Frequently Asked Questions

What is BMR and how is it calculated? +
BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest to maintain basic functions like breathing and circulation. This calculator uses the Mifflin-St Jeor equation: For men: (10 × weight kg) + (6.25 × height cm) − (5 × age) + 5. For women: same formula but −161 instead of +5.
What does TDEE mean? +
TDEE stands for Total Daily Energy Expenditure. It is your BMR multiplied by an activity factor that accounts for the calories burned through exercise and daily movement. TDEE represents the number of calories you need each day to maintain your current weight.
How many calories should I eat to lose weight? +
A common approach is to eat 500 fewer calories than your TDEE per day, which typically results in approximately 0.45 kg (1 lb) of weight loss per week. This calculator shows this value automatically in the "Weight Loss (−500)" card. Always consult a doctor before making significant dietary changes.
Which activity level should I choose? +
Choose Sedentary if you have a desk job and rarely exercise. Lightly Active suits people who exercise 1-3 times per week. Moderately Active is for those exercising 3-5 days per week. Very Active applies to intense daily training. Extra Active is for athletes or people with physically demanding jobs who train twice daily.
Is this calculator suitable for children or teenagers? +
The Mifflin-St Jeor equation is validated for adults aged 18 and above. For children and teenagers, calorie needs are calculated differently based on growth stages. Parents should consult a pediatrician or registered dietitian for accurate guidance for minors.
