Fasting Across Religions: Hindu Vrat, Ramadan, Lent, Paryushana, Buddhist and Sikh Views Compared

Quick answer: Almost every major religion knows fasting, but each gives it a different meaning. In Hinduism a vrat or upavasa is usually a voluntary vow linked to a deity or sacred day. In Islam, sawm in Ramadan is an obligatory dawn-to-sunset fast. Christians keep Lent with practices that differ between Catholic, Orthodox and Protestant churches. Jains treat fasting as a central austerity, especially during Paryushana. Buddhist monastics do not eat after midday, and lay Buddhists may do the same on uposatha days. Sikh teaching, as commonly explained, does not prescribe ritual fasting.

Each tradition is described here as its own followers usually describe it, and each contains real internal variety.

Why religions fast: the common ground

Across traditions, fasting is rarely about food alone. Followers commonly describe it as a way to discipline the body and senses, to turn attention towards God or towards inner freedom, to remember those who go hungry, to seek forgiveness or purification, and to strengthen a community that fasts together. Most also teach that a fast without inner change misses the point.

The genuine differences lie in who must fast, when, how strictly, and what the fast is understood to achieve. A Hindu vrat may be an offering of love to a chosen deity; Ramadan fasting is obedience to a command Muslims understand as given by God in the Quran; Lent is a preparation for Easter; a Jain fast is a way to shed karma; and Buddhist restraint serves mindfulness along the Middle Way.

Hinduism: vrat and upavasa

The Sanskrit word upavasa is traditionally explained as "staying near" (upa, near; vasa, dwelling), that is, staying close to the Divine. A vrat is a vow, which often includes a fast along with puja, prayer, a story (katha) and charity. Hinduism has no single central authority on fasting, so practice varies across Shaiva, Vaishnava, Shakta and Smarta families and from region to region.

• Forms of fast: nirjala (no food or water), phalahar (fruit, milk and permitted foods), ekabhukta (one meal a day), or simply avoiding grains, salt, onion and garlic.
• Ekadashi: the eleventh lunar day, twice a month, widely observed by Vaishnavas, usually by avoiding grains and beans. See the November 2026 vrat and fasting calendar.
• Navratri: many devotees fast for some or all of the nine nights of the Goddess with special vrat foods. Rules are explained in Navratri fasting rules 2026.
• Karwa Chauth: in many North Indian families, married women fast from sunrise until moonrise for their husbands' wellbeing. See Karwa Chauth 2026 moonrise times.
• Weekly vows (such as Mondays for Shiva) and season-long observances like Karthika Masam.

Most Hindu teachers stress that the vow is about devotion and self-control rather than hardship, and many lineages explicitly excuse children, the elderly, the ill and pregnant women, or allow a lighter fast. Those who cannot fast are often encouraged to pray, give charity or observe a devotional routine without fasting.

Islam: sawm in Ramadan

Fasting in Ramadan, the ninth month of the Islamic lunar calendar, is one of the Five Pillars of Islam. Muslims understand it as commanded in the Quran, which, in the second chapter, describes fasting as prescribed for believers as it was for those before them, so that they may become mindful of God. Because the Islamic calendar is lunar, Ramadan moves through the seasons.

• From dawn to sunset, adult Muslims who are able abstain from food, drink (including water), smoking and marital relations.
• Suhoor is the pre-dawn meal; iftar is the meal at sunset that breaks the fast, often begun with dates and water following the example of the Prophet Muhammad as recorded in the Hadith.
• The Quran itself gives exemptions: people who are ill or travelling may postpone and make up the days later. Scholars also commonly exempt children before puberty, and women who are menstruating, pregnant or breastfeeding, with rules for making up days or giving compensation (fidya) where a person cannot fast at all.
• Ramadan is also a month of extra prayer, Quran recitation and charity, ending with Eid al-Fitr.

Sunni and Shia Muslims and the various schools of Islamic law all keep the Ramadan fast, differing on some details; Sufi traditions often stress its inner dimension.

Christianity: Lent and other fasts

Christian fasting draws on the Bible, including Jesus's forty days of fasting in the wilderness and his teaching in the Sermon on the Mount that fasting should be done quietly, for God rather than to be seen by others. Lent is the season of prayer, fasting and almsgiving that prepares for Easter. Practice differs considerably between churches:

• Catholic: Ash Wednesday and Good Friday are days of fasting (commonly, one full meal and two small meals) and abstinence from meat, and Fridays in Lent are days of abstinence from meat. Age limits and local rules are set by the Church and national bishops' conferences, and the sick and others are excused.
• Orthodox: Great Lent is generally stricter in diet, traditionally avoiding meat, dairy, eggs and, on many days, fish, wine and oil, with relaxations on certain days. Orthodox Christians also keep other fasting seasons and many Wednesdays and Fridays through the year.
• Protestant: wide variety. Some churches, such as many Anglican, Lutheran and Methodist congregations, observe Lent, often through a personal discipline like giving something up. Others do not keep Lent and treat fasting as a voluntary spiritual practice, sometimes for a particular prayer intention.

