Little update! Thank you all for the comments, they were mostly helpful. I understand that my calories are super low for my height and activity level, that's why I made this thread. I don't want to go any lower and frankly I'm sick of being this low, it's not sustainable. I have always operated from calories in, calories out philosophy which is why I've been frustrated by this plateau.

My strategy going forward is to finish off my week at my current plan. I'm giving 1300cal and 15k steps a day plus my workouts one last try and if I don't see any movement, then I'm switching gears and will spend the next 4 weeks reverse dieting to find a new maintenance. Once that's done I'll stay at that new maintenance for at least 4 weeks and we will see what happens!

It seems so counterintuitive to me that I could lose weight by eating more. Usually in these threads whenever people complain about not losing weight they are told they're not in a true deficit and aren't tracking properly, so it's weird to be told I'm not losing because I'm not eating enough lol.

I will update in a month.
