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:
$$RMR$$ $$=$$ $$370$$ $$+$$ $$21.6$$ $$\times$$ $$LBM_{Boer}$$
$$RMR$$: 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: $$kilocalorie/day \text{ } (kcal/d)$$
