What Is Basal Metabolic Rate (BMR)?
Basal Metabolic Rate is the minimum number of calories your body burns over 24 hours purely to sustain its vital functions (breathing, heartbeat, cell renewal, body temperature regulation) without any movement. Our calculation uses the Mifflin-St Jeor formula, considered the most accurate in scientific literature.
Why Is BMR the Foundation of Weight Management?
Most of your daily calorie requirement (typically 60-75%) comes from your BMR. Your BMR is always the reference point when building a weight-loss or weight-gain plan; dropping far below it can slow your metabolism and lead to muscle loss.
How Can You Increase Your BMR?
As muscle mass increases so does BMR, because muscle tissue consumes more energy than fat tissue. People who train with resistance regularly see their basal metabolic rate rise over time. With the right nutrition combined with strength training, it is possible to speed up your metabolism in the long term.
