What are the Best Fasts to Reset Digestion?

The best fasts to reset digestion are structured periods when you limit or abstain from food, giving your digestive system a much-needed rest. There are several ways to do this, ranging from gentle (like 12-hour overnight fasting) to more advanced (like 24-hour resets or prolonged fasts), all aimed at reducing digestive workload and letting your gut repair itself.

Quick Glance:
  • Intermittent fasting (IF): Eating within a set window—commonly 16 hours fasting, 8 hours eating (16:8 pattern)
  • Time-Restricted Eating: Fast for 12-14 hours overnight
  • 24-Hour Fasts: Once-a-week resets for experienced fasters
  • Fasting Mimicking Diets (FMD): Low-calorie, plant-based "fasting" for up to 5 days
  • Juice or Broth Fasts: Short-term resets using filtered fruit/veggie juices or bone broths

Each of these supports your body's natural cleaning process (autophagy), reduces inflammation, and can reboot your gut microbial balance.

Why Gut Reset Matters for Your Health & Well-Being

  • Better Dysbiosis Reset: Digestive fasts help re-balance your gut microbiome
  • Reduced Inflammation: Fasting can lower inflammatory markers in your digestive tract
  • Relief from Bloating, Cramping, and Gas: Giving your gut a break minimizes discomfort
  • Clearer Mind, Improved Mood: Gut and brain are closely linked—happy gut, happy mind!
  • Enhanced Immunity: 70% of your immune system is in the gut

Common Challenges & Myths About Fasting and Digestion Reset

  • Myth 1: "Fasting will slow down my metabolism."
    Fact: Short-term fasting (12-48 hours) can actually enhance metabolic flexibility and is not harmful. Prolonged fasting without guidance may have risks.
  • Myth 2: "I’ll feel weak or starve myself."
    Fact: Most people adapt quickly. Start slow and listen to your body.
  • Challenge: Hunger pangs and irritability.
    Try hydration, herbal tea, or a light walk.
  • Myth 3: "Fasting is unsafe for everyone."
    Fact: Most healthy adults can try simple fasts, but it’s not recommended for pregnant women, children, those with eating disorders, or chronic conditions without medical supervision.

Step-By-Step: How to Try Fasting to Reset Digestion

  1. Pick Your Reset Type: Start with what feels manageable (e.g., 12-hour overnight fast—it’s just no eating after dinner until breakfast).
  2. Prepare:
    • Taper caffeine, minimize processed foods, and hydrate well the day before
    • Plan gentle physical activities (yoga, walking) and relaxing routines
  3. During the Fast:
    • Drink water, herbal tea, or plain bone broth
    • Avoid artificial sweeteners or juices (unless juice fasting)
    • Listen to your body—mild hunger is normal; severe discomfort means pause and eat something nourishing
  4. Breaking the Fast:
    • Reintroduce foods slowly—start with steamed veggies, broths, or fresh fruit
    • Avoid high-fat, high-sugar, or processed meals immediately
  5. Integrate Learnings:
    • Notice improved digestion, energy, and mood—and repeat resets as needed

Expert Tips & Scientific Backing

  • Scientific Insight: A 2019 review in Cell Metabolism found that intermittent fasting positively impacts the gut microbiome and supports intestinal health (source).
  • Expert Tip: Dr. Will Bulsiewicz, gastroenterologist, recommends starting with shorter fasts and consuming more fiber-rich, plant-based foods between fasts to keep your gut microbes diverse and happy.
  • Bonus: Pair fasting with mindful stress management (breathwork, meditation)—stress can disrupt gut reset effects.
