> Like others said, skipping breakfast should not be that big of a deal for a reasonably healthy adult, we didn't evolve having 3 meals a day. Intermittent fasting is a thing too.

I haven’t played the simulator but I wonder if it’s also trying to account for more than just the physiological effects. A friend of mine has autism, and we were getting together one day. On the way over I suggested getting some food since it was close to dinner time. They agreed, gave me some items and I bought us some food. When I arrived they were amped up and excited to show me something. I set the food down, and I ate while they were showing me this thing that had them all excited. They ate some of the food too, but were clearly distracted and not all that hungry. No big deal. But a few hours later I noticed they’d gone real quiet and seemed down or anxious about something. Turned out they had been worrying for the last hour that they had offended me because they didn’t eat all the food and they knew they weren’t going to eat all the food because they were going through a phase where eating in general was just a difficult thing to want to do and so were eating just the minimums they needed to not have other problems.

The entire later half of their evening and their excitement over their new thing had been badly deflated all because of a decision / need to not eat all the food on offer. Never mind that this was nothing new for them. Never mind that I could easily see myself skipping food just for the excitement they were experiencing before factoring in any sensory phases. Never mind that it would be a truly shit thing for me to be offended because they only ate some of the greasy fast food I picked up for us. No this simple and normal act caused them an hour of stress and anxiety over worrying if they’d crossed some social line for doing something I didn’t even notice until they said something.

But it doesn’t matter whether I noticed. Their brain latched onto the “you did something abnormal, people might have noticed, now you need to analyze everything that’s happened to figure out what you next move should be” train of thought and it would not let go. So at least from what I’ve seen, choosing to eat or not can have impacts beyond just “hungry”
