What is the difference between BMR and TDEE?

BMR is the calories your body burns at complete rest just to maintain vital functions. TDEE adds calories burned through daily activities and exercise.

Which formula is used?

The Mifflin-St Jeor equation is used as it is considered the most accurate for most adults by nutrition research.

How do I use TDEE for weight loss?

To lose weight, eat 300-500 calories below your TDEE. For weight gain, eat 300-500 above. A 500 cal/day deficit roughly equals 0.45 kg (1 lb) per week.

Does it account for body composition?

The formula uses height, weight, age, and gender. It does not account for body fat percentage. Very muscular individuals may have a higher actual BMR.
