I think intermittent fasting is way more sustainable. You are also achieving roughly the same thing, because your body does ketosis anyway as soon as you stop eating for even a short amount of time e.g while sleeping. "keto" diet is just trying to find a way to allow you to continuously eat without breaking it. I only do IF in terms of eating one main meal a day, i've never intentionally done this, i'm just not a morning person, and lunch always felt optional - However I've noticed quite clearly that even a small sugar-laced high-carb snack will destroy this for the day, e.g if I decide to have a croissant one morning as I occasionally do (not because i'm particularly hungry but because it looks damn tasty), then I have to accept that today i'm going to be more hungry and want to eat more - it's these big sugary carbs outside of meal time that keep everyone's hunger up by switching off ketosis. For comparison, having a few nuts is a much better snack, it doesn't make you more hungry because you are able to continue burning fat afterwards.
