Do you know how many calories you burn every day? You should if you are trying to lose weight. You can calculate your energy balance and figure out how to much to eat each day when you know your number. You need to reach a negative energy balance to lose weight.
To reach a negative energy balance, you need to make sure that you put less energy in your body than your body uses.
That means that you need to consume fewer calories than you burn each day. 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:
- 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.
- 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.
- 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.
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.
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.
If you choose metabolic testing in a health club, make sure your trainer or technician is qualified to perform the test.
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).
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.
Calculators like the one above 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).
Daily Calorie Expenditure
To reach your negative energy balance and lose weight successfully, try to increase the amount of energy you use 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. 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.
