ENERGY NEEDS

DAILY ENERGY NEEDS

Our body needs energy all the time.

In one day the amount of calories that our body consumes when we rest is called Basal Metabolic Rate (BMR). The BMR are the calories needed to mantain body temperature and the function of vital organs like the heart, lungs, brain, etc.

The BMR is different depending on the age, sex, weight and enviromental temperature of a person. As a result, everybody has a different BMR, but in general is higher when a person is growing and lower when the person is older or has low body mass.

Most people do not rest all day, they usually perform different activities so their energy needs vary depending on these activities. Based on the activity of a person, additional calories must be added to BMR.

FORMULA OF BMR

MEN:

BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)

WOMEN:

BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
