Understanding Energy Expenditure

Energy expenditure refers to the amount of calories your body burns in a day. This includes calories burned through basal metabolic rate (BMR), physical activity, and digestion. The EER calculator takes into account your BMR and activity level to determine the number of calories you need to consume to maintain your current weight.

EER formula


  • EER = 662 – (9.53 × A) + PA × [(15.91 × W) + (539.6 × H)]


  • EER = 354 – (6.91 × A) + PA × [(9.36 × W) + (726 × H)]
PA Males Females
Sedentary 1.0 1.0
Low active 1.11 1.12
Active 1.25 1.27
Very active 1.48 1.45

Understanding Your Results

The EER calculator will provide you with a daily calorie needs to maintain your current weight. It is important to understand that this is only a starting point and that your calorie needs may change as your weight or activity level changes. To lose weight, you will need to consume fewer calories than your EER, and to gain weight, you will need to consume more calories.


Determining your energy expenditure is important for achieving and maintaining a healthy weight. The EER calculator is a useful tool for determining your daily calorie needs to maintain your current weight. By understanding energy expenditure, how to use an EER calculator, and interpreting the results, you can set and achieve your health and weight goals.

Remember to regularly re-evaluate your calorie needs as your weight and activity level change. Additionally, you can consult other resources for more information and further reading.
