How Many Calories Do You Burn Every Day?

Your body is always burning calories. Up to 75% of your daily calorie burn is just for basic body functions like breathing, circulating blood and building cells. This means that even if you are just sitting around all day, you'll still burn at least 1,300 calories—and likely more. As you move your body through daily activities and exercise, you can add hundreds more calories to your total energy expenditure.

If you are curious how many calories you are burning in a day, you can calculate your energy balance to get a general estimate. Once you know your number, you can get a general estimate of how much to eat and exercise each day to maintain your weight. If your goal is to lose weight, you may need to reach a reach a negative energy balance; and if your goal is to gain weight you will need a surplus. To do that, though, you need to know how many calories you burn.

Daily Calorie Burn

When researchers evaluate the total number of calories you burn, they refer to the number as your total energy expenditure (TEE) or total daily energy expenditure (TDEE).

TEE (or TDEE) is a combination of these different factors: These include resting metabolic rate (RMR), non-exercise activity thermogenesis (NEAT), thermic effect of food (TEF), and calories burned during exercise.

Here is a closer look at each of the factors used to measure your daily calorie burn.

• Resting Metabolic Rate (RMR): Your RMR is the amount of energy your body needs to maintain basic functions like breathing, circulating blood and building cells. Things like age, body size and gender affect your resting metabolic rate. Your RMR accounts for 60% to 75% of the total number of calories you burn each day.
• Non-Exercise Activity Thermogenesis (NEAT): This is the amount of energy that your body uses to do daily activities like washing dishes, typing on your computer, or walking around your office. The number of calories you burn from NEAT varies greatly based on your activity level.
• Thermic Effect of Food (TEF): Your body burns calories to chew, digest, and store food. Each type of food (macronutrient) has a different TEF. Eating protein burns the most calories by a small margin. TEF accounts for about 10% of the total number of calories you burn each day.
• Calories Burned During Exercise: The actual number of calories you burn during your workouts will depend on the intensity and duration of each session. Calories burned through exercise and non-exercise physical activity account for roughly 15% to 30% of your TEE.
  

How to Track Total Energy Expenditure

There are three common methods to estimate the number of calories burned each day. There are pros and cons to using each method. You can use more than one method and compare results to get the best estimate.

Metabolic Testing

The equipment required to perform metabolic testing is fairly expensive and used to be available only in hospital or lab settings. However, many health clubs now offer metabolic testing at affordable prices.

For some people, the test results help them schedule workouts and diet plans more effectively. But some critics feel the tests are not very accurate and therefore not worth the cost.

When you get re-tested to measure progress, it is usually smart to have the same technician re-do the tests and to use the same equipment. And since your body weight can vary by several pounds from morning to evening, it's also best to do your re-test at the same of day as the previous test(s).

Activity Monitors

Devices by brands like Polar, Garmin, and FitBit and are widely available online and in sporting goods stores. The gadgets monitor your daily movements to determine an estimated number of calories burned each day. 

Some independent tests have shown that the devices are not completely accurate at providing an accurate number of calories burned. But the devices are easy to use and can provide a very general estimate of variations in your day to day calorie expenditure.​ 

Online Calculators

Calculators and calorie-counting apps can estimate your daily energy expenditure. Of course, the number is simply a guideline, but it's a good place to start if you want to maintain your weight. If you want to gain or lose weight, use a weight loss calorie goal calculator to calculate your daily caloric needs by adjusting your daily calorie count goal down (or up).

Strategies for Weight Loss

It's important to make shifts gradually if your goal is weight loss. For example, if you cut calories drastically to lose weight quickly, your body can fight back by increasing hunger and sparing energy to encourage you to put the weight back on over time. A more sustainable approach may be to focus on the quality of your diet and your activity levels along with slight reductions in calories and increases in activity levels in order to consume less than you burn each day. 

Of course, there are some components of your TEE that are hard to change. 

Increasing your resting metabolic rate, for example, is fairly difficult. And increasing the number of calories you burn when you eat food isn't an effective way to reach your negative energy balance, either. But you can change your daily physical habits.

Between workouts, stay active. If you are able, take the stairs instead of the elevator, walk to the store instead of taking the car and stay active at home to burn calories. You'll boost your calorie-burning potential and you may be able to increase lean muscle mass on your body, which can boost your resting metabolic rate. 

A Word From Verywell

Remember that all calorie counts are estimates. Even the calorie counts on food packages are estimates. So, if you're trying to lose weight, expect that you will need to take some time for trial and error before you find the numbers that are right for you.

Use several different methods to find out how many calories you burn each day. Then experiment with food intake to find the right balance to meet your goals.
