Calorie Calculator (TDEE) — frequently asked questions
What's the difference between BMR and TDEE?
BMR is the calories you'd burn at complete rest. TDEE multiplies BMR by an activity factor to estimate what you actually burn in a day.
How many calories to lose weight?
A deficit of about 500 kcal/day below maintenance typically loses around 0.5kg (1lb) per week. Don't go too low — consult a professional.
Is the Mifflin-St Jeor equation accurate?
It's one of the most accurate predictive equations for resting energy, but it's still an estimate; real needs vary by individual.
Is it free?
Yes, free with no account.
