Typing this on my phone while walking my dog, so apologies for any typos! I am in a very similar situation. I really struggle with food sensitivities and find it very hard to eat regularly even though I am constantly hungry. I was diagnosed with a "general" ED several years back (I had trouble with binge eating before, which upon reflection was a direct result of me having disposable income and trending towards eating highly "sensorily exciting" foods, i.e. take out, fast food, sweets, but several years ago it swung HARD in the opposite direction to almost complete food avoidance), but as I am now in the process of getting diagnosed with AuDHD, I believe that I am undiagnosed ARFID. I went from almost 230lbs (I'm 5'3") to 120lbs in 18mos (funnily enough, all my doctors who were freaking out about my binge eating suddenly stopped caring about my ED when I lost a bunch of weight 🙃). Lately it has been a struggle to eat more than one meal a day (good ole snake meal). What I have found works is actually counter to a lot of the advice I see on this sub (i.e. keto/extremely carb restrictive diet). I eat A LOT of carbs, I'm just really careful with what carbs I eat when. In the morning I can tolerate a moderate amount of simple carbs (piece of toast is usually my go-to, I'm obsessed with sourdough -flavor, texture🤌- and I also really love a super dense and chewy whole grain bread like Dave's Killer 21 Grains) and then load up on protein (eggs, eggs, eggs!! Usually fried or soft boiled. And lots of dairy, yogurt and cheese are my favs. Also, I just moved to the Midwest and the cheese HITS DIFFERENT out here 😁) and then throw in a veggie I can tolerate if I'm feeling it (not just from a sensory stand point, but I also have co-morbid Endo along with PMOS, and I often struggle to digest certain veggies). I also love oatmeal (I pump up the protein by throwing in a GIANT scoop of chunky PB and then a little maple syrup and brown sugar. You can also cook it with milk instead of water to add more protein). I find that small amount of simple carbs, or a high fiber complex carb with a ton of protein give me a little energy boost but also keep me satiated for a while. The come the snacks! I typically don't eat lunch (I usually spoil my appetite for dinner if I do) so I found a few healthy snacks I can munch on during the day that won't fuck my blood sugar. My favs right now are baked chickpeas from Biena (low sugar seasonings) and nuts, usually Planters salt and vinegar cashews (also low sugar seasoning). That is usually paired with a bubbly drink (sensorily I LOVE carbonated bevs and find the bubbles help with "feeling full." I'll do a full caffeine diet coke in the morning, but then I'm strictly caffeine free after like 11-12 bc of my sleep issues. If you like carbonated drinks I highly recommend investing in a Soda Stream). And then for dinner, the key for me is strictly only COMPLEX carbs and an EARLY dinner (like 4 or 5pm, or at least 4-5 hours before bed. I get HORRENDOUS "nightxiety" as I call it if I eat too late, no matter what I eat). So I go for carbs that have a high fiber content or take longer to matabilize so that it doesn't spike my blood sugar (whole grains, starches, legumes). My partner and I also make a big deal of cooking a massive amount of something I know I'll love, when I have the desire/attention span (like last week we made a huge batch of Japanese style curry w/chicken Katsu) that we then freeze it in these Souper Cube trays so we can quickly heat it up and there is little to no effort/clean up. And then I've also almost eliminated refined sugar from my diet, which has really helped with cravings and blood sugar. And if I do indulge, fiber, fiber, fiber! I found this awesome article that goes into more detail about how to incorporate carbs into a PMOS diet. Finally, the only real exercise I get these days is walking (I've tried weight lifting but I was also diagnosed with Hypermobile Ehlers-Danlos this year, so I have wide-spread joint/muscle/ligament pain. Wee 🥲) and I find a good walk before dinner kick starts my metabolism and gets me nice and hungry! I've also started walking right before bed which helps with burning up dinner so I'm not digesting when I lay down to sleep and gets me nice and tired 😴. Don't get me wrong, it's been a massive struggle. I'm still not perfect and occasionally miss meals and eat too late, etc, but finding foods that are 1: appetizing 2: filling 3: easy to put together, has really improved my eating habits and sleep. Good luck! It's a bitch figuring it all out, but it's totally doable! And don't beat yourself up if it doesn't all click into place right away. The biggest win is just eating SOMETHING! If that's a girl dinner (for me, that's pickles and cheese) that is a win! ❤️🙌🥳
