"You're so thin."
I hear that, or Beloved's quips on me being a tiny wee thing, frequently. Pointing out the enormous bags of fat that depend on my chest (G cup in British sizing), or the fact I'm about as tall as an average man my age, doesn't deflect from the fact that I am shorter and considerably thinner than most of the people I spend time with, thinner than woman-bodied people of my age as well.
Doctors have commented favourably on me having a fairly low body weight and decent overall fitness level. I don't get told to lose weight when I have a completely unrelated condition. Some overweight people are not so fortunate, even if when weight on a chart is not correlated to poor overall health.
I don't work at being thin. I don't try to starve myself and my exercise routine is specifically designed for strength and endurance, adding bulk in the form of muscle. I hear that I'm lucky, or that I won some kind of genetic lottery.
I don't try to starve myself, but sometimes my biochemistry and past patterns do. When I'm depressed (clinical, not having a sad time so much as a flat affect, anhedonia and impaired executive function), I forget to eat until I figure out the grey-out from low blood sugar and the severe pain in my gut are signs my body needs fuel. I've been discouraged from being seen and heard, and what better way than programming myself to insubstantiality?
I eat what tastes like food, which is mostly fruits, vegetables, nuts, and meats. Sweet and higher-fat foods I will sometimes nearly inhale when I've been exercising intensely, but I don't reach for them. I don't like the way my body feels when I eat starches, so I eat little in the way of breads, cakes, cookies, potatoes, and the like. When I drink juice, it's diluted usually at least 3:1 with water because it's cloyingly sweet.
I've been through financially difficult times. My response to not having much money for food is typically to not eat at all or ro eat less, not to reach for filling (usually starchy) foods. I haven't built up a layer of fat, except in the chesticles when hormones had their way with my body.
I don't drink alcohol. I used to. I don't like the sensations and altered consciousness that intoxicants induce. I tried edibles once in the past year and they're not for me either. Booze has a lot of calories.
One of the ways I calm my mind is being physical. Walking, working out, to a lesser extent singing. It's a rare week that sees me average fewer than 10,000 steps a day in addition to daily stairs (9th floor) and exercise (4-6 times a week). The activity burns fuel and raises my base metabolism so I need more fuel to maintain function.
I don't manage my pain well. I'm working on improving here, but even as I type this I have two hips that are searing their ache into my awareness. When I'm in pain, what appetite I do have is greatly diminished.
The size I am is a part of me that I don't put any effort into. It simply is, like the colour of my eyes. Yes, they're really brown. I'm not virtuous because I'm kind of skinny.
People who are fat to any degree are not lazy or bad. I find my programming telling me they are sometimes, which is its own kind of disturbing. If you notice me acting, speaking, or writing in a way that implies fat people are inferior, please thwack a portion of sense into me by whatever means you prefer. Preferably consensual.
Here endeth the sermon.
* nethack the original, v3.6.1 and counting.
* unnethack - kitchen sink of additions, harder than vanilla, very actively developed.
* Slash'em/Slash'em Extended/SlashThem - I play this one a lot, basically 3.4.3 with new roles, races, monsters, artifacts, longer dungeon, shorter Gehennom. Kinda hard. Playing as a Vampire wizard is super fun. Playing as a Doppleganger is OP AF. Dev seems stalled for most of these subvariants.
* dNethack - new and actively changing as we speak, new mechanics for almost everything, WAY harder monsters, new roles that are basically impossible to ascend, Elbereth replaced with a series of Wards and spirit bindings that convey an intrinsic but only if you don't break conduct...easily the most complicated and difficult of the current variants. You can play as an android or a convict or a time traveler from the future who doesn't know why he has all these crazy plasma weapons etc.
* FiqHack - mostly UI and QoL improvements...didn't do much for me.
* GruntHack - intended to be harder; can't say, never tried it.
I think that's the major ones? AceHack and NitroHack got folded into one or more of those...NetHack4 became FiqHack I think...NetHack Fourk might be active.
Still a great (set of) game(s).
https://ascension.run/hterm/ appears to have many of the variants Paul listed.
