In 1919, American scientist Francis Benedict and his co-author, James Harris, published a paper on the basal metabolic rate — the amount of energy needed for a body at rest to function properly. In this paper, there was a formula that can help calculate the number of calories taking the weight, the height, the age, and the gender of a person into account.
Because life conditions have changed a lot since the paper of Benedict and Harris was published, in 1990, their formula was updated by a group of scientists including Mark Mifflin and St. Jeor. The basic principle is the same but the numbers have changed. At the moment, the Academy of Nutrition and Dietetics claims that this formula is the most accurate among others.
The Mifflin — St Jeor formula looks like this:
So, for a 30-year-old woman with a height of 170 cm and weight of 65 kg, the calculations of calories for the body to function normally at rest is the following:
(10 × 65) + (6.25 × 170) — (5 × 30) — 161 = 1,401.5
The formula also takes your physical activity into account, so you need to multiply your result by a certain number:
So, for a girl with the parameters mentioned above who runs a few times a week, the number of calories will be 1,401.5 × 1,375 = 1,927.06. However, if the girl exercises 6-7 times a week, her daily norm would be 1,401.5 × 1,725 = 2,417.6.
