I think you can try a few changes, just a few examples that worked for me:
Calorie cycling - increased my daily intake of protein for a week or so
Fast Cycling - Went from 20:4 to 23:1 for about 10 days and it helped
Long Fasts - I have tried this a couple of times only and for me, it didn’t really work. But I know of friends who beat the plateau this way.
I hit a plateau after losing 12KGs in 6 weeks. I took a break from IF for 3 - 4 days but ate at maintenance and after that (now) the scale seems to be moving down again.
I did 1 36 hour a week and that immediately helped and that’s been going strong for a month now. I actually take a whole day off and eat more after that 36 hour too. I’m back to loosing a lb a week again.
