BMR adaptation, likely only burning 750-900 cal???

So, studies show that prolonged calorie restriction can cause metabolism to adapt by -10% to -25%, and that would leave me at like 750-900 cal, which I guess would make sense considering the rate I lose at.

I'm freaking out because I'm trying to get to a more 'normal' diet while staying about the same size, but like ... that's crazt

BMR that low sounds surreal to me to be honest, but I don't know the realia of being that low of a weight, so perhaps I'm just blissfully ignorant. What TDEE would that put you at?

Probably 1000 max

I'm so fucking mad. I don't even know if I can fix it by trying to maintain. I have a goal of being at a more normal diet within my maintenance by the next time I go home and making little steps towards that.

New year, new me and all that jazz, but right now I'm really focusing on getting off lax for good

Can you give me an "explain like I'm five" brief on this? I read through it and honestly was lost. (Which is so frustrating, because I used to be so intelligent and would even watch medical lectures for fun/my own learning interest!). I read the entire article and re-read the abstract, but just don't get the overall concept/thesis.

Is it saying that calorie restriction (without exercise) does lower your TDEE, but it's okay because it affects your leptin, thyroid, etc., in beneficial ways? Or did I totally miss the point?

But it's simple math at the end of the day anyway; if you weigh less you'll have a lower TDEE, because TDEE includes weight in its calculation

The thing is at very low weights, the body shuts down multiple processes in order to save the calories it needs to exist so say hormone regulation, digestion etc. Unfortunately the only way to fix it or improve it is increasing intake as I'm currently going through something similar to a lesser level as I weigh much more, but the only actual solution is increasing intake and/or weight. I haven't attempted yet so can't give advice on how much you need to increase by and for how long etc. Then obviously there is the serious risk of refeeding so I'd never dream of telling you to just eat more (even if it was just that simple sigh) as you'd likely need monitoring by a doctor. I'm unsure how greatly the numbers reduce, but I'm currently maintaining on 200-300 less than my estimated TDEE roughly if that helps. I'm sorry I cannot be more useful or helpful, I just hope I can help make you feel a little less alone 💓

Horomone regulation is being "outsourced" anyway, so to speak, as I'm on HRT. I'd be okay with increasing intake, but I've gained 3 pounds eating less than 500 calories a day over the past week.


Ideally I could maintain at 68-70. I was at 72, stopped lax, upped sodium, and ballooned up to 75

Does anyone else have issues with this level of metabolism fuckery??

Just remember that adaptation works both ways. Your metabolism will slow down when you are restricting, but increasing your intake will increase your metabolism (even though there will be a really uncomfortable transition phase).

I’ve been through the weight restoration process twice in my ED history, and it’s really difficult when you’re seeing the weight gain come faster than expected. But it does hit a plateau!

I am not going to gain weight. The thought of weight restoration i would rather stab myself. I refuse to go over bmi 11s.

i was wondering if i could work towards a more maintainable maintenance. I have an acquaintance on edtwt who's the same height and weight and maintained on 1800, though I think she did more walking than I, but not by a ton, the difference between 10-15k and 20k steps.
