Understanding TDEE and BMR
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic life-sustaining functions. Even if you stayed in bed all day, your body would still burn these calories for breathing, blood circulation, and cell production.
The Role of TDEE
Total Daily Energy Expenditure (TDEE) is an estimation of how many calories you burn per day when exercise is taken into account. It is calculated by first figuring out your BMR, then multiplying that value by an activity multiplier.
Mifflin-St Jeor Equation
CalcFind uses the Mifflin-St Jeor equation, currently considered the most accurate formula for predicting BMR in healthy adults.
Sustainability is Key
While calorie counting is a powerful tool, it's important to remember that these are estimates. Factors like muscle mass, hormonal health, and metabolic adaptation play a role. We recommend starting with these numbers and adjusting based on your actual progress over 2-4 weeks.
Consistency in activity and tracking provides the best data for long-term health management.
