What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate, or BMR, is the specific amount of energy (measured in calories) that your body requires to perform its most basic, life-sustaining functions while you are at rest. Even when you are sleeping or sitting perfectly still, your body is hard at work.

The Variables That Influence Metabolism

Your BMR is unique to you and is influenced by several biological factors. Age is a major component; as we get older, muscle mass tends to decrease, which can slow down the metabolic rate. Gender also plays a role, as men typically have higher muscle mass.

BMR: The Foundation of Success

Understanding your BMR is the vital first step in calculating your Total Daily Energy Expenditure (TDEE). Once you know your baseline resting calories, you can add your physical activity multipliers to find out exactly how much fuel you need.
