Calorie Deficit Calculator: How Does It Work?
A calorie deficit is commonly discussed in connection with weight loss.
The basic concept is simple: energy intake is compared with estimated energy expenditure.
A calorie deficit generally means consuming less energy than your body uses over time.
Before estimating a deficit, it can be useful to understand your resting energy needs using the BMR Calculator.
BMR represents estimated energy used while your body is at rest.
Your full daily energy expenditure can be higher because of movement and activity.
Term Meaning Calorie intake Energy consumed through food and drinks Energy expenditure Energy used by the body Calorie deficit Intake below estimated expenditure
