Frequently Asked Questions
TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body burns in a day, including basal metabolism, physical activity, and digestion.
TDEE is calculated by first estimating your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then multiplying by an activity factor based on your exercise level.
Knowing your TDEE helps you plan your calorie intake for weight loss, maintenance, or muscle gain. Eating below TDEE leads to weight loss, above leads to weight gain.
