The Bible presents fasting as something that is good, profitable, and beneficial. The book of Acts records believers fasting before they made important decisions (Acts 13:2; 14:23). Fasting and prayer are often linked together (Luke 2:37; 5:33). gotquestions.org
Fasting cleanses the soul, raises the mind, subjects one’s flesh to the spirit, renders the heart contrite and humble, scatters the clouds of concupiscence, quenches the fire of lust, and kindles the true light of chastity. Enter again into yourself. St AugustineO you who believe fasting is decreed for you, as it was decreed for those before you, that you may attain salvation. Specific days (are designated for fasting); if one is ill or traveling, an equal number of other days may be substituted. Those who can fast, but with great difficulty, may substitute feeding one poor person for each day of breaking the fast. If one volunteers (more righteous works), it is better. But fasting is the best for you, if you only knew. Quran 2:183-185
In Buddhism, fasting is recognized as one of the methods for practising self-control. The Buddha advised monks not to take solid food after noon. Lay people who observe the eight Precepts on full moon days also abstain from taking any solid food after noon. Critics sometimes regard these practices as religious fads. Budsas.org
For one who is fasting, the sense-objects disappear, Leaving the yearning behind. Bhagavad Gita 2:59
Fasting for regular periods could help protect the brain against degenerative illnesses, according to US scientists.
Researchers at the National Institute on Ageing in Baltimore said they had found evidence which shows that periods of stopping virtually all food intake for one or two days a week could protect the brain against some of the worst effects of Alzheimer’s, Parkinson’s and other ailments.
“It is likely to be better to go on intermittent bouts of fasting, in which you eat hardly anything at all, and then have periods when you eat as much as you want,” said Professor Mark Mattson, head of the institute’s laboratory of neurosciences, and professor of neuroscience at the Johns Hopkins University School of Medicine in Baltimore, told the annual meeting of the American Association for the Advancement of Science in Vancouver.
He and his colleagues have also worked out a specific mechanism by which the growth of neurones in the brain could be affected by reduced energy intakes. Amounts of two cellular messaging chemicals are boosted when calorie intake is sharply reduced, said Mattson. These chemical messengers play an important role in boosting the growth of neurones in the brain, a process that would counteract the impact of Alzheimer’s and Parkinson’s.
“The cells of the brain are put under mild stress that is analogous to the effects of exercise on muscle cells,” said Mattson. “The overall effect is beneficial.”
This model has been worked out using studies of fasting on humans and the resulting impact on their general health – even sufferers from asthma have shown benefits, said Mattson – and from experiments on the impact on the brains of animals affected by the rodent equivalent of Alzheimer’s and Parkinson’s.
Mattson said that a person could optimise his or her brain function by subjecting themselves to bouts of “intermittent energy restriction”. In other words, they could cut their food intake to a bare minimum for two days a week, while indulging for the other five. Robin McKie, Science Editor: guardian.co.uk
And here’s something else: fasting for 3 days regenerates the entire immune system.
Fasting for as little as three days can regenerate the entire immune system, even in the elderly, scientists have found in a breakthrough described as “remarkable”.
Although fasting diets have been criticised by nutritionists for being unhealthy, new research suggests starving the body kick-starts stem cells into producing new white blood cells, which fight off infection.
Scientists at the University of Southern California say the discovery could be particularly beneficial for people suffering from damaged immune systems, such as cancer patients on chemotherapy.
The researchers say fasting “flips a regenerative switch” which prompts stem cells to create brand new white blood cells, essentially regenerating the entire immune system.
“It gives the ‘OK’ for stem cells to go ahead and begin proliferating and rebuild the entire system,” said Prof Valter Longo, Professor of Gerontology and the Biological Sciences at the University of California.
“And the good news is that the body got rid of the parts of the system that might be damaged or old, the inefficient parts, during the fasting.
“Now, if you start with a system heavily damaged by chemotherapy or ageing, fasting cycles can generate, literally, a new immune system.”
