I’m currently down over 125 lbs and am weighing at 220lbs and am in maintenance mod

Hello all, in 2017 I had a work-related injury that resulted in me injuring my lower back that resulted in a lumbar laminectomy fusion from my L3,4,5,s1 that failed. I was 358 lbs and started keto to help fight chronic pains and to my surprise it did. I’m currently down over 125 lbs and am weighing at 220lbs and am in maintenance mode. Did all this with a broken back and only physio for exercise.
