What if "dirt" is harmful, and causes your body to degrade appetite in attempt to overcome the irritants?
I agree we've evolved perhaps, but sometimes modern is better (e.g. portion control). Is it harmful to "feel" hungry and not sate your appetite?
This is something that most people don't understand, given that we live in a world where food is cheap and plentiful.
As many people who have gone through fasting-based diets have discovered, there's a difference between "I'm hungry" and "I need calories, I'm getting weak and tired." Learning that difference is how you discover the actual amount of food your body requires, not just checking off three meals per day.
The feeding patterns of our ancestors were very far from "eat as much as you want all the time with no physical effort required," and that was normal for 15,000+ years, so it'll probably take longer than the 100-200 or so since industrial food production began for our brains and bodies to adjust to the new normal. That, or we'll just have to start teaching our kids about cravings vs hunger vs actual food-need.
What are the qualia of non-hypoglycemic hunger?

I've met others who simply don't experience hunger pangs, but I've always felt them and I didn't know how fully in-my-head it was until I tried intermittent fasting a few years ago.
This is so true and it absolutely blew my mind to discover. Like a scifi plot where the air is "poison", you go outside, and... nothing happens.
It was uncomfortable at first, but it's mostly mental. So much of the "hunger" signal is conditioning that, once you decondition it, it just goes away.
Even when I'm fasted to the point where I'm mentally and physically sluggish, there are still no hunger pangs as severe as the ones I used to have between lunch and dinner when I never went more than 8 hours between meals.
I can't recommend it enough. I don't enjoy any particular clarity boosts or lightness like some purport to have, but I do enjoy spending less money, dealing with fewer errands, and being less fat.
I try to not eat after ~8PM, and to go for as long as I can without eating after waking up. In practice, this is usually ~1130 but sometimes as late as ~230. Then I just eat smaller meals, 50-70% of normal size. In this way, I can eat basically whatever I want, on the same schedule as anyone else.
Most of us are so sedentary but eating like construction workers (at least I was). I also cut my food intake by something like 30-40% with nothing more than a week or two of discomfort.

Excessively fast weight loss can cause liver injury. Most obese people will already have some degree of fatty liver disease (NAFLD), and while gradual weight loss is beneficial in reversing that liver disease, excessively fast weight loss can have the opposite effect and promote liver disease progression.
Not only is it throwing off hormone/endocrine production, the toxins that have been stored in the fat cells are all being filtered through the body at the time of breakdown.
Do people with bodies that are better adjusted to industrial foods reproduce at a faster rate? If not then I don't see any kind of evolutionary pressure that would cause people's bodies to adjust over the generations. My impression is that evolution in humans has stagnated since modern society came about.
