first picture was me before I started my six-month supervised diet (2014). I think I was at my highest weight ever. Second picture (from 2017) is of me when I was two years out of surgery (this was before I had my skin removal surgery, though...I had that in Aug 2018 and March 2019). Last one was of me on my 60th birthday (last year). I've put on some weight since the 2017 picture - but excess skin is gone!
I'm a guy but hope this helps. This came up as one of those "memories" timeline photos - MAY 2019 vs MAY 2020 on the same day. Surgery is a helpful tool, but you have to put in work as well! (VSG not bypass - but same concept)
