You can get into ketosis on any kind of diet or eating schedule, it mostly relies on avoiding dietary carbohydrates. If you're curious you can get ketone urine sticks, ketone breath tests and even a non-FDA-approved continuous ketone monitor (SiBio). IF can help because it gives you a long period without carbs so you're naturally getting less of them in a given period, unless you then load up on like white bread. It's mostly a function of what you eat when you do eat.
