This is something I've struggled with as well.... I do have a really fast metabolism, but that's only meant that I almost feel the need to eat more and more and more because I know I'll be hungry soon if I don't. As I've gotten older and the metabolism has slowed, I've got a lifetime of crazy bad food habits. I've often joked that the majority of my salary has gone to my stomach, but I think it's probably pretty accurate.
Obviously our relationship with food needs to change... it's crazy that we are so obsessed with it, and think about it constantly. It's stupid that all our social things revolve around meals... there's a trillion other activities we can do with friends and family, but it's always meal-based.
I know you'll probably dismiss this idea straight up, but maybe try a fast.. just go 24 hours without eating. It's not until you've done one that you realise we don't need to eat nearly as much as we actually do. We'd all be fine on a 3rd of what we eat... honestly. If you can try it once, you'll see that not eating, or being hungry isn't that bad. We don't need to be full constantly... I understand where that came from, but we don't need that anymore.
Good luck with the sweats and the filling your house with only health.
