BMR Vs RMR - What’s The Difference?

BMR and RMR are both about how many calories your body uses when you're totally relaxed, like sleeping or sitting still.

BMR stands for Basal Metabolic Rate, which is the number of calories your body needs just to keep going while you're completely at rest. It's like the smallest engine in a car, it keeps everything running even when nothing else is happening.

RMR stands for Resting Metabolic Rate, and it’s similar to BMR, but it includes some extra things like sitting up or thinking about your favorite toy. So RMR is like the slightly bigger engine that helps you stay awake and ready for fun, just not running around.

Imagine you're a robot. Your BMR would be how many batteries you need if you were just lying still in your charging spot, while your RMR would be what you need if you were sitting up watching TV or playing with blocks.

Most of the time, people use RMR because it’s easier to measure and more useful for everyday life, like when you're planning how many snacks to eat before bedtime.
