Why do you care about the water weight? Are you a boxer that needs to cut weight to some magic number before his match? If not, what the scale tells you is really just a number. What matters more is body fat %, how good you feel, being in a good shape.
I believe that you guys are going to far on this, dry fast and eat, your weight will go up, when you finish next fasting your weight will be lower than the previous fasting, that’s the goal… Once you hit your goal add the weight you gain every reefed and dry fast that excess and you’re done… Like you want to be 80kg, every time you refeed you gain 3kg, so your last fasting should be when you hit 77/76kg. It’s a hard journey, don’t make it harder… Remember we got here because all of us have some problem being lack of willpower, depression, eating disorders… Making it harder you make easier for us to fail.
You could.
In fact I refed with keto foods and had a water weight stall anyway, but didn’t have the same stall when I refed with watery fruits, vegetables and protein. I’ve never refed on starchy carbs like rice, potatoes or pasta.
I chalk it up to the amount of food (amount of calories) you eat when refeeding.
Just try it and log your weight. If you gain 3 lbs overnight after a refeed, you can bet it’s not fat but water.
