Understanding your TDEE
Your Total Daily Energy Expenditure (TDEE) represents the total number of calories your body uses each day. It accounts for your Basal Metabolic Rate (BMR) — the energy needed for basic bodily functions at rest — plus the additional calories burned through physical activity, exercise, and the thermic effect of food.
How to use your TDEE
- Lose weight: Eat 300-500 calories below your TDEE
- Maintain weight: Eat at your TDEE
- Gain muscle: Eat 200-400 calories above your TDEE while strength training
For the most accurate tracking, pair your TDEE with Healthly's AI-powered food logging. Simply snap a photo of your meal and Healthly will calculate the calories and macros automatically.
