And it's not just the texture pickiness that gets us in trouble, but I think I have some food sensitivities too (and we know how common those are for us spectrumites). Then there's the mentality as a kid, if your family is on a poor budget (I was one of 4 kids in my family and we didn't grow up having a lot of money), then you eat more poor quality food, if eating makes you feel like sh*t, you're not going to want to eat. Like, there are a lot of things that seem to set me off. If I eat too many refined enriched grains, my abdomen makes slurping sounds for hours and I get horrid ass-ripping constipation. I have unfond memories as a child, of my mom feeding me laxatives, stuffing suppositories up my ass, having me drink grape juice, prune juice even drinking it while sitting on the toilet, guzzling metamucil, using enemas, you name it, I tried it. Even funnier, fortified insoluble fiber makes me s**t myself. This is why you won't find me eating wheaties or any other breakfast cereal that advertises fiber fortification on the label. I also can't do hamburger helper (which was fed to me many times a week growing up because it's so cheap). It also gives me diarrhea, as well as some foods that are heavy on the msg. I generally avoid hfcs. It makes me cramp and fart badly. With that said, I distance myself from enriched, fortified cheap mutant white bread. I have a preference for "health nut" by orrowheat, it doesn't bother me. Now, when it comes to milk, low fat dairy does some times make my stomach hurt, so I don't go low-fat, I drink whole milk and I'm fine with it as long as I'm not having tons and tons of it. And dyes (like red 40) make me fly up to the ceiling and lose my attention span. and I don't know what they put in cake frosting either, but I usually knock it off, as it makes my lips and tongue tingle and go numb like the start of an allergic reaction (I'm also allergic to sour patch kids candy something fierce for whatever that means, prepackaged toaster strudel also made my mouth swell so I got rid of it as well).
Over time, me not wanting to eat as a kid (from food making me feel bad), perfectionistic tendencies (to attempt to measure up to being good enough by my parents NT standards prior to my diagnosis), stimulant adhd medicine I was put on from age 10 to 21 (from being diagnosed as adhd at age 10), having 3 overachieving competitive sisters egging you on, trying to find a way to cope for being severely bullied at school (when you're starved numb past a certain point, you can't be bothered to give two f*cks, and especially about the emotional baggage your parents can't handle dealing with so you just stuff it under your hunger). And what do you get? a recipe for anorexia. bf had an intervention with me and I got help when I was 20. Did it start out like anorexia nervosa? No. But it certainly ended up that way.
Today I am a healthy woman, weighing in afaik the last few times I've been told around 105 lbs. Which makes sense in the context of my small frame and my height of 5'2". It's just the weight my body likes to "stick" at, as I've been the same size for a number of years. And digestively, I certainly feel so much better now too.
As for other aspies, the two I am friends with currently, one seems to have a metabolic type of disorder of some kind. He is overweight, diabetic too and he's trying to figure out what is wrong with him (eating makes him feel awful many times, he has lots of health issues, even the littlest of things spike his blood sugar more than it ever should). The other is very thin, with what seems to be low muscle tone, and he actually can't eat some things because he's actually had to have part of his bowel removed. Safe to say that neither of them are really typical in that regard.
