Intermittent fasting and longevity

by - April 14, 2019


Intermittent fasting and longevity are closely related concepts. Increased longevity is one of the immense benefits you stand to gain health wise through intermittent fasting.
In this article, we will be looking at ways by which intermittent fasting affects longevity.

Intermittent fasting is the deliberate abstinence from food for hours at a time. During this time, the person takes in little to no caloric foods except water, and other non-caloric fluids. The hours during which the person doesn't eat anything is called the Fasting Window while the period/hours during which the person eats within specific hours is called the Eating Window.

Intermittent fasting has been proven to aid in renewal of cells also called Autophagy, affect metabolism rate, helps fight cancer, helps in treating type 2 diabetes, helps in weight loss, etc. It also helps you to groom your mental strength. As many times, we really aren't hungry when we eat, we just have an emotional attachment to food. So, Fasting helps to train your mind and emotions to cope without food.

So, how does Intermittent fasting affect longevity/life span?

Intermittent fasting has been shown in numerous studies to significantly slow down the ageing process. Scientists are yet to understand fully, why this is so.

Intermittent fasting has been proven to manipulate mitochondrial networks inside the cells. This may help to increase lifespan greatly and promote good health. This study was done by the Harvard T. H. Chan School of Public health and it was published online on www.cell.com. The study was based around cell metabolism and why cells decline in their ability to break down energy with time.
They found that apart from intermittent fasting, genetic manipulation of Proteins could also manipulate mitochondrial networks.

 You might be thinking, "What really is a mitochondria?". Well, mitochondria is the power house of the cell, it is the energy producing structure in cells.
These mitochondria exist in networks that change their shape with the type of energy demand it receives. The mitochondria's ability to do this reduces with age.

These scientists used the nematode worms called C. Elegans to experiment. These worms live for just two weeks normally. So, they found that by restricting the worms' food/diet, or by manipulating a particular protein genetically, the mitochondrial networks remained in a youthful state past their normal lifespan. This clearly shows that Intermittent fasting can effectively slow down the ageing process which is a normal stage for most living organisms.

These findings are a huge step forward. This means that through intermittent fasting, the number of age related diseases of old age can be reduced. Apart from studies carried out on nematode worms, similar results have been obtained from studies on mice, yeast and even mammals like Monkeys.

Intermittent fasting helps to improve the functions of cells that are aging. Intermittent fasting improves tissue function, metabolism rates and reduces stress.

Since intermittent fasting reduces the risk of developing various diseases like Cancer, high blood pressure, heart diseases etc, then it indirectly helps to lengthen a human's lifespan because, the lesser the number of diseases a person gets, the lower their risk of untimely death.

Intermittent fasting, in conclusion, is very beneficial to people as it helps to increase longevity or lifespan.
