Hi Meg, I presume you’re trying to lose fat and not weight per se. I started Keto 7 months ago and lost 30# of fat and then "plateaued " to 150# for 2 months. My scale also shows body fat % and although my total weight stayed the same, my BF% went from 21 to 18, but I was stuck on 18 and wanted to get to 10%. I used the 17/7 IF to get to 18%. To break the BF plateau, I did a 3 day fast and that kick started my fat burning again. I’m now at 15% BF and I think it will continue to fall with a combined 17/7 IF and every other week 3 day fasting regiment.
The simple answer my be, start longer fasts until the fat starts burning again.
