Fast (or Fat-Fast) Until Noon
Andrew Huberman is a proponent of fasting as a way to improve cognitive function. He engages in a practice of fasting until noon to increase levels of epinephrine in his body. He explains that when epinephrine is within its optimal range, it can increase focus and learning capabilities. Huberman also suggests that fasting can improve overall health and longevity, but it's important to consult with a healthcare professional before making any significant changes to your diet.
