What to eat in the morning during intermittent fasting?

4 min read

According to research published in the journal Food and Nutrition Research, time-restricted feeding is a popular form of intermittent fasting. For those practicing this method, understanding what to eat in the morning during intermittent fasting is crucial to maintain metabolic benefits and support health goals.

Quick Summary

The morning routine in intermittent fasting depends on whether you are in your fasting or eating window. During the fast, consume only zero-calorie beverages. For the first meal of your eating window, prioritize easily digestible, nutrient-dense foods to ease digestion and promote satiety.

Key Points

  • Differentiate Fasting vs. Eating: The morning is either for zero-calorie intake during the fasting window or a careful, gentle reintroduction of food during the eating window.

  • Choose Zero-Calorie Fluids: Water, black coffee, and plain herbal tea are safe to drink during your fasting period without breaking it.

  • Break Fast Gently: Your first meal should be small, easily digestible, and nutrient-dense to avoid shocking your system.

  • Prioritize Protein and Healthy Fats: These nutrients promote satiety and sustained energy, preventing blood sugar crashes that sugary carbs can cause.

  • Avoid Sugary and Heavy Foods Initially: Refrain from high-sugar foods, heavy red meat, or large amounts of raw fiber in your first meal to prevent digestive upset.

  • Focus on Balanced Meals: Combine protein (eggs, yogurt), healthy fats (avocado, nuts), and moderate fiber (berries, cooked veggies) for a well-rounded start.

The Morning Fasting Window: What to Consume

Many intermittent fasting schedules, such as the popular 16:8 method, mean that the morning is part of your fasting window. During this time, it is critical to avoid anything that contains calories, as this will break your fast. The body shifts from burning sugar for energy to burning stored fat during a fast, a process called ketosis, and consuming calories interrupts this.

Safe Morning Beverages

To stay hydrated and curb hunger without breaking your fast, you can enjoy these beverages:

  • Water: Plain water is always the best choice and should be consumed consistently throughout your fasting period. Adding a pinch of Himalayan pink salt can help replenish electrolytes.
  • Black Coffee: Unsweetened black coffee is generally fine, with its caffeine potentially boosting your metabolism. Some advanced fasters might add a small amount of MCT oil or grass-fed butter (known as Bulletproof Coffee) for sustained energy, but this is a gray area and does add calories, so it's not strictly a 'fasted' state.
  • Herbal Tea: Unsweetened herbal teas, like green tea, can offer antioxidants and keep you hydrated. Avoid adding milk or sugar.
  • Apple Cider Vinegar: A small amount of apple cider vinegar in water is sometimes used to help curb appetite, but it's important to keep the quantities minimal.

Breaking Your Fast in the Morning

When your eating window begins, breaking your fast with the right foods is key to preventing a blood sugar spike and digestive discomfort. After a period of fasting, your digestive system is in a sensitive state, so ease back in gently.

The Best Foods to Break a Morning Fast

Focus on easily digestible, nutrient-dense foods that provide a balance of protein, healthy fats, and fiber.

  • Eggs: A powerhouse of protein and nutrients. Scrambled or soft-boiled eggs are gentle on the stomach and provide sustained energy.
  • Greek Yogurt with Berries and Nuts: Greek yogurt is rich in probiotics for gut health and protein for satiety. Berries provide antioxidants and fiber, while nuts offer healthy fats.
  • Avocado Toast: For those who tolerate grains well, avocado on whole-grain toast provides healthy fats and fiber. Pairing it with an egg adds protein.
  • Smoothies: A simple smoothie with a banana, spinach, almond milk, and a scoop of protein powder is easily digestible and nutrient-packed.
  • Bone Broth: Especially after longer fasts, starting with bone broth can be a gentle way to reintroduce nutrients and fluids.

Foods to Avoid When Breaking a Fast

Some foods can be a shock to your system after fasting. For your first meal, it's best to avoid:

  • High-Sugar Foods: Sugary cereals, pastries, and sweetened juices can cause a significant blood sugar spike and subsequent crash.
  • Heavy, Fatty Meals: Large, greasy meals require more effort to digest and can cause digestive upset. Red meat, being harder to digest, is best saved for a later meal.
  • Excessive Raw Fiber: While fiber is good, a large quantity of raw, fibrous vegetables (like broccoli) can be harsh on the gut. Steamed or blended vegetables are a better option.

Morning Meal Comparison for Intermittent Fasting

Feature Good Fast-Breaking Meal (e.g., Eggs & Avocado) Poor Fast-Breaking Meal (e.g., Sugary Cereal)
Nutrient Balance High in protein, healthy fats, and moderate fiber. High in refined carbs and sugar; low in protein.
Energy Release Slow, sustained energy release. Rapid blood sugar spike and quick energy crash.
Digestion Gentle and easy to digest. Can cause bloating, gas, and digestive discomfort.
Satiety Keeps you feeling full longer due to protein and fat. Increases hunger and cravings shortly after eating.
Gut Health Supports gut health with probiotics and fiber. Can disrupt blood sugar and gut balance.

How to Build a Complete Morning Meal

Building a balanced morning meal after fasting is simple with the right strategy. Follow these steps to ensure a smooth transition and lasting energy:

  1. Hydrate First: Before you eat, drink a glass of water to rehydrate and signal your body. You can add a pinch of salt or a squeeze of lemon.
  2. Start with Gentle Solids: Begin with a small portion of easily digestible food. A small amount of Greek yogurt, a few bites of scrambled egg, or a cup of bone broth can be a good starting point.
  3. Incorporate Protein and Fat: Add a source of lean protein and healthy fat. This combination promotes satiety and provides steady energy. Think about an egg, a piece of salmon, or a handful of nuts.
  4. Add Complex Carbs (Optional): If you are not on a low-carb diet, you can add some complex carbohydrates, such as a serving of sweet potato or a small portion of quinoa, after your protein and fat.
  5. Finish with Fiber: Include some fruits or cooked non-starchy vegetables for fiber and micronutrients.

Conclusion

Ultimately, knowing what to eat in the morning during intermittent fasting is about understanding your schedule and listening to your body. During your fasting window, stick to zero-calorie drinks like water and black coffee. When it's time to break your fast, prioritize easily digestible, nutrient-dense foods like eggs, Greek yogurt, or a protein-rich smoothie. By making mindful, balanced choices, you can ease your digestive system back into action, support your health goals, and feel energized for the day ahead.

Frequently Asked Questions

No, black coffee does not typically break a fast because it contains a negligible amount of calories. It is a common beverage during the fasting window.

Yes, Greek yogurt is an excellent choice for breaking a morning fast. It provides probiotics and is high in protein, which helps with satiety and is gentle on the stomach.

For longer fasts, it is best to start with easily digestible, hydrating foods like bone broth, simple smoothies, or steamed vegetables to ease your digestive system back into action.

Sugary foods cause a rapid spike in blood sugar and insulin levels, which can negate the metabolic benefits of fasting and lead to an energy crash shortly after.

No, adding milk or cream to your coffee introduces calories and fat, which will break your fast. Stick to black coffee or herbal tea during the fasting window.

High-fiber vegetables can be difficult to digest right after a fast. It is better to have them cooked and in moderation as part of a larger, balanced meal, rather than your very first food.

It's best to ease into your meal. Start with a small, digestible portion, and wait 30-60 minutes before consuming a larger, more complex meal to allow your body to readjust.
