I don't think it's not possible to never know when you're hungry, however it may be hard to tell when you are hungry. To tell if you are genuinely hungry, you can check if you are angry, if your stomach is growling or if you wouldn't mind eating anything. You could also drink some water; if you can feel it in your stomach you need to eat.
Hope it helps, good luck! :)
False. I don't think you can do that I think you would have to go somewhere else to provide evidence. Hope this helps:)
