OP YANBU.
I've got something to add, and I might be talking shite and misunderstanding the illness but I'll say it anyway to see if anyone agrees.
I've always thought the "treatment" for anorexia is a terrible thing to do to someone in that situation (I'm talking about the admitting to hospital and "making" them eat a certain amount with the threat of tube feeding etc if they dont)
They are just being fed. Which may seem good because it is nutrition and it will make them put weight on when they jump on the scales - but what sort of weight? In my opinion, force-feeding and fattening-up can't cure eating disorders. Food is perceived as a punishment.
There must be a more positive treatment process, one that will encourage the patient to become more independent.
If the weight they are gaining is fat, imagine how terrifying this would be to someone for whom fat is the enemy. If only they could place more emphasis on body composition. They could help the girls achieve a super-lean but HEALTHY body by building up muscle and lean mass. A big part of the programme could actually be exercise in the form of weight training. A carefully selected diet with the correct amount of life building protein and energy giving carbohydrate to fuel their body sculpting programme. They would be constantly reassured that they are not getting fatter, but stronger and leaner, like athletes and ballet dancers. They could have rippling six packs and beautifully defined arms and not an ounce of fat on them (not literally - but could perhaps aim for the lower end of a healthy fat percentage for a woman of perhaps 15- 18% - which is incredibly hard for most of us to achieve, and is a very lean and defined look, periods would return, health and bone mass could be maintained at those levels). They could be empowered by this achievement.
They could weigh them daily using the kind of scales that tell you what is fat and what is muscle, and show them each day what muscle they have built, and reassure them that they have only gained small amounts of fat, showing them the improvement in their body composition in terms of lean vs fat. They could gain confidence as their new, strong, but still very lean bodies emerge. They could keep their need for control but direct that into having a perfect but HEALTHY body with the right education.
Am I talking out of my arse? If so, apologies. And for the OP, I'm not trying to undermine the treatment she is having, I am only talking about force feeding really, I have no idea what else goes on in these units.
