Frequently Asked Questions
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including your basal metabolic rate (BMR) and physical activity. It's the foundation for determining your calorie needs.
How many calories should I eat to lose weight?
A safe weight loss rate is 0.5-1 pound per week, which requires a daily deficit of 250-500 calories from your TDEE. Never go below 1,200 calories per day for women or 1,500 for men without medical supervision.
How accurate is this calculator?
This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate BMR formulas. However, individual metabolism varies, so use this as a starting point and adjust based on your results.
Does this calculator account for muscle mass?
This calculator uses standard formulas that estimate BMR based on weight, height, age, and gender. For more precise results that account for body composition, a DEXA scan or professional assessment is recommended.
