Basal Metabolic Rate (BMR)

Definition

BMR refers to the number of calories required to keep your body functioning while at rest. In other words, it's the amount of energy used by the body just for basic functions like breathing and maintaining heartbeat.

Analogy

Imagine BMR as being akin to paying bills for basic utilities in an apartment - even if no one lives there or uses any appliances, there are still costs associated with keeping everything running smoothly (like heating or cooling).

Thermogenesis: This is the process of heat production in organisms, often related to metabolic reactions. Think of it as a furnace that keeps your house warm during winter.

Caloric Intake: The number of calories a person takes in from food and drink. It's like filling up your car with gas - the more you put in, the longer it can run (or the more weight you might gain).
