Our calculator uses the Mifflin-St Jeor equation, which is considered the most accurate method for calculating calorie needs. However, individual results may vary based on metabolism and other factors.

This is a formula that calculates your Basal Metabolic Rate (BMR) - the calories your body needs at rest. We then multiply this by your activity level to get your total daily energy expenditure.

You should recalculate whenever your weight changes significantly (5kg or more), your activity level changes, or every 3-6 months as your metabolism adjusts.

Yes! Select "Lose weight" as your goal, and the calculator will provide a calorie target that creates a deficit for healthy weight loss (about 0.5kg per week).
