I've been running on IF for at least a decade. Can only eat twice a day. If i try to have breakfast, I don't feel hungry for the rest of the day and have to skip lunch. People in comments mention plateau effect, but this is kind of the point - my weight is stable for years on easy mode and I only have to correct and tweak it slightly +/- a few pounds from time to time.
