You will put some weight back on, because of water and food in your stomach and intestines. From 183 down to 160, I’d expect you to put that back on, in all honesty. Why are you dry fasting? How long is your dry fast going?
Rolling fasts of 48s and 72s until optimal weight, should include water fasts with apple cider vinegar and baking soda (but not together within 2 hours of each other) to break down/prevent kidney stones.
