4 min read

According to ProLon, the day after a 5-day fasting-mimicking program should involve a transition diet lasting at least 12 hours, starting with light, liquid foods to re-engage the digestive system gradually. Knowing what to eat after ProLon 5 day fast is critical for sustaining the benefits and preventing discomfort as your body adjusts.

Quick Summary

This guide details the crucial refeeding phase following a ProLon 5-day fast, outlining the optimal progression from light, liquid-based foods on Day 6 to a regular, healthy diet by Day 7. It offers specific food recommendations, explains what to avoid to prevent digestive issues, and provides tips for successful long-term nutritional habits.

Key Points

  • Gentle Refeeding: Ease back into eating with light, liquid-based foods on Day 6 to prevent digestive upset.

  • Start Small: Begin with small, manageable portions to allow your digestive system to reactivate slowly.

  • Prioritize Liquids: Incorporate hydrating foods like vegetable broths, pureed soups, and simple smoothies during the first 12-24 hours.

  • Reintroduce Solids Gradually: After the initial transition period, add soft, cooked vegetables and lean protein before moving to heavier, more complex foods.

  • Avoid Harsh Foods: Steer clear of high-sugar, high-fat, highly processed, and high-fiber raw foods immediately after the fast.

  • Hydrate Consistently: Continue drinking plenty of water and herbal teas to support your body post-fast.

  • Plan for Long-Term Health: Use the refeeding phase as a reset, aiming for a nutrient-dense, whole-food-based diet like the Mediterranean diet.

The Importance of the Refeeding Phase After ProLon

After completing the ProLon 5-day fasting-mimicking program, your body has been in a state of fasting, cellular clean-up (autophagy), and regeneration. This process is delicate, and breaking the fast abruptly with heavy, rich, or processed foods can cause digestive distress, overwhelm your system, and negate the benefits you’ve worked hard to achieve. The refeeding, or transition, phase is the final and crucial step in the process, ensuring a smooth and healthy return to your normal eating patterns.

Transition Day (Day 6): Easing Your Body Back to Digestion

For the first 12 to 24 hours after your fast, it is essential to reintroduce food gently. This allows your digestive enzymes and gut bacteria to reactivate without being overwhelmed. Start with small, light meals and liquids to slowly warm up your system. The ProLon team and other experts recommend a specific hierarchy of foods during this critical time.

Start with Liquids:

  • Vegetable Soups and Broths: These are hydrating and packed with nutrients while being very easy to digest. Opt for clear, low-sodium broths or pureed vegetable soups.
  • Fruit and Vegetable Juices (Fresh): Small amounts of fresh, preferably centrifuged, juices can provide a gentle boost of natural sugars and vitamins.
  • Water and Herbal Tea: Continue to hydrate consistently throughout the day. Herbal teas can also be soothing for the digestive tract.

Move to Soft, Light Solids:

  • Smoothies: A simple, low-fiber smoothie made with banana, berries, and unsweetened plant-based milk or coconut water is an excellent option for Day 6.
  • Cooked Vegetables: Lightly steamed vegetables like zucchini, summer squash, carrots, and sweet potatoes are easy to digest and nutrient-dense.
  • Avocado: This is a great source of healthy fats and potassium, which can help replenish electrolytes. Mash it on a small piece of whole-wheat toast.

Beyond the Transition: Resuming a Healthy Diet

On Day 7 and onwards, you can begin to gradually reincorporate a wider variety of foods and larger portions. The goal is to build on the foundation of clean eating established during the fast. A healthy diet, such as the Mediterranean diet, is often recommended for maintaining the benefits of the ProLon program.

Best practices for a successful transition:

  • Prioritize Whole Foods: Focus on nutrient-dense, unprocessed foods. This includes a wide array of vegetables, fruits, legumes, whole grains, nuts, and seeds.
  • Introduce Protein Gradually: Start with small portions of lean protein. Plant-based proteins like lentils, chickpeas, or tofu are excellent choices. Low-mercury fish is another good option. Heavier animal proteins like red meat should be added back slowly.
  • Listen to Your Body: Pay attention to how different foods make you feel. If a food causes discomfort, reduce the portion or wait another day before trying it again.

Foods to Include vs. Foods to Avoid

Making informed choices during the refeeding process is crucial for a positive experience and long-term health. Below is a comparison of what to prioritize and what to steer clear of.

Foods to Include Foods to Avoid
Warm Broth (Vegetable, Bone) High-Sugar Foods (Candy, Pastries, Sugary Drinks)
Pureed Vegetable Soups Refined Grains (White bread, pasta, rice)
Cooked, Steamed Vegetables High-Fat Foods (Fried foods, heavy meals)
Simple Smoothies (Low-fiber) Heavy Dairy (Cheese, cream)
Healthy Fats (Avocado, small nuts/seeds) Processed Foods (Snacks, ready meals)
Low-Sugar Fruits (Berries, Watermelon) High-Fiber Raw Veggies (Broccoli, Cauliflower)
Lean Proteins (Fish, Tofu, Legumes) Alcohol
Fermented Foods (Yogurt, Kefir) Large Meals

The Importance of Hydration and Electrolytes

During your fast, and especially during refeeding, staying properly hydrated is vital. Dehydration can exacerbate symptoms like headaches and fatigue. While on the ProLon program, your fluid intake includes the L-Drink and herbal teas. Post-fast, continue to drink plenty of water. Electrolytes are also important for cellular function, and foods like avocados and bone broth can help replenish them naturally.

Conclusion

Completing a ProLon 5-day fast is a significant step towards a healthier lifestyle. The actions you take in the immediate aftermath are just as important as the fast itself. By mindfully reintroducing light, nutrient-dense, and easy-to-digest foods on Day 6, you support your body’s recovery and solidify the benefits of the fast. This gentle transition prevents digestive issues and prepares your system for a sustainable, healthy eating pattern. A slow, thoughtful approach to refeeding ensures you reap the full rewards of your fasting journey, setting the stage for long-term well-being.

Frequently Asked Questions

The very first food you should eat after your ProLon fast is a light, liquid food. This could be a warm vegetable broth, a simple, low-sugar smoothie, or a pureed vegetable soup. This eases your digestive system back into action gently.

After the fast, you can resume drinking black coffee or tea, but it's recommended to avoid adding any sugar, milk, or artificial sweeteners. This helps maintain the metabolic reset and avoids an insulin spike.

The transition period lasts for at least 12 hours on Day 6, where you follow a specific transition diet of light foods. You can then gradually resume a normal, healthy diet on Day 7, depending on how your body feels.

High-fiber foods, especially raw vegetables, can be difficult for your digestive system to process right after a fast. Introducing them too quickly can cause discomfort, bloating, and gas. Cooked vegetables are a gentler option.

It is not recommended to eat heavy proteins like red meat or large portions of fish on Day 6. Instead, introduce small portions of light protein like fish or legumes on Day 6 and heavier animal proteins much later.

No, you should avoid alcohol entirely during the refeeding phase. Alcohol is an inflammatory substance that can disrupt the benefits of your fast and irritate your digestive system.

If you feel lightheaded, it is important to address it immediately. Try drinking some juice or a beverage with sugar, and if symptoms persist, it is best to contact your physician.

To avoid gaining weight back, focus on adopting a healthy eating pattern long-term, similar to the principles of a Mediterranean or Longevity Diet. Emphasize whole, plant-based foods, and continue to avoid excessive processed foods and sugar.
