Frequently Asked Questions

What is BMR?

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest to maintain vital functions.

How is BMR calculated?

We use the Mifflin-St Jeor equation, considered the most accurate for most people.

What is the difference between BMR and TDEE?

BMR is calories at rest. TDEE (Total Daily Energy Expenditure) includes activity and exercise calories.

How can I increase my BMR?

Build muscle through strength training, stay hydrated, get adequate sleep, and eat sufficient protein.

Does age affect BMR?

Yes. BMR typically decreases with age due to muscle loss and metabolic changes.

Do men have higher BMR than women?

Generally yes, due to greater muscle mass and larger body size on average.

How accurate is BMR calculation?

Formulas provide estimates within 10% for most people. Individual metabolism varies.

Should I eat below my BMR to lose weight?

No. Eating below BMR long-term can slow metabolism. Create moderate deficits from TDEE instead.

What factors affect BMR?

Age, sex, weight, height, muscle mass, genetics, hormones, and health conditions all influence BMR.

How do I use BMR for weight loss?

Calculate TDEE from BMR, then consume 300-500 calories below TDEE for sustainable weight loss.
