The Ultimate 72-Hour Fasting Plan to Eliminate Cravings
Below you will find the reasons and rationale as well as the detailed plan for completing a 72-hour fast.
Making progress toward a craving free life is both wildly simple, yet requires confronting all the ways we have added unneeded complexity to our lives. You're likely juggling career ambitions, social commitments, and personal growth outlets. You may see that notification on your phone reminding you that you spend 7-10 hours a day on that screen alone. Finding ways to optimize your health, sharpen your focus, and reset your body can feel like an uphill battle. Enter the 72-hour fast—a powerful yet simple tool to transform your physical and mental well-being, draw out the stuff laying dormant underneath your cravings, and reset your body and brain.
Fasting for three days might sound like a daunting task at first, but when done correctly, it offers a wealth of benefits backed by science. Whether you’re looking to shed extra weight, boost your focus, or detoxify your body, a 72-hour fast can deliver transformative results. Let’s break it down so you can understand the benefits, prepare properly, and achieve success.
Why Should You Consider a 72-Hour Fast?
At first glance, the idea of going three days without food may seem extreme, even counterintuitive. Isn’t eating consistently the key to staying healthy and energized? Surprisingly, modern science shows that periodic extended fasting, when done safely, can be one of the most effective strategies to optimize both your body and mind. Facilities like TrueNorth Health Center, Buchinger Wilhelmi, and Cleanse Center even offer supervised extended fasts surpassing 30 days!
Research has demonstrated that fasting periods of 24, 48, or even 72 hours can promote significant health improvements, especially for individuals in good overall health. A fast like this allows your body to shift its energy usage, clear out toxins, and focus on repair and renewal.
While fasting isn’t for everyone (and we’ll cover who should avoid it), it’s something most healthy adults can safely incorporate into their lives with a little preparation and the right mindset.
What Makes a 72-Hour Fast So Effective?
Here are some of the remarkable benefits you can unlock with an extended fast:
1. Weight Loss and Metabolic Boost
The most obvious benefit of fasting is weight loss. When you stop eating for three days, your body uses up its stored glycogen (carbohydrates) and begins burning fat for energy. This metabolic switch can help you shed stubborn pounds while improving your insulin sensitivity. For many, this means better blood sugar regulation and a reduced risk of developing conditions like type 2 diabetes.
2. Cellular Cleanup Through Autophagy
During a 72-hour fast, your body enters a state called autophagy (we wrote a whole article on this you can read here). This is a natural process where your cells identify and eliminate damaged components, clearing out "cellular garbage" that can accumulate over time. Think of it as a deep cleaning for your body at the cellular level, which can improve overall health and reduce the risk of diseases like cancer and neurodegenerative conditions.
3. Heightened Mental Clarity
Fasting doesn’t just benefit your body—it’s a boost for your brain as well. Many people report improved focus, sharper thinking, and a greater sense of mental clarity during extended fasts. This cognitive upgrade is partly due to the body’s shift to using ketones for energy, which provides a steady and efficient fuel source for the brain.
4. Reduced Inflammation and Stronger Immunity
By giving your digestive system a rest, fasting allows your body to focus on reducing inflammation and repairing itself. It’s like hitting a reset button on your immune system, which is why fasting has been linked to improvements in immune function and a reduced risk of chronic inflammatory conditions.
5. Long-Term Health Benefits
Fasting has been shown to stimulate natural stem cell production, activate repair pathways, and even promote new neuron growth in the brain. These processes can contribute to a longer, healthier life, with a reduced risk of conditions like dementia, heart disease, and cancer.
Who Should (and Shouldn’t) Attempt a 72-Hour Fast?
A 72-hour fast is an excellent option for:
Healthy individuals who want to detoxify their bodies, lose weight, or challenge themselves mentally.
Athletes looking to improve metabolic flexibility.
Busy professionals who want to boost focus and productivity.
Who Should Avoid It:
Those with medical conditions like diabetes or eating disorders.
Pregnant or breastfeeding women.
Individuals taking medications that must be consumed with food.
