Intermittent Fasting/Time Restricted Eating

Regardless of territory or religion, different ancient civilizations used intermittent fasting and were fully aware of its effectiveness.
In ancient Indy, Greece, and Egypt, the ancients used intermittent ‘fasting’ to treat certain diseases, but also as prevention.
They used it to strengthen the body, as intermittent fasting kicks off a set of processes in the body, as the release of more Norepinephrine, an organic chemical in the catecholamine family that functions in the brain and body as a hormone and neurotransmitter, giving the person practicing the fast more energy, alertness, and focus.
Even before the ancient Egyptians, Greek and Hindu, due to food scarcity our ancestors, hunter-gatherers, practiced intermittent fasting. Before agriculture, people ate what they could hunt when they returned home empty-handed, and wild berries were nowhere to be found, periods of starvation took place, and this greatly strengthened hunter-gatherers.

If we take a look at the history of different religions and their connection with intermittent fasting, we find how Judaism has several annual fast days including Yom Kippur, the Day of Atonements; in Islam, Muslims fast during the holy month of Ramadan, while Roman Catholics and Eastern orthodoxy observe a 40 day fast during Lent, the period when Christ fasted 40 days in the desert.

A study, published in the journal Cell Metabolism details advances made in the research of mitochondrial connections and explains how intermittent fasting is crucial to increase lifespan. According to the researchers, dietary restriction and intermittent fasting have shown in the past to be able to help health during the years of old age, so understanding why this phenomenon occurs is a crucial step towards the therapeutic use of its benefits.
