What Is Fat Fasting?
Fat fasting refers to consuming high amounts of fat while limiting protein and carbohydrates to burn fat and reach special health goals.
Fat fasting is mainly used by those on a Carnivore, ketogenic or low-carb diet to enter ketosis or weight loss faster.
Why is fat fasting practised by many? Because by consuming large amounts of healthy fats, the body will burn fat for fuel instead of glucose from carbohydrates, which will result in faster fat melting and other health improvements like better blood sugar control and reduced inflammation.
Many Carnivore dieters try a type of fasting during their diet to boost their fitness and health results. The above video tells you all about fat fasting on a Carnivore method.
The first time I heard about fat fasting and its effects on losing fat, I wondered how eating fat results in losing fat. How does it make sense? The next section will tell us what I found.
Does Eating Fat Result in Losing Fat? How?
The short answer is yes; eating fat will result in losing fat. But how? Fat fasting speeds up fat loss by putting your body in a state of ketosis, which burns fat for fuel instead of glucose from carbohydrates.
When you limit the intake of carbs and protein and consume healthy fats, your body is forced to use stored fat as its primary source of energy, and that’s how you lose fat!
But that’s not all, as fat fasting also reduces insulin levels, which further increases fat burning. Insulin hormone is released as a response to carbohydrate intake and promotes the storage of glucose as fat.
By consuming low levels of carbs and protein during a fat fast, insulin level remains low, so it prevents excess fat storage.
The question that may arise here is that there is one type of fat fasting, and if I follow that one method, I’ll lose fat. Let’s see if fat fasting can be done in different ways.

Fat fasting comes in different types, but all of them are based on consuming fat and fatty foods for a short time. Here are some of the most popular types of fat fasting.
Traditional Fat Fast: It refers to consuming about 1,000 calories daily, 90% of which comes from fat. The intake of protein and carbs are limited, and meals include fatty foods like butter, cheese, ghee, egg, beef, etc.
Modified Fat Fast: This version includes consuming about 1,200-1,500 calories a day, 70-80% of which comes from fat and fatty foods.
Bone Broth Fast: This type of fat fasting includes consuming bone broth and fatty mini meals.
There may be other versions of fat fasting available, as this type of fasting is so versatile, and dieters can customise it to their liking. Anyhow, the most important point is to keep the meals small and fatty.
Remember that fat fasting can be done no matter what diet you’re on. You can try this simple and fast fat-loss method anytime, but it’s most common with Carnivore dieters. Let’s learn a bit more about Carnivore fat fasting.
What Is Carnivore Fat Fasting?
Carnivore fat fasting refers to consuming only animal-based foods like meat, fish, eggs, and dairy. As its name suggests, it is often used by Carnivore dieters.
The main difference between Carnivore fat fasting with any other fat fasting method is that in this type of fasting, you need to consume Carnivore-friendly foods.
It means you’re not allowed to eat vegetables or plant-based foods and must rely on animal products, from ruminants to poultry and seafood.
The main objective of a Carnivore fat fast is to consume high amounts of healthy fats, including beef tallow, lard, butter, and fatty foods, while keeping protein intake moderate and removing carbs to promote ketosis and rapid weight loss.
Similar to other types of fat fasting, Carnivore fat fasting is short and during which you need to eat small, high-fat meals throughout the day.
You may think that Carnivore fat fasting means eating only cuts of butter, but NO! Opposite to what many may think, Carnivore fat fasting includes super yummy foods, from fatty cuts of beef, salmon, bacon, eggs cooked in butter to lard, and high-fat dairy products like heavy cream and cheese.
I know many other questions are popping up in your mind, but don’t worry! I’ll answer all your questions in this article. So keep calm and scroll down to learn about fat fasting rules and other details.

Better Metabolism: Fat fasting reduces inflammation, improves insulin sensitivity, and promotes lipid profiles, resulting in better metabolism.
Better Cognitive Function: Some studies show that fat fasting can improve cognitive function in some people and protect against diseases like Alzheimer's.
Weight Loss Kickstart: Fat fasting can work as a kickstart to fat loss for those facing a halt in their weight loss process.

It can also be beneficial for
individuals with insulin resistance,

A 3-day fat fast is one of the most common fat fasting periods, which takes only three days and includes consuming large amounts of fat and limiting protein and carbohydrate intake.
The following subsections break down the meal plans you need to follow for a 3-day Carnivore fat fasting program.
What Is a 3-Day Fat Fast?
Although a 3-day fat fast can include different foods for different individuals, a typical 3-day fat fast can include 3-4 small meals daily.
Each meal can contain fat sources, such as butter, cream, cheese, and fatty meats. Carbohydrates like fruits, vegetables, and grains must be avoided or limited. Here are the foods you can eat every day on fat fasting.
Between the meals you can have mini meals containing butter and other Carnivore-friendly foods.
Although we’ve mentioned the benefits of Carnivore fat fasting and its positive effects on weight loss, it can have some side effects on some individuals. Let’s learn about them to avoid them in advance.
Side Effects of Fat Fasting
Hunger: although fat is really filling, some may experience feelings of hunger and low energy levels because of being low calorie.
Nutrient Deficiencies: Some say fat fasting may cause nutrient deficiencies as it solely focuses on consuming fat. However, it’s highly unlikely as fat fasting is only for some days and a long term.
Digestive Issues: Some may experience digestive problems such as diarrhea, constipation, and bloating on fat fasting.
Bad Breath: Ketones produced during fat fasting can cause bad breath.
Headaches: Some individuals may face headaches during fat fasting when the body tries to adapt s to the low-carbohydrate diet.
Muscle Loss: Some say fat fasting can cause muscle loss as you consume low amounts of protein. But again, it’s not likely, as fat fasting only takes some days.
If you’re a bit afraid of the side effects or wish to start fat burning in a logical and healthy way, the next section is yours!
To understand the real results of fat fasting, check out the following video showing how I tried a 3-day fat fasting with significant results.
Does a Fat Fast Induce Autophagy?
Autophagy is a body process to clean damaged cells and debris and recycle them for energy. Some research shows that fat fasting may have a positive impact on autophagy.
During fat fasting and the ketosis process resulting from it, autophagy can be activated. Ketosis stimulates the release of the glucagon hormone, which boosts the breakdown of stored glycogen and fat for energy.
This process can increase autophagy, as the body employs its own damaged cells and proteins for fuel, but further research is needed to support the impact of fat fasting on autophagy.
Fat Fasting vs Water Fasting
Fat fasting refers to consuming fat and low levels of carbohydrates and protein to create a state of ketosis for the body to burn fat for fuel instead of glucose.
However, water fasting is a restricted version of intermittent fasting, which includes the consumption of only water and no food for a certain period.
Water fasting can last for 24-72 hours but is generally more challenging to adhere to than fat fasting.
Both fat fasting and water fasting have been shown to have effective for weight loss, insulin sensitivity, and reduced inflammation, but choosing among them depends on your personal goals, preferences, and health considerations.
Generally, fat fasting is more sustainable and easier to follow, while water fasting is more extreme but may lead to faster results if you can follow it.
All in all, fat fasting has proven to promote weight loss and other health benefits. Fat fasting combined with proper meal plans can result in significant health effects.
However, consulting a healthcare professional is necessary before making drastic changes to your eating habits. Also, remember that fat fasting is a short-term process.
With logical Carnivore fat-fasting planning and sticking to that plan, you can achieve your weight loss goals and experience other health benefits. Click to learn more about Carnivore diet courses for fat loss.
