LDS Fast Sunday and Fasting: Spiritual Discipline and Service

The first Sunday of each month is Fast Sunday in The Church of Jesus Christ of Latter-day Saints. Members abstain from food and water for two consecutive meals (approximately 24 hours) and donate money they would have spent on food — and ideally more — as a "fast offering" to help the poor and needy. Fasting is a spiritual practice with deep scriptural roots, designed to draw people closer to God, develop self-discipline, create empathy for the hungry, and provide powerful spiritual experiences through petition and testimony.

The practice of fasting appears throughout scripture. In the Old Testament, fasting was a sign of grief, repentance, or preparation for receiving divine guidance (Esther 4:16, Daniel 9:3). In the New Testament, Jesus fasted in the wilderness before His ministry (Matthew 4:2) and taught about fasting (Matthew 6:16-18). In the Restoration, the Lord revealed modern guidance on fasting in the Doctrine and Covenants, establishing Fast Sunday as a monthly practice for all Church members capable of fasting.

What Is Fast Sunday?

Fast Sunday is observed on the first Sunday of each month. The practice is straightforward: members abstain from eating and drinking (including water) for two consecutive meals. Traditionally, this means skipping breakfast and lunch on Sunday and eating a regular dinner after sacrament meeting. The timing makes it convenient for families to fast together and ensures that members go to sacrament meeting hungry, with their minds focused on spiritual matters rather than temporal comfort.

The fast lasts approximately 24 hours, though some members fast for longer periods (a full 24-hour day, or even multiple days) for special spiritual purposes. However, the standard practice, appropriate for children and those without health issues, is the two-meal fast.

Fasting is not mandatory for all members. The Church explicitly exempts children (under the age of eight), pregnant and nursing women, those with medical conditions that make fasting inadvisable (diabetes, eating disorders, etc.), and those whose doctors advise against it. Members are encouraged to listen to their bodies and their doctors. The spiritual purpose of fasting is growth, not harm.

How LDS Fasting Works

On Fast Sunday morning, members wake early, skip breakfast, and come to sacrament meeting. Arriving hungry is intentional — it is meant to remind members of their dependence on God and create a state of mind receptive to spiritual experience. During the sacrament meeting, members partake of the sacrament (bread and water), which for many marks the beginning of their fast, though the sacrament itself is not considered "breaking" the fast.

After sacrament meeting, members continue their fast, skipping lunch. Some members drink water if they become thirsty, as the exact rules about water can vary. The fast ends with dinner — a regular meal shared with family or friends. For many families, dinner after Fast Sunday is a special meal where members come together to discuss their fasting experience and what they learned.

The spiritual dimension of fasting involves prayer and petition. As members fast, they often pray about specific challenges, seek healing, pray for distant loved ones, or deepen their connection with God. Some members have profound spiritual experiences while fasting — receiving answers to prayers, gaining clarity about decisions, or feeling a deep sense of peace and God's presence.

Fast Offerings: Fasting to Feed Others

The financial aspect of fasting is equally important. Members are asked to contribute as a "fast offering" the money they would have spent on the meals they skipped — typically $10-$20 depending on family size and meal costs. However, the Church encourages members to give more if they are able, understanding that the spiritual purpose of fasting is enhanced by sacrificial giving.

These fast offerings are collected by the bishop (or ward financial clerk) and administered to help members in need within the local ward. If a member is facing temporary hardship — job loss, medical emergency, or family crisis — the bishop can use fast offering funds to provide groceries, utility assistance, or rental help. Fast offerings can also be used for humanitarian aid, helping members in other parts of the world who face disasters or severe poverty.

This model reflects a core LDS value: that fasting is not merely a personal spiritual practice but a community act of caring. As members fast, they literally give up food to feed others. This creates a powerful cycle of sacrifice and service: by denying their own hunger, members develop empathy for those who are chronically hungry and contribute to caring for them.

Fast Sunday Testimony Meeting

On Fast Sunday, the sacrament meeting structure changes. After the sacrament is administered, instead of scheduled speakers, the meeting opens for open-mic testimony. This is called "Fast and Testimony Meeting." Members stand and share, in their own words, their personal testimony of Jesus Christ, the gospel, the Church, or specific spiritual experiences. These testimonies are brief (usually 2-3 minutes) and deeply personal.

In a testimony meeting, you might hear a teenager share how they prayed for help with a school test and found the answers. A widow might testify of her confidence that she will see her deceased husband again. A recent convert might share the powerful experience of joining the Church. A young child, helped by a parent, might say, "I know Jesus loves me." An older member might reflect on seventy years of faithful service and God's constant presence.

Testimony meetings are often the most moving and authentic moments of the Church month. They reveal the depth of faith and personal spiritual experience of ordinary members. They also create an atmosphere of vulnerability and openness that strengthens community bonds.

Who Is Exempt from Fasting

The Church explicitly teaches that certain members should not fast. Children under the age of eight are exempt because they are too young to understand the purpose and because their growing bodies need consistent nutrition. Pregnant women should not fast due to the demands of pregnancy on their bodies. Nursing mothers should not fast because it affects milk supply and nutrition for the baby.

Members with medical conditions — diabetes, eating disorders, hypoglycemia, or other conditions where fasting poses a health risk — should not fast. Members should follow their doctor's advice about fasting. The Church leadership has taught that it is more important to care for your health than to keep a strict fasting schedule.

Elderly members, those who are ill or recovering from surgery, and others whose health is compromised should feel free to skip fasting. Members with mental health conditions that might be exacerbated by fasting should consult with their doctors and leaders. The spiritual purpose of fasting is to draw closer to God, and if fasting harms your health, it defeats that purpose.

The Spiritual Purpose of Fasting

Beyond the specific practices, fasting in the LDS tradition serves deep spiritual purposes. Fasting teaches discipline and self-mastery — the ability to deny a basic physical need in service of a spiritual goal. It creates a powerful state of focused prayer and openness to God's guidance. It develops compassion and empathy for those who are hungry and poor. And it affirms the core value that spiritual things matter more than material comfort.

The scriptural basis for LDS fasting is found in Isaiah 58, where the prophet describes the kind of fast God desires: one that includes not just abstaining from food, but loosing the bonds of wickedness, letting the oppressed go free, breaking every yoke, sharing bread with the hungry, bringing the homeless poor into the house, and clothing the naked (Isaiah 58:6-7). In this vision, fasting is not merely personal discipline but social action and justice.
