The only kind of diets I know of that people stay on long-term are less strict diets. The stricter the diet, the lower long-term adherence is, which seems logical. Keto is very strict, very measurable. My pediatrician brother goes off and on keto very successfully. Whenever they need doctors for a test of the keto diet, he goes back on it. Despite being low body fat, he tends to lose more body fat than others on the diet, because he's a home chef and marathoner and very much in control of his diet. I tend to not make enough effort to balance my diet on keto, which causes issues that take me off of it, for example, I don't respond well to having too much cheese.
