There’s actual meat to this. I’ve been digging into the neurobiology side of things, and researchers like Mark Mattson have published extensively on how time-restricted eating triggers ketone production and boosts BDNF. It’s not magic. It’s basic cellular stress response. When you strip away the constant glucose influx, your brain stops running on autopilot and starts optimizing. I’ve noticed it myself. After a 16-hour window, my mind feels sharper. Less mental fog. It’s like the static clears.

From a psychological angle, it tracks with Carl Jung’s idea of symbolic withdrawal. When you voluntarily restrict something as fundamental as food, you’re forcing the ego to step back. That creates space for deeper patterns to surface. In tarot, this is exactly The Hermit energy—solitude, inner guidance, turning away from the noise to find the spark within. Fasting isn’t just about losing weight or "cleansing toxins." It’s a cognitive reset. You’re removing the sensory input so the underlying structure can emerge.

That said, I’m not saying everyone should jump on the intermittent fasting bandwagon. I’ve read enough about disordered eating triggers to know this works differently for different people. My experience is pretty straightforward: when I fast, my rune readings feel less cluttered. The symbols don’t bounce around in my head. They settle. I think it’s the combination of lowered insulin spikes and that mild ketotic state quieting down the default mode network.

Has anyone else noticed a shift in their divination or dream recall when they experiment with eating windows? Or do you find that hunger just makes you irritable and scattered? I’m genuinely curious how this lands for the rest of you.
