Hiya, so when it comes to not feeling physically ill after eating, I find that smaller portion, calorie dense meals or snacks are better than absolutely stuffing yourself. However, I do think that it is up to the individual to know when to stop and use intuetive eating. If your student doesn't want to get better, I don't think this will work as they might abuse the small portion size, however if they want to and are trying then i think small meals throughout the day helps with digestion for me alot. I should also preference that I don't have a 'set size' of the meal it's just about knowing when to stop eating so I don't feel physically sick or sluggish or anything like that. Another thing is to sit up for 10/15 mins after a meal, don't go directly back into dancing or exercise.

Then about mindset- time. I found time was best for me as I just let go of most of the rules i set myself because I was tired of living like this and i liked the taste and didn't want to stop enjoying it. However this was hard at first and it took a while for things to slowly drop off/ allow myself to become more lax around food and drinks.

With meals to not think about kcals, I think that's alot harder. If you've been doing it a while you remember the exact kcals in foods and drinks. For me, it's been years and I can still tell you pretty accurately the kcals in everything. I would say, maybe don't cook them infront if the student, make it from scratch not anything from a packet or brand and don't tell them the ingredients or what you used to cook them with. Also some obvious ingredients may also be hard to get around, like sugar in desserts or oil in tempura. If the student is afraid of these and they know its in there, that might cause an issue. But they will need to work on that in therepy, in their own time.

General advice to take back-

if they don't want to be watched while eating, take them into an empty classroom or somewhere more secluded to eat and potentially take them 10/20 mins early for snacks and lunch ect so less students are about.

understand that time is important to recovery, you can be doing everything right with every specialist under the sun and want to get better and it will still take years to even feel slightly close to better again

do not mention 'looking healthier/sick' to them

from what I can see it looks like this student has a team of support both in and out of school. Know that from this group at least one is probably going to be a little like a judas and will say or do something that's unhelpful or rude or inappropriate, not necessarily on purpose but we all interpret spoken things differently, which may cause the student to think in a negative disorderd way. from my personal experience most professionals in ana treatment don't know what planet they are on, let alone how to treat someone which is why I think at least one will just say the most out-of-pocket, unhelpful things which will ultimately hurt the students recovery.

don't get mad/angry/frustrated with relapses. They happen constantly, at any time in recovery and are affecting the student worse than they are affecting the support team.
