📘 What Is BMR and Why It Matters

BMR stands for Basal Metabolic Rate. It’s the number of calories your body needs just to keep you alive – breathing, heart beating, brain working. Even if you lie in bed all day, you still burn these calories.

For example, if your BMR is 1,500 calories and you are sedentary, you need about 1,800 calories daily to stay the same weight.

• Sedentary (little or no exercise)
• Lightly active (1-3 days/week)
• Moderately active (4-5 days/week)
• Very active (daily intense exercise)
• Extra active (physical job + intense training)

🧮 BMR Formula Explained (Mifflin-St Jeor)

Most experts use the Mifflin-St Jeor equation. It’s the most accurate for most people. Here it is:

Example: A 35‑year‑old woman, 65 kg (143 lbs), 165 cm (5’5”) → BMR = (10×65) + (6.25×165) – (5×35) – 161 = 1,383 calories per day. That’s how many calories she burns at rest. Our bmr formula with example usa makes it easy to understand.

📊 BMR vs TDEE – Important Difference

BMR is your resting calorie burn. TDEE (Total Daily Energy Expenditure) includes all activities – walking, cooking, exercise. To lose weight, eat 300–500 calories below your TDEE. To gain muscle, eat above TDEE.

Our bmr vs tdee calculator difference usa tool shows both numbers. Use the activity level multiplier table below:

Activity Level	Multiplier	Example (BMR 1,400)
Sedentary (little exercise)	1.2	1,680 calories/day
Lightly active (1-3 days/week)	1.375	1,925 cal/day
Moderately active (4-5 days/week)	1.55	2,170 cal/day
Very active (daily intense)	1.725	2,415 cal/day
