I think it’s just a part of aging! Just keep playing around with things you can do! Try removing added sugar from your diet, eating out less, or having longer fast periods.
Personally, my weight doesn’t even budge when I’m doing anything less than 22:2. I also seem to have to do either extended fasts or increase my calories suddenly before I decrease again to stop from hitting plateaus.
I started back after a similar break about three weeks ago. It was surprisingly easy at first, but the last few days have been more difficult. I think my cycle is playing a role here — I started during that time of the month, and now I’m about a week away from it beginning again. Curious if others also find fasting harder around this part of the cycle.
