The Daniel Fast: A Doctor’s Guide, Food List and 21 Day Plan
Last reviewed and updated: October 30, 2026
Every January, millions of believers begin the year with the Daniel Fast. It is a 21 day season of prayer paired with a simple, plant-based way of eating. Done well, it can reset your table and your heart at the same time.
In this guide I will walk you through what the Daniel Fast is, where it comes from in Scripture, the rules most churches follow, a clear list of foods to eat and avoid, a sample day of meals, a week-by-week plan, and how to handle the first few days. I will also tell you honestly what the research shows, and who should check with their doctor before starting.
Quick answer
- What it is: a partial fast based on Daniel 1 and Daniel 10. You eat whole plant foods and drink water while you focus on prayer.
- How long: usually 21 days. Some people do a 10 day version.
- Eat: fruits, vegetables, beans and lentils, whole grains, nuts, seeds, and plant oils.
- Avoid: meat, dairy, eggs, added sugar and sweeteners (including honey), leavened bread, processed foods, deep-fried foods, and every drink but water.
What Is the Daniel Fast?
The prophet Daniel was a young man from Judah who was carried to Babylon around 605 BC. He was offered rich food and wine from the king’s table, and he chose a simpler path. Two passages in the Book of Daniel are the foundation for the fast:
“Prove thy servants, I beseech thee, ten days; and let them give us pulse to eat, and water to drink.”
Daniel 1:12 (KJV)
“In those days I Daniel was mourning three full weeks. I ate no pleasant bread, neither came flesh nor wine in my mouth, neither did I anoint myself at all, till three whole weeks were fulfilled.”
Daniel 10:2-3 (KJV)
“Pulse” means foods grown from seed, such as vegetables, beans, and grains. “Pleasant bread” is usually understood as rich or delicacy foods. From these two passages, the modern Daniel Fast was born: whole plant foods, water to drink, and no meat, wine, or rich treats for three weeks.
It is called a fast, but it is really a partial fast. You still eat. What you give up is comfort food, and what you gain is time and attention for God. Churches and ministries differ a little on the details, so if your church publishes its own guidelines, follow those.
How Long Is the Daniel Fast?
The most common Daniel Fast lasts 21 days, matching the “three full weeks” in Daniel 10. Many churches start the first or second week of January. Some people follow the 10 day pattern in Daniel 1, and others repeat the fast at other times of the year. There is no rule that it must start in January. What matters most is a clear purpose and a plan you can keep.
Daniel Fast Rules
Most Daniel Fast guidelines come down to five simple rules:
- Eat only whole plant foods. Fruits, vegetables, legumes, whole grains, nuts, and seeds.
- Drink only water. Plain, filtered, sparkling, or with a slice of lemon or cucumber.
- No animal products. No meat, poultry, fish, eggs, or dairy.
- No added sweeteners or leavened bread. No sugar, honey, maple syrup, or artificial sweeteners, and no bread made with yeast.
- No processed or deep-fried foods. If a label lists chemicals, colorings, preservatives, or flavor enhancers, leave it on the shelf.
There is no limit on how much you eat or when. Still, fasting is a practice of self-control, so eat until satisfied, not stuffed.
Daniel Fast Food List
Here is the list I give patients. Print it or screenshot it before you go to the grocery store.
Foods to eat
- Fruits: fresh or frozen, such as berries, apples, oranges, pears, peaches, cherries, grapes, bananas, pomegranates
- Vegetables: leafy greens, broccoli, cauliflower, carrots, beets, peppers, sweet potatoes, squash, avocados
- Legumes: black beans, chickpeas, lentils, kidney beans, split peas, plain tofu
- Whole grains: brown rice, quinoa, oats, barley, millet, amaranth, whole wheat
- Unleavened bread: whole grain flatbread or tortillas made without yeast or sugar
- Nuts and seeds: almonds, walnuts, cashews, pecans, chia, flax, hemp hearts, natural nut butters
- Healthy oils: extra virgin olive oil, avocado oil, coconut oil
- Herbs and spices: fresh or dried, plus a little salt
- Drinks: water only
Foods to avoid
- Meat and fish: beef, pork, chicken, turkey, seafood
- Eggs and dairy: milk, cheese, yogurt, butter, cream
- Sweeteners: sugar, honey, maple syrup, agave, molasses, artificial sweeteners
- Leavened bread: any bread made with yeast, plus most packaged breads, pastries, and crackers
- Processed foods: anything with artificial flavors, colorings, preservatives, or hydrogenated oils, including many packaged vegan foods
- Deep-fried foods: chips, fries, fried snacks
- Solid fats: butter, lard, shortening, margarine
- Drinks: coffee, tea, soda, energy drinks, alcohol, and juice as a beverage
- Candy and gum: including sugar-free mints and gum
A simple label test: if you recognize every ingredient as a food, an herb, or a healthy oil, it is usually fine. If you see added sugar, preservatives, or flavor enhancers like MSG, skip it. Choose single-ingredient foods whenever you can, and cook at home more often. Steel-cut oats made on your stove beat a flavored instant packet every time.