Jainism: Paryushana, upvas and ayambil

In Jainism, fasting is one of the most important forms of tapas (austerity), understood as a way to weaken the karma that binds the soul and to practise detachment. It is closely tied to ahimsa, non-violence. Practice differs between the Svetambara and Digambara traditions and among communities, and monks and nuns guide lay followers on what is suitable.

• Paryushana: the most important annual period of reflection and fasting. Svetambara Jains commonly observe eight days, and Digambara Jains observe the ten-day Das Lakshana Parva. It closes with a day of confession and mutual forgiveness, when Jains ask pardon of everyone with the words "Micchami Dukkadam".
• Upvas: a full fast, commonly from sunrise to the next sunrise, with either no food and only boiled water during daylight, or no water at all. Some devotees keep fasts lasting several days.
• Ayambil: one plain, bland meal a day without rich or tasty ingredients such as ghee, milk, oil, sugar and spices.
• Many Jains also avoid eating after sunset throughout the year, as part of minimising harm to small living beings.

Buddhism: the Middle Way and uposatha

Buddhist tradition recalls that the Buddha practised severe fasting before his awakening and then set it aside as unhelpful, teaching a Middle Way between indulgence and harsh self-denial. Fasting is therefore usually understood as moderation and mindfulness rather than extreme austerity.

• Monastic rule: in the Vinaya (monastic discipline), monks and nuns do not eat solid food after midday until the next dawn. This is kept closely in Theravada communities; East Asian and Tibetan monastic practice varies.
• Uposatha days: on full-moon, new-moon and quarter-moon days, many lay Buddhists, especially in Theravada countries, take eight precepts, which include not eating after midday, and spend time at the monastery.
• Mahayana and Vajrayana: some lay Buddhists keep vegetarian days, and Tibetan Buddhism has specific fasting retreats such as Nyungne, associated with Avalokiteshvara, the bodhisattva of compassion.

See Hinduism vs Buddhism: a complete comparative guide for the wider relationship between the two traditions.

Sikhism: a different emphasis

As commonly explained by Sikh teachers, the Guru Granth Sahib does not prescribe ritual fasting, and several of its hymns, including those of Guru Nanak, question rituals that are performed without inner devotion and truthful living. The Sikh emphasis falls on Naam simran (remembering God), honest work, sharing with others and seva (selfless service), seen most clearly in the free community kitchen, langar. See Hinduism vs Sikhism for more.

A health note

Anyone with diabetes, heart or kidney conditions, a history of eating disorders, or who is pregnant, breastfeeding, elderly or on regular medication should talk to a doctor before fasting, and to their own teacher or clergy about a gentler form of observance.

Interfaith respect at work and school

For NRI families in the USA, UK, Canada, Australia and elsewhere, colleagues and classmates may be keeping Ramadan, Lent or Paryushana while you keep Navratri or Ekadashi. A few habits help everyone:

• Ask, do not assume. Practices vary even within one family.
• Avoid pressing food or drink on someone who is fasting, and offer flexibility on lunch meetings or late events.
• If invited to an iftar, a Lenten meal or a Jain gathering, accept gladly, follow the hosts' customs, and ask beforehand about food you can bring.
• When explaining your own vrat, keep it simple: "I'm keeping a Hindu fast for the Goddess this week, so I'm only eating fruit and milk."

Frequently asked questions

Is Hindu fasting compulsory?

Generally, no. Hinduism has no single rule that every Hindu must fast. Vrats are usually taken up voluntarily, by family custom or as a personal vow, and the rules differ by festival, region, sampradaya and family. Many traditions also excuse children, the elderly, the sick and pregnant women, or allow a lighter form such as fruit and milk.

What is the difference between Ramadan fasting and a Hindu vrat?

Islamic sawm in Ramadan is an obligation, one of the Five Pillars of Islam, for adult Muslims who are able, kept every day of the month from dawn to sunset without food or drink, with stated exemptions. A Hindu vrat is usually voluntary, tied to a particular deity or day, and can range from a complete fast to a single meal or a fruit-only diet.

Do all Christians fast during Lent?

No. Catholic and Orthodox Christians have defined Lenten fasting practices, with the Orthodox Great Lent generally being the stricter in diet. Among Protestants practice varies widely: some churches observe Lent with a personal discipline, while others do not observe it at all and treat fasting as a voluntary spiritual practice.

What is ayambil in Jainism?

Ayambil is a Jain austerity in which a person eats once a day a simple, bland meal, commonly described as boiled grains or pulses without ghee, milk, oil, sugar or spices. It is one of several graded forms of Jain fasting, alongside the full fast (upvas) and longer fasts during Paryushana. Details vary between communities, so families follow their own monks, nuns or elders.

Do Sikhs fast?

As commonly explained, the Guru Granth Sahib does not prescribe ritual fasting, and several hymns question rituals done without inner devotion. Sikh practice instead emphasises remembering God (Naam simran), honest work and selfless service such as langar. Individual Sikhs may of course have their own personal practices.

How can I be considerate of a fasting colleague or classmate?

Ask rather than assume, avoid pressing food or drink on them, be flexible about lunch meetings and team events, and do not make their fast the subject of jokes. A simple "let me know if anything would help" is usually appreciated. The same courtesy is welcome when Hindus keep Navratri or Ekadashi vrats at work.
