Yom Kippur, also known as the Day of Atonement, is the holiest day in Judaism. It typically falls in September or October and lasts for about 25 hours. Similar holidays or observances in other religions share themes of fasting, reflection, and atonement:

During this time, Jewish people fast completely—no food or drink—and refrain from work, bathing, and other physical comforts. The day is spent in deep prayer, self-reflection, and seeking forgiveness from both God and other people. It marks the end of the “Ten Days of Repentance” that begin with Rosh Hashanah, the Jewish New Year. The main focus of Yom Kippur is repentance, forgiveness, and spiritual renewal.

Fasting is a common spiritual practice across nearly all major religions, including Judaism, Christianity, Islam, Buddhism, Hinduism, and Jainism. While the religious reasons often focus on spiritual growth, self-discipline, or atonement, modern science has uncovered medical explanations and benefits behind fasting as well.

In Islam, the month of Ramadan is a time of fasting from dawn to sunset, prayer, and self-discipline. It lasts around 30 days and is one of the Five Pillars of Islam. The last 10 nights of Ramadan are particularly significant, especially Laylat al-Qadr (the Night of Power), believed to be when the Quran was first revealed. Muslims seek forgiveness, make extra prayers, and engage in charity.

Another Islamic observance is Ashura, observed on the 10th of the month of Muharram. For Sunni Muslims, it is a day of optional fasting and reflection. For Shia Muslims, it is a day of mourning to commemorate the martyrdom of Imam Hussein at Karbala. It is marked by grief, remembrance, and spiritual reflection.

In Christianity, the season of Lent is a 40-day period of fasting, prayer, and penance leading up to Easter. It begins with Ash Wednesday, where believers reflect on mortality and repentance. Many Christians give up certain pleasures or perform acts of charity as a form of spiritual preparation. The focus is on acknowledging one’s sins and seeking inner transformation.

In Jainism, the festival of Paryushana is a time of fasting, self-discipline, and forgiveness. It usually lasts 8 to 10 days. Jains reflect on their actions, ask for forgiveness from others, and renew their spiritual commitments. A central practice is the phrase “Micchami Dukkadam”, which means “I ask for forgiveness if I have hurt you knowingly or unknowingly.”

In Buddhism, Uposatha days are observed regularly, often on full moons. These are times for increased spiritual effort. On these days, monks and laypeople may fast, meditate, confess misdeeds, and renew their dedication to Buddhist practices. The purpose is spiritual cleansing and recommitment to the path of enlightenment.

Across all of these traditions, common themes emerge: fasting, reflection, repentance, forgiveness, and a desire for spiritual renewal. These holidays remind people of the importance of examining their actions, repairing relationships, and seeking inner peace.

Fasting affects how the body uses energy. When you fast, your body switches from using glucose (sugar) to using stored fat as its primary source of fuel. This process leads to lower blood sugar and insulin levels. Studies show that intermittent fasting can improve insulin sensitivity, which may reduce the risk of developing type 2 diabetes.

Research support: A 2019 study in the journal Cell Metabolism showed that time-restricted eating improved insulin sensitivity and blood pressure in prediabetic men.

During fasting, a process called autophagy is activated. This is the body’s way of cleaning out damaged cells and regenerating new ones. Autophagy plays a critical role in cellular health and has been linked to increased longevity and reduced risk of diseases such as cancer and Alzheimer’s disease.

Research support: Nobel Prize-winning scientist Yoshinori Ohsumi discovered the mechanisms of autophagy, showing its importance in preventing disease and slowing aging.

A 2016 study in Cell found that intermittent fasting reduced inflammation in mice and improved markers of immune function.

A study published in Circulation (2019) noted that intermittent fasting improved several cardiovascular risk factors in both animals and humans.

Studies show that HGH levels can increase up to 5-fold during fasting periods.

While fasting can offer health benefits, it is not safe for everyone. People with diabetes, eating disorders, or chronic health conditions should consult a doctor before fasting. Pregnant or breastfeeding women and children should generally avoid extended fasting. Prolonged or extreme fasting without proper guidance can lead to nutrient deficiencies, fatigue, or low blood pressure.
