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 Harris-Benedict formula used here is the original formula published in 1918 and 1919.
The Harris-Benedict formula for determining the BMR is defined as:
\(BMR\): The basal metabolic rate
\(height\): \(= height_{feet} + height_{inch}\)
\(weight\): The weight measured in pound
\(height_{feet}\): The first part of the height measured in feet. For example \({\color{rgb(230,179,255)} 5}\) in \({\color{rgb(230,179,255)} 5}\)'10''
\(height_{inch}\): The second part of the height measured in inch. For example \({\color{rgb(230,179,255)} 10}\) in 5'\({\color{rgb(230,179,255)} 10}\)''
\(age\): your age measured in years
The unit for BMR is: \(kilocalorie/day \text{ } (kcal/d)\)
