> I have only ever eaten food when I’m actually hungry

That's very good for you, be glad your genetics / environment enable you to not be hungry, as stupid as it sounds. I'm always hungry, I can always just eat until my belly hurts (with regrets after). I'm under control, do a lot of high intensity cardio and muscle training to increase my total metabolism and practice strong discipline to not overeat. I'm thin with some nice muscles now, but as soon as I let myself go and let "nature" take over, I'll gain weight again because I'm hungry and always was. I'm not complaining, my genetics / environment enabled me to do other things most other people can't do. Life is not fair and the universe owes us nothing.
