Low Potassium and Heart Conditions - A Possible Concern for Keto & Fasting

Recommended Posts

We've written elsewhere that potassium is a concern for strict ketogenic diets, in particular with athletes, and presumably also with fasting. We supplement with Cream of Tartar, as always, research how much you should need, and calculate where you are getting it from. But...an additional concern about low potassium, isn't just the lethargy, or cramping, if you aren't getting what you need. I can also lead to, or promote heart failure and arrest. There is lots to google here if you need, but one such study.

The idea is that the heart needs potassium to electrically fire regularly, low potassium can interfere with this, and produce clotting which can be life threatening. Basically, you just don't want to be habitually low, especially as an athlete, who sheds it in workouts. Food sources for potassium on a ketogenic diet (avocado, spinach, etc), can help, but could become repetitious, and one can lose track of how much potassium one is consuming regularly.

We had this discussion before but just to bring it up again. I was low carb, had runny tummy, it was summer and I sweated a lot and found myself having intense chest pains. Felt like my heart was pinched, I was exhausted and very very uncomfortable. When my heart cramped again a friend took me to the ER, they admitted me checked me and when tests came back it said all good except low on potassium. Not super low, just low. I got a powder and felt like new within 30 minutes. I wanted to supplement potassium to avoid this in the future but no pharmacy would sell me without prescription and my doc refused to give me one as a new blood test showed potassium back to normal. As too much potassium is as dangerous as too little apparently. From my experience checking kidney and electrolytes seems like it's a sensitive balance, I was recently slightly low again, had more avocados and salt and it went back up within three months.

What I found a little interesting was the story that I guess consistently low potassium might actually produce blood clots in the heart. Meaning, not just presenting an immediate issue of lethargy, or cramping, but something that could conceivably be life threatening, on delay. The clot could form, and then be pumped out, and produce a blockage later.

This is pretty upsetting. I haven't had time to read more than the summary, what was the cause of their low potassium levels? 

And would this not support the idea of eating a all-round nutrivore diet rather than diets eliminating food groups?

    • I found Peter Vail's dissertation again. Unfortunately, he does not cite the Burmese Chronicle: Vail repeats the omission in his article: MODERN "MUAI THAI" MYTHOLOGY.
    • Every injury is different, but a big part of my approach has been warm water massage, especially for shins, and to not use rest too much. Instead, active recovery:     You can also read this article I wrote a few years ago, which details my injuries and some of how I responded to them:  Large and Small – The Injuries and Ailments I’ve Had Fighting in Thailand
    • Hello to all the Nak Muay. I have been practicing Muay Thai for few years, I have always admired those fighters able have a strong body/stamina when come to practice and fight. So few years back then, I tried to register a semi pro fight, it is a great and worst experience to me throughout my life hahahah, I enjoyed and suffered a lot during the process. Since I was not a great athlete and my first time. I get a lot of injuries/sprain throughout my training, which lead to my main topic here, how did you recover/ heal your injuries during the training and post-fight? I had been carrying the injuries for few years and I went for few acupuncture sections and massage. It partially help, but does not fully recover from how I used to be. The injuries limited my strength and movement and became a burden even a stretching. Please kindly advice/share me your experiences, I wish to get rid of it.  Thank you 😊

    • Great Step Taken. I would always admire Lumpinee as an inspiration!!!
    • I wanted to comment on this theme of MMA in regards also to what Kevin said on your last Muay-Thai Bones Podcast ep 26. Kevin spoke that he felt a red line had been crossed by allowing MMA in Lumpinee. He said He didnt want inferior MMA being shown there as one reason. He spoke of the inferior MMA of One Championship as compared to the UFC. Though the pool of fighters in One is smaller, it has for instance Team Lakay from the Philippines, and the Lee family of Hawaii:  Angela, Christian and now Victoria who could be champions in the UFC too, The UFC is best at exploiting and ruining the lives of its fighters who are subject to terrible contracts and endless bullying by this massive corporation.  Thank God One Championship exists, and many thanks to Chatri Sidyodtong for bringing Muay-Thai and Kickboxing into the program in 2018. The real problem of having MMA in Lumpinee is the problem of MMA itself. MMA usurped MuayThai years ago as the premier fighting art. In the early 90s when they had the first cage fights, it was also a contest of which style would prevail. Unfortunately BJJ 🤢 was the winner in those early years. Muay-Thai was only useful in standup, and striking could only prevail on the feet. If the fight went to the ground grapplers would prevail. Wrestlers, judokas jui jitsu, and sambo fighters could easily take down a stand-up fighter and submit or choke him out.  A third point which makes MMA the most attractive art is the streetfighting aspect which makes it more "realistic" to the bored average Western viewer. So MuayThai is seen as only one part, -and a less important aspect of MMA😢. What I am getting at basically is that from a Muay-Thai standpoint it would be better if MMA:                                         A) Never existed, or                                         B) Would just go away!😈
    • It was just announced that, starting January 8th of next year, Lumpinee will start promoting an afternoon show that is only children. There will be 4 bouts per card, starting at 1:30 PM. Children have been permitted to fight at Lumpinee for a long time, but there has always been a weight limit (and ostensibly an age limit, but I'm not sure what that was; the weight limit kind of takes care of the age limit at the same time) of 100 lbs. As it's been told to me by Legends and older fighters who entered Lumpinee at that 100 lbs minimum, it's a bit of a forgiving line and fighters sometimes had to eat and drink in order to try to hit 100 lbs, rather than anyone dropping down to it. This new show is lowering the weight limit to 80 lbs, which will allow younger fighters or will at least acknowledge what weight some of those fighters are actually at when they come to the stadium. The intention of the show is to give access and opportunity to dao rung or "rising stars" as they are called in Thai. It's unclear from the announcement who will be the promoter for this particular program, but it's in line with something that Sia Boat of Petchyindee had initiated and invested in for his own promotions prior to the most recent shutdowns from Covid. It is unlikely that this will include girls; but we'll see. Of note is that the graphic used for this announcement are two young fighters Jojo (red) and Yodpetaek (blue), two top young fighters are 12 and 13 years old, who recently fought to a draw on a high profile fight. Neither of these two fighters meet the weight requirement at 80 lbs.
