In recent years, there has been a growing interest in exploring new dietary approaches that promote health and reflect personal and ethical values. In this context, intermittent fasting and veganism have captured the attention of those who are seeking a balance between physical well-being and environmental consciousness.
These trends invite reflection on how our food choices can influence our lifestyle and the world around us. Throughout this text, we’ll explore how these practices can be integrated to maximize their potential benefits.
In the world of dietary trends, vegan intermittent fasting stands out as an option that promises health benefits and resonates with those who are seeking a more conscious and ethical lifestyle. Before we delve into this practice, it’s helpful to understand the two pillars that support it: intermittent fasting and veganism.
Intermittent Fasting
Intermittent fasting is an eating pattern that focuses on when to eat, alternating between periods of eating and fasting. This method can help with weight loss, as it results in reduced overall calorie intake. Studies have found it to be equivalent to calorie restriction in its effectiveness for weight loss (1). In addition, many people find it useful for simplifying their meal planning.
This approach offers a variety of methods, each of which has its own unique timing and structure. Consider exploring these approaches to identify one that aligns with your lifestyle and health goals. It’s wise to consult a healthcare professional to ensure the method you choose is safe and suitable for your circumstances.
Veganism
The vegan diet is a type of eating within the vegetarian spectrum that excludes all animal-derived products. This includes dairy, eggs, and honey, unlike other vegetarian variants that may allow the consumption of some of these products. It focuses exclusively on plant-based foods such as fruits, vegetables, legumes, grains, nuts, and seeds. This approach has health and environmental benefits and is aligned with ethical principles of animal welfare (2).
With these concepts in mind, we can explore how they combine to form vegan intermittent fasting. It’s an approach that aims to maximize the benefits of both methods for overall health and well-being. Many individuals experience positive results of vegan intermittent fasting such as increased energy, improved digestion, and greater mental clarity. In addition, some have noted benefits such as weight loss and metabolic improvements, which could further contribute to a healthier lifestyle (3).

Yes, you can practice intermittent fasting as a vegan. Some believe that this combination offers numerous benefits for health and overall well-being. The main focus of intermittent fasting should not solely be on the fasting hours. It should also include what you consume during the eating periods. It’s important to ensure all your nutritional needs are met during these times.
This involves prioritizing protein-rich foods such as legumes, tofu, tempeh, and edamame. They are essential for maintaining muscle mass, energy, and cellular repair (4) (5). It’s also important to include a wide variety of fruits and vegetables, which provide essential vitamins, minerals, and antioxidants for optimal body function (6).
We mustn’t forget healthy fats. They can be obtained from sources such as avocados, nuts, seeds, and vegetable oils such as olive or flaxseed oil (7). Similarly, complex carbohydrates from whole grains such as quinoa, brown rice, and oats are essential for providing sustained energy throughout the day (8).
Planning your meals in a balanced way during eating periods can help you maximize the benefits of intermittent fasting while following a vegan diet. This will help ensure that your body receives all the necessary nutrients to function optimally and allow you to enjoy a variety of flavors and textures in your meals, which will make the process more enjoyable and sustainable in the long term.
It is advisable to seek guidance from a healthcare professional to determine which type of fasting, if any, is most suitable for you. Nutritional needs and health conditions can vary from person to person. And an expert can help you customize a meal plan for intermittent fasting that suits your goals and lifestyle, ensuring that fasting is safe and effective.

Breaking a 36-hour fast as a vegan is a process that should be approached with care and attention to ensure the body readjusts to digesting food smoothly and in a balanced way. This careful approach is advisable for minimizing any gastrointestinal discomfort and maximizing nutrient absorption following the prolonged break in eating.
Here are some important tips to consider, together with a practical example of how you can structure an initial meal to break the fast:
Example of a Meal to Break the Fast:
Pumpkin and Carrot Soup: This smooth, vitamin-rich soup is gentle on the stomach, which makes it a great choice for easing back into solid foods.
Quinoa and Chickpea Salad: For something more filling, try this salad with quinoa, chickpeas, avocado, spinach, and lemon dressing. It offers a balanced mix of protein, healthy fats, and fiber.
Such a meal is suitable for breaking the fast and can also be part of a vegetarian 7-day meal plan for intermittent fasting, helping you maintain a varied and balanced nutrient intake throughout the week.
Always remember to listen to your body and adjust both the portion and type of food according to your personal feelings and digestive needs.
Weight loss is a process that can vary greatly from person to person and isn’t always directly related to the type of diet that’s followed. However, some people who choose a vegan diet tend to experience faster weight loss than those who include animal products in their diet (11). This could be related to several factors:
Reduced Caloric Intake: Plant-based diets often include foods that are naturally lower in calories, such as fruits, vegetables, legumes, and whole grains. This can lead to a lower daily caloric intake, particularly if you’re transitioning from a more omnivorous diet (12).
Increased Fiber Intake: Plant foods are often rich in fiber, which helps increase the feeling of fullness and may contribute to eating less throughout the day (13).
Lower Intake of Saturated Fats: By eliminating animal products, the intake of saturated fats is reduced, which can influence weight loss.
In addition, it’s essential for nutrition professionals to educate individuals who decide to adopt any type of vegetarian diet. They should help them implement it properly to ensure all their necessary macro and micronutrients are covered, according to their age and metabolic state. (14)

As mentioned earlier, intermittent fasting is an eating pattern that alternates periods of fasting with periods of eating. There are several modalities, and some can be more challenging than others depending on the duration of the fast and the restrictions that are involved.

