Fasting For Faith and Health

When I was a child it was the custom in my family and in my church to give something up for Lent. This was most often a food such as candy or soft drinks. The couple of years that I gave up candy for Lent, the candy that I got in my basket on Easter Sunday morning tasted even sweeter because I had not eaten candy for about six weeks. As a child I did not understand the spiritual implications of fasting, or that it might have health implications as well.

Fasting as a Spiritual Discipline

Fasting is a tradition in many religions including Judaism, Christianity, Islam, Buddhism, and Hinduism. In the Christian faith, the purpose of fasting is to help increase affection for God. Special fast days were a part of the Jewish calendar. Queen Esther fasted before approaching the King. Daniel and his friends fasted to follow God and avoid the idolatrous culture they were in. Jesus recognized fast days and assumed the people would fast as stated in Matthew 6:17-18a: “But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret.” Jesus also observed several periods of intense fasting, including 40 days in the wilderness before he began his three years of public ministry.

Special days of fasting carried over into the early Christian church. By the third century the church had begun to establish Lent as a season for spiritual preparation and renewal prior to celebrating the resurrection on Easter Sunday. Lent included special emphasis on prayer, fasting, and giving. Today the season of Lent is observed by many Christian denominations, including the Orthodox and Roman Catholic churches, as well as such Protestant denominations as Lutherans, Anglicans and Episcopalians, Methodists, and some Presbyterians. Lent is a 46-day period (40 days plus Sundays) beginning on Ash Wednesday and ending on the Saturday before Easter. In 2020, Ash Wednesday was on February 26, and Easter Sunday comes on April 12.

Certain days during Lent (Ash Wednesday and all Fridays) are designated as fasting days, when only one main meal a day is to be eaten. This day is a time for additional prayer, and the money saved by eating only one meal is to be given to the poor. Some church traditions include abstaining from eating meat on fast days and abstaining from some other food such as wine, oil, butter, dairy, or sugar during the entire season of Lent. My childhood practice of giving up candy reflects the practice of abstinence. I also remember that my elementary public school cafeteria often served fish on Fridays, especially during Lent, to reflect the Roman Catholic practice of abstaining from meat on Fridays.

In doing research for this article I reviewed information about John Wesley, the founder of Methodism. Wesley believed that fasting should be an important part of every Christian’s life and he personally fasted on a weekly basis. He encouraged his followers to give their savings from not eating to the poor.

The book The Blue Zones highlights the long-lived population in Ikaria, Greece. The residents of Ikaria are Eastern Orthodox; they practice fasting twice per week in addition to the 40-day Lenten season as part of their religious traditions. Because of this regular fasting, it is estimated that their calorie intake is 20-30% less than the average person elsewhere, and it may be one of the factors accounting for their longevity.

Until a few years ago I had never fasted except when absolutely required for a medical procedure. Then a friend at church was battling brain cancer. His wife asked for people who would be willing to fast and pray for him for 24 hours and I willingly volunteered. After that experience I began a more regular fasting practice.

Fasting for Health

Recent nutrition research has looked at the health benefits of intermittent fasting. Intermittent fasting can be defined as abstaining from food for one or more days, but it also includes fasting for shorter periods of time such as 12 to 16 hours. A relatively simple way to begin intermittent fasting is to stop eating at 7 or 8 pm at night and begin the next meal at 8 am, gradually lengthening the time to noon, with only two meals during the day instead of three. When people fast in this way, they generally eat fewer calories and increase their metabolic weight rates lightly, thus helping weight loss. Fasting helps the body increase insulin sensitivity and helps cellular detoxification. Intermittent fasting may also help cardiovascular health and brain health, prevent cancer, and increase life span.

Intermittent fasting does not have to be done every day to deliver health benefits. Studies have looked at alternative patterns such as fasting one or two days a week for 24 hours, eating normally for five days a week and only consuming 500 to 600 calories on two other non-consecutive days, or fasting for 3 to 5 days in a row several times a year. All of these patterns seem to show health benefits for some people.

The practice of abstinence from certain foods for health reasons has also proven to be beneficial. Abstaining from highly addictive foods such as sugar may help break the addiction. People with food allergies must permanently avoid foods they are allergic to. Many of my nutrition clients have abstained from certain foods for a period of time, such as when doing an elimination diet, to identify food sensitivities. Others have abstained from certain foods permanently when they found they had a gluten sensitivity or blood sugar problems. I have abstained from gluten, soy, corn, and some other foods for about nine years due to allergies and sensitivities, and my health improvements have been dramatic.

Many scientific investigations and studies have shown results that reinforce Biblical principles. Fasting and other forms of abstinence can give both spiritual and physical benefits. I encourage all readers, whether religious or not, to consider adopting a fasting or abstinence practice. For Christians, this current season of Lent is a perfect time to start.

Could Some Hormones Be More Protective Against COVID-19?

Good news for those of you who are currently on hormone replacement therapy especially if you’re a woman — new research suggests that sex steroids may play a role in keeping people from developing severe COVID-19 symptoms. One trend that has emerged is the tendency for males to have a more difficult experience with the disease than females. The ratio of COVID-19 deaths are higher among men than women. For every 100 women who die, 135 men die from the disease. In an article recently published in Trends in Endocrinology & Metabolism, Graziano Pinna from the University of Illinois in Chicago outlines some of the evidence suggesting that female reproductive

Valentine’s Day, celebrated on February 14, is set aside to honor those you love. Traditional expressions of love on Valentine’s Day are cards, flowers, food, and jewelry. One of the foods of love is chocolate. The botanical name for chocolate is Theobroma cacao, which means “food of the gods”. But you don’t have to be a god to love chocolate! The Aztecs thought that chocolate was an aphrodisiac. Research has now shown that the ancient wisdom could be true. A recent study showed the connection between eating sweet foods and romantic feelings. Specifically, chocolate helps to release dopamine and serotonin in the brain, and those are some of our feel-good

Should You Eat Healthier In 2021?

“Little by little, one travels far.” Attributed to J.R.R. Tolkien [editor’s note – although this is frequently attributed to Tolkien, it is actually a translation of a Spanish proverb.] Every January many Americans make New Year’s resolutions. One study last year found that 38% of people made one or more of them. The most popular resolutions are related to improving health by losing weight and exercising more. While I am all in favor of this, there are certain people for whom healthy eating is more critical than others. As data has shown this past year, people who suffer from obesity, heart disease, or diabetes are in much more danger of
