The only thing that keeps my heart palpitations and tingles away is salt. About a month ago I realized that was the problem even though all my tests came back in normal range. I use redmounds real salt. I need to keep my sodium level at least above 3500 mg or they will start up. In order to get it that high I have to add it straight to my water. Whenever I get one usually 1/8 tsp keeps me from getting another. Unfortunately though since I’ve increased my salt I’ve been dealing “get to the bathroom now!” In which it seems to be basically water. It’s like I have to choose between heart palpitations or crapping my pants. I usually hit the goals on potassium and magnesium it’s just I can’t keep my salt levels up unless I want to spend the day in the bathroom.
Salt induced diarrhea
Heart palpitations are typically Potassium related. But either way, take that salt in with meals. Are you doing 1:1 with sodium/potassium?
They usually equal about the same between 3500-4000. Yesterday I only put salt in my food and drank some bone broth, and a keto chow shake. I kept my potassium amount as usual. At night the palpitations hit. I took 1/8 tsp of salt but that didn’t stop them. I put 1/4” in an electrolyte drink. Within 20-30 minutes I was in the bathroom. But I didn’t have any palpitations. On most days everything starts out normal, but then after I start consuming liquid, it’s anything goes.
My experience is that there is a good range I can stay in. Below that amount, I get migraines and constipation; above, I get loose stools, though not really the sort of water you are talking about.
How long have you been eating a ketogenic diet? It seems that the initial stages require a certain amount of adaptation. If you are still new to this way of eating, then there is hope your body will adjust. The key is to get the right amount of sodium passing through the colon. Too little, and the colon aggressively takes sodium and water out of the stool; too much, and it leaves the stool loose or watery.
One thing to try is Morton’s Lite Salt or equivalent brand, which is 1/2 sodium chloride and 1/2 potassium chloride. That might let you cut back a bit on the sodium, while giving you a bit more potassium.
I’ve been on keto since June. Tried going carnivore in July and got the keto flu pretty bad. Felt just like I did when I got Covid. Even tested myself for it. After I got better from that I started getting heart flutters, tingles everywhere and spasms under the eyes. All I know are potassium deficiencies, but my tests all came back fine. About a month ago the problems started getting worse. One night I just put 1/4 tsp of salt straight in my mouth and the problems went away. So I started upping my salt intake. A few days after I started having this issue. I keep track of all my micronutrients and it seems I have to have my sodium intake to around 3000 by late afternoon or the palpitations start. Ive never been big fan of salt. Ive never went out of my way to put it on my food so I’m hoping it’s just my body adjusting to the large increase I’ve been adding.
Yours seems to be an unusual case. The diarrhoea would suggest an excess of sodium, but the muscle problems suggest an insufficiency of potassium. Normally, getting enough sodium generally helps regulate the levels of calcium, magnesium, and potassium, so this is strange. You may need to see your doctor about this. It may be that the diarrhoea is not salt-related but caused by some other factor. Or alternatively, it is possible that your body is simply adapting to the new regime and needs a few more months to settle down.
Keto “flu” symptoms indicate a lack of sodium. This arises because excessive insulin inhibits the execration of sodium by the kidneys, so the drop in insulin that results when we cut the carbs removes that inhibition and requires us to work harder to keep our salt intake up.
It is weird. Everything is pretty normal in the morning. Every now and then I’ll have a day where I have no issues at all. It’s like my body is purging water for a few days and then one day it’s like I’ve finally got something out that’s been clogged.
The only electrolyte that causes diarrhea in large quantities (to my knowledge) is magnesium. In fact, magnesium citrate in larger doses (still harmless) is used as colonoscopy prep.
To treat muscle cramps and palpitations many folks take magnesium. By any chance, are you also supplementing with magnesium? 
I always read that 1 tablespoon of salt causes diarrhea, many people said so… So it happens to people.
1/4 or 1/2 teaspoon is so tiny and we eat much more from our food that it seems odd and I would think about something else first… So many thing may cause it.
Potassium supplementation can cause diarrhea .
to OP: might help read up on them? but every biz who sells them wants your money LOL Google about electros you are ingesting on ‘a guess you need them’ ya know.
best way forward…dump it all.
eat real food point blank. salt to taste. if you ‘feel off more’ than eat more food and also ‘salt’ can be a key’ as we change. salt on tongue. not in water or some extra elec. drink you use.
when we ‘go off the supps’ we find us better. but we might have to walk thru some weirdo times and adapt times as we do this, but if we ‘supp cause we are just guessing’ it won’t help.
drop it all. rely on real food…THEN WE SEE WAY MORE but unless we give the eliimination and find us in it, we don’t know…again we keep guessing and guessing.
not sayin’ ya gotta do this ever, lol, but best way forward for alot of us, not all if you ain’t one of them that requires this, but and yea, we been there and had to dump it to find better way in our eating.
how long on plan? might still be adaption against some foods you are eating or ?? but if salt and these electrolyte issues ‘seem the culprit’ dump them and then re-build against what it happens for you.
don’t dump salt tho…salt food to taste. if salty like, say, eating bacon you should be fine cause we know it is sodium in there, but if basic fresh food salt to taste and take it from there.
just some advice, if it suits you to find you…wishing you the best way forward that works for ya!!
yea key being we don’t know ‘what we need’ when we guess we need it kinda??? we can get vitamin overload, cause troubles, we can get mineral overload cause troubles but IF we don’t dump all first, we kinda don’t know what do ‘we really require’ ya know.
yea I had to find this out the hard way too LOL
but if one goes to Dr. for ‘full panel’ vitamin and mineral blood test like I did, hmmm, we see who we are and can not have to guess on sucking down this electro. drink or taking extra mag for this reason etc.
it is a hard call on how one wants to move forward but elimination works best vs potass. and mag…salt nope…best we keep some in cause as we do drop carbs we drop water held in the body and our sodium IS VERY reliant on xyz sodium in the blood for best health and how less water in our bodies are controlling that sodium level.
key being ol’ days we would ingest blood thru hunting on meats and now it is not like that for us ‘in this eating world’ and we find that salt is key. salt is a very vital active thing but this potass. and mag…are way over used thru supps and more thinking ‘we need and guess’ we do but unless Dr report? do we? and things can work against us.
also how one feels. if one is ‘off’ and ‘guessing’ dump it 
find that NEW you on what ya need, the body will show us mostly.
ok just chat on it all LOL just a fun way to show others that sometimes ‘way less is way more’ for us as we find us!!
The only supplement I take is the daily mineral drops from keto chow. The full daily dose is a tbsp. It has 1000 mg potassium. 400mg of magnesium, and 600mg sodium. I usually only take 2 tsps of it but spread it out throughout the day.
I’ve been using daily minerals from keto chow since the keto flu. The problem started like two days after I started increasing my salt intake. My tingles seemed to have disappeared completely a few days ago, but I still get the heart palpitations if I don’t keep my salt intake up. I think I read somewhere that salt helps your body use potassium.
I’ve never been big on salt. I never went out of my way to put it on my food. I can only stand really putting 1/4 tsp on my food. So with that at two meals a day and maybe another 1/4 tsp if I get a palpitation that’s not even a tsp of actual salt that makes up my average of 3500 mg of sodium. But the only thing that has changed is the addition of Redmond’s real salt. When I was dealing with the keto flu I was using pink Himalayan salt. I can’t see it being some kind of reaction to the brand.
Sodium does too, I found out when I was using sodium bicarbonate to ease heartburn.
That’s an awful lot of potassium when you consider how dangerous it is to supplement with, there’s are reasons most potassium supplements are limited to 100mg.
