Brain Fog Eraser: High-Quality Protein
The speaker argues that brain fog is not a vitamin deficiency but a post-carbohydrate hypoglycemic crash. When you eat carbs, blood sugar spikes then falls, leaving you mentally foggy. A dose of high-quality animal protein—he specifically names red meat or a hamburger—provides amino acids and stabilizes blood sugar almost instantly. He contrasts this with taking vitamins, which he says is ineffective for this purpose.
brain fog comes from a hypoglycemic situation where your blood sugar is low because you ate some carbohydrate previously … taking more vitamins is not going to help you can consume high quality protein and within maybe a minute your brain is feeling good
