Quite a few people do keto long term for overall health or maintenance after weight loss (or without weight loss in the first place). I have never used it for weight loss but those who do often talk about the rebound in weight you mention with short term diets. This is sometimes one reason they end up making this more a lifestyle change than a short term diet for them. As you get adapted keto becomes very manageable, and the higher intake of fat can make it easier to consistently consume fewer calories than they used to eating carbs.
