Congratulations! Great progress! People often compare their pace to someone else's quick start without factoring in that everybody's different, and results depend heavily on how much weight there was to lose in the first place.
17 kg gone, roughly 40 still ahead. I do see a difference, but transformational? Not yet. Years ago at 68-70 kg, even 2-3 kg showed on me. Now I'm 108, down from 125. With a lot to lose, a big visible change takes time. Comments so far are nearly zero, just one or two people noticing. Body shape matters too, and on mine I know the big difference starts around 85-90. Stay with it, it'll come
