Frequently Asked Questions

How are daily calories calculated?+
This calculator uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR), then multiplies it by an activity factor to get your Total Daily Energy Expenditure (TDEE). The Mifflin-St Jeor equation is considered the most accurate equation for most people.
How many calories should I eat to lose weight?+
Reducing your daily intake by 500 calories leads to roughly 1 pound of weight loss per week. A 250-calorie reduction is about 0.5 pounds per week. Don't go below 1,200 calories for women or 1,500 calories for men without medical supervision.
What is the difference between BMR and TDEE?+
BMR (Basal Metabolic Rate) is the calories your body burns at complete rest - just to stay alive. TDEE (Total Daily Energy Expenditure) is BMR plus the calories burned through activity. TDEE is what you actually need to eat to maintain your weight.
Is the calorie calculator accurate?+
Calorie calculators provide estimates, not exact numbers. Individual metabolic differences range from +/- 10-15%. Use the result as a starting point, track your weight for 2-3 weeks, then adjust up or down based on actual results.
