Fasting is the willing, abstinence or reduction from some or all food, drink, or both, for a period of time.
During the Hail15Program it is recommended to abstain from food for 15 hours straight. An example of this would be we eat our last meal before 6pm and we don’t eat again until 9am the following morning.
There are more severe fasts and you can learn about my personal experience of fasting from food for 42 hours: Kristin’s blog post about fasting with a friend for 42 hours
"Fasting increases circulating levels of several neurotrophic factors, biomolecules that support the growth, survival, and differentiation of neurons. The result is enhanced network plasticity (critical for learning), increased stress resilience and increased mitochondria (i.e. increased cognitive energy). Fasting also reduces oxidative stress (and thus, inflammation) in the brain both by stimulating the removal of damaged molecules and stimulating production of endogenous antioxidants. [1] All of these translate to meaningful improvements in brain performance." (Source).
