Intermittent fasting makes sense, why have your digestive system constantly processing mindless food. When your body finishes digesting food, it kicks into a different mode in which cellular clean ups can happen, it's not busy sorting out the incoming nutrients so it can do some tidying up. Let yourself feel hunger - it's a primitive necessity, to feel hungry, go hunt, expend energy hunting WHILST hungry, tipping the cells into having a new purpose, keep going with little. Then. Eat.
