The reason is that it works well enough, most of the time, for most people. If you are trying to lose weight, you do not need an exact formula to compute the derivative of your weight with respect to time; you need a mental model of your diet and metabolism that moves you toward your goal. CICO basically tells you to look at your two most important levers for doing that (how much you eat and how much you move) and adjust them until your weight moves in the right direction.

It’s not the calories you burn during the period of exercise, rather it’s the changes to your body that exercise causes that encourage weight loss.
