Frequently Asked Questions
What is BMR and TDEE?
BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest. TDEE (Total Daily Energy Expenditure) is your BMR plus calories burned through activity and digestion - this is your maintenance calorie level.
How accurate is this calculator?
This calculator uses the scientifically validated Mifflin-St Jeor equation, which is considered one of the most accurate BMR formulas. However, individual variations in metabolism may affect actual calorie needs.
Should I adjust my calories over time?
Yes! As you lose or gain weight, your calorie needs change. Recalculate your requirements every 4-6 weeks or after significant weight changes (5+ kg or 10+ lbs).
