While both “Intermittent fasting and exercise provide neuroprotection from age-related cognitive decline,” which has the biggest effect on our brain health? New research published in The Journal of Physiology compared 90 minutes of light cycling exercise to six minutes of high-intensity cycling intervals and found that the brain health benefits increased by 4-5 times when doing just six minutes of high-intensity cycling intervals. Additionally, the short six-minute intervals had a more impactful effect on brain health compared to 1 day of fasting with or without prolonged light exercise.
