If you attend any church, anywhere, there’s a very good chance you’ve heard of the 21 day Daniel Fast!
The problem is that while most people agree on the main details – eating just fruits and vegetables for 21 days – things can get murky after that. I’ve heard questions like:
- What exactly can I eat and drink?
- Can I have coffee or tea?
- Are natural sweeteners like honey or stevia allowed?
- Does the fast have to be 21 days?
- Is it okay to eat ‘Daniel-friendly’ versions of junk food?
My intention with today’s post is to save you some googling by putting all of the info you need, all in one place. So let’s chat, shall we?
Understanding the 21 Day Daniel Fast
The Daniel Fast is a 21-day spiritual discipline that combines restricted eating with focused prayer and Bible study. This biblical practice involves eating only plant-based foods while avoiding meat, dairy, processed foods, and sweeteners.
Biblical Origins and Significance
The Daniel Fast comes from the Old Testament book of Daniel. In chapter one, Daniel and his friends were taken as exiles to Babylon, where they refused the king’s food and wine.
The king’s food likely included items that went against Jewish dietary laws. These young men wanted to stay faithful to God even in a foreign land and so, asked to eat only vegetables and drink only water for ten days instead.
In Daniel chapter ten, the prophet fasted again for three weeks.
During this time, he ate no rich food, meat, or wine. This 21-day period of fasting and prayer led to a powerful spiritual experience and even an angelic visitation!
Purpose of the Daniel Fast
The purpose of completing a Daniel Fast today is to draw closer to God through prayer and spiritual discipline. The fast helps you focus on your relationship with the Holy Spirit by removing the distraction and influence of food from your life.
Many people use this practice to seek clarity and understanding when facing an important, potenitally life-changing decision. The 21 days of prayer, combined with restricted eating, can help to create space for God to speak into your life.
Others use this fast to help break unhealthy eating habits and food addictions. Removing processed foods and sugar can reset your body while strengthening your faith.
21-Day Commitment and Key Principles
The 21-day Daniel Fast follows specific dietary guidelines. You eat only fruits, vegetables, whole grains, legumes, nuts, and seeds, and drink only water.
Foods to avoid include all animal products, sweeteners, leavened bread, caffeine, and alcohol. Processed and fried foods are also off-limits during the fast.
These restrictions, combined with the length of the fast, are going to require planning and preparation. After all, these aren’t standards you can easily meet in a fast food drive-through if you’re too tired to cook one night.
It’s important to remember that the 21 day Daniel Fast is about much more than what you eat! The commitment should extend beyond food choices to include equally-intentional prayer and Bible reading.

Planning and Practicing the Daniel Fast
A successful fast will require thoughtful preparation of both your meals and your spiritual disciplines. You’ll need to plan what foods to eat, schedule time for prayer and Bible study, and prepare for both physical and mental challenges.
Creating a Fasting Plan
Before your fast starts, take time to prepare your body and mind.
Consider gradually reducing the caffeine, sugar, and processed foods in your diet a few days before beginning. This will help to ease your transition into your new diet.
Set specific goals for your 21-day journey.
Write down your prayer request items and what you hope to gain spiritually. You might want to seek break-through in a specific area, grow closer to God, or develop better self-discipline.
Plan your daily schedule to include a dedicated time of prayer.
Many people find success scheduling their morning prayer sessions before eating breakfast. Others plan their time of prayer during lunch or evening hours. The key is going to be consistency and intentionality.
You might also consider reducing social media and entertainment during your fast. This can create more time and space for spiritual growth, plus help you avoid temptations related to food advertisements or posts.
Appropriate Foods and Ingredients
The Daniel Fast eating plan focuses on simple food choices that are plant-based and unprocessed.
You can eat all fruits and vegetables, whether fresh, frozen, or canned without additives. Whole grains like brown rice, quinoa, oats, and whole wheat are other staples that will help you feel full.
Approved Foods:
- All vegetables and fruits
- Whole grains (brown rice, oats, quinoa, barley)
- Legumes and beans
- Nuts and seeds
- Quality plant-based oils (olive, coconut, avocado)
- Herbal tea and water
Foods to Avoid:
- All animal products (meat, dairy, eggs)
- Sweeteners and added sugars
- Leavened bread and baked goods
- Deep-fried foods, processed foods, and fast food
- Caffeine and carbonated beverages
- Choice food items like desserts and chips
You’ll need to avoid all animal products, including fish, chicken, beef, and dairy. Soy products like tofu and tempeh are generally acceptable.