This method involves alternating days of complete fasting (or with very reduced caloric intake) with normal eating days. On fasting days, some people choose to consume only around 500 calories, while others consume nothing at all. The difficulty lies in the frequency of fasting and the need to constantly adapt to drastic changes in caloric intake (15).
Also known as “Eat-Stop-Eat”, this method involves fasting for a full 24 hours once or twice a week. Although it’s not as frequent as alternate-day fasting, the duration of the fast may be a significant challenge for many people (16).
Each person may find a method more or less challenging depending on their lifestyle, nutritional needs, and personal preferences. It’s important to consult a healthcare professional before you start any intermittent fasting regimen, particularly the more strict ones.
At the same time, one of the most commonly used forms of intermittent fasting is the 12-hour fast. This method may be more accessible and easier to follow as it involves fasting for 12 consecutive hours each day, which naturally aligns with many people’s sleep cycles. The 12-hour fast can be an excellent way to start with intermittent fasting, as it’s less restrictive and easier to maintain in the long term (17).
It depends on the type of fasting you’re doing, but generally, during feeding windows, you can consume foods as you normally would, and avocado is an excellent choice due to its nutritional benefits. It is rich in healthy fats, especially monounsaturated fatty acids, which are beneficial for heart health. In addition, avocado contains fiber, vitamins (such as vitamins K, C, E, and several B vitamins), and minerals (such as potassium and magnesium), which makes it a nutritious food that can help maintain satiety during fasting hours (18).
In addition to its nutritional benefits, avocado is an incredibly versatile food that can be incorporated into a variety of recipes.
Eggs are an excellent option for breaking a fast due to their high-quality protein content, which helps satisfy hunger and provides sustained energy (19).
Including eggs at the end of a fast can help stabilize blood sugar levels and offer a sense of fullness, which is useful for avoiding overeating (19). Their versatility also allows them to be prepared in various ways, such as boiled, scrambled, or in omelets, which makes them a practical and nutritious choice.
However, it’s important to consider individual dietary preferences. If you follow a vegan diet, eggs cannot be eaten. However, on a vegetarian diet, eggs are often accepted and consumed, as some vegetarians include products such as eggs and dairy in their diets (20). A vegan alternative is a tofu scramble.
Bananas are a good option to consume after fasting, particularly if you choose greener bananas. These contain resistant starch, which acts like fiber and can help prolong the feeling of fullness and improve digestive health (21).
For additional benefits, it’s advisable to combine the banana with a source of protein and healthy fat, such as nuts. This combination can help stabilize blood sugar levels and provide more sustained energy. For example, nuts provide healthy fats and proteins (22), thereby complementing the nutritional profile of the banana and making the meal more balanced and satisfying.
Adopting a vegan diet may help you lose weight, but weight loss isn’t guaranteed by following this type of diet. The effectiveness will depend on several factors, including the balance between calories consumed and burned and the quality of the foods selected.
As previously mentioned, a well-planned vegan diet that is rich in fruits, vegetables, legumes, and whole grains tends to be lower in calories and saturated fats than diets that include animal products. This can facilitate weight loss, as these foods are typically high in fiber, which increases the feeling of fullness and may help reduce overall food intake throughout the day (23).
However, it’s advisable to avoid highly processed vegan foods or those that are high in added sugars and unhealthy fats as they can contribute to weight gain. It’s also essential to ensure all essential nutrients are covered through a balanced diet.
In conclusion, while a vegan diet can be an effective tool for weight loss, it’s important to maintain a balanced and active lifestyle to achieve optimal results.
Combining intermittent fasting with a vegan lifestyle is a powerful synergy. Especially for those who are looking to optimize their health while respecting ethical and environmental principles. This approach focuses on the timing of food intake and the quality and origin of the foods that are consumed.
By regulating periods of eating and fasting, intermittent fasting can facilitate weight loss. It can improve insulin sensitivity and may promote cellular regeneration. At the same time, by eliminating animal products, veganism fosters a diet that is rich in nutrients. This is because it includes fruits, vegetables, legumes, and whole grains.
To maximize the benefits of this combination, plan adequate intake of essential proteins, vitamins, and minerals. It is also important to listen to your body and adjust practices according to individual needs. Each person may react differently to these dietary changes. Consulting a healthcare professional or registered dietitian can provide personalized guidance. It’s best to make sure that the approach is safe, sustainable, and effective in the long term.
