So I do a keto diet and generally eat around 4-5g of sodium per day which works out pretty well.
Day 1 of fasting I had way too little sodium during most of the day and had more later and during the night, had a lot on day 2 (3-4g) but it still wasn’t enough.
So I had about 4-5g on day 3, but that was too much (excessive thirst, waking up thirsty), so I had about 2.5g today but it still feels like too much.
My question is, did my under supplementation on day 1 throw my body off and cause it to hold onto more salt? Does anybody know how sodium excretion works?
Usually if you pee excessive when drinking average daily water (2-2.5 litres for average person if they don’t exercise) then that’s a sign of low sodium
If you’re drinking plenty of water but you feel bloated, or water retention in the legs and feet. That’s a sign of too high sodium.
With this in mind, if you sweat excessively. (For example, via exercise or sauna use) this will drastically lower your electrolyte levels. This is because when your body releases sweat, sodium is released with it.
This is my advice. If you don’t exercise or sweat a lot. Stick to 2-2.5 litres of water, if female maybe just 2 if large male probably 3.
Add salt to each meal you eat, if you only eat once or twice a day then don’t add a load salt but a normal amount. To make up for the fact you may not eat 3-6 times a day then add salt to your water. Preferably 1 gram for every litre.
There are a lot of variables so if you would like to input more info in terms of your diet, frequency of meals, litres of water, exercise/sweat levels. I could give some more advice
