We all know how important the electrolytes are during fasting, as well as the ratio between them. Eg Potassium to Sodium 2:1 ratio. Many drink water with salt and potassium.
I just stumbled upon this NIH link and can’t vouch for this device - maybe others on this reddit can look into this device and help everybody. Would also be awesome to have a device for Magnesium and all 7 electrolytes. Personally I don’t have any background to be qualified to properly look into such devices:

Self-Monitoring Device of the Urinary Na/K Ratio, because “measuring the mean values at the clinician’s office… may not provide prompt enough feedback for the patients to make further dietary modifications.”
“Nowadays, urinary Na/K ratio can be measured by a portable self-monitoring device (HEU-001-F, OMRON Healthcare Co., Muko, Japan). This device measures urinary Na/K ratio by the ion electrode method and displays the result within one minute. Since this device provides prompt onsite feedback in personal use, it became evaluated in randomized control trial with a view to support an individual approach for Na reduction and K increase.”
Also at home blood test kits, as well as urine kits. Would be great to know which are best to use frequently. Drawing blood from finger or any part of skin that is out of the way.
For all sorts of key indicators during and after fasting to guide intakes of nutrients more precisely.
