Intermittent Fasting Defined

Intermittent fasting isn’t a diet so much as a pattern of eating. It is more about when to eat your meals than what you eat, although making healthy food choices for yourself is always recommended.

A vegan intermittent fasting meal plan is an eating schedule, made up of plant-based foods, set up with periods of fasting and then periods of healthy eating.

Intermittent fasting has gained popularity in the health and wellness world and for good reason. It is easy to adopt and offers flexibility, allowing you to select the approach that works for you and aligns easily with your preferences and lifestyle.


Intermittent fasting is a pattern of eating that offers flexibility, and is easy to adopt, which allows you to select the approach that works best for you and your lifestyle.

Methods Of Intermittent Fasting – How I Started

There is no set standard, and there are many ways to do intermittent fasting. The best method is one that you will stick to, and that means exploring the options, and determining what works well with your lifestyle.

For me, I started intermittent fasting years ago, before it even was “a thing.” I was working as a Pediatric Oncology Nurse in the hospital, and living a vegan lifestyle.

I enjoyed preparing plant-based meals for myself and for when I was at work but one day, we were so incredibly busy at the hospital that I simply didn’t eat all day.

Instead of feeling terrible, I actually felt pretty good! Of course, at the end of the day, I was tired but not as tired as one would expect from working a 14-hour day and not eating.

So I began a little experiment with myself, which as a Lifestyle Medicine Nurse, I tend to do. I implemented a liquid fast one day every week. For me, it was every Monday because that was one of the busiest days at the hospital.

In preparation for Monday, I would make myself three large green smoothies, and these were my meals for the day.

Without realizing it I was doing an intermittent fasting plan. My overall health improved, and I felt great.

I had more clarity and energy levels, my bloodwork improved, lost a few pounds, and truthfully could eat as much as I wanted to keep me satisfied on the other days, although I do always try to eat healthfully.


3 Popular Intermittent Fasting Methods

There is no set standard for intermittent fasting. That said, there are a few common methods as to how to incorporate intermittent fasting into your lifestyle.

  1. The 16/8 method: With this method, you have a 16-hour fasting window, and then an 8-hour window to eat. Most people will skip breakfast and then have a restricted eating window range from approximately 12:00 pm – 8:00 pm.
  2. The 5:2 method: This method involves a low-calorie intake, usually 500-600 calories, two days of the week, and then eating normally the other 5 days. The two lower-calorie days should be nonconsecutive.
    • NOTE: Although this method is commonly used, it technically is not an intermittent fasting approach because there are no real fasting periods.
  3. Eat-stop-eat method: With this method, you will incorporate a full 24-hour fasting period one or two days per week.


There are multiple ways to approach intermittent fasting with the 16/8 method being one of the more popular methods due to naturally fasting overnight.

Health Benefits of Intermittent Fasting

Research consistently highlights numerous health benefits of intermittent fasting, and while ongoing studies expand our understanding, here are some well-documented advantages to date (1) (2).

  • Diabetes (type 2) and obesity – helps with weight loss, and improves insulin resistance and blood sugar levels.
  • Cardiovascular disease – helps with heart disease such as lowering cholesterol levels, improving blood pressure, and resting heart rate.
  • Brain function – improves cognitive function such as clarity, thinking, and memory
  • Tissue health – reduces tissue damage and repair after surgery
  • Neurodegenerative disorders – protects against neurodegenerative disorders due to age.
  • Inflammatory bowel disease – protects against bowel disease
  • Cancer – protects against many types of cancer
  • Inflammatory conditions – improve conditions associated with inflammation, such as arthritis, asthma, Alzheimer’s disease, multiple sclerosis, and stroke


Intermittent fasting provides numerous health benefits, and is protective against chronic conditions that are due to inflammation.

The Science Behind Intermittent Fasting: What happens in our body

Science shows that when we do intermittent fasting, there are metabolic changes that happen within our bodies.

