The Critical First 12 Hours: ProLon's Transition Day (Day 6)
After five days of a fasting-mimicking diet, your digestive system is in a rested state. The first 12 hours, known as the transition day, are crucial for a gentle restart. ProLon recommends avoiding rich or heavy meals and starting with soft, liquid-based foods.
Morning: Rehydration and Gentle Liquids
Begin your day with liquids that hydrate and nourish without overwhelming your system. These are excellent choices:
- Water and Herbal Tea: Crucial for rehydration. Continue to drink plenty throughout the day.
- Bone or Vegetable Broth: Low-sodium broths provide a gentle way to reintroduce minerals and flavor.
- Simple Smoothies: A simple smoothie with a small amount of fruit and liquid can be an excellent first food. Consider ripe bananas, melon, or berries blended with water or unsweetened almond milk. Avoid high-fiber additions like oats initially.
Afternoon and Evening: Introducing Light Solids
As the day progresses, you can introduce small, light meals. Focus on cooked, easy-to-digest whole foods. ProLon suggests starting with:
- Cooked Vegetables: Lightly steamed or boiled vegetables like zucchini, carrots, spinach, or winter squash are ideal.
- Grains: Small portions of cooked white rice or whole grain pasta are acceptable.
- Small Portions of Protein: Easily digestible proteins such as beans, lentils, or fish can be introduced.
Days 7 and Beyond: Gradually Resuming Regular Eating
After the initial transition day, you can continue to expand your diet, gradually increasing portion sizes and variety. This is the ideal time to adopt the long-term healthy eating habits that will sustain your results.
Incorporating a Longevity Lifestyle
ProLon advises adopting a long-term Longevity Diet, based on the eating habits of centenarians. This typically includes:
- Mostly Plant-Based Diet: Focus on whole, plant-based foods.
- Smaller Portions: Continue to practice portion control.
- Reduced Processed Foods: Minimize or eliminate alcohol and processed foods.
Recommended Foods for Post-Fast
- Lean Protein: Skinless chicken, fish, tofu, and legumes are excellent choices.
- Healthy Fats: Incorporate avocados, nuts, and seeds.
- Fruits and Vegetables: Reintroduce a wide variety of fruits and vegetables, including some raw options, as your body feels comfortable.
What to AVOID Immediately After the ProLon Fast
Just as important as what you should eat is what you should avoid. Overwhelming your digestive system with heavy, hard-to-digest foods can cause significant discomfort and negate some of the fast's benefits.
- Heavy, Fatty, or Greasy Foods: Red meat and fried foods should be avoided in the first few days as they are difficult to digest.
- Excessive Sugar and Refined Carbs: These can cause a blood sugar spike after a period of limited intake.
- Excessive Fiber: While healthy, too much raw, high-fiber produce can upset a delicate stomach. Cooked vegetables are a safer starting point.
- Dairy Products: Some individuals find dairy difficult to digest after a fast. Consider unsweetened plant-based alternatives initially.

The Psychology of Refeeding and Long-Term Success
After a prolonged fast, food can seem incredibly appealing, but it's important to practice mindful eating. Slow down, chew thoroughly, and listen to your body's signals of fullness to avoid overeating and bloating. This period is a great opportunity to reset your palate and form a better relationship with food, appreciating its natural flavors and nourishing qualities. Focusing on nutritious whole foods can help break unhealthy eating cycles and sustain the progress you've made during the fast. Adopting a consistent, healthy eating pattern post-fast, such as a circadian eating pattern, helps maximize your long-term health and longevity. The fast is the start, but the refeeding is the bridge to lasting wellness. For more details on the Fasting Mimicking Diet principles, consult the ProLon website.
Conclusion
Breaking a 5-day ProLon fast correctly is just as important as completing the fast itself. The key is to reintroduce food gently, starting with simple liquids and soft, digestible foods on Day 6. Gradually expanding your diet over the next few days with whole foods, lean proteins, and healthy fats will help avoid digestive distress and maximize the health and longevity benefits of your fast. By transitioning mindfully and adopting a healthier long-term diet, you can turn your fast into a powerful stepping stone toward sustained wellness and a healthier lifestyle.
