Your Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn in a day based on factors like age and activity level. Get recommendations based on your results.
TDEE does not directly measure the total amount of calories burned per day, it is an estimate based upon factors, including age and activity level, and it may not accurately reflect the health or wellness of individuals of a specific race/ethnic group, those with high muscle mass, pregnant women, children, the elderly, or those with specific health conditions. TDEE should not be used as a sole diagnostic tool.
The TDEE calculator does not determine eligibility for any weight loss medications or treatments provided via the Hims/Hers platform. Consultation with a healthcare provider is required to assess suitability for any medical treatment based on individual health and medical history.
TDEE may not be accurate for children, pregnant women, or older adults.
Your Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn in a day, based on the following factors:
Basal Metabolic Rate (BMR)
The energy you use while at rest in order to maintain basic bodily functions. Based on your age, gender, height, and weight.
Activity level
This includes deliberate exercise (Exercise Activity Thermogenesis) and other daily activities that burn energy (Non-Exercise Activity Thermogenesis). The more active your lifestyle, the higher your TDEE.
Thermic effect of food
The amount of energy it takes for your body to digest and process food, which varies based on what you’re eating. For example, protein takes more energy to digest than dietary fat.
Here’s a breakdown of TDEE. Please note the exact percentages will vary by person and that your TDEE varies day by day.
TDEE is measured by multiplying your Basal Metabolic Rate (BMR) by your activity level.
Your BMR is calculated using one of the following formulas: Katch-McArdle (the only one that factors in lean body mass), Mifflin-St. Jeor, or Harris-Benedict.
Knowing how many calories you burn a day can help you estimate how much you should be eating in order to maintain, lose, or gain weight.
Keep in mind that weight loss goes beyond calorie restriction. Healthy and sustainable weight loss requires a comprehensive approach that prioritizes exercise, nutrition, hydration, and sleep.
Yes, you can increase your TDEE through lifestyle changes that are part of a comprehensive weight loss plan.
Exercise
Regular physical activity, including small movements throughout your day, can increase your TDEE. Strength training also helps build muscle mass, which contributes to a higher BMR.
Nutrition and mindful eating
Make what you eat count—whole grains, fruits, vegetables, and nuts and seeds are all nutrient-rich. Eating lean proteins can also increase the thermic effect of, as they take more calories to process. It’s also important to understand your Eating Patterns and manage food cravings.
While knowing TDEE can help those who want to gain or lose weight, TDEE does not measure if you’re in a healthy weight range. Body Mass Index (BMI), however, does. For more information, see here.
