The idea of “maintenance” calories is pretty simple. It is the amount of energy (calories) a person can take it without gaining or losing body weight. 

There are many calculators and estimations for this number in normal circumstances, and even the NHS recommendation of 2000 calories for women and 2500 calories for men tends to be pretty close.

When we are trying to gain weight or muscle mass, we eat more than our maintenance. When we are trying to lose weight, we eat less. And as our body size changes, so does our maintenance intake.
