1. Start small.
Don’t go from no fasting to attempting a weeklong. Start with one meal; maybe fast one meal a week for several weeks. Then try two meals, and work your way up to a daylong fast. Perhaps eventually try a two-day juice fast.
A juice fast means abstaining from all food and beverage, except for juice and water. Allowing yourself juice provides nutrients and sugar for the body to keep you operating, while also still feeling the effects from going without solid food. It’s not recommended that you abstain from water during a fast of any length.
2. Plan what you’ll do instead of eating.
Fasting isn’t merely an act of self-deprivation, but a spiritual discipline for seeking more of God’s fullness. Which means we should have a plan for what positive pursuit to undertake in the time it normally takes to eat. We spend a good portion of our day with food in front of us. One significant part of fasting is the time it creates for prayer and meditation on God’s word or some act of love for others.
Before diving headlong into a fast, craft a simple plan. Connect it to your purpose for the fast. Each fast should have a specific spiritual purpose. Identify what that is and design a focus to replace the time you would have spent eating. Without a purpose and plan, it’s not Christian fasting; it’s just going hungry.
3. Consider how it will affect others.
Fasting is no license to be unloving. It would be sad to lack concern and care for others around us because of this expression of heightened focus on God. Love for God and for neighbor go together. Good fasting mingles horizontal concern with the vertical. If anything, others should even feel more loved and cared for when we’re fasting.
So as you plan your fast, consider how it will affect others. If you have regular lunches with colleagues or dinners with family or roommates, assess how your abstaining will affect them, and let them know ahead of time, instead of just being a no-show, or springing it on them in the moment that you will not be eating.
4. Fast from something other than food.
Fasting from food is not necessarily for everyone. Some health conditions keep even the most devout from the traditional course. However, fasting is not limited to abstaining from food. As Martyn Lloyd-Jones said, “Fasting should really be made to include abstinence from anything which is legitimate in and of itself for the sake of some special spiritual purpose.”
If the better part of wisdom for you, in your health condition, is not to go without food, consider fasting from television, computer, social media, or some other regular enjoyment that would bend your heart toward greater enjoyment of Jesus. Paul even talks about married couples fasting from sex “for a limited time, that you may devote yourselves to prayer”(1 Corinthians 7:5).
5. Don’t think of white elephants.
When your empty stomach starts to growl and begins sending your brain every “feed me” signal it can, don’t be content to let your mind dwell on the fact that you haven’t eaten. If you make it through with an iron will that says no to your stomach, but doesn’t turn your mind’s eye elsewhere, it says more about your love for food than your love for God.
Christian fasting turns its attention to Jesus or some great cause of his in the world. Christian fasting seeks to take the pains of hunger and transpose them into the key of some eternal anthem, whether it’s fighting against some sin, or pleading for someone’s salvation, or for the cause of the unborn, or longing for a greater taste of Jesus.
1. Prepare Your Mind
Before you begin, think about why you want to fast. What do you want to achieve? It’s important to have the right mindset before you start or you may lose heart early on. Pray for discipline and a strong will to complete the fast.
2. Drink Water
Drink at least eight 8-ounce glasses of puriﬁed water while you are fasting. This will help you stay energized. Dehydration can cause you to feel tired and hungry.
3. Go Easy
Gentle exercise, such as walking, is good, but don’t overexert yourself. While all this important work is going on inside, you want to give your body the rest it needs. Take more breaks. Avoid exhausting work. Go for walks. Get fresh air and sun. Go to bed early.
4. Be Wise
You may have a physical condition that would make fasting unwise or dangerous. Seek medical advice ﬁrst. Be aware of medications and their effects while you fast.
5. Break Smart
Breaking a fast with a heavy meal like a burger and fries or steak and potatoes, can cause harm to your body and you could end up with stomach cramps and digestive issues.
