If you follow my work and message, you know that I’m a champion of brain-derived neurotrophic factor, or BDNF. A protein that plays an integral role in stimulating the growth of new brain cells, and the performance of existing neurons, BDNF is best described as the brain’s “growth hormone.” Given that, stimulating the production of BDNF is easily one of the best things you can do for your body and your brain. One of the ways I recommend doing that is by engaging in intermittent fasting. If you’re looking to incorporate fasting into your regiment, I recommend fasting once or twice a year for 24-48 hours at a time. As hard as it may be, during this time you must cut out everything except water (which you should drink plenty of). Remember, fasting may be a stressful activity, but it’s one that acts as a very positive stressor for your body, as it instantly activates life-altering genes. Of course, before engaging in any type of fasting, you should consult your physician.
