Certain animal studies conducted on mice and monkeys have shown the benefits of a low-calorie and nutrient-rich diet in extending life expectancy.
Now, recent studies suggest intermittent fasting might be the key to longevity.
Scientists have understood the role played by the growth hormone IGF-1 and how lower levels of this hormone is the key to a long life.
The IGF-1 hormone stimulates growth and makes the cells reproduce. While this is good when we are young, lower levels of this hormone offer protective benefits as we age. A high level of IGF-1 fastens ageing and age-associated diseases.
Scientists have found that IGF-1 levels can be lowered by fasting. Further, when our bodies do not have access to food, they go into repair mode in the place of growth mode, which is why researchers advice calorie restriction to live healthy and long.
