The Rest Metabolic Rate (RMR) is similar to the Basal Metabolic Rate, however it measures the calories that your body burns while at rest, which is usually a bit higher than the BMR.
This calculator uses the Katch-McArdle formula in combination with the Boer formula to determine your lean body mass (LBM).
Both the Katch-McArdle and the Cunningham formulas are more suitable for individuals whose muscle mass are significantly higher than average.
The Katch–McArdle formula for determining the RMR is defined as:
\(RMR\): The Lean Body Mass
\(height\): \(= height_{feet} + height_{inch}\)
\(weight\): the weight measured in pound(lbs)
\(height_{feet}\): 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'\({\color{rgb(230,179,255)} 10}\)''
The unit for RMR is: \(kilocalorie/day \text{ } (kcal/d)\)