During regular feeding times, we use glucose as our primary energy source throughout the day. However, in a fasted state, when we fast for prolonged periods, we begin to burn fat for energy. This is known as “metabolic switching” (3).

When our bodies are using glucose for fuel, insulin is the main hormone being used but when we are fasting, glucagon is the primary hormone, and our bodies use glycogen that has been stored in the liver for energy (3).

Metabolic switching begins right when the glycogen stores have been depleted and our body begins to metabolize fat for energy, which usually occurs after approximately 12 hours of fasting.

This process, burning fat for fuel, prevents the breakdown of muscle mass and its function and is thought to improve body composition in overweight individuals (3).

By practicing intermittent fasting, and reaching metabolic switching, we improve metabolism and increase our health and longevity (3).


Prolonged periods of fasting allows our body to switch from burning glucose to burning fat for energy. This is known as “metabolic switching,” which improves health and longevity.


Veganism Defined

The word vegan was invented by Watson and Dorothy Morgan, and is based on “the first three and last two letters of ‘vegetarian’ (4).”

Veganism is defined as “the practice of abstaining from the use of animal products – particularly in the diet – and an associated philosophy that rejects the commodity status of animals. A person who follows the diet or philosophy is known as a vegan (4).”

Individuals adopt veganism for a variety of reasons, and there are distinct categories to differentiate these perspectives.

  • Dietary vegans – also known as “strict vegetarians” do not eat any animal products, including meat, eggs, and dairy.
  • Ethical vegans – ethical vegans are dietary vegans but also do not use any animal products or animal-tested products (For example: leather goods).
  • Environmental vegans – these vegans avoid animal products based on concern for animal welfare, and believing that industrial farming of animals is environmentally damaging.


Veganism is the practice of abstaining from animal products, however there are different categories of veganism depending on an individuals principles and philisophical beliefs.

Health Benefits Of A Vegan Lifestyle

Embracing a whole food plant-based diet, or dietary vegan lifestyle, has demonstrated multiple health and longevity benefits both physical and mental. Here are some of the benefits (5).

Physical Benefits

  • improve weight management and metabolism
  • reduce cholesterol
  • reduce blood pressure
  • reduced risk of chronic disease due to inflammation

Emotional Benefits

  • decrease anxiety
  • decrease depression
  • decrease fatigue
  • improved overall sense of well-being
  • improved daily function

Combining Intermittent Fasting And Veganism

While specific studies on the combined effects of intermittent fasting and veganism are lacking, and further research is needed, there is a potential synergistic effect when integrating both practices.

Some of the potential benefits of an intermittent fasting vegan meal plan are enhanced metabolic flexibility including the reduction of body fat, improved insulin sensitivity, improved brain functioning, improved heart health, reduced cancer risk, and potential anti-aging benefits.


While specific studies linking intermittent fasting and veganism are lacking, and further research is needed, combining both practices may yield a synergistic effect.

Organizing Your Intermittent Fasting Vegan Meal Plan

When planning your intermittent fasting vegan meal plan, it is important to consider macronutrient factors to create well-balanced meals that support your nutritional needs and enhance the benefits of both intermittent fasting and a vegan diet.

Balanced Macronutrient Ratios: It is important to avoid junk food, and ensure a well-balanced distribution of proteins, carbohydrates, and fats, as every macronutrient plays a vital role in supporting overall health.

Protein Sources: There are a variety of plant-based proteins to choose from to meet your body’s requirements such as beans, legumes, nuts, seeds, tofu, and tempeh.

Carbohydrate Sources: It is important to choose complex carbohydrates and high-fiber foods such as leafy greens, fruits, vegetables, and whole grains. Versus refined sugars and processed carbs such as bread, pasta, cereals, and cookies.

Fat Sources: Incorporating healthy fats into your diet is important for satiety and avoiding hunger pangs, as well as brain health and nutrient absorption. Healthy fats to consider are nuts, seeds, avocado, and olive oil.

