The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
But it is the case that for most people, meaning people who are not on a ketogenic or very low carbohydrate diet, they're not adapted to low carbohydrate diets, that neurons in their brain and body are using glucose in order to function. That's what allows those neurons to fire electrical potentials, that's how we refer to it, firing, meaning sending electrical signals down their length to communicate with other neurons.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

And I know a lot of other people have had the experience of being fasted and feeling like they have a lot of mental clarity. When you are in a fasted state, typically you are going to use fuels that are available to the neurons, based on your intake of food the day before, maybe you're using some glycogen, maybe you're using some fat, maybe you're using some blood sugar, that's derived from other storage sites in the body. You don't actually use fat as a fuel source for neurons under typical conditions.
