Maintaining a healthy body weight is one of the best ways to support your overall health. Excess body fat increases your susceptibility to serious conditions like type II diabetes, high blood pressure, stroke, heart disease, sleep apnea, fatty liver, cancer, and joint concerns. Many fat-loss fads, diets, and pills come and go, and very few yield lasting results. Adopting a ketogenic diet is one strategy for losing fat that’s tried, tested, and proven effective.
Knowing this, I began my research into improving the typical ketogenic diet. People who are familiar with my work know that I’m always trying new cleanses, detox programs, and diet plans in my ongoing quest to discover new ways to improve my health. I kept coming across the many benefits of fasting, and I thought, “Why not combine principles of fasting with the best elements of a ketogenic diet and enjoy the best of both?”
What Is a Ketogenic Diet?
A ketogenic diet is a diet that provides fat and protein, but few or no carbohydrates. The body prefers glucose and glycogen, both derived from carbohydrates, as its primary source of fuel and it generally operates in a sugar-burning state known as glycolysis. Depriving the body of carbohydrates, however, forces it to use stored fat for energy. This special fat-burning mode, known as ketosis, quickly burns through fat reserves. It takes about 24-36 hours to completely burn through the glycogen stored in the muscles and liver. The catch? The body tells the brain to refuel on carbohydrates when blood sugar dips. In other words, your appetite kicks in and you feel hungry. This physiological response makes it a challenge for many people to adhere to a ketogenic diet long enough to enter ketosis.
What Is Fasting?
Fasting means avoiding food for longer periods than usual, generally 12 or more hours. You may do this inadvertently if you ever skip breakfast or can’t fit lunch into your schedule. Fasting may support a healthy metabolism, encourage stable blood sugar, promote normal blood sugar, and offer other benefits for overall wellness. There are many ways to fast. True, or absolute, fasting means completely abstaining from eating and drinking for a set period. Water or juice fasting allows for the consumption of certain fluids during the fast. Some people have the misconception that fasting is total starvation, but fasting is not starving — it’s simply committing to eating in accordance with a more regimented schedule.
Dr. Group’s Ketogenic Fast: The Best of Both
Both fasting and following a ketogenic diet prompt the breakdown of fat and encourage the body to detoxify itself. Many of the worst toxins are stored in fat cells. When the body burns through fat reserves, toxins are released and expelled. And, not only does a ketogenic fast encourage the body to enter fat-burning mode, it discourages the body from storing new fat. This understanding prompted me to combine principles of fasting with a ketogenic diet to develop my 5-day, vegan ketogenic fast.
Many ketogenic diets advocate the consumption of animal-based fat and protein. But, that sort of diet increases your risk of kidney stones, cancer, and cardiovascular disease.[3, 4] Conversely, a low-carb, plant-based diet is incredibly beneficial for overall health and wellness. I constructed this ketogenic diet to be vegan and based it around nuts and fatty fruits like olives, coconut, and avocados — all of which provide fatty acids, fiber, micronutrients, and phytonutrients.
A ketogenic diet can boost overall wellness. Studies have found that people who follow a ketogenic diet experience better, more stable moods. Some individuals report feeling profoundly happy, peaceful, and at ease. There's also evidence to suggest that fasting promotes good physical health at the cellular level.[7, 8]
The following is an account of my personal experience with the 5-day, vegan ketogenic fast.
I began the day around 6:30 AM with 1 ounce of nuts and my standard supplement routine. Around noon, I had one tablespoon of coconut oil for lunch. Between 2-3 PM, I felt hunger pangs, which I expected. At that point, my body was still running on glycogen stores and telling me to eat carbohydrates. For dinner, I ate an avocado and six olives.

Length: 3 minutes
When I awoke, I weighed myself and was astounded to discover I was nearly 9 pounds lighter! I know this was mostly water weight, but it’s remarkable to see such an incredible drop in just 24 hours. Overall, I felt more energetic than I did yesterday, and I was decidedly less hungry than day 1. My morning workout was great — I felt like I had the energy to continue for another hour.
I kept the same diet schedule as day 1. I was still hungry after the tablespoon of coconut oil for lunch, but the sensation was less intense. I had some water with a shot of apple cider vinegar to ease the hunger pangs. Later in the evening, I tried my first ketone test strip, and I was indeed in ketosis — the fat-burning state.

Length: 3 minutes
This was my worst morning yet. My morning workout did not go as well as I hoped. I felt disoriented and disconnected. I noticed my thinking wasn’t as clear or sharp as normal. I stuck with the same diet; I didn’t experience any hunger, but I did feel somewhat shaky.
I felt better as the day went on. I experienced minor hunger pangs around 2:30 PM that lingered until dinner. As evening approached, I found myself in a much better state and mood.

Length: 3 minutes
The morning of day 4 was like waking up from a dream. I felt incredibly energized and alert. The brain fog and weakness from day 3 was entirely gone. The real breakthrough was the mental clarity. So many people experience this incredible effect, and its reason enough to try fasting. I felt focused and optimistic. The ketone test strip revealed I was still in fat-burning mode and my noticeably looser pants confirmed it.
I didn’t experience any hunger, but I switched up the diet and had avocado and olives for lunch. It felt like the right decision. My body needed the larger meal to remain sustained through the rest of the workday.