Just as important in the design of an intermittent fasting vegan meal plan are the micronutrients to consider.

Make sure your meal plan has a variety of nutrient-dense whole foods to ensure you are meeting proper vitamin and mineral requirements. This involves eating a colorful array of fruits and vegetables in your meals.


Hydration Is Crucial When Fasting

It is important to stay well-hydrated during periods of fasting. Water is essential for overall health but it is especially important when fasting.

Staying well-hydrated not only aids in suppressing hunger during fasting but it also facilitates the elimination of any unwanted cellular debris and breakdown from the body.

Staying hydrated will help maintain energy levels, and it will reduce any potential side effects of fasting like headaches, fatigue, and irritability (6).

Drinking plenty of water is always a good choice but there are other drinks you may also want to consider while intermittent fasting.

  • Black coffee – hot or iced
  • Black tea – hot or iced
  • Herbal tea – hot or iced
  • Seltzer water – without added sugar
  • Flavored water – with a tablespoon or so of orange, lime, or lemon juice
  • Apple cider vinegar – 1 to 2 tablespoons in 8 to 10 ounces of water. Some feel this helps curb their appetite while fasting
    • NOTE: If you do drink apple cider vinegar diluted in water regularly, you may want to consider using a straw to keep the vinegar off of the enamel of your teeth to prevent tooth decay.

These beverages are safe to consume during the fasting state and will not spike your blood sugar.

Make sure to avoid adding milk, cream, or sugar to any of these drinks, as it can significantly raise your blood sugar and insulin levels.


When creating your intermittent fasting vegan meal plan, aim for a balanced mix of protein, carbohydrates, and fats, along with colorful, nutrient-rich foods. It is also importnat to stay well-hydrated during fasting.

5 Top Tips For Success

Here are five helpful suggestions to set you up for success when designing an intermittent fasting vegan meal plan.

1. Gradual Transition

Embarking on a whole food plant-based diet and intermittent fasting simultaneously can be overwhelming, especially for beginners. It may be more manageable to adopt one eating style first, master it, and then gradually integrate the other.

2. Monitor Nutritional Intake

Effective meal planning is important when combining a vegan diet and intermittent fasting. Consuming fewer calories necessitates a focus on obtaining sufficient high-quality nutrients and vitamins.

3. Meal Variety

A great way to ensure you are eating a healthy diet is to incorporate a diverse range of foods into your own meal plan. This approach helps to ensure you are getting the most fiber and nutrients out of each meal.

4. Hydrate

Drinking plenty of water prevents you from getting dehydrated, and helps you feel full longer. The best way to ensure you are drinking plenty is to carry a water bottle with you throughout the day.

5. Listen To Your Body

Listening to your body, and all of its signs and symptoms is important when you are embarking on a dietary lifestyle change. Intermittent fasting is not a fad diet, nor is veganism, and paying attention to how your body responds to both is important and necessary.


It is important to set yourself up for success when designing an intermittent fasting vegan meal plan. Ease into fasting if you are new to it, eat high quality nutrient-dense food, mix up the type of foods you eat for variety, drink plenty of water, and listen to your body.

Is Intermittent Fasting With Veganism Safe?

Practicing intermittent fasting along with veganism is done for a variety of reasons. Some people use it as a weight loss method or for weight management, while others choose to do intermittent fasting and veganism for health and longevity.

It is important to talk to your primary healthcare professional before trying intermittent fasting, or any change in your diet and physical activity for that matter.

Intermittent fasting in particular is not for everyone and should be avoided for people with certain conditions.

  • Diabetes – type I, and even type II if they are having a difficult time maintaining stable blood sugar levels.
  • Kidney disease
  • Children
  • Pregnant women
  • Breastfeeding
  • Thyroid disorders
  • Underweight
  • History of an eating disorder


Intermittent fasting and veganism are not for everyone and it is important to talk to your medical healthcare professional before embarking on any new diet or lifestyle activity.