A note on fruit juice: most guides treat 100% juice as food, not a drink. A splash to sweeten a recipe or a whole-fruit smoothie as a meal is fine. Sipping juice all day is not.
A Sample Day of Daniel Fast Meals
People are often surprised how filling this way of eating is. Beans, grains, and vegetables are rich in fiber, which helps you feel full. Here is one simple day:
- Breakfast: steel-cut oats cooked in water, topped with blueberries, chopped walnuts, ground flax, and cinnamon.
- Lunch: a big salad of greens, chickpeas, cucumber, tomato, red onion, and avocado, dressed with olive oil, lemon juice, and herbs.
- Snack: an apple with a spoonful of natural almond butter, or carrot sticks with homemade hummus.
- Dinner: a black bean and roasted sweet potato bowl over brown rice, with sauteed peppers and onions, fresh salsa, and cilantro.
- All day: water. Aim for pale yellow urine as a simple sign you are drinking enough.

Your 21 Day Daniel Fast Plan, Week by Week
The week before: prepare. Write down why you are fasting. Talk with your doctor if you take medication (see below). Start cutting back on coffee and sugar now. Clear tempting foods from the pantry, shop for staples, and cook a pot of beans and a pot of grains so easy meals are ready on day one.
Week 1 (days 1 to 7): adjust. Expect some cravings, and possibly headaches or tiredness in the first few days, especially if you gave up coffee. Keep meals simple and repeat favorites. Set a daily prayer time, ideally at a time you used to spend eating or scrolling. Many people read through the Book of Daniel this week.
Week 2 (days 8 to 14): settle in. For many people, cravings fade and energy steadies this week. Try two or three new recipes so meals do not get boring. Go deeper in prayer: listen as much as you speak, and keep a short journal of what God is showing you.
Week 3 (days 15 to 21): finish strong. This is when motivation can dip. Remember your purpose and lean on a friend or your church group. Begin thinking about which habits you want to keep.
After the fast: return gently. Add foods back one at a time over several days rather than celebrating with a heavy meal. Notice how you feel. Many people choose to keep more vegetables, beans, and water, and less sugar, long after the 21 days end.

Headaches, Caffeine Withdrawal, and Other Common Hiccups
The first three or four days are usually the hardest. Here is how to make them easier:
- Taper caffeine before you start. During the week before, cut your coffee in half every two or three days. Stopping suddenly is the most common cause of Daniel Fast headaches, and they usually ease within a few days.
- Drink water steadily. Dehydration makes headaches and fatigue worse.
- Do not skip meals. Eat regular meals with beans, nuts, or whole grains so your blood sugar stays steady.
- Add fiber slowly if you are not used to it. Gas and bloating are common at first. Rinse canned beans well, start with smaller portions, and drink more water.
- Sleep and move gently. Extra rest and an easy walk help your body adjust.
If a headache is severe, comes with fever, confusion, or weakness, or does not ease after a few days, stop and call your doctor.
Who Should Talk With a Doctor First
For most healthy adults, the Daniel Fast is a safe, whole-food way of eating. But because it changes your diet quickly, please check with your doctor before you begin if any of these apply:
- Diabetes or prediabetes, especially if you take insulin or other medicines that lower blood sugar. Your blood sugar can drop on this plan, and your doses may need adjusting.
- High blood pressure medication. Blood pressure often falls on a plant-based, low-salt diet, which can leave some people lightheaded.
- Pregnancy or breastfeeding. You need enough protein, calories, iron, and other nutrients for two.
- Blood thinners such as warfarin. A sudden increase in leafy greens changes vitamin K intake, which can affect your dose.
- Kidney disease, since many plant foods are high in potassium.
- Any other prescription medication, a history of an eating disorder, or if you are underweight, frail, or a teenager.
Never stop or change a medication on your own because you are fasting.
What the Research Shows
The Daniel Fast is one of the few religious fasts that has been studied directly. Most of the research comes from Dr. Richard Bloomer’s group at the University of Memphis.
- In the first study, 43 adults followed a 21 day Daniel Fast with about 99% compliance. Total cholesterol fell from about 171 to 139 mg/dL and LDL from about 98 to 76 mg/dL, and blood pressure dropped as well. HDL (“good”) cholesterol also went down, and body weight changes were not statistically significant over 21 days (1).
