Daily calorie intake (DCI)

An estimate of how many calories you can consume within the next 24 hours to maintain your current weight.

Whereas basal metabolic rate (BMR) is about the number of calories your body needs daily to function effectively when at rest, DCI also includes the number of calories you need to function effectively during your daily activities. Thus, to calculate your daily energy requirements, two aspects are considered:

Basal Metabolism (BMR): the energy your body needs to maintain basic body functions such as breathing, heart rate and temperature regulation, and your Energy for Activity: the energy your body needs to move, depending on your physical activity level.
