Slight brain fog - what could be the problem?

by 108 · March 31, 2013 at 06:52 PM

Hello!

Eating paleo for 2,5 weeks now. The only exceptions I had were a couple of beers from time to time. I feel good and have enough energy to do pushups and a bit of weight lifting. But for a while now I experience brain fog and it scares me a little. I measured my blood pressure and it was good.

The first to weeks I ate low carb. Now (for about 2,5 days) I raised the carbs with sweet potatoes, fruits and stuff. But I still have a clouded head and sometimes walking feels a bit floaty (mostly after eating something).

I have to admit that one day I felt cloudy, that it scared me a little, so I bought a small bun. Not paleo at all, i know, but sometimes I'm scared I could faint.

I think about seeing a doctor. Any ideas?

cheers Marc

Low-carb may bring this, if you're not fully adapted to using fat as fuel you could go a little bit hypoglycaemic which will bring on the feelings you describe. Be sure you are adding enough protein and fat (not overdoing it BTW be careful with this...) plenty of water and check your salt intake, low carb means lower water retention so it could have something to do with it.

Also, if you had some thyroid issues it's most likely that will manifest while dieting as you are most susceptible to energy imbalances.

Wouldn't hurt to do some blood test in order to check that everything is ok.

You don't tell if you have been overweight in the past or if you do some sports/exercise, that would give some insight.

I'd advise to be very carefull about lowering the carbs too fast and start with getting rid of the crap and then go easier with tubers/veggies/fruit (you already did this when feeling bad) and maybe even white rice until you feel OK and can get to less amounts in small stemps until you don't notice any brain fog or other issues.

Hi Marc -

I went from a "natural food" diet (limited processed foods but plenty of carbs, wheat, etc) to a VLC paleo diet in one step. I was suffering from severe heart burn and I read on Chris Kresser's website that VLC would help. I lost some weight and the heart burn went away, but the strange brain fog as you describe appeared. I've been low carb for 3 years now, and the fog has slowly gone away. I remembering being 6 months into my Paleo change and still wondering if the brain fog was a serious health problem.

As Albert mentioned, I suspect that it has to do with the body not being fully able to process fat for energy, but that is pure conjecture on my part. I found that sleeping more each night helped, as well as fasting in the morning. However, nothing truly made it go away. I hate to say it but it was nearly 24 months before I noticed that I wasn't mentally running at "half speed" anymore.

If I could do it all again, I would measure some data to try and pinpoint the causes. Such as measuring the amount (and quality) of sleep each night, and also testing myself with some simple multiplication problems or something similar to try and quantify my mental slowness.

In short, hang in there, it passes over time; but in my case time moved very slowly.

I agree with raydawg that one possibility is the beer. And if you use any store-bought flavoring agents you can't rule out adulteration there either.

I can confirm that it only takes a trace of wheat to put me in a fog and then I have to go over everything I've eaten or drank lately to try to figure out the culprit.

Another possibility is if you're lactose intolerant, just like wheat an amazing number of store offerings have milk-based ingredients and that does the same thing to me.

Are your foggy times happening during the same time of day? Or while you're digesting food? Keep mental notes or a diary for a week or so to see if that gives you any clues.

One final thought--I was feeling so good recently that I was tearing my place apart and cleaning and re-arranging. I suffered a sudden energy crash that liquid didn't help but a banana solved instantly. So, you could have an imbalance in electrolytes or vitamins or something.

One thing that sticks out is the beer. Sorry to say, but most beers will have some gluten. It might be enough to give you some of the side effects such as brain fog. This isn't 100%, just a suspicion.

Gluten seems to be one of those proteins that is very short and its amino sequence looks like a lot of our tissue to our immune system. Brain fog is one of the symptoms of this.

When I switched to more pure alcohols such as tequila, vodka, and whiskey, I found I could drink a lot more and get far less of a hangover.

You could, of course, not yet be adapted to burning fat, and are experiencing the symptoms of both not having enough ketones and glucose, so your brain is suffering. If this is the case, try a week or two of very low carbs and start the mornings with something like bulletproof coffee, or some other thing with coconut oil in it. Careful with it, start with a few teaspoons at a time of coconut oil - if you try to get a tablespoon at once when you're not yet ready, you'll find yourself visiting the bathroom for explosive elimination sessions. So sip, don't chug.

The coconut oil is about 50% MCT (Medium Chain Triglycerides) which your liver will quickly convert to ketones which can fuel your muscles and your brain. Avoid all carbs when you do this until about dinner time, or at least lunch.

If you're having a hard time digesting the fats and are impatient you can get a bit of digestive enzymes that contain ox bile - this is optional. On the other hand, if you've had your gall bladder removed, you must consume digestive enzymes before any meal containing fats and protein as you no longer produce enough bile to process fats (that's a problem I have.)

The point about choline is a valid one, even without racetams. It's a good idea to have some if you're consuming saturated fats (the other half of coconut oil.) You can get some from egg yolks, or a good quality pastured liver. Or in the absolute worse case soy lecithin (though you're better off with a sunflower lecithin first.)

Little update: I am really thinking about quitting the whole paleo thing, because the dizziness/brain fog I get from foods is not acceptable and it's kinda unsettling. I am already scared to walk somewhere because I could faint or just suddently feel that way again.

Today I had a dish with parsnip, celery and onions. This contains carbs, right? It made me dizzy too (after about 20 minutes later). I feel like a drunk person now. It seems the paleo-experiment totally disordered something inside of me. I feel like I should see a doctor soon.

Could be a low level of choline? When I was experiencing brain fog I did a few things to help with it and have continued taking it since it seemed to help. I've been taking Piracetam, Neuro Wave, and CDP choline to help with my brain fog.

Piracetam is a chemical of the Racetam family class that stimulates the GABA and ACh receptors in the brain which play crucial roles in how memories and thoughts form. Neuro Wave, is Aniracetam and primarily focuses on stimulating the AMPA receptors which are also used and implicated in thought and memory processes. CDP choline is supposed to help replenish the choline that the two racetams will be using, but has a side benefit of stimulating the dopamine receptors which adds a mild mood elevation to the stack.