Always consult a healthcare professional if you’re unsure whether fasting is right for you.
Step-by-Step Guide to Completing a 72-Hour Fast
A successful fast requires more than just willpower. Proper planning and preparation can make the experience smoother and more beneficial. We will go into more detail on each of these in the detailed plan section below.
1. Prepare Your Body
Start small. If you’ve never fasted before, begin with a 24-hour fast to help your body adjust. Gradually work up to a 48-hour and eventually a 72-hour fast.
Choose a time when your schedule is light—like a weekend or a quiet work period—to reduce stress and distractions. Before you start, enjoy a balanced meal with lean protein, vegetables, and healthy fats. Avoid overeating; the goal is to feel satisfied, not stuffed.
2. Stay Hydrated
Water is your best friend during a fast. Aim to drink at least 3 liters of water daily to stay hydrated. Adding a pinch of Himalayan salt to your water can help maintain electrolyte balance, especially if you’re new to fasting. Herbal teas are also a great option, and a small amount of coffee is fine if you need an energy boost.
3. Manage Expectations
The first day of fasting might feel challenging as your body adjusts to the lack of food. Hunger, fatigue, or mood swings are common. By day two, your body will begin burning fat for fuel, which often leads to a surge in energy and focus.
4. Stay Active (But Don’t Overdo It)
Light exercise like walking, a light run, moderate lifting session, or stretching can help you feel more energized during your fast. Avoid intense workouts or high-impact activities, as your body needs extra rest during this period.
5. Break the Fast Properly
After 72 hours, your digestive system will need time to wake back up. Start with something light, like bone broth, fresh fruit, or yogurt. Gradually transition to a balanced meal with protein and vegetables to avoid overwhelming your stomach.
How to Maintain the Benefits
Fasting isn’t just a one-time fix—it can become a valuable part of your health routine. Depending on your goals, you might incorporate a 72-hour fast a few times a year. For ongoing benefits, pair fasting with healthy eating habits, regular exercise, and stress management techniques.
Support and Accountability
Fasting for three days is a challenge, but you don’t have to go it alone. Partnering with friends, family, or a coach can make all the difference. Share your goals, celebrate milestones, and stay motivated together.

Detailed Plan for Completing a 72-Hour Fast
A 72-hour water fast is an incredible way to reset your body and mind, activate autophagy, and take control of cravings. This plan includes detailed strategies, workout suggestions, and tips to help you succeed.
Preparation Phase (1-3 Days Before the Fast)
Proper preparation can make or break your fasting experience.
1. Adjust Your Diet (do this at least 7 days ahead of your fast start date)
Gradually reduce meal sizes: Start eating slightly smaller meals leading up to your fast to ease your body into lower calorie intake.
Focus on whole foods: Eat lean proteins, vegetables, healthy fats (avocados, nuts, olive oil), and whole grains.
Cut back on sugar and processed carbs: This reduces glycogen dependence, making the transition to fasting easier.
Hydrate well: Begin increasing your water intake to ensure you start the fast hydrated.
2. Plan Your Schedule
Choose a time when you can rest and avoid high-stress situations. Weekends or light workdays are ideal.
Pick a start time (e.g. Sunday at 6pm) and an end time (e.g. Wednesday at 6pm) so there isn’t any ambiguity.
It’s ideal to have a few people come with you on this journey, either to coach you through it or to be in it with you along the way. We regularly take up fasts with groups of men who want the support and to do it together. You can find those groups and hear about upcoming fasts by visiting: thefreedomgroup.co/jointhefast.
3. Prepare Mentally
Journal your goals for the fast—this will help keep you motivated.
Set your intentions: Focus on the benefits like eliminating cravings, improving discipline, and resetting your body.
4. Light Exercise Before Starting
Perform light to moderate cardio or strength training the day before fasting. This helps deplete glycogen stores so your body transitions to fat-burning more quickly.
During the Fast: Day-by-Day Breakdown
Day 1: Transition to Fasting
Your body will burn glycogen (stored carbs) for energy. Cravings and hunger will be strongest on this day.
