When I'm on vacation my stress is reduced to the point where my 'appetite' drops, and this is despite the fact that I'm increasing my exercise load enormously (surfing, hiking, etc...)

I've noticed that stress causes me mild stomach pain, which can register as hunger. It also causes dry mouth which registers as thirst. If you're satisfying that thirst with sugary drinks long term, then you're going to be in trouble.

There is also so much novelty and more interesting stuff going on while on vacation that I don't find myself poking through the fridge out of boredom.

I also lose so much weight on vacation it's weird. I once lost weight when visiting Japan for two weeks but I swore I was going crazy with the food, so I was confused. But I still managed to eat less than at home (I must have). Definitely a busyness thing.

Im the opposite when it comes to stress. I lose my appetite when I'm stressed but get super super hungry when bored. The lockdowns really messed up my eating habits but thankfully I've shed all the weight now that I can actually do stuff again.
