Frequently Asked Questions
Common questions about calorie calculation and weight management.
BMR stands for Basal Metabolic Rate. It represents the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at rest. Knowing your BMR is the starting point for calculating your total daily energy needs.
TDEE stands for Total Daily Energy Expenditure. It is the total number of calories you burn in a day, including your BMR and calories burned through physical activity. It is calculated by multiplying your BMR by an activity factor based on your lifestyle.
We recommend the Mifflin-St Jeor formula as it is considered the most accurate for modern populations. However, the Harris-Benedict equation is also widely used and can be a good alternative if you prefer.
To lose weight safely, a deficit of 500 calories per day is generally recommended. This typically leads to a weight loss of about 0.5 kg (1.1 lbs) per week. Our calculator automatically adjusts for this when you select 'Lose Weight' as your goal.
While our calculator uses scientifically validated formulas, individual metabolism varies. These numbers are estimates to give you a solid starting point. Monitor your progress and adjust your intake as needed.
