Yes, though not eating at all seems to be much more pleasurable when trying to lose weight than just eating ~500kcal and feeling absolutely miserable due to one's body shutting down. Though I would skip water fasting and replace it with vitamin/electrolyte water fasting instead as one has only about a week of B1/B3 reserves and when those are gone, people might get into states resembling multiple sclerosis or schizophrenia, which doesn't sound like fun.
