For point one , yes. We have evidence that your body has a steady state homeostatic “weight” that it will attempt to return you to. Which is why on the whole all fad diets are equivalent and none are reccomended.
“Non metabolic” is sort of a vague statement but top of my head besides “organs” i’d imagine the possible gut flora problems could be huge (or it might be great because presumably you have flora right now encouraging excess fat etc)
