📋Ringkasan
The BMR Calculator computes your Basal Metabolic Rate — the calories your body burns at complete rest just to keep you alive. It's the foundation for understanding your true daily energy needs.
What BMR represents and why it matters
Your BMR is the energy required for basic functions: breathing, circulation, cell repair, and maintaining body temperature. It accounts for roughly 60–70% of the calories most people burn daily.
Knowing your BMR is the starting point for any nutrition plan. Everything else — activity, exercise, digestion — is added on top to reach your total daily expenditure (TDEE).
Factors that raise BMR include more muscle mass, larger body size, younger age, and being male on average. This is why strength training, which builds muscle, can gently raise your resting burn.
Why BMR slows with age and dieting
BMR naturally declines with age, largely because muscle mass tends to decrease. This is one reason maintaining weight gets harder over the years unless activity and protein intake stay high.
Aggressive, prolonged dieting can also lower BMR as the body adapts to fewer calories — a phenomenon sometimes called 'metabolic adaptation'.
Preserving muscle through resistance training and adequate protein is the most effective way to keep your BMR from dropping faster than necessary.

🔢Rumus yang digunakan
Mifflin-St Jeor: Males = 10×weight + 6.25×height − 5×age + 5. Females = same − 161💡Contoh praktis
Example: Male, 30y, 75kg, 175cm
BMR ≈ 1,724 calories at rest. With moderate activity (×1.55), total needs rise to about 2,672 calories per day.
✅Tips penting
- •Build and maintain muscle with resistance training — it's the most reliable way to support your BMR.
- •Use BMR as the base, then add an activity factor to find the calories you actually need each day.
- •Don't eat at your BMR level to lose weight; that ignores all the energy you burn through daily movement.
⚠️Kesalahan umum yang harus dihindari
- ✗Confusing BMR (at rest) with TDEE (total daily burn) and under-eating as a result.
- ✗Assuming BMR is fixed — it changes with muscle mass, age, and prolonged dieting.
- ✗Expecting the formula to be exact; it's a solid estimate, not a precise measurement.
❓Pertanyaan yang sering diajukan
Q:What's the difference between BMR and TDEE?
A: BMR is the calories burned at complete rest. TDEE adds the energy from daily activity and exercise, and it's the number that reflects what you actually need to eat to maintain weight.
Q:Can I increase my BMR?
A: To a degree, yes. Building muscle through resistance training raises your resting burn, and staying active helps. Genetics, age, and body size also play major roles.
Q:Why does BMR decrease with age?
A: Mainly because muscle mass tends to decline with age. Since muscle burns more energy at rest than fat, losing it lowers your BMR over time.
Q:Should I eat at my BMR to lose weight?
A: No. Eating only your BMR ignores the calories you burn through daily activity, creating an excessive deficit. Base weight loss on your TDEE instead.
Q:How accurate is the BMR formula?
A: The Mifflin-St Jeor equation is one of the most accurate estimates available, but individual metabolism varies. Use it as a reliable starting point and adjust based on real-world results.
Q:Does dieting lower my BMR?
A: Prolonged, aggressive calorie restriction can reduce BMR as the body adapts. Moderate deficits and preserving muscle through protein and training help minimize this effect.
