What is brain fog?

I recently interviewed 6 brain health experts (all with different backgrounds) to figure out what brain fog really means.

I suffered from severe brain fog for 5+ years before finally healing myself. Now I help others go from foggy to fit.

The term ‘Brain fog’ casts a pretty wide net. It’s kind of an umbrella term for a lot of different things happening at the same time.

Summed up in a sentence, I would say brain fog is:

The brain’s inability to function optimally (as if you are living in a sluggish fog) due to many different potential factors including leaky gut, plaque build-up, mold and other environmental toxins, poor lifestyle choices, a cognitive overload of stress hormones, and many other variables.

Haha, one of the broadest explanations ever 🙂

Boiled down even more, it’s simply your body telling you that something is off.

When you feel brain fog, that means it has most likely been slowly developing for weeks, months, even years.

The accumulation of toxins and insufficient rest and detox time allows your health to pass this threshold, thus presenting the more present symptoms of brain fog.

Like many things in life, you must remember that everybody’s brain fog symptoms, causes, and solutions will most likely be different. No brain fog journey is the same.

Brain fog has some common themes such as:

  • Forgetfulness
  • Fatigue
  • Cravings
  • Low energy
  • Fogginess
  • Lack of visual clarity
  • Lack of mental clarity
  • Inability to focus
  • Sluggish thinking and precessing
  • Broken thought pathways (losing train of thought)
  • Reality separation
  • Stress
  • Frustration
  • Depression

Add these all up (and more) and that was pretty much my life for 5+ years.

It’s as if the brain (and body) is running at about 15 – 25% capacity instead of 70–100% like it could.

I’ve talked to many people that experience similar symptoms. You can hear those stories inside of our group, along with guidance, resources, and support.

I’ve also talked to experts who have talked to or helped many more people.

What the brain Experts say

There’s any number of different symptoms that come into it, but sleep it often a big part of it. The symptoms and the cause are broad and far-reaching. It’s one label that we put on a number of different things.

Labeling it brain fog is fine. The issues come when you go to your doctor and they look in their “book” to find medication that solves it. Hell maybe that pill works for a small percentage of people, but not for everyone. They’re going to have to work with the bigger picture.

The 86 million neurons in your brain know way more than anyone’s best guess. They know where the root cause of it actually is. If labeling it is helpful for the client, great, but to solve it, we must go way deeper.

If we ignore the subconscious mind, you do so at your own peril. The subconscious is running anywhere from 90 to 99% of your mind and life. It runs the programs of the body when you’re switched off. We know that the body is always trying to switch off because it knows that this increases the amount of time it needs until it gets its next meal (evolution).

I hope this gives you a unique look into what brain fog is. There are many different answers out there and I aimed to present a different perspective with this answer.


The above are not exact quotes but are in reference to my recent interview with Scott Robinson. I will be releasing the full interview and other interviews soon.
