What is the 36-Hour Monk Fast?
The monk fast is a form of intermittent fasting that requires abstaining from food for 36 hours once per week. For example, one might finish dinner on Monday and not eat again until breakfast on Wednesday. The practice, popularized by the online community WeFast, is a modern health and wellness approach rather than a traditional religious observance. Its purpose is to induce ketosis, where the body burns stored fat for energy after exhausting its glycogen reserves, typically occurring after about 24 hours without food. Adherents also believe it promotes autophagy, a process where the body cleans out old, damaged cells.
What to Consume During the Fast
The rules for consumption during the 36-hour period are strict to prevent breaking the fast. The goal is to avoid any caloric intake. The approved list is short and simple:
- Water: Drinking plenty of water is essential to stay hydrated and can help manage hunger pangs. Dehydration is a risk during extended fasting since much of our fluid intake comes from food.
- Plain black coffee: Unsweetened and without cream or milk, black coffee is permissible. It provides a calorie-free energy boost.
- Plain herbal tea: Like coffee, herbal tea with no added sweeteners is allowed. It can be a soothing, calorie-free alternative to water.
- Zero-calorie beverages: Flavored sparkling water without any added sugars or calories is also an option for variety.
Preparing for the Monk Fast and Breaking It Safely
Proper preparation and post-fast re-feeding are crucial for a positive experience and to avoid side effects like nausea or fatigue.
Before the Fast
- Eat a nutrient-dense, protein-rich meal: Consuming a hearty, high-protein meal just before starting the fast can help you feel full longer and manage hunger more effectively.
- Stay hydrated: Ensure you are well-hydrated leading up to the fasting period.
Breaking the Fast
Breaking a 36-hour fast requires careful consideration, as your digestive system needs a gentle restart. Overloading your system can cause discomfort.
Best foods to break a monk fast:
- Bone broth: A light, easy-to-digest liquid that replenishes electrolytes and nutrients.
- Vegetable soup: Soups with soft, cooked vegetables are gentle on the stomach.
- Fermented foods: Plain Greek yogurt or other fermented foods can help re-introduce healthy gut bacteria.
- Smoothies: A simple smoothie with a small amount of fruit and protein is a good option.
- Cooked vegetables: Steamed or boiled vegetables are easier to digest than raw ones.
- Healthy fats: Avocado or a small amount of olive oil can be introduced later in the meal.
After a small, light meal, allow your body some time to digest before resuming normal food intake gradually.
Modern Monk Fast vs. Traditional Monastic Diet
It is important to differentiate the modern 36-hour monk fast from traditional monastic dietary practices, which are governed by specific religious rules and are often less restrictive in some ways.
| Feature | Modern 36-Hour Monk Fast | Traditional Catholic Monastic Diet (e.g., Benedictine) | Traditional Buddhist Monastic Diet | Traditional Greek Orthodox Monastic Diet (e.g., Mount Athos) |
|---|---|---|---|---|
| Fasting Frequency | Weekly 36-hour fast | Seasonal fasts (e.g., Lent), plus weekly fasts on specific days | Fasting from noon until sunrise daily | Fasting for over half the year, stricter on weekdays |
| Food Restrictions | Complete caloric abstinence during fast period | Abstinence from meat, and on stricter days, dairy and eggs | Abstinence from food after noon | Abstinence from meat, fish, dairy, eggs, oil, and wine on fast days |
| Permitted Drinks | Water, black coffee, herbal tea | Water, other liquids (historically wine was sometimes permitted) | Fruit juices and other liquids allowed after noon | Water and other non-caloric drinks |
| Dietary Focus | Inducing ketosis, autophagy, weight loss | Moderation, penance, spiritual growth | Mindfulness, discipline, simple plant-based meals | Plant-based staples like vegetables, whole grains, and legumes |
