Frequently Asked Questions
What is TDEE?
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including your basal metabolic rate and all physical activity.
What formula does this use?
It uses the Mifflin-St Jeor equation, which is the most accurate formula for estimating BMR (Basal Metabolic Rate) currently available.
How many calories should I eat to lose weight?
A deficit of 500 calories per day below your TDEE typically results in about 0.5 kg (1 lb) of weight loss per week. The calculator shows this as the Weight Loss target.
