A caloric deficit, also called an energy expenditure, is any thermodynamic deficit or shortage in the amount of calories consumed (or an increase in the amount of calories lost) relative to the amount of calories required for energy homeostasis.
To lose weight, an organism must create a caloric deficit by reducing the amount of calories that it consumes by reducing its food intake or by increasing activity.[1] As the calories required for energy homeostasis decrease as the organisms's mass decreases, if a moderate deficit is maintained eventually a new (lower) weight will be reached and maintained, and the organism will no longer be at caloric deficit. (A permanent severe deficit, on the other hand, which contains too few calories to maintain a healthy weight level, will result in eventually result in starvation.)[2]
