with fast methods and with an acceptable degree of approximation:
1) define your level of physical activity (light, moderate, heavy) by referring to the following table
| LIGHT | MODERATE | INTENSE |
| employees administrative and managerial staff freelancers, technicians or similar |
housewives domestic collaborators sales staff tertiary workers |
workers in agriculture, livestock, forestry and fishing unskilled workers production and transport equipment operators |
2) physical activity desirable. Some people, in addition to the main activities, devote part of their time to optional motor activity, which is important to take into account when calculating calories.
We therefore introduce the concept of desirable physical activity understood as:
... the recommended activities for sedentary or non-sedentary subjects, for maintaining muscle and cardiovascular tone ....
a healthy adult engages in desirable physical activity if four or five times a week devotes at least 20 minutes to physical exercise of sufficient intensity to cause noticeable sweating
| Woman | Age | WORD | YES desirable activity | NO desirable activity |
÷ 18 59 |
light | 1,56 | 1,42 | |
| moderate | 1,64 | 1,56 | ||
| heavy | 1,82 | 1,73 | ||
| ÷ 60 74 | 1,56 | 1,44 | ||
| 75 ≥ | 1,56 | 1,37 |
| Man | Age | WORD | YES desirable activity | NO desirable activity |
÷ 18 59 |
light | 1,55 | 1,41 | |
| moderate | 1,78 | 1,70 | ||
| heavy | 2,10 | 2.01 | ||
| ÷ 60 74 | 1,51 | 1,40 | ||
| 75 ≥ | 1,51 | 1,33 |
- The basal metabolic rate multiplied by the LAF (taking into account any desirable activity) expresses the amount of daily calories needed to cope with energy expenditure. It is expressed in kcal / day:
CALORIE NEED (kcal / day) = MB x LAF
