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 Roza and Shizgal formula used here is the revised version of the original Harris-Benedict formula by Roza and Shizgal back in 1984.

The Roza and Shizgal formula for determining the BMR is defined as:

= h e i g h t_{f e e t} + h e i g h t_{i n c h}

w e i g h t

: The weight measured in pound

h e i g h t_{f e e t}

: The first part of the height measured in feet. For example

h e i g h t_{i n c h}

: The second part of the height measured in inch. For example

The unit for BMR is:

k i l o c a l o r i e / d a y (k c a l / d)
