The Basal Metabolic Rate (BMR) is an estimation of the amount of a person's energy expenditure while at rest, in a thermal neutral zone (\(21^\circ C\) or \(69^\circ F\)) and in the absorptive state (normally happens after 12 hours of fasting).
BMR is a more accurate measure of your metabolism at complete rest, which is normally a bit lower than your RMR.
The Mifflin and St Jeor formula used here is the revised version of the original Harris-Benedict formula by Mifflin and St. Jeor back in 1990.
The Mifflin and St Jeor formula for determining the BMR is defined as:
\(BMR\): The basal metabolic rate
\(weight\): The weight measured in kilogram
\(height\): The height measured in centimeter
\(age\): your age measured in years
The unit for BMR is: \(kilocalorie/day \text{ } (kcal/d)\)
