4 min read

Recent studies from Johns Hopkins have highlighted the numerous health benefits of intermittent fasting, from improved metabolic health to weight management. However, as the practice gains popularity, understanding what's the best thing to eat while fasting is critical, as the way you break your fast is just as important as the fast itself.

Quick Summary

This guide covers the best foods to eat when breaking a fast, focusing on easily digestible, nutrient-dense options like lean protein, healthy fats, and hydrating fruits. It also highlights foods to avoid and provides practical tips for a gentle transition back to eating.

Key Points

  • Start Gently: Break your fast with small portions of easily digestible foods to avoid shocking your digestive system.

  • Prioritize Hydration: Replenish fluids and electrolytes with water, bone broth, or coconut water, especially after a longer fast.

  • Choose Whole Foods: Focus on nutrient-dense options like lean protein, healthy fats, and cooked vegetables, which provide sustained energy.

  • Avoid Processed and Sugary Foods: Steer clear of junk food, sugary drinks, and heavy, greasy meals to prevent blood sugar spikes and bloating.

  • Listen to Your Body: Pay attention to your hunger and fullness cues, eating mindfully and slowly to prevent overeating and discomfort.

  • Support Gut Health: Incorporate fermented foods like yogurt or kefir to help restore beneficial gut bacteria after a period of fasting.

Understanding the Importance of Breaking a Fast Gently

Fasting, whether for religious reasons or health benefits like intermittent fasting, puts your digestive system in a state of rest. When you reintroduce food, it’s a shock to your system that needs to be managed carefully to avoid discomfort, blood sugar spikes, and bloating. The best approach is to start with small portions of easily digestible, nutrient-dense foods and gradually increase your intake as your body adjusts. This mindful refeeding supports the body's repair processes and helps maximize the benefits of your fast.

The Best Foods to Eat After Fasting

1. Hydrating, Electrolyte-Rich Fluids

After a period of fasting, dehydration can be a concern, making rehydration your top priority. While drinking water throughout your fast is recommended, breaking it with specific fluids can be extra beneficial.

  • Bone Broth: This is an excellent first option, especially after a prolonged fast. It is rich in electrolytes and contains partially broken-down proteins like collagen, making it easy to digest and soothing for the gut. You can easily make your own or find natural, organic versions at stores.
  • Coconut Water: A natural source of electrolytes like potassium and magnesium, coconut water helps replenish lost minerals and rehydrate the body effectively without a high sugar load.
  • Infused Water: Water infused with lemon, mint, or cucumber can add flavor and extra nutrients while keeping you hydrated.

2. Easily Digestible Proteins

Reintroducing protein is important for muscle maintenance and satiety, but starting with easily digestible sources is key.

  • Eggs: A complete source of protein, eggs are packed with vitamins and minerals. Whether scrambled or hard-boiled, they are gentle on the digestive system and highly satiating.
  • Fish: Lean fish like salmon or cod offers high-quality protein and beneficial omega-3 fatty acids, which can help reduce inflammation. Grilling or baking is preferable to frying.
  • Lean Poultry: Small amounts of lean chicken or turkey breast can be a good option, especially after an overnight or shorter fast.

3. Healthy Fats for Satiety

Incorporating healthy fats can help you feel full and satisfied, preventing overeating after your fast.

  • Avocado: Rich in monounsaturated fats, dietary fiber, and essential minerals, avocado is exceptionally satiating and easy to digest.
  • Nuts and Seeds: Almonds, chia seeds, and flaxseeds provide healthy fats and fiber, offering sustained energy. Start with smaller portions to avoid overwhelming your system.

4. Gentle Carbohydrates and Fiber

While simple carbs can spike blood sugar, complex, easily digestible options provide sustained energy.

  • Cooked Vegetables: Cooking breaks down tough fibers, making vegetables like spinach, carrots, and sweet potatoes easier on the stomach than raw versions.
  • Low-Sugar Fruits: Berries, melons, and apples are rich in water, vitamins, and minerals. The fiber helps regulate the absorption of natural sugars, preventing a rapid blood sugar rise.
  • Oats or Brown Rice: After a short fast, cooked oats or brown rice can provide excellent fiber and complex carbohydrates.

5. Probiotic-Rich Fermented Foods

Fermented foods help repopulate the gut with beneficial bacteria, which is crucial for healthy digestion, especially after a period of rest.

  • Yogurt or Kefir: Unsweetened versions are rich in probiotics and are gentle on the stomach.
  • Miso or Tempeh: These fermented soy products are also excellent for gut health and can be incorporated into soups or stir-fries.

What to Avoid When Breaking a Fast

Equally important is knowing what to steer clear of, especially in the first few hours after your fast concludes.

  • Processed and Sugary Foods: Avoid junk food, packaged snacks, and sugary drinks. They can cause a sharp insulin spike and lead to an energy crash.
  • Heavy, Fatty Meals: Large, greasy meals or rich, fatty cuts of meat can be difficult for your digestive system to process and can cause bloating or indigestion.
  • Excessive Amounts: The urge to overeat is common after a fast, but it can cause digestive upset. Start small and chew your food thoroughly.
  • High-Fiber Raw Vegetables: While healthy normally, large quantities of raw, fibrous vegetables can be too harsh for an empty stomach. Opt for cooked versions initially.

Comparison Table: Gentle vs. Harsh Fast-Breaking Foods

Feature Gentle Options Harsh Options
Initial Fluid Bone broth, coconut water, infused water Sugary soda, fruit juice, milky coffee
First Protein Eggs, lean fish, yogurt, miso Fatty red meat, deep-fried chicken, protein shakes
First Carbs Cooked spinach, sweet potato, oats, berries White bread, pasta, sugary cereal, pastries
First Fats Avocado, small handful of nuts/seeds Greasy fried foods, heavy cream, excessive butter
Gut Support Fermented foods like yogurt, kefir Processed junk food, sugary treats

Conclusion: Mindful Eating is Key

The way you break your fast profoundly impacts your body's response and your overall well-being. By choosing nutrient-dense, easily digestible foods like bone broth, lean proteins, healthy fats, and hydrating fruits, you can gently ease your digestive system back into action. Prioritize hydration, eat mindfully, and avoid the temptation of processed or heavy foods. The goal is to nourish your body, not shock it.

Frequently Asked Questions

During a fast, you can typically drink water, black coffee, and unsweetened tea. Calorie-free beverages are usually safe. However, adding sugar, cream, or milk will break a fast.

Yes, black coffee is generally considered fine during a fast. With only about 3 calories per cup, it does not typically induce a metabolic change significant enough to break your fast. Just be sure to avoid added sugars or creams.

Supplements containing calories, sugar, or significant protein can break a fast. Generally, calorie-free multivitamins, fish oil, and creatine are safe. Always check ingredients, as gummy vitamins and protein powders usually break a fast.

Yes, fruit is a great option. Low-sugar, water-rich fruits like berries and melons are ideal because they help with rehydration. The fiber in fruits helps slow the absorption of natural sugars.

Breaking a fast slowly gives your digestive system time to wake up and produce the necessary enzymes for digestion. Eating too quickly or too much can lead to bloating, discomfort, and blood sugar spikes.

Refeeding syndrome is a potentially fatal shift in fluids and electrolytes that can occur in malnourished individuals after receiving artificial feeding. You can help avoid imbalances by breaking your fast slowly with small portions of nutrient-dense food, especially those rich in electrolytes.

No, you should not avoid all carbohydrates. Opt for complex, easily digestible carbs like cooked oats, sweet potatoes, or brown rice. These provide sustained energy without the rapid blood sugar spike caused by simple carbs.
