How do I calculate BMR at home accurately?

You can calculate BMR using the Mifflin-St Jeor equation. For men: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5. For women: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 161. Use the WellVedis BMR Calculator for instant, accurate results.

What is the difference between BMR and TDEE?

BMR is the calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through daily activities and exercise. TDEE is typically 20-40% higher than BMR depending on your activity level.

Does BMR increase with muscle mass?

Yes, BMR directly increases with muscle mass. Each pound of muscle burns approximately 6 calories per day at rest, while fat burns only 2 calories per day. This is why individuals with higher muscle-to-fat ratios have higher BMRs.

What factors affect my BMR the most?

The primary factors affecting BMR are: age, gender, body composition (muscle vs. fat), genetics, hormonal status, and medical conditions. Nutrition, exercise habits, and sleep quality also significantly influence metabolic rate over time.

Calculate Your BMR by Age, Gender & Activity Level

Use the WellVedis BMR Calculator to estimate how many calories your body burns at rest and during activity. This tool adapts to your age, gender, weight, and fitness level to provide accurate daily energy needs. Whether your goal is fat loss, muscle gain, or weight maintenance, knowing your BMR is the foundation for effective nutrition planning.

What is Basal Metabolic Rate (BMR)?

BMR measures the minimum calories your body needs to sustain essential life functions — breathing, circulation, and cell repair. It represents how much energy your body uses at rest.

Why Knowing Your BMR Matters

Understanding your BMR helps tailor your diet and workouts. A higher BMR means your body burns calories faster. If you have a slow metabolism, adjusting your activity level or muscle mass can improve it over time.

How the WellVedis BMR Calculator Works

This tool uses the Mifflin-St Jeor Equation — one of the most accurate BMR formulas:

Men: BMR = 10 × weight + 6.25 × height − 5 × age + 5
Women: BMR = 10 × weight + 6.25 × height − 5 × age − 161

It then multiplies your BMR by your activity level to estimate your Total Daily Energy Expenditure (TDEE).

Factors That Influence BMR

🧬 Age: Metabolism slows naturally with age.
⚖️ Body composition: More muscle increases BMR.
🚻 Gender: Men usually have higher BMR due to muscle mass.
💪 Activity: Exercise boosts metabolic rate over time.

Practical Uses of BMR

You can use your BMR to:

Plan calorie intake for weight loss or muscle gain.
Track metabolic health with tools like VO₂ Max Estimator and Body Fat Calculator.
Adjust your diet for improved energy and recovery.
