What is the best thing to eat after not eating?

4 min read

Many people experience gastrointestinal discomfort when they resume eating after a period of fasting or illness, because the digestive system slows down during prolonged periods without food. To avoid an upset stomach and support a smooth recovery, selecting the right foods is crucial. This guide provides a strategic approach to safely reintroducing nutrition to your body.

Quick Summary

Safely reintroducing food after not eating requires starting with hydrating, easy-to-digest options and small portions. Gradually introduce nutrient-dense solids while avoiding heavy, fatty, or sugary foods to prevent digestive distress and an energy crash. The refeeding process should be gentle to allow the digestive system to reactivate properly.

Key Points

  • Start Slow: Begin with small, frequent portions to prevent overwhelming your digestive system, which is in a dormant state.

  • Prioritize Hydration: Sip on water, clear broths, or herbal teas to replenish fluids and electrolytes gently.

  • Choose Easy-to-Digest Foods: Opt for bland, low-fiber options like bananas, white rice, and toast to ease your stomach back into processing food.

  • Avoid Problematic Foods: Steer clear of fatty, sugary, spicy, and high-fiber foods initially, as they can cause digestive distress.

  • Consider Probiotics: Once you can tolerate bland foods, introduce probiotic-rich options like plain yogurt or kefir to support your gut microbiome.

  • Listen to Your Body: Pay close attention to how you feel after eating and adjust your intake accordingly; increase portion sizes and food variety gradually.

Why Your First Meal Matters

After a period of not eating, for reasons ranging from a short-term stomach bug to a planned fast, your body’s digestive system is in a dormant state. Enzyme production slows down, and your body shifts from processing glucose from food to relying on stored fat for energy. When you introduce food, your system needs time to reactivate and adjust. Eating a large, heavy meal too quickly can overwhelm your stomach and lead to discomfort, bloating, and nausea. In severe cases, particularly for those who have been significantly malnourished, a rapid increase in food intake can lead to a dangerous condition known as refeeding syndrome, caused by potentially fatal shifts in fluids and electrolytes. A gentle and mindful approach is always the safest method.

The Best Foods to Start With

To ensure a smooth transition back to eating, focus on foods that are gentle, easy to digest, and offer hydration and essential nutrients. This graduated approach helps prevent shock to your system.

Liquid Refreshments and Broths

Begin by rehydrating and providing a small, easily absorbable source of nutrients.

  • Bone or Vegetable Broth: Rich in minerals and gentle on the stomach, broth helps replenish electrolytes and fluids without overwhelming your digestive system.
  • Clear Fluids: Water, diluted fruit juice, or herbal teas like ginger or peppermint are excellent for rehydration and soothing the stomach.
  • Simple Smoothies: A smoothie with low-fiber fruits like ripe banana and liquid such as coconut water or unsweetened milk can be a gentle way to get nutrients. Avoid adding protein powders or too many fibrous ingredients at first.

Easy-to-Digest Solids

Once clear liquids are tolerated, move on to bland, soft solids.

  • Bananas: Rich in potassium and easy to digest, ripe bananas are a great source of gentle carbohydrates.
  • White Rice and Plain Toast: Part of the classic BRAT diet, these low-fiber options are simple starches that can help settle an upset stomach.
  • Cooked Starchy Vegetables: Steamed or mashed carrots, zucchini, and sweet potatoes are easy to digest and provide essential vitamins.
  • Eggs: For a lean protein, eggs (especially scrambled or soft-boiled) are an excellent and digestible choice.

Gut-Supporting Fermented Foods

After a few small, bland meals, introducing fermented foods can help restore the beneficial bacteria in your gut microbiome.

  • Plain Yogurt or Kefir: A great source of probiotics, unsweetened yogurt or kefir helps improve digestion and gut health.
  • Pickled Vegetables: Small amounts of sauerkraut or kimchi can introduce healthy bacteria to your system.

Foods and Drinks to Avoid After Not Eating

Just as important as knowing what to eat is knowing what to avoid. Certain foods can easily trigger digestive upset after a period of rest.

  • High-Fat and Fried Foods: Greasy, fatty foods are difficult to digest and can lead to nausea and discomfort.
  • High-Fiber Foods: While healthy, raw vegetables and legumes can be hard on a sensitive stomach. Reintroduce these gradually.
  • Sugary Drinks and Sweets: Refined sugars can cause a rapid spike and crash in blood sugar, putting a strain on your system.
  • Spicy Foods: Hot sauce and other spicy items can irritate the stomach lining and should be avoided.
  • Alcohol and Caffeine: These can irritate the digestive tract and should be avoided during the recovery period.
  • Acidic Foods: Citrus fruits and tomatoes can be harsh on an empty or sensitive stomach.

A Gradual Refeeding Plan

This sample plan outlines a safe reintroduction of food over a few days, depending on the length and reason for not eating.

Day 1: Liquids and Small Sips Focus on hydration. Sip water, broth, or herbal tea frequently. If tolerating well, introduce a simple, low-sugar smoothie.

Day 2: Bland and Soft Solids Eat small portions of easy-to-digest foods like bananas, plain rice, or toast. Continue to hydrate and listen to your body’s signals.

Day 3: Introducing Lean Proteins and Probiotics Add a small serving of lean protein, such as soft-boiled eggs or baked fish. Introduce a small amount of unsweetened yogurt or kefir to support gut health.

Day 4+: Reintroducing a Normal Diet Slowly add more variety and fiber. Introduce cooked vegetables, and eventually, whole grains and other items, monitoring how your body responds to each new food. Avoid processed and heavy foods for at least a week.

Conclusion: Listen to Your Body

Restarting your eating habits after a period of abstaining requires patience and a cautious approach. By prioritizing gentle, hydrating, and easy-to-digest foods, you can ease your digestive system back into function and avoid unnecessary discomfort. Starting with small portions and gradually building up your intake, while avoiding foods that can cause irritation, is the safest way to refuel your body. Always pay attention to your body’s cues and seek professional medical advice for prolonged periods of not eating or if you experience concerning symptoms.

Important Safety Note

If you have been seriously malnourished or have not eaten for several days due to illness, you may be at risk for refeeding syndrome. It is crucial to consult a healthcare professional, such as a doctor or registered dietitian, to ensure you reintroduce food safely and receive appropriate medical monitoring if necessary.

Frequently Asked Questions

After not eating, the first thing you should consume is water or clear broth. This helps rehydrate your body and replenish fluids and electrolytes gently, preparing your stomach for food.

Good examples of bland foods include ripe bananas, plain rice, white toast, applesauce, and cooked, low-fiber vegetables like steamed carrots or zucchini.

This depends on the duration of not eating and how you feel. For a day or two of fasting, a day or two of bland foods may be enough. For a longer period, it's safer to follow a gradual reintroduction plan over several days, increasing variety as your symptoms improve.

Fatty and fried foods are harder to digest, especially for a system that's been dormant. Introducing them too soon can overwhelm your stomach and cause cramping, bloating, and other discomfort.

A simple, low-fiber smoothie made with ingredients like ripe banana and coconut water can be a gentle way to reintroduce nutrients. However, avoid thick, heavy, or high-fiber smoothies, which can be too much for your system initially.

Even after a short fast, it is best to transition gradually with small, easy-to-digest meals rather than jumping straight into a large, normal meal. This helps prevent digestive distress and manages blood sugar spikes.

If you feel nauseous, stop eating solid foods and revert to sipping clear fluids like water or ginger tea. Small sips and chewing ice chips can help. You can try a small amount of bland food again later when you feel better.
