Intermittent fasting (IF) is a popular eating pattern that involves cycling between periods of eating and fasting. While many people focus on when to eat with intermittent fasting, what to eat is just as important. The right diet can maximize the benefits of intermittent fasting, from weight loss to improved health.
In this article, we will explore the best diets to follow when practicing intermittent fasting, and why these eating plans work so well with fasting.
What Is Intermittent Fasting?
Intermittent fasting is not a specific diet but rather an eating schedule. The most common forms include:
- 16/8 method: Fasting for 16 hours and eating within an 8-hour window.
- 5:2 method: Eating normally for 5 days and restricting calories to 500-600 on 2 non-consecutive days.
- 24-hour fast: Fasting for a full 24 hours once or twice a week.
The idea is to allow the body time to burn fat during the fasting periods, which can lead to weight loss and other health benefits. However, the effectiveness of intermittent fasting largely depends on the quality of food consumed during eating periods.
Why Diet Matters with Intermittent Fasting
The body needs nutrients to function optimally, and what you eat during your eating window will impact how you feel and perform. If you consume unhealthy, processed foods, your energy levels may dip, and you might not lose weight as effectively.
A good diet can help:
- Support your energy levels.
- Keep hunger at bay during fasting.
- Improve metabolism and fat-burning.
- Provide the necessary vitamins and minerals for overall health.
Key Features of a Diet for Intermittent Fasting
Here are some key characteristics to look for in a diet that works well with intermittent fasting:
- High in protein: Protein helps with satiety, muscle repair, and fat loss.
- Rich in healthy fats: Healthy fats, like those from avocado or olive oil, provide long-lasting energy.
- Low in refined carbohydrates: Avoiding sugars and processed carbs can prevent insulin spikes and crashes.
- Packed with fiber: Fiber from vegetables and whole grains aids digestion and keeps you full longer.
- Nutrient-dense: A good diet for intermittent fasting should be filled with vitamins, minerals, and antioxidants.
Now, let’s dive into some specific diets that complement intermittent fasting.
The Mediterranean Diet
What is the Mediterranean Diet?
The Mediterranean diet is inspired by the traditional eating habits of countries around the Mediterranean Sea, such as Greece and Italy. It emphasizes whole, plant-based foods, healthy fats, and moderate protein intake, mainly from fish.
Why It Works with Intermittent Fasting
- Healthy fats for sustained energy: Foods like olive oil, nuts, and seeds provide healthy fats that keep you full longer during fasting periods.
- High in fiber: The diet includes whole grains, legumes, and vegetables that help with digestion and control hunger.
- Moderate protein: Fish and lean meats offer enough protein to preserve muscle while losing fat.
- Antioxidants for health: Rich in fruits and vegetables, this diet provides antioxidants that support overall health and reduce inflammation.
The Mediterranean diet’s emphasis on whole, unprocessed foods makes it a perfect partner for intermittent fasting.
Low-Carb Diet
What is a Low-Carb Diet?
A low-carb diet limits carbohydrates, such as those found in sugary foods, pasta, and bread. Instead, you eat foods rich in protein and fat.
Why It Works with Intermittent Fasting
- Stable blood sugar levels: By reducing carbs, you avoid spikes and crashes in blood sugar, making it easier to fast.
- Fat adaptation: Your body becomes more efficient at burning fat for energy, especially during fasting periods.
- Satisfying meals: Protein and fats are more filling than carbohydrates, which helps control hunger.
A low-carb diet can help enhance the fat-burning effects of intermittent fasting and improve insulin sensitivity.
Ketogenic (Keto) Diet
What is the Keto Diet?
The keto diet is an ultra-low-carb, high-fat diet that shifts your body into a state of ketosis, where it burns fat for energy instead of carbohydrates.
Why It Works with Intermittent Fasting
- Enhanced fat burning: Since your body is already in fat-burning mode (ketosis), combining it with fasting boosts fat loss even further.
- Less hunger: High-fat foods are very satisfying, which makes fasting easier.
- Improved focus: Ketones, produced during ketosis, are a great fuel for the brain, providing mental clarity.
Intermittent fasting and the keto diet are often paired together because they both help the body rely on fat as a primary energy source.

Whole Foods, Plant-Based Diet
What is a Whole Foods, Plant-Based Diet?
This diet emphasizes whole, minimally processed plant foods such as vegetables, fruits, legumes, whole grains, nuts, and seeds. It excludes or minimizes animal products and processed foods.
Why It Works with Intermittent Fasting
- Nutrient-dense: Plant-based diets are packed with vitamins, minerals, and antioxidants, helping to nourish your body during eating windows.
- High in fiber: Fiber helps keep you full, promotes healthy digestion, and balances blood sugar.
- Low-calorie, high-volume: Plant-based foods like vegetables and fruits are naturally low in calories but high in volume, meaning you can eat a lot without over-consuming calories.
A whole foods, plant-based diet supports overall health and makes fasting more manageable due to its high nutrient and fiber content.
Paleo Diet
What is the Paleo Diet?
The paleo diet focuses on foods that our hunter-gatherer ancestors would have eaten, such as lean meats, fish, fruits, vegetables, nuts, and seeds. It excludes processed foods, grains, dairy, and legumes.
Why It Works with Intermittent Fasting
- Nutrient-dense: The paleo diet provides plenty of vitamins and minerals through whole foods.
- Protein-packed: The focus on lean meats ensures that you get enough protein to maintain muscle mass while fasting.
- Reduced cravings: Eliminating processed foods and sugars helps reduce hunger and makes fasting easier.
The paleo diet works well with intermittent fasting because it emphasizes whole, natural foods that support fat loss and energy levels.
The DASH Diet
What is the DASH Diet?
DASH stands for Dietary Approaches to Stop Hypertension. This diet focuses on foods that help lower blood pressure, such as fruits, vegetables, lean proteins, and low-fat dairy. It’s low in sodium, saturated fats, and added sugars.
Why It Works with Intermittent Fasting
- Heart-healthy: The DASH diet is designed to improve cardiovascular health, which complements the benefits of intermittent fasting.
- Balanced nutrition: It includes a variety of food groups, ensuring you get a good mix of nutrients during eating periods.
- Weight loss-friendly: It’s naturally lower in calories, which supports weight loss goals when combined with fasting.
The DASH diet is particularly good for those looking to improve heart health while practicing intermittent fasting.
Combining Fasting with Your Chosen Diet
Regardless of which diet you choose, here are some tips to optimize your intermittent fasting experience:
- Stay hydrated: Drink plenty of water, herbal teas, or black coffee during fasting periods to stay hydrated and curb hunger.
- Eat nutrient-dense meals: Focus on whole, unprocessed foods that provide a balance of protein, healthy fats, and complex carbs.
- Avoid overeating: It can be tempting to overeat during your eating windows, but try to stick to portion-controlled meals.
- Plan ahead: Prepare your meals in advance to ensure that you have healthy options ready when your eating window opens.
Conclusion
The best diet to pair with intermittent fasting is one that emphasizes whole, nutrient-dense foods, provides enough protein and healthy fats, and is low in processed carbs and sugars. Whether you choose the Mediterranean diet, low-carb, keto, plant-based, paleo, or DASH, the key is to eat foods that fuel your body and support your fasting routine.