Hydration is key: Drink at least 3 liters of water. Add a pinch of Himalayan salt or electrolytes to maintain balance.
Drink herbal teas or black coffee: These can suppress appetite and provide mental clarity.
Mindset strategy: Focus on your “why.” Remind yourself of the benefits—this is when mental discipline begins.
Light activity: Go for a short walk or practice yoga to distract yourself from hunger. Avoid intense exercise.
Relaxation techniques: Use meditation or deep breathing to reduce stress and hunger signals.
Day 2: Fat-Burning Mode
Your body starts producing ketones from fat stores. Hunger subsides, but you may feel low energy as your body transitions.
Hydration: Continue drinking at least 3 liters of water. Mineral water can help replenish electrolytes.
Light activity:
Morning: A short 10-15 minute yoga session or stretching routine.
Afternoon: A leisurely 20-30 minute walk outside for fresh air and mental clarity.
Mindset strategy: Journal about cravings that arise and how you respond. Reflect on how cravings are signals, not commands.
Self-care: Take a warm bath, read a book, or listen to calming music to relax and occupy your mind.
Day 3: Autophagy Peak
Autophagy is in full swing, and cravings typically decrease. Energy levels often stabilize, and mental clarity improves.
Hydration: Same as the previous days—keep water intake consistent.
Light activity:
Morning: A gentle stretching or breathing session to start the day.
Midday: A short, light walk (15-20 minutes) to boost circulation.
Mindset strategy: Reflect on your progress. Use affirmations like, “I am stronger than my cravings,” or “This process is healing my body and mind.”
Visualization: Picture how this fast is helping you reset—your cells repairing themselves, your cravings losing power, and your mind gaining clarity.
Rest: Allow yourself to nap if you feel fatigued. Sleep is vital for recovery.
Breaking the Fast
The way you end your fast is as important as how you begin it. Reintroduce food gradually to avoid overwhelming your digestive system.
Step 1: First Meal (Light and Easy to Digest)
Timing: Break your fast in the evening on Day 3.
What to eat:
Bone broth or vegetable broth (small bowl).
A piece of fresh fruit like watermelon or an orange.
Yogurt or a small portion of avocado.
Portion control: Start small and eat slowly. Listen to your body.
Step 2: Second Meal (Balanced and Nourishing)
About an hour after your first meal, eat a well-balanced meal with:
Lean protein (chicken, fish, or tofu).
Steamed or roasted vegetables (zucchini, spinach, carrots).
Healthy fats (avocado, olive oil).
Step 3: Return to Normal Eating
The next day, resume your regular meals, focusing on whole foods and avoiding processed options.
Additional Strategies for Success
Support System:
Have a fasting buddy or accountability partner to encourage you during challenging moments.
Use online communities or apps to track your progress and stay motivated.
Mindfulness Tools:
Practice meditation to connect with your body and reduce the mental chatter around food.
Journal about your experience to identify patterns or triggers in your cravings.
Plan Distractions:
Keep yourself busy with light, enjoyable activities like reading, organizing, or taking nature walks.
Avoid environments that trigger cravings, like your favorite restaurant or the snack aisle.
Workout Suggestions for the Fast
Stick to light, low-intensity activities to conserve energy while supporting circulation and mental clarity.
Day 1: Light workout, a run, or a short walk (15-30 minutes).
Day 2: Leisurely walks (20-30 minutes) and light bodyweight exercises like squats or pushups (just a few sets).
Day 3: Gentle stretches, breathing exercises, or a relaxing walk.
Avoid intense cardio, heavy lifting, or high-intensity interval training (HIIT) during the fast to prevent energy crashes.
Post-Fast Recovery Tips
Continue hydrating to support your digestive system as it readjusts.
Stick to nutrient-dense meals for the following few days to maximize the benefits of autophagy and fat-burning.
Reflect on the experience—what worked, what didn’t, and how it helped with cravings.
Final Thoughts
A 72-hour water fast is more than a physical challenge—it’s a mental and emotional reset. By tapping into autophagy, you’re giving your body the tools to heal, rejuvenate, and eliminate cravings at their root.
