The ketogenic diet is a high-fat, low-carbohydrate diet that forces the body to burn fats rather than carbohydrates for energy. This produces ketones as a byproduct and offers numerous benefits for weight loss, diabetes management, and overall health.
Antibiotics can affect the ketogenic diet by disrupting the balance of bacteria in your gut, affecting your ability to digest and absorb nutrients from food. Some antibiotics can also interfere with the metabolism of nutrients, such as carbohydrates, affecting your ability to stay in ketosis.
In this article, we will explain how antibiotics affect the ketogenic diet, what you can do about it if you’re on the diet, and what you should avoid until your microbiome has recovered from antibiotic treatment.

What Is a Ketogenic Diet?
A ketogenic diet is a high-fat, low-carbohydrate diet. On a ketogenic diet, your body produces ketones as a byproduct of burning fat instead of glucose, which is the main source of energy for the body when carbohydrates are not available.
Ketogenic diets have been used to treat epilepsy in children since the 1920s. In the past decade, it has become a popular diet for weight loss, diabetes management, and overall health.
A ketogenic diet can be beneficial for people with type 2 diabetes, metabolic syndrome, neurological disorders, and various kinds of cancers.
How Do Antibiotics Affect the Ketogenic Diet?
A ketogenic diet relies on your gut microbiome for the production of vitamin K2 and vitamin B12, which are necessary for maintaining proper blood sugar levels and energy metabolism. Bacteria in the gut help produce these vitamins in the intestines by metabolizing the nutrients in food.
But antibiotics kill the beneficial bacteria in your gut, which means that you will have no way to get these important nutrients. The lack of vitamin K2 can lead to a condition called “nutritional osteopenia” in which the bones are weak and brittle.
Vitamin K2 is necessary for the proper mineralization of bone tissue. Vitamin B12 deficiency can lead to anemia, fatigue, mood disorders, and nerve damage.
Antibiotics are a group of medications that can be used to fight off infections. However, they can also have an impact on the body’s ability to function properly. For example, they can change the makeup of the gut microbiome and alter the way that the body produces energy.
An imbalance in gut bacteria can lead to symptoms like bloating, digestive issues, and constipation.
If you take antibiotics while you’re on a ketogenic diet, they could disrupt your body’s ability to produce ketones. In addition, they could cause nutrient deficiencies and encourage the growth of unfriendly bacteria.
Antibiotics should be used with caution if you’re trying to lose weight or maintain a healthy lifestyle.
Problems With the Ketogenic Diet When Taking Antibiotics
When you take antibiotics, they kill the bacteria in your body that is causing the infection, as well as other bacteria throughout the body. This includes the bacteria in your gut that break down food into vitamins and minerals that you need for energy.
Antibiotics also destroy the “good” bacteria in your gut that helps with digestion. This has the potential to disrupt the process of ketosis, leading to several unwanted side effects.
Without enough good bacteria to process food properly, you may experience digestive issues, such as bloating, gas, and diarrhea. This can lead to a lack of appetite and make it difficult to digest the nutrients in your food.
When your body doesn’t have enough nutrients from food, it will break down muscle tissue and use it to supply the nutrients needed for daily functions. This process is called catabolism, which is the opposite of anabolism, or building up the body with nutrients.
When the body is in the state of catabolism, it can’t be in the state of ketosis.
Can Antibiotics Kick You out of Ketosis?
In short, antibiotics can potentially kick you out of ketosis if you’re not careful. When your body is in ketosis, it uses fat for energy instead of glucose, which makes the conversion of protein to energy very efficient. This means that any type of antibiotic could theoretically disrupt this process and lead to nutritional deficiencies.
If you’re taking an oral antibiotic as a treatment plan, it’s important to speak with your doctor about how long the medication should be taken and when it can be stopped. Similarly, if you are receiving intravenous antibiotics (such as those used on hospitalized patients), make sure to inform your doctor so that they will know when discontinuing the treatment is necessary.
In most cases, stopping antibiotics at appropriate intervals will ensure complete recovery without any adverse effects associated with ketosis withdrawal syndrome.
How to Stay in Ketosis After Taking Antibiotics
The best way to stay in ketosis after taking antibiotics is to limit your intake of carbohydrates. The standard ketogenic diet recommends a daily intake of 20 grams of carbohydrates, but when you’re recovering from antibiotics, this number should be lower.
You can also consider taking probiotics to restore the bacteria in your gut after taking antibiotics. Although the research is inconclusive, some studies suggest that probiotic supplementation may help restore the bacteria in the gut after taking antibiotics.
If you’re worried about losing your ketogenic diet progress, consider keeping a food diary. This will give you better insight into what you’re eating and how you’re feeling as you recover from taking antibiotics.
Takeaway
The ketogenic diet is a low-carb, high-fat diet that puts the body into a state called ketosis. Ketosis is a metabolic state that occurs when the body doesn’t have enough glucose for energy, so it burns fat for fuel instead. This diet is extremely effective for weight loss, diabetes management, and overall health.
When you take antibiotics, they kill the bacteria in your body that is causing the infection, as well as other bacteria throughout the body. This includes the bacteria in your gut that break down food into vitamins and minerals that you need for energy.
Antibiotics also destroy the “good” bacteria in your gut that helps with digestion. This can cause digestive issues, a lack of appetite, and difficulty absorbing nutrients from food.

If you’re on the ketogenic diet and need to take antibiotics, try to keep your carbohydrate intake low. You can also consider taking probiotics to restore the bacteria in your gut after taking antibiotics.
By following the advice in this article, you can keep the benefits of the ketogenic diet while taking antibiotics.
Frequently Asked Questions
Can I take probiotics while on the ketogenic diet?
Yes, probiotics are beneficial when it comes to balancing gut health. However, make sure that your probiotic supplement doesn’t contain any high-carb ingredients such as grains, seeds, or fruit powders because they may kick you out of ketosis. You should also avoid any probiotic supplements that contain Vitamin K2 because they are high in fat and will kick you out of ketosis as well.
Are ketogenic diets good for you if you’re taking antibiotics?
Taking antibiotics can lead to temporary changes in your gut bacteria that may make it harder for you to absorb nutrients from food. This is why eating a balanced diet and taking probiotics can be important if you’re on antibiotics. If you’re concerned about potential side effects, talk to your doctor before starting a ketogenic diet.
Can I take a fiber supplement while on the ketogenic diet?
Yes, but you should make sure that it is a zero-carb fiber supplement and not one that contains any high-carb ingredients such as grains, seeds, or fruit powders because they may kick you out of ketosis. You should also avoid any fiber supplements that contain Vitamin K2 because they are high in fat and will kick you out of ketosis as well.
Can I take digestive enzymes while on the ketogenic diet?
Yes, but only if they don’t contain any high-carb ingredients such as grains, seeds or fruit powders because they may kick you out of ketosis. You should also avoid any digestive enzyme supplements that contain Vitamin K2 because they are high in fat and will kick you out of ketosis as well.
What if I have a medical condition where I need to take antibiotics?
What if I have a medical condition where I need to take antibiotics?
If you have a medical condition that requires taking antibiotics, such as a severe infection or an allergy, then you should consult with your doctor before starting the ketogenic diet. If your doctor says that taking antibiotics while on the ketogenic diet is safe for you, then start by following the instructions in this article and eating a low-carbohydrate meal like chicken or fish with vegetables cooked in olive oil.