I felt even better on day 5. My energy levels were high and I didn’t experience any hunger pangs. My mood was elevated and my mind was focused. I felt like I could sustain this diet for longer.

Getting Started with Dr. Group’s 5-Day Vegan Ketogenic Fast
It’s easy to get started with my 5-day, vegan ketogenic fast. It requires just a few supplies. First, you need ketone test strips. Ketone test strips are dipped into urine to measure how many millimoles of ketones are present (which will require you to catch your urine in a cup). They are readily available online and they're easy to use. The average reading should be about 4-6 millimoles (mM), but you may see readings as high as 8 mM. If they're color-coded, and most are, darker readings indicate you’re burning more fat. You’ll need enough strips to test your urine twice a day for the duration of the fast.
You’ll also need the nuts described in the diet below. I recommend dividing them into 1-ounce servings before beginning to remove the guesswork and reduce temptation. For the olives, I recommend whole (not pitted) kalamata olives because they’re brimming with antioxidants. Make sure everything is organic and minimally processed.
- 2 Ketone Test Strips
- Pecans: 1 ounce (about 19 halves) = 196 calories
- Walnuts: 1 ounce (14 halves) = 184 calories
- Macadamia Nuts: 1 ounce (12 kernels) = 204 calories
- Pine Nuts: 1 ounce (about 167 kernels) = 191 calories
- 6 Organic Non-pitted Olives = 24 calories
- Organic Medium Avocado = 322 calories
- Organic Raw Coconut Oil: 1 tablespoon = 120 calories
- Average Daily Calorie Intake = 700-1240 calories
Dr. Group’s 5-Day Vegan Ketogenic Fast Daily Protocol
I’ve outlined the basic diet plan below but you can adjust the meal order to suit your needs, just as I did during my fast. One hard and fast rule, however, is that you’ll only eat over the course of 12 hours. I recommend starting at 6 AM and finishing your last meal around 6 PM. Use a ketone strip when you first wake up and just before you go to bed.
1 ounce of nuts, either a mix or just one kind
6 Organic Non-pitted Olives: 24 calories 1 Organic Medium Avocado: 322 calories
1 Tablespoon Organic Raw Coconut Oil: 120 calories
Water with Apple Cider Vinegar Kombucha (low sugar) Herbal Tea Black Coffee
Supplements of Your Choice
Even though you’re not consuming a lot of food, a half serving of Oxy-Powder® every other day will support the detoxification process.

Tips & Things To Know
The trick is sticking to it long enough to reap the benefits. Most people find it extremely difficult to fast for extended periods, so I included enough food to make this plan accessible to more people.
It’s a strict diet, and you must follow it to the letter to achieve your weight loss goals.
Only those who are overweight by 15 lbs or more should adopt this fast. It’s not intended for children, people with type 1 diabetes, or breastfeeding or pregnant women. Always consult your trusted healthcare professional before starting a new diet.
If you feel your energy lagging, take vitamin B12 for a boost. I also recommend drinking plenty of water and taking 1-2 capsules of Oxy-Powder every other day while on the fast to help flush your system.
To settle a sour stomach, drink 8 ounces of water with apple cider vinegar. If it doesn’t help, drink 4 oz of unsweetened organic almond milk.
Continuing to fast after five days can produce varied results. For some, they feel incredible and continue on an upward trend toward euphoria. Others feel a strong desire to break the fast. Listen to your body. If your body is telling you to stop fasting, stop.
For regular maintenance, perform this fast a few times a year.
Maintaining Your Progress
One of best ways to maintain your progress is to cultivate a healthy microbiome. Health begins in the gut, and a chaotic microbiome that doesn’t work with you works against you. The overall shift toward a carb-heavy, fiber-deprived diet has fundamentally altered the microbiome of most people. An investigation into the microbiome of obese individuals revealed that they have less microbial diversity in their microbiota. Bad gut bacteria repress fast-induced adipose factor (FIAF), an essential protein that regulates the use of fat stores, while fiber-loving bacteria upregulate FIAF.[8, 9]
Don’t switch back to a carb-heavy diet immediately after your fast ends. If you make it to at least day 5, you shouldn’t feel this impulse, but if you do, resist it. Gently adjust your macronutrient ratios, reduce yourself from a high-fat, moderate-protein, low-carb diet to one that's healthy and easy to maintain.
Does Fasting Cause Muscle Loss?
Glycogen is stored in the muscles so depleting glycogen reserves can cause muscles to appear smaller. However, while some muscle may be lost during a low-calorie diet, it should be a negligible amount (especially compared to the fat loss). This diet, even though it's a vegan diet, it provides all nine essential amino acids to support muscle mass maintenance. Regardless, the human body needs a lot less protein than most protein powder manufacturers and fitness websites would have you believe. Not only do most Americans eat several times the amount of protein that they need, most of the protein the body needs is dedicated to enzymatic activity, not the maintenance of muscle mass.
