The Total Daily Energy Expenditure (TDEE) is a crucial measure of the number of calories your body needs to maintain its current weight based on your activity level. By understanding and calculating your TDEE, you can better manage your diet, fitness routines, and overall health goals. Enter your weight, height, age, and activity level to determine your TDEE.

TDEE Calculation Formula

The following formula is used to calculate the TDEE:

TDEE = BMR * Activity Level Multiplier

Variables:

  • TDEE is the total daily energy expenditure (kcal/day)
  • BMR is the basal metabolic rate (kcal/day)
  • Activity Level Multiplier is the factor that represents your daily physical activity level

To calculate the TDEE, multiply your BMR by the appropriate activity level multiplier.

What is TDEE?

TDEE represents the total number of calories your body needs to perform all of its daily activities. This includes everything from basic metabolic functions to physical exercise. Understanding your TDEE can help you manage your weight, as eating above your TDEE will result in weight gain, while eating below it will result in weight loss.

How to Calculate TDEE?

The following steps outline how to calculate the TDEE using the given formula.

  1. First, calculate your BMR using your weight, height, and age.
  2. Next, determine your activity level multiplier based on your daily physical activity.
  3. Use the formula from above: TDEE = BMR * Activity Level Multiplier.
  4. Finally, calculate the TDEE by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Weight = 70 kg

Height = 175 cm

Age = 25

Activity Level = Moderately Active

FAQ

1. What is BMR?

BMR stands for Basal Metabolic Rate and represents the number of calories your body needs to maintain basic physiological functions like breathing and digestion while at rest.

2. How is TDEE different from BMR?

TDEE includes the calories needed for all activities throughout the day, while BMR only includes the calories needed to maintain basic bodily functions at rest.

3. How often should I use the TDEE calculator?

It’s helpful to use the TDEE calculator whenever there’s a change in your weight, activity level, or if you want to adjust your diet and fitness plan.

4. Can this calculator be used for different activity levels?

Yes, you can select the activity level that best represents your daily routine to calculate the TDEE accordingly.

5. Is the calculator accurate?

The calculator provides an estimate of your TDEE based on the inputs provided. For more personalized and accurate figures, consider consulting a healthcare or fitness professional.
