Estimated energy requirement for a healthy person, how to calculate.

The estimated energy requiment (EER) represent the average dietary intake that will maintain the body in a balance, according to the specific gender, age, weight, height and physical activity (PA) level.

To sustain a healthy active life, we all need a certain amount of calories, but not too many because it will lead to obesity. Remember all excesses are wrong and they result in weight gain and other problems.

To calculate your EER, select the appropiate equation for your gender:

For men 19 years and older:

EER = (662) - (9.53 x Age) + PA x (15.91 x Weight + 593.6 x Height)

For women 19 years and older:

EER = (354) - (6.91 x Age) + PA x (9.36 x Weight + 726 x Height)

Insert units as follows:

Age = Years

Weight = Kilograms

Height = meters

PA (Physical activity factor) = as shown in the table below

An example of calculation

Lets estimate the energy requirement for an active 35 year old female who is 1.70 mts and weighs 57 kgs.

First, using the table, we define that the PA factor will be 1.27, now, lets insert the data on the specific equation:

EER = 354 - (6.91 x 35) + 1.27 x (9.36 x 57 + 726 x 1.70)

EER = 354 - (6.91 x 35) + 1.27 x (533.52 + 1234.20)

EER = 354 - (6.91 x 35) + 1.27 x (1767.72)

EER = 354 - 241.9 + 2245

EER = 2357 calories/day.
