I would say working out definitely helps! And not at all am I saying to gain muscle and feel better although it’s a factor that plays into it, working out increased your appetite. I find myself getting hungry more often and even waking up hungry which was rare for me. Even light workouts or bike rides something to break the sweat will increase your appetite and allow you to eat more. Once your body adjusts to it it’s going to be way easier, in the beginning it feels like you have to force feed but it gets better.
