Frequently Asked Questions
What is TDEE?
Total Daily Energy Expenditure is the total calories you burn in a day — BMR multiplied by an activity factor (1.2 sedentary to 1.9 very active).
How accurate is Mifflin-St Jeor?
It is the most accurate BMR formula for the general population in published research. Real-world TDEE can still vary 5-10% by genetics and activity precision.
How do the cut/maintain/bulk numbers work?
Maintain holds weight. Cut = TDEE - 500 kcal for ~1 lb/week fat loss. Bulk = TDEE + 300 kcal for lean muscle gain. Adjust based on 2-4 week trends.
