i went through stages.
1st month: looking or thinking about food and eating made me sick. i was like REPULSED.
month 2-3: didnt want to eat (but no longer REPULSED) though i forced myself to eat because i was getting weak. i had a very strong restriction so wasn't able to eat much anyway.
month 4-7: there would be days that i wanted to eat and days that i didn't. i stopped forcing myself to eat on no-hungry days at this point and just ate when i wanted to because i started to develop this thing where i felt like eating was WORK and i didn't like that. my restriction was still doing its job though, so i still couldn't eat much anyway.
month 7-12: struggled to up my calories to ease into maintenance and i think my not-wanting-to-eat phases during this time period had more to do with a mental block than anything else. i had a bit of a time when i had a challenge "allowing" myself to eat higher calorie foods and carbs, ha. fear of weight gain and all that. though in hindsight i needn't have worried, as my restriction kept me in check.
1 year and onwards: i still get the odd don't-want-to-eat or oops-i-forgot-to-eat days here and there. not as often and regluar as before, but they show up every once in a while. i don't sweat it, as i know there will be hungry days too. my restriction is still very much in play, even at 5 years out, and i have learned over the years what foods and what amounts i can consume before i hit my full mark. i was/am a regular food tracker so its second nature. i tend to only eat things that i really want because, why fill my valuable limited real estate with something meh? luckily the list of things i want does not comprise of just junk. while i do enjoy a bite of dessert and a bowl of chips, i love me a salad just as much. though personally, my fave kind of meal is when there are an abundance of different things to take a bite or two of (like hors d'ourves at a cocktail party, or a tasting menu, or dim sum/tapas/izakaya, or when i go to a restaurant with a large group and get to have a bit of everyone's meal!)
anyway, i think i may have gone on a tangent there, lol.
but yeah, you are not the only one that gets the food aversions, and while you will get differing advice on this topic, i would say go what works for you. if you are getting worsening physical symptoms from not eating, or if your labs are not coming back satisfactorily, of course, please speak to a medical professional. otherwise, if you are losing weight, AND suffer little to no angst, then in my non-medical opinion, you're golden.
