• For short: Where do we have the most fat in the body? Bone marrow and brain. Bone marrow is around 70-80% fats and brain is around 60-80% fats. Wrong fats in the brain is a cause of brain fog. The brain has to have the right fats, and those fats are not in the plant oils, but they are in animal fats and in almost the perfect amounts in bone marrow.

The Cause Of Brain Fog

• Most chronic brain fog is not “toxins” or “inflammation” in the vague sense people talk about. It is starvation of the brain’s fats after years of cooked food, low-fat diets, or plant oils.

• The brain is 60-80% fat. When those fats are heated or replaced with the wrong ones, membranes stiffen and signaling slows. And therefore you get the brain fog.

The Effect Of Bone Marrow

• The most important thing: Raw bone marrow, especially from grass-fed animals, is almost pure usable fat. The brain needs those good fats for fast signaling.

• Raw bone marrow clears brain fog because it has the exact cholesterol and phospholipids the brain needs in the form the body can use immediately. Especially because they are not denatured.

• Cooked fats and plant oils do not. They are damaged, oxidized, or missing the enzymes and structure that let the brain rebuild myelin and cell membranes.

• Raw bone marrow also carries small amounts of natural vitamin A, D, K2, and the enzymes that help the body and brain store those fats without digestive issues.

Practical Use

• Eat 2–4 tablespoons of raw marrow daily, preferably from long bones.

• Make sure its never heated and scrape it out cold.

• Swallow it as is or mix lightly with raw egg yolk or a little raw cream if texture is an issue.

• Do this for around 2 weeks straight while in that time eating a no carb primal diet.

Clarity mostly returns in that time. First the fog lifts in the mornings, then focus holds longer and then memory sharpens.