- A related study found improvements in selected markers of antioxidant status and oxidative stress after the 21 day fast (2).
- Another study tested how the body handled a high-fat meal before and after the fast. Diastolic blood pressure was lower afterward, but the drop in after-meal oxidative stress was not statistically significant (3).
- A follow-up found that both the traditional fast and a modified version that included a small amount of lean animal protein improved the cardio-metabolic profile (4).
- A review of religious fasting traditions, including the Daniel Fast, Ramadan, and Greek Orthodox fasting, summarized their effects on health markers and called for more research (5).
These are small, short studies, and results vary from person to person. The Daniel Fast is not a treatment for any disease. But the evidence suggests that three weeks of whole plant foods may support healthier cholesterol and blood pressure numbers.

The Spiritual Side: Prayer and Purpose
The food is the smallest part of the Daniel Fast. Daniel set aside rich food because he was seeking God. The fast is a way of saying, “Lord, You matter more to me than my comfort.”
Before you begin, write down your purpose in one or two sentences. You might be seeking direction for a decision, praying for a loved one, asking for healing in a relationship, or simply wanting to draw closer to God. Then build your days around it:
- Replace a meal habit with prayer. Use the time you would spend on a coffee run or dessert to pray or read Scripture.
- Read with a plan. Start with the Book of Daniel, then the Psalms or the Gospels.
- Keep it humble. Jesus taught, “But thou, when thou fastest, anoint thine head, and wash thy face; that thou appear not unto men to fast, but unto thy Father which is in secret” (Matthew 6:17-18, KJV).
- Fast with others. Many churches fast together in January. Shared meals, recipes, and prayer requests make it easier to finish.
If self-control around food is part of what you are praying about, you may find encouragement in these Bible verses for weight loss and self-control. And if you are curious how a full water fast differs from a partial fast like this one, read what happens in your body when you fast.
Supplements During the Daniel Fast
Most guides allow supplements without added sugar. Keep taking anything your doctor has prescribed. Vitamin D is worth checking in the winter months, and vitamin B12 matters for anyone who stays plant-based for longer than a few weeks. If you want to keep your fast fully plant-based, read capsule labels, since some use gelatin.
Some readers pair their fast with the Divine Health Detox Starter Pack, a bundle of greens, fiber, and antioxidant nutrients designed to support the body’s natural detoxification during a 21 day reset. It is optional. The fast works with food and prayer alone.
Bottom Line
The Daniel Fast is 21 days of whole plant foods, water, and focused prayer, rooted in Daniel 1 and Daniel 10. Prepare the week before, taper your caffeine, keep meals simple, and talk with your doctor if you have diabetes, are pregnant, or take medication. Most of all, go in with a clear purpose. Many people finish the fast feeling closer to God and with healthier habits they want to keep.
Frequently Asked Questions
How long is the Daniel Fast?
The traditional Daniel Fast lasts 21 days, based on Daniel 10:2-3, where Daniel ate no pleasant bread, meat, or wine for three full weeks. Some people follow a 10 day version based on Daniel 1:12. Many churches begin a 21 day Daniel Fast in January.
Can you drink coffee on the Daniel Fast?
No. Water is the only drink on a traditional Daniel Fast, so coffee, tea, soda, and alcohol are set aside for the 21 days. If you drink coffee daily, taper down the week before you start to reduce caffeine withdrawal headaches.
Can you have honey on the Daniel Fast?
No. Most Daniel Fast guidelines exclude all added sweeteners, including honey, maple syrup, agave, sugar, and artificial sweeteners. Use fruit, such as dates, mashed banana, or a splash of 100% fruit juice, to sweeten recipes.
Can you eat bread on the Daniel Fast?
Only unleavened bread. Bread made with yeast is excluded, along with most packaged breads that contain sugar or preservatives. Whole grain flatbreads or tortillas made with only flour, water, oil, and salt are allowed.
Can you eat meat on the Daniel Fast?
No. Daniel 10:3 says no flesh came into his mouth, so the traditional Daniel Fast excludes meat, poultry, fish, eggs, and dairy. Protein comes from beans, lentils, tofu, whole grains, nuts, and seeds. One study tested a modified version with a small amount of lean animal protein, but that is not the traditional fast.
How much weight do people lose on the Daniel Fast?
Results vary. Some people lose a few pounds because they eat fewer calories and no sugar or processed food, while others see little change. In the first published 21 day study, body weight changes were not statistically significant, but cholesterol and blood pressure improved. Weight loss is not the main purpose of the fast.
