Understanding BMR & TDEE

What is BMR?

Basal Metabolic Rate is the number of calories your body needs to perform basic life-sustaining functions at rest.

What is TDEE?

Total Daily Energy Expenditure includes BMR plus calories burned through physical activity and digestion.

Weight Loss

To lose weight, consume 500 calories less than your TDEE daily to lose about 1 pound per week.

Weight Gain

To gain weight, consume 500 calories more than your TDEE daily to gain about 1 pound per week.

BMR & Calorie FAQs

What's the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is calories burned at complete rest. TDEE (Total Daily Energy Expenditure) is BMR plus calories burned through activity and digestion.

How accurate is the BMR calculation?

The Mifflin-St Jeor equation used here is about 80-90% accurate for most people. Individual variations in metabolism can affect actual calorie needs.

Why do men have higher BMR than women?

Men typically have more muscle mass and less body fat than women of the same weight and height, resulting in a higher metabolic rate.

How does age affect BMR?

BMR decreases with age due to loss of muscle mass and changes in hormonal activity. This is why it's harder to maintain weight as you get older.

Can I increase my BMR?

Yes! Building muscle through strength training, staying active, eating enough protein, and getting adequate sleep can all help increase your metabolic rate.
