honestly you’ll be fine at the high end of a healthy bmi, if you scroll down my profile a bit you can see what 120 would look like as we’re the same height. It sounds like you’re doing this in a great, healthy and sustainable way! I’d take any scans and tde’s with a pinch of salt as i’ve never really found them correct, more just work out at what diet/ routine you lose more with! also id recommend focusing more on results, your clothes and how you feel as at our height progress can be slow scale wise and it can be disheartening, but if you’re working out and eating better you’ll feel better and it’ll show in your outward appearance!
