TDEE
Definition: Total Daily Energy Expenditure — the total number of calories your body burns per day including your BMR, physical activity, and the thermic effect of food. Your TDEE determines whether you gain, lose, or maintain weight.
Detailed Explanation
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a 24-hour period. It is composed of your BMR (Basal Metabolic Rate), exercise activity, non-exercise movement (NEAT), and the thermic effect of food digestion.
Practical Application & Guide
Your TDEE is the target you must compare your daily intake against. Eat below your TDEE to lose fat (deficit), eat above it to gain muscle (surplus), or eat at your TDEE to maintain weight.
Common Pitfalls & Mistakes
Using generic online calculators without adjusting for actual daily step count and workout consistency, which often leads to overestimating your actual energy expenditure.
