So let's start by describing your symptoms. Where is the rash? Is it all over or concentrated on certain parts of your body? Does it itch? I can understand why you might not be sure which it is, a keto rash or a histamine intolerance, since symptoms of the two can be similar. I wouldn't do this. Like @Geezy said, fat is your energy. I would still aim for 70% of your calories coming from fat and 30% coming from protein (this is acheived by basically eat 1g of fat for every 1g of protein). According to Dr. Boz, on variant of a Keto rash in an inflammation caused by little "critters" living in your skin that love glucose. If you are not eating enough fat, then your body will be working overtime to convert protein into glucose through a process called gluconeogenesis. It's as if you are eating carbs. They were initially starved when you started keto, but when you decided to lower the fat, your glucose production may have went up, and these little guys got excited and started multiplying. I'm not sure if I buy that, but she makes it make sense. If you are actively losing weight and burning your body fat, these could actually have toxins or histamines stored in them, which are being released into your blood stream. Again, where is the rash? Centrally located? Or all over? Some thoughts on how to test this yourself include adding back in 50-100 carbs a day for the next 2 weeks by adding fruit. This is called an "animal-based" carnivore diet (for whatever reason, lol). But STILL EAT the eggs, steak, and whatever else you have been eating. If it's keto rash, symptoms should alleviate and you can then try again with cutting the plants out. If it's histamines I wouldn't expect any changes. For keto rash, topical steroids will help for itching and oral antibiotics with help with inflammation. To test for histamines, aim for the freshest meat possible, straight from the butcher. Grocery store meat will have been hung and aged for weeks before packaging. Avoid jerky, canned meats, etc. For histamines, an antihistamine will help alleviate the itch. So if antihistamines help, your problem leans towards histamine intolerance. If hydrocortisone cream and an antibiotic help, then it's more likely keto rash.
comment_13862I have just had one of the most harrowing experiences of my life. Starting sometime around 8/14, I started feeling weak and tired. I had no appetite whatsoever. This weakness continued on till 8/16 at which time I started to get worried. I took an at home covid-19 test...negative. Things continued to get worse. So I went to the ER in the morning of 8/17. I told them I have lack of energy and dizziness upon exertion and general malaise. So I was brought back and they did some blood work and found I was dehydrated and my electrolytes were out of balance. So they introduced some IV fluids, saline, and within 3 hours I felt much better. I figured that should have ended there, however they pointed out that my troponins were elevated, I don't know how high, they just said elevated.(which is a heart enzyme released when there is damage to the heart muscle) and which can also be elevated for other reasons. I was therefore admitted to the hospital for further testing. They did another ECG, as well as a heart echo cardiogram, and a leg ultrasound, looking for DVT and found nothing of concern. Throughout the night they gave me more electrolytes, saline (sodium), potassium and magnesium. I continued to improve. At one point I stated that I would like to go home, because I felt almost completely normal. No dizziness, no weakness.
And that's when things started getting crazy. The doc told me that because my troponins were elevated that he would like to do some more testing and keep me for observation. I declined all of that. And of course he wanted to put me on a statin. I of course declined that as well. So I was signed out AMA (Against Medical Advice). When I was signed out and just about to leave, in walks the cardiologist, telling me how much she cares about my welfare and asks if I could do one simple test just to make sure I'm OK. That would be a quick walk on the treadmill. I agreed. It was a little bit more involved than just a quick walk, but anyway they hooked up these probes to my chest for ECG measurements and took a before picture of my heart with ultrasound. Then walking on the treadmill I got my HR close to maximum, then another after picture was taken with ultrasound. The cardiologist came back in and confirmed what I already knew (after reviewing the before and after ultrasound pictures) that I wasn't going to die of a heart attack any time soon, if at all, ever.
I actually used to have a little bit of faith in the medical establishment, but after this last encounter I have lost all faith in doctors and hospitals. They are like a car salesman and I believe they will try to up sell you every chance they can.
These are just my opinions and some other individuals have probably had more positive outcomes, but most of mine have been negative with most doctors.
