What Is TDEE? Total Daily Energy Expenditure Explained

TDEE means total daily energy expenditure, a rough estimate of how many calories you burn per day (body functions + activity + digestion). It’s a planning number, not a lab measurement. Track intake against a sensible target, then adjust using real trends.

TDEE vs BMR

• BMR / BMR-like resting burn, calories to keep you alive at rest
• TDEE, resting burn plus movement and daily life

Online calculators multiply resting estimates by activity factors. They’re guesses. Useful guesses, still guesses. Background reading often cited in consumer health media includes BMR explainers (e.g. Healthline-style BMR articles) and calorie-counting explainers from Harvard Health.

How people use TDEE

• Fat loss, eat below TDEE on average (deficits shouldn’t be extreme without guidance)
• Maintenance, eat near TDEE
• Gain, eat above

Medical conditions, medications, and history of disordered eating change the advice, ask a clinician.

Where tracking apps fit

Apps don’t know your true TDEE. They help you log consistently so you can see whether your intake lines up with your weight trend. CalBuddy adds photo macro logging, micronutrient gap glances, and buddy alerts so the experiment lasts longer than a week.

Set a target, snap meals, invite a buddy who notices when you ghost the log for two days.

Not medical advice. Calorie targets aren’t appropriate for everyone.
