I am 21F, height 160cm, starting at a slightly overweight BMI by the WHO standard for Asians. I fast for fat loss and efficiency. I have done a 7-day waterfast several years ago and am dabbling in dryfasting now. I have tried to dryfast for several times but often ended up cheating on them. That’s why I am a little bit proud of myself that I have finally succeeded in doing a 40h hard dry without consuming anything (food or water), though I know it’s nothing at all compared to what many of you do.

Feel free to have a look at my progress :) Hope I will remember to keep updating it.
Questions for my fellow fasters:
Is it normal to only output a small amount of urine when dryfasting?
Does (the dehydration from) dryfasting harm the kidneys? Has anyone monitored their kidney function across dryfasts? Please share with us.
I am scared of frying my kidneys to just lose a few percent of body fat. I may report back if I do decide to do a kidney function test, though there won’t be a recent baseline before dryfasting for comparison.
Feel free to ask me anything too :)
Supposedly your kidneys are required to do less work during a dry fast than a water fast, so that it is easier and more restful for them.
The idea of a water fast is to “flush” the toxins out of our cells with lots of liquids. That means lots of poisonous substances passing through the kidneys, possibly damaging the kidney cells in the process.
The idea of a dry fast is not to do that very much at all, but to try to “incinerate” or digest or oxidize most of the toxins, within the cells, via the activity of lysosomes.
Perhaps Filonov could speak about what happens when people with pre-existing kidney problems conduct a dry fast. He has supervised many people dry fasting for years, and his book is now translated into English and he’s on youtube I think also.
