  • There’s evidence that taking breaks from food – in the form of either FASTING or CALORIC RESTRICTION — may help protect the brain against Alzheimer’s, Parkinson’s and other conditions.
  • Both short and extended fasts have been shown to promote neurogenesis, and to clean mis-folded proteins from the body and brain.
  • As a side note, fasting has been shown to dramatically increase the life span in both animals and insects, in laboratory studies.

  • I started fasting a couple of years ago because I was experiencing some health issues (I was feeling sick and low energy, with no obvious cause).
  • My health, and feelings, improved radically once I started fasting.
  • Some people may find it hard to start fasting, if they normally eat a diet high in carbs. I find it easy for the most part because I usually eat a ketogenic diet. (People on ketogenic diets are using ketones, not glucose, as a fuel, so don’t experience sugar cravings.)
  • I’ve tried different fasting regimens. I’m currently fasting 60 hours a week (from Sunday night to Wednesday morning).
  • I find going without food for two days (and three nights) every week to be an easy way to get in some fasting and autophagy, which is also very good for the brain.
  • If you’re new to fasting, or have health issues that might make it a bad idea, I recommend reading Dr. Jason Fung’s book, “The Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting”, or watching some of Dr. Fung’s videos, before trying it.