Nut butters such as almond butter or peanut butter can make great protein sources, but be sure to check labels to find those without added sugars or oils.
Many packaged foods contain hidden additives or preservatives that won’t align with your fast. You’ll want to stick to whole, unprocessed ingredients whenever possible.
Spiritual Practices During Daniel’s Fast
When following the 21 day Daniel Fast, your physical fasting should always be partnered with intentionally seeking God’s presence.
Prioritize reading the Bible during this time to connect directly to God’s Word…the easiest and most trustworthy way to hear God’s voice!
Set aside specific times each day to read Scripture, pray, and reflect. Many people follow a 21-day devotional plan for easy reference to daily readings and devotions.
Start each morning with prayer, asking God to speak to you throughout the day. You should also spend time listening in prayer, not just talking.
Quiet your mind and create space to hear from the Holy Spirit. This practice of listening prayer during fasting can transform how you experience God. (Click here for help differentiating between God’s voice and your own thoughts.)
Journaling your thoughts, prayers, and insights can create a helpful record of your spiritual journey. Write down what God reveals to you and any answers to prayer you receive.
Maintaining Health and Overcoming Challenges
Even though you’re fasting for spiritual purposes, fasting is obviously a very physical act as well. That’s why it’s important to care for your physical body during a 21 day Daniel Fast.
Drink plenty of water throughout each day. Aim for eight glasses or more to stay hydrated and help your body adjust.
You might experience headaches, fatigue, or irritability during the first few days.
These symptoms usually come from caffeine withdrawal or blood sugar changes. Taking healthy doses of rest and staying hydrated will help your body adjust.
If you have health concerns like diabetes, pregnancy, or other medical conditions, consult your doctor before starting. The Daniel Fast can be modified to address specific needs while maintaining its spiritual focus.

What about all those questions?
Just in case you missed the answers, let’s address the initial questions above as directly as possible, shall we?
What exactly can I eat and drink?
This is the most frequent question. The general rule of thumb is “if it comes from a seed, you can eat it.”
- Allowed: All fruits, all vegetables, all whole grains (brown rice, oats, quinoa), all legumes (beans, lentils), all nuts and seeds, and high-quality oils (olive, avocado).
- Prohibited: Meat, dairy, eggs, sugar/sweeteners of any kind, leavened bread (anything with yeast), processed foods, and deep-fried foods.
- Drink: The only beverage strictly allowed is water.
Can I have coffee or tea?
This is often the hardest part for people. (I’m raising my hand right along with you!)
Technically, the answer is no. Since the fast is based on Daniel’s choice to drink only water (Daniel 1:12), coffee and tea are excluded.
Additionally, the fast aims to “deny the flesh,” and for many, caffeine is a daily crutch or a “pleasant” stimulant that the fast seeks to temporarily remove. Some people choose to drink herbal tea, but strictly speaking, water is the standard.
Are natural sweeteners like honey, stevia, or maple syrup allowed?
Ugh, I hate being a bummer, but…no. Even though honey and maple syrup are “natural,” they’re still sweeteners.
The Daniel Fast excludes all “pleasant foods” and “choice foods.” The goal is to eliminate the craving for sweets and to focus on sustenance rather than indulgence.
Why is the fast 21 days long?
The duration comes from Daniel 10:2-3, which says: “At that time I, Daniel, mourned for three weeks. I ate no choice food; no meat or wine touched my lips…”
The 21-day period is seen as a significant enough amount of time to break old habits, detoxify the body, and dedicate a concentrated season to prayer and seeking God.
Is it okay to eat “Daniel-friendly” versions of junk food?
This is a common “grey area” question. For example, is it okay to make homemade potato chips fried in olive oil, or a “Daniel-fast pizza” with whole-wheat flatbread and no cheese?
Most spiritual leaders suggest that while the ingredients might be “legal,” the spirit of the fast is about simplicity and sacrifice. If you’re spending all your time trying to “cheat” the system by making healthier versions of junk food, you may be missing the spiritual focus of the fast.
