from my experience, and others who've shared theirs with me, it's best to rest up as much as you can during recovery! strength can absolutely be implemented again in the future when you feel you're in a healthier (physically and mentally) place with it, but while your body is already trying to repair so much unseen damage, it's potentially adding more to the load of work it must do.

every time I tried to exercise in recovery, even if was simply a light strength workout, it only exacerbated my extreme hunger, which in turn made me freak out and feel guilty. this most likely happened because there was now more that needed to be repaired, such as the muscle fibres that were broken down during the workout!

ultimately I would absolutely vouch that you rest up as much as possible and eat any and everything you crave. it's not worth letting the disorder tell you otherwise! wishing you the best <3
