At your 130lb weight, I’d guess it would be 5-8lbs.
When I went on keto I dropped around 13lbs in the first week or so; it was all water/glycogen. When I went off it I regained that exact same amount in water/glycogen. Pretty normal to lose/gain somewhere around 5% of bodyweight when entering/exiting ketosis respectively.
Even while I was strict keto, fasting added another variable. I typically would lose an additional 1lb per consecutive day fasting, which I would regain immediately upon keto refeed.
Weight doesn’t mean much when your going in and out of keto and fasting. A tape measure is a lot more useful under those conditions!
