The ketogenic diet is a popular weight-loss diet that involves eating a low amount of carbohydrates, a high amount of fat, and a moderate amount of protein. While the diet is considered safe for most people, it is associated with some unpleasant side effects, such as the keto flu. The keto flu is a collection of symptoms that some people experience when they first start the keto diet, including nausea, constipation, headaches, fatigue, and sugar cravings. These symptoms are caused by the body's withdrawal from carbohydrates and can last from a few days to several weeks. In extreme cases, the keto flu can last up to a month. However, it's important to note that not everyone will experience the keto flu, as some people are naturally metabolically flexible. To reduce the symptoms of the keto flu, it is recommended to stay hydrated, replace lost electrolytes, get enough rest, and ensure adequate consumption of fats and carbohydrates.

The keto flu is a collection of symptoms experienced by some people when they first start the keto diet
The keto diet is very low in carbohydrates, high in fat, and moderate in protein. This drastic reduction in carbohydrates can come as a shock to the body and may cause withdrawal-like symptoms, similar to those experienced when weaning off an addictive substance like caffeine. The body burns carbohydrates (glucose) for energy by default, so switching to a fat-burning process can confuse your body.
Some of the most frequently reported symptoms of the keto flu include:
- Stomach aches or pains
- Nausea
- Dizziness
- Sugar cravings
- Cramping
- Muscle soreness
- Irritability
- Diarrhea or constipation
- Trouble falling asleep or staying asleep
- Poor focus and concentration
- Brain fog
- Headache
- Fatigue
Symptoms of the keto flu generally begin within the first day or two of removing carbs. For most people, the keto flu can last a week or less, but in extreme cases, it can last up to a month. However, depending on your genetics, you may never experience the keto flu.
- Ease into the keto diet gradually, instead of going "cold turkey." Start with a typical low-carb diet and give your body time to adjust.
- Stay hydrated by drinking plenty of water.
- Take an electrolyte supplement to add plenty of electrolytes like salts, potassium, and magnesium to your diet.
- Ensure you're consuming enough healthy fats.
- Get plenty of rest.
- Try light exercise, such as restorative yoga, to help relieve muscle pain and tension.

Symptoms of the keto flu can include: stomach or intestinal pain, nausea, dizziness, sugar cravings, cramping, muscle soreness, irritability, and trouble sleeping
Stomach or intestinal pain, nausea, dizziness, sugar cravings, cramping, muscle soreness, irritability, and trouble sleeping are all symptoms of the keto flu. This is a collection of symptoms experienced by some people when they start a ketogenic diet.
The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein. Reducing your carb intake forces your body to burn ketones for energy instead of glucose. This switch to burning fat for energy is called ketosis. Ketosis occurs during starvation and fasting, and can also be reached by adopting a very low-carb diet.
The keto flu is essentially the body's response to entering ketosis. The symptoms of the keto flu can include:
- Stomach or intestinal pain
- Nausea
- Dizziness
- Sugar cravings
- Cramping
- Muscle soreness
- Irritability
- Trouble sleeping
These symptoms can range from mild to severe and vary from person to person. They typically last a few days or up to several weeks, but in some cases, they can last up to a month.
If you are experiencing these symptoms, it is important to stay hydrated, replace lost electrolytes, get enough rest, and ensure you are consuming enough fat and carbohydrates. Light exercise, such as yoga or leisurely biking, may also help improve symptoms.

The keto flu can last from a few days to several weeks, and in extreme cases, up to a month
The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. It is caused by the body adapting to a new diet consisting of very few carbohydrates. Symptoms of keto flu include stomach or intestinal pain, nausea, dizziness, sugar cravings, cramping, muscle soreness, irritability, diarrhoea or constipation, trouble falling asleep or staying asleep, poor focus and concentration, and brain fog.
The duration of the keto flu depends on various factors, including how metabolically flexible the person was before starting the diet, how insulin-sensitive they are, and the number of carbs they were consuming before. It is important to remember that everyone's body deals with the keto diet differently, and some people may never experience the keto flu at all.
To manage keto flu symptoms, it is recommended to ease into the diet gradually, stay hydrated, replace lost electrolytes, get plenty of rest, and avoid strenuous activities.

Ease into the Diet Gradually
The keto flu is your body's response to a sudden and drastic reduction in carbohydrate intake, which can be mitigated by easing into the ketogenic diet. Start with a typical low-carb diet and give your body time to adjust before fully transitioning to keto. This approach can help reduce the intensity of keto flu symptoms.
Stay Hydrated
The keto diet can cause a rapid loss of water stores, leading to dehydration. Drinking plenty of water is crucial to prevent dehydration and alleviate symptoms such as fatigue and muscle cramping. Set reminders or keep a glass of water within reach to ensure you're drinking enough throughout the day.
Replace Lost Electrolytes
The keto diet often results in a decrease in insulin levels, which can lead to the loss of electrolytes like sodium, potassium, and magnesium. Include more salt in your diet, drink sports drinks high in electrolytes, or consider taking electrolyte supplements. This can help address symptoms such as cramps, nausea, fatigue, muscle cramps, and body weakness.
Get Plenty of Rest
Keto flu can be exhausting, so make sure to get plenty of rest. Take Epsom salt baths to soothe and relax your muscles, and improve electrolyte absorption. Drink herbal tea with calming herbs like chamomile to promote better sleep.
Eat Enough Healthy Fats
Ensure you're consuming enough healthy fats, such as avocado, bacon, egg yolks, and fatty cuts of meat. This will help reduce cravings and keep you feeling satisfied. It's important to note that the keto diet is not a low-fat diet, and adequate fat intake is crucial to speed up the transition to burning fat for energy.
Remember, the keto flu is a temporary condition, and these strategies can help you manage the symptoms more effectively. Listen to your body and consult with a healthcare professional if you have any concerns or if your symptoms persist or worsen.

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. This happens when the body adapts to a new diet consisting of very few carbohydrates. Symptoms of keto flu include fatigue, muscle soreness, nausea, dizziness, and sugar cravings, among others. These symptoms can range from mild to severe and can last from a few days to several weeks. In extreme cases, they can last up to a month.
If your symptoms don't improve after a couple of weeks, or if you experience a fever or vomiting, it is important to consult a doctor. A fever can be a sign of dehydration, which can occur when the body rapidly sheds water stores on a keto diet. Dehydration can also be caused by the consumption of carbs after being on a low-carb diet for a while, as the fluid you drink is used to process the carbs. Additionally, a sudden reintroduction of carbs can cause a crash feeling, similar to the "crash" after a sugar high.
If you are experiencing a fever, it is important to rule out other causes and ensure that you are properly hydrated. Drinking plenty of water and consuming electrolytes can help with hydration. However, if you are experiencing persistent or severe symptoms, it is best to seek medical advice.
Vomiting may also be a symptom of the keto flu, but if it persists or is severe, it could indicate another issue. It is always better to be cautious and consult a medical professional if you have any concerns or if your symptoms do not improve. They can provide guidance and advice tailored to your specific situation.
