This is a curiosity question.

If a person did everything perfectly (the right amount of calories, protein, fat, carbs, water, exercise) and was eating below their CCL, would their body be in a continual state of ketosis? Or does it cycle on and off, giving things a rest in between?

This question is related to the cycle of weight loss. We lose for a while, then the body rests to catch up. Does the same thing happen with ketosis even if a person does everything perfectly?
