I had stopped eating them for a while. As far as I know, they used to cause me no issue.
Now that I've reintroduced them, I feel fatigued whenever I eat them. I've tested just eating yolks. I always get a bit of white, but it's mostly just yolk. Even then I feel brain fog.
1. Anyone else have eggs do this?
2. Is there a way to rebuild my ability to eat eggs? I'd rather not have to avoid them.

Okay, wow, bit of research points to a theory here. Leaky gut = avidin, from egg whites, binding to biotin. Biotin readily crosses the blood brain barrier, but my best guess is the brain wouldn't use bound materials. Too many membranes, chemical lock key systems, etc. What would happen instead is you'd get a localized deficiency in biotin - which is linked generally with poor cognition, depression, lethargy (and motor issues and psychosis at extreme levels).
If you check wikipedia, you'll find that egg whites on there own can cause such symptoms, but normally after a LOT of exposure:
But if we throw in "leaky gut" (a damaged gut membrane that allows anti-nutrients into the body itself), and imagine this bound biotin wasting the BBB transport space for a little while, and not being used, we can easily imagine a temporary, localized deficiency in biotin.
The solution of course being the same as all leaky gut protocols - avoid all anti-nutrients for a while, and down the bone broth regularly (I used bone broth in stews for about a year for my issues).
I've heard Poliquin say that you can reset sensitivity to eggs by excluding them for 6 weeks, then eating them again. Sounds like nonsense to me but there you go. Personally I like eggs but they tend to cause stomach drama.
Choline in eggs usually enhances mental focus. But if you have a strong response to anti-nutrients (how do you do with nuts and seeds? grains?), you may have leaky gut, and need to follow a bone broth protocol for a while and avoid all anti-nutrients. (If your gut has been worn down, the anti-nutrients can get into your system, which produces an immune reaction. The protocol for that is designed to heal your gut, so that it stops happening). You can get choline from beef liver, as an alternative, and that while not so tasty on its own, is beutiful in a home made pate.
Egg whites are known allergens - the avidin they contain is their anti-nutrient. Cooking the whites well should disable it, but some folks are allergic to them anyway.
Typically when they ate toast with eggs sometime in the past, the gluten in the barley or wheat signaled zonulin, which caused the gut barrier to open up (a temporary form of leaky gut), then, egg white protein made it across into the blood, and the autoimmune system marked it as an invader - so now you have an allergy to the whites.
Part of the problem is that brain fog is usually a symptom of the blood-brain barrier being leaky - the same way as the gut lining, because it consists of the same types of cells. So your number one priority is to avoid all eggs temporarily until you can heal both your leaky gut and your blood-brain barrier.
You can do this with bone broth - a cup or two a day, and also L-Glutamine (buy it as a powder not as a pill), take something like 5g-10g a day. You can test your blood brain barrier with GABA. If you feel very calm right after you take GABA, you have a leaky blood brain barrier. You'll also want to avoid fermented foods as its flora can also make it past the leaky gut and into the bloodstream.
The brain fog you feel may actually be the autoimmune system attacking not just the egg protein, but also your brain cells, so this is a pretty serious situation. It's the same type of thing that happens if you get brain fog from eating gluten. So, whatever you do, please avoid the stuff for at least a few months before you attempt to reintroduce it.
How do you do with wine / broccoli / garlic / onions? Eggs are a good source of sulfur, which could maybe cause brain fog if you're unable to process it well.
If you have an allergy or sensitivity to them, they can cause brain fog
No brain fog here, sorry I can't offer any advice on that. However, I do find that since eggs are quite low in energy (only about 70 calories each) if I only eat a few of them as a primary meal, I will be extremely fatigued and low on energy. I noticed that eating several of them (at least 4 at a time), along with plenty of fat, makes a much more substantial meal and usually eliminates the fatigue issue in my particular case.
