Common Questions
What is TDEE? ↓
TDEE stands for Total Daily Energy Expenditure. It represents the total amount of calories you burn in a 24-hour period, including your basal metabolic rate and physical activity.
How accurate is this calculator? ↓
While no online calculator is 100% perfect as metabolism varies by individual, the Mifflin-St Jeor equation is considered the most accurate estimation for most people.
How often should I recalculate? ↓
We recommend recalculating every 5-10 lbs (2-5 kg) of weight change, as your caloric needs shift as your body mass changes.
