In my experience, you kind of need to super hydrate before a dry fast to shed lots of water.
Our bodies have ways of holding onto water, and really hydrating, especially with plenty of minerals, will get your body to let go of water.
If you haven’t been sleeping well, or consume lots of sodium without plenty of other minerals before your fast, that could contribute to holding onto water as well.
Weight is not a determination of doing the fast “right”, so try to toss that out of your head. Your body could be holding onto water if it is accustomed to that - the body isn’t stupid, so it tries to retain water to protect you if it thinks you are in some sort of danger. Generally people say you lose about 2 kg a day, but that’s such a generalization given that we all have different bodies and begin at different weights. That’s why it’s beneficial to focus more on the inches you’ve lost versus the weight. People get so stuck on weight without realizing that half of the weight lost with dry fasting for example is just water weight and will return. Fat is what you want to lose.
My advice is to abstain from the scale and continue fasting. You’ll see the results and that is far more important than what a number tells you. Don’t get stressed about that when it’s always fluctuating as is - losing the fat is far more significant. Good luck 🙏🏻
If you stress out too much your cortisol will be all over the place. The dry fasting is already a stress for your body (beneficial but a stress still) so you really need to relax in order to burn fat. Then maybe you take any anti-depressant ? I know from ewperience that I could not lose anything while I was on a specific one (even though I was fasting with success before the medication). And lastly you can buy ketone strips and see if you have excess ketones in your urine. If so then you are burning fat and you can be reinsured that everything is going well even if the scale fluctuates. I think (don’t take it as an offense) that maybe you are not ready for dry fasting especially for weight loss. Cole robinson said don’t go dry if you are scared to see the scale skyrocket. I myself had swings of 8 to 10 pounds after refeeding and rehydrating but I don’t panic. I would stay on water (with electrolytes) fasting if I were you and go more on an intermittent schedule (why not dry). Good luck !
