Fasting is normally associated with religious devotion as described in this article: https://www.lds.org/general-conference/1986/04/the-law-of-th...

However, even while describing the spiritual benefits of fasting, this LDS leader also points out what science has said about the benefits of fasting:

"Fasting is also beneficial to us physically. Some time ago I read an article in Science News written by Charles L. Goodrich, which stated that the advantages of modern eating habits extend far beyond the cosmetic. Numerous animal studies have demonstrated that caloric restriction early in life leads to an increased life span and reduces the risk of certain diseases.

"There is also evidence of health-promoting effects of periodic fasting. Some experiments have shown that periodic fasting not only promotes a longer life, but encourages a more vigorous activity later in life."
