How Many Calories Does the Average Person Burn Per Day?

Daily calorie expenditure — sometimes called total daily energy expenditure (TDEE) — is made up of several components that add together to give your overall burn.

Basal Metabolic Rate (BMR)

The largest share, typically 60–75% of total expenditure, is your basal metabolic rate: the energy your body uses simply to keep you alive — breathing, circulating blood, and maintaining organ function. BMR is strongly influenced by lean body mass, so two people of the same weight can have meaningfully different BMRs.

Physical Activity

Movement — both structured exercise and everyday activity like walking, fidgeting, and standing — accounts for the most variable portion of your daily burn. Someone with a desk job who does little structured exercise may burn only a few hundred kcal through activity; someone physically active throughout the day can burn considerably more. For a broader look at how activity feeds into your overall picture, see how the body burns calories through movement.

The Thermic Effect of Food

Digesting and absorbing food itself uses energy — roughly 10% of total intake on a typical mixed diet. Protein has the highest thermic effect of the three macronutrients, which is one reason protein intake is often emphasised during a GLP-1 journey.

How Sex and Body Composition Affect the Number

On average, people assigned female at birth tend to have a lower TDEE than those assigned male at the same weight, largely because of differences in muscle mass and hormonal factors. For a closer look at typical figures, the pages on average daily calorie needs for women and average calorie intake for females explore this in more detail. Estimated figures often cited in health literature suggest average adult women may burn roughly 1,600–2,400 kcal per day and adult men roughly 2,000–3,000 kcal, but these are broad ranges — individual variation is significant. All of this sits within the wider context of understanding your calorie deficit and how it affects your progress.

Knowing roughly how many calories you burn is only half the picture — the other half is understanding what you are actually consuming. That is where GLP Trackr's AI food scanning makes a real difference.

Point your phone camera at a meal and the app estimates calories, protein, and macros in seconds — useful when appetite is low and the last thing you want is to weigh and log every ingredient manually. You can also scan barcodes or search a food database for packaged items, making it easy to see whether your intake is aligned with your energy expenditure, without turning every meal into a chore.

Alongside food logging, GLP Trackr lets you set a daily calorie target and tracks your progress against it throughout the day. If you also log your steps via the daily check-in, the app gives you a fuller picture of the activity side of the equation too.

General educational ranges — like the figures discussed above — are a useful starting point, but the right calorie target for you personally is something to work out with your prescriber or doctor, who can factor in your health history, the dose you are on, and your goals. GLP Trackr helps you record what you are eating so that conversation is informed by real data rather than guesswork.
