Definition
Resting Metabolic Rate: the number of calories your body burns just existing in a chair, doing nothing but maintaining life functions. It's the baseline caloric cost of your meat prison before you add actual activity, typically measured first thing in the morning.
Example Usage
Her RMR test revealed she burned 1,400 calories daily at rest, making her diet planning less guesswork and more math.
Origin
From metabolic research and indirect calorimetry measurement techniques
Fun Fact
RMR accounts for 60-75% of total daily energy expenditure in sedentary people, meaning most calories are burned doing absolutely nothing.
