Research1 shows that there can be up to a 26% variance from the calculated BMR value. However, an average person eating an average diet will likely have the expected BMR value.

What is Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE)?
- BMR tells you how many calories your body uses to maintain basic functions like breathing and digestion while at rest.
- TDEE estimates how many calories you burn each day based on your activity level—sedentary, lightly active, moderately active, very active, or extra active.
Why it matters:
Your BMR is the foundation of your metabolism. Knowing your BMR and TDEE can help you make smarter decisions when it comes to weight management, fitness goals, and nutrition planning. Whether you’re looking to lose, maintain, or gain weight, this tool gives you the numbers you need to guide your journey.
Benefits of using this tool:
- Personalized Insights: Calculations based on your body and lifestyle.
- Smart Goal Setting: Understand how many calories you actually need.
- All Activity Levels: Instantly see your TDEE for each level of daily activity.
Knowing your BMR and TDEE is essential for creating a personalized diet or fitness plan. Whether you’re looking to lose weight or build muscle, start with the numbers that matter.
