Calorie & TDEE Calculator
The calorie calculator uses the Mifflin-St Jeor equation, one of the most scientifically accurate formulas, to estimate your basal metabolic rate (BMR) and total daily energy expenditure (TDEE). Adjust for your activity level to get precise calorie recommendations.
Frequently Asked Questions
What is BMR (Basal Metabolic Rate)?
BMR is the number of calories your body burns at rest, without any activity. It's the minimum energy needed to maintain vital functions like breathing, circulation, and body temperature. The Mifflin-St Jeor equation is one of the most scientifically accurate.
What does TDEE mean?
TDEE (Total Daily Energy Expenditure) is your total daily calorie expenditure considering your activity level. It's the key number for planning your nutrition: to lose weight, consume fewer calories than your TDEE; to gain, consume more.
How many calories should I subtract or add to lose or gain weight?
Generally, a deficit or surplus of 500 calories per day results in losing or gaining approximately 0.5 kg per week, which is a healthy and sustainable rate. This calculator suggests these standard values, but consult a nutritionist for a personalized plan.
