I've been fasting weekly for a long time (after starting with intermittent fasting). I'm glad to see an article like this because I've been waiting to try fasting every other day. My subjective observation is that there is a misconception of what the body does with nutrients and that is why in general people won't think of even trying to fast ever. To use contrasting analogies, it seems in general the perception is that the body works like a car and you have to re-fuel it every few hours in order to keep going. However, from my experience I think the body is more like a factory that creates its own energy. It needs materials, from which a part is used for energy, but thanks to having storage, you have plenty of supplies to keep going until the next shipment of resources arrive. In other words, fuel is burned in proportion to the user of the car, but factories don't necessarily use their materials as soon as it receives the shipment. Factories can store resources and their use is scheduled for a later use. Therefore it is better to optimize for quality of materials, rather than frequency of consumption! Your body will use the materials it gathered from the past few days of consuming food (no citation here, but again just my experience), and the only problem of not eating is the BRAIN's expectation of eating food every day and that feeling of satiation, which is basically a hit of dopamine and not a true sign of wether you need materials and/or energy to survive.
