CICO is necessary but not sufficient. You also need some strategy for how to achieve CO > CI. Different strategies have vastly different implications in regards to willpower, health outcomes, suffering, time, cost, etc.

CICO is the equivalent of engine tuning, to produce more power you just need to burn more fuel in the same amount of time, easy as a concept but not so easy to achieve sometimes.
