Our gut is often called our ‘second brain’, and so if fasting can help this second brain heal, imagine what it can do to your actual brain, too!
Some studies have indicated that intermittent fasting could improve cognitive function, by regulating inflammatory markers caused by internal (food) and external (work, workouts) stress.
Ketones, which are produced during longer fasts and while following a low-carb, high-fat diet, have been shown to play a neuro-protective role by improving metabolic efficiency, supplying more energy, and providing energy at a faster rate to both your brain and body.
One study even showed that fasting can protect against cell damage and death, which supports longevity through a healthier ageing process. One thing we know for certain is that fasting does increase the production of brain-derived neurotrophic factor (BDNF), a protein that increases the resistance of neurons in the brain to dysfunction and degeneration, again aiding longevity and healthy ageing.
Try fasting for around 12-14 hour per day for the next 4-weeks and combine this with a reduced sugar and carbohydrate intake, you'll quickly notice the difference.
