The problem with too-hungry people is that yes, they eat too much, and no, they cannot just stop. The way it works is so: they eat a meal, start feeling very hungry an hour later, make an effort and resist eating for another hour, then some more until they can't anymore and they give in and gobble up everything in the fridge. In cases like this skipping dinner is not actually possible, at least long-term.
I would consider adding salt to something to be making that thing less healthy. If adding salt is essential to making something edible, I think it would be healthier to opt for something that doesn't require added salt. That's speaking generally though, someone might not be getting enough sodium, but typically there is adequate sodium in a diet of whole foods.
I'd say it's too strong a claim that adding salt makes things less healthy. Remember that humans, eating generally mostly plants but some meat as well, developed rather strong craving for sodium salt, just like most herbivorous mammals. If you eat enough meat (not boiled) you don't need more sodium, if you eat a little meat or a lot but boiled, it's probably better to add some. If you eat only potatoes, you'll die without added salt (just kidding, who eats only potatoes).
If this is the main reason why we should avoid ultra-processed food, then of course we'll have to avoid seed oils at any cost, as those are both ultra-processed and rather new, certainly not what we were evolved to breathe in at sea level.
There seems to be one particular situation that gets on my nerves and fits into this category. It goes something like these two ways: 1) at the end of an event, everyone is asked unexpectedly to make a short speech about the success of the event, or 2) in the middle of the event, everyone is abruptly expected to produce some creative output. Number two is, of course, worse, and can make the whole event a complete hell for half the participants. Number one is just annoying. Perhaps it would be better to ask if anyone has anything to add at the end, so that we can hear from the few people who really have something to add? Usually, however, this is resolved by practically everyone saying meaningless trivia in a couple of sentences. Even though many people can feel okay with their own triviality, others feel embarrassed that they had nothing meaningful or witty to say and that they therefore wasted people's time.
But then why do medicine portals advise us to be wary of risks associated with too low sodium? It's claimed to cause insulin resistance, a higher risk of heart disease, hyponatremia, and whatnot. People with any-cause hyponatremia can cure their symptoms with more salt. These people here[1] claim that it's probably not good for healthy people to artificially (i.e. against their natural desire) restrict their sodium. After reading these claims, what's the main good side of reducing sodium intake to pretty low?
