BMR: Your Metabolism's Secret Weapon
Ever Wonder Why?
Some people seem to eat anything and not gain weight, while others struggle?
Your Basal Metabolic Rate (BMR) holds a key answer.
What is BMR and why is it important?
BMR is the minimum calories your body needs to function at rest.
It powers essential processes like breathing, circulation, and cell production.
How do you calculate your Basal Metabolic Rate?
BMR is estimated using formulas that factor in your age, biological sex, weight, and heigh
These equations provide a personalized baseline for your energy needs.
Which BMR formula is the most accurate?
The Mifflin-St Jeor equation is currently considered the most accurate BMR prediction form
It's widely used for the general population to estimate calorie requirements.
Let's Calculate: Mifflin-St Jeor
Example: 30yo male, 70kg, 175cm. Formula: (10*W) + (6.25*H) - (5*A) + 5.
Breaking Down the Numbers
BMR = (10 * 70) + (6.25 * 175) - (5 * 30) + 5.
This simplifies to 700 + 1093.75 - 150 + 5.
Your Baseline Energy
This individual's estimated BMR is 1648.75 calories per day.
This is the energy needed just to keep their body running at rest.
60-75%
Your BMR accounts for the majority of your daily calorie expenditure.
What is a healthy BMR for my age and sex?
There's no single 'healthy' BMR number. It's unique to your body composition.
Factors like muscle mass and age significantly influence your rate.
How does BMR relate to weight loss and gain?
Knowing your BMR helps you set accurate calorie targets for your goals.
Eat above your BMR (and activity) to gain, or below to lose weight.
What is the difference between BMR and TDEE?
BMR is just resting calories. TDEE (Total Daily Energy Expenditure) includes BMR.
TDEE also accounts for calories burned from activity.
