Understanding Calorie Needs
What are Calories?
Calories are units of energy that our bodies use to perform daily activities and basic physiological functions. The calories you consume through food and beverages provide this energy.
How Calorie Calculation Works
Our calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating calorie needs. It calculates your Basal Metabolic Rate (BMR) – the calories your body needs at rest – and then multiplies it by your activity level to determine your Total Daily Energy Expenditure (TDEE).
Achieving Your Goals
Depending on your goal, we adjust your calorie needs:
- Weight Maintenance: Consume the same number of calories as your TDEE
- Weight Loss: Consume 500 calories less than your TDEE per day (about 0.5kg loss per week)
- Weight Gain: Consume 500 calories more than your TDEE per day (about 0.5kg gain per week)
Frequently Asked Questions
How accurate is this calorie calculator?
While our calculator uses scientifically validated equations, individual results may vary based on genetics, muscle mass, and other factors. Use the results as a starting point and adjust based on your progress.
Why is my calorie need different from other calculators?
Different calculators may use different equations (Harris-Benedict, Katch-McArdle, etc.) or have varying definitions of activity levels, leading to slightly different results.
Should I recalculate my calorie needs over time?
Yes, as you lose or gain weight, your calorie needs will change. We recommend recalculating every 4-6 weeks or after significant weight changes (±5kg).
