Frequently Asked Questions
What formula does the TDEE calculator use?
The Mifflin-St Jeor equation is used to calculate Basal Metabolic Rate (BMR), then multiplied by an activity factor to get Total Daily Energy Expenditure (TDEE).
What activity levels are available?
Sedentary (desk job, no exercise), Lightly Active (1-3 days/week exercise), Moderately Active (3-5 days/week), Very Active (6-7 days/week), and Extra Active (physical job + daily exercise).
How many calories should I eat to lose weight?
A deficit of 500 calories/day from your TDEE leads to approximately 0.5 kg (1 lb) of fat loss per week. The calculator shows this target automatically.
