Understanding Keto Flu: Causes And Symptoms Explained

The keto flu is a set of symptoms that some people experience when they start a ketogenic diet. The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein. The keto flu is not an actual flu, but it can cause side effects like fatigue, headaches, nausea, dizziness, and irritability. Symptoms usually appear within the first few days of starting the diet and can last for several days or weeks. The keto flu is believed to be caused by the body's adjustment to a new diet and the sudden reduction in carbohydrate intake.

Keto flu is a result of the body adapting to a new diet

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. The symptoms, which can feel similar to the flu, are caused by the body adapting to a new diet consisting of very few carbohydrates.

The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein. The intention is to put the body in a state of ketosis, where it burns stored fat instead of glucose for energy. This drastic reduction in carbohydrates can come as a shock to the body, and may cause withdrawal-like symptoms.

The keto flu is not caused by a virus, but it can make you feel under the weather. Symptoms include fatigue, headaches, nausea, dizziness, irritability, brain fog, trouble sleeping, and constipation. These symptoms are the result of temporary imbalances in energy sources, insulin, and minerals in the body. The lack of carbohydrates decreases insulin in the bloodstream, which can lead to an increase in sodium, potassium, and water released in the urine, causing dehydration.

The symptoms of keto flu usually appear within the first few days of starting the diet, and can last from a few days to several weeks. They can range from mild to severe, and while some people may transition to a ketogenic diet without any side effects, others find it challenging.

The keto flu is a result of the body adapting to a new diet, specifically the significant reduction in carbohydrate intake.

Carbohydrate withdrawal is a key factor

The keto diet typically restricts carbohydrate consumption to 20 to 50 grams per day, a substantial decrease from the recommended daily intake of 200 to 300 grams. This abrupt change in fuel sources can lead to a range of flu-like symptoms, including headaches, fatigue, nausea, constipation, and insomnia. These symptoms, known as keto flu, usually appear within the first few days of starting the keto diet and can last from a few days to several weeks.

The keto flu is not caused by a virus, but rather by the body's response to a sudden reduction in carbohydrate intake. It is important to distinguish it from the standard flu, which has different symptoms, such as nasal congestion. However, the keto flu can cause similar aches and pains, as well as fatigue, dizziness, irritability, and brain fog.

The onset of keto flu can be influenced by individual factors, such as the number of carbohydrates routinely consumed before starting the keto diet and the strictness of the carbohydrate restriction. For example, those who consumed a high number of carbohydrates before starting the keto diet and then drastically reduced their intake are more likely to experience keto flu.

To summarise, carbohydrate withdrawal plays a crucial role in triggering keto flu. The keto diet's significant reduction in carbohydrate intake forces the body to adapt to using fat as fuel, leading to flu-like symptoms that can vary in intensity and duration. Understanding this connection is essential for managing and mitigating the effects of keto flu.

Dehydration is common due to the loss of glycogen stores

Dehydration is a common symptom of the keto flu, which is a collection of symptoms experienced by some people when they start a ketogenic diet. The keto diet is very low in carbohydrates, which forces the body to burn ketones for energy instead of glucose. Ketones are byproducts of fat breakdown and become the main fuel source when following a ketogenic diet.

The body stores extra sugar in a molecule called glycogen. Glycogen is generally kept in the cells, along with a lot of water. When you go into ketosis, your body dumps the water that was stored with the glycogen, which can lead to dehydration. This is because when dietary carbohydrates are reduced, glycogen levels plummet and water is excreted from the body.

To prevent dehydration when starting a keto diet, it is important to drink plenty of water. If you were consuming a lot of sugary drinks before starting the diet, this is even more important, as you are cutting out a significant source of hydration.

In addition to drinking enough water, it is also important to replace lost electrolytes. When your body dumps water, it often releases electrolytes as well. This is especially true when insulin levels decrease. Many of the keto flu symptoms, such as fatigue, muscle cramps, and body weakness, may be caused by your body's reaction to low levels of electrolytes. Adding more salt to your food or drinking sports drinks that are high in electrolytes can help your body adjust to ketosis more smoothly.

Symptoms can last from a few days to several weeks

The keto flu is a collection of symptoms experienced by some people when they start a ketogenic diet. The symptoms can range from mild to severe and vary from person to person. While some people may transition to a ketogenic diet without any side effects, others may experience symptoms such as fatigue, headaches, nausea, and constipation. These symptoms are due to the body adapting to a new diet consisting of very few carbohydrates.

The keto flu can last from a few days to several weeks. During this time, it is important to support your body during its transition into ketosis. Your body uses carbs for various functions, including electrolyte balance and hydration, so cutting carbs can cause discomfort. Here are some ways to help your body adjust and reduce the symptoms:

• Drink plenty of water: The keto diet can deplete your water stores, putting you at risk of dehydration. Drinking enough water is crucial for preventing dehydration and minimizing symptoms like fatigue.
• Get enough electrolytes: When your body releases water, it also releases electrolytes. Adding more salt to your food or drinking sports drinks high in electrolytes can help your body adjust to ketosis.
• Eat healthy fats: The keto diet can reduce your appetite, but when combined with nausea from keto flu, it may be challenging to eat enough calories. Ensure you are getting enough healthy fats in your diet to increase your energy levels and reduce nausea.
• Rest and avoid heavy exercise: While your body is adjusting to the new diet, it is crucial to rest and give it time to work. Avoid strenuous exercise during the first week and opt for lighter activities such as yoga or stretching.
• Consider a slower transition: Many keto flu symptoms result from a sudden dietary shift. Instead of immediately limiting your carbohydrate intake, try reducing your carb intake gradually over a few days or weeks to help your body adjust naturally.

Treatment includes staying hydrated, resting and eating more fat

If you are experiencing keto flu, it is important to stay hydrated, rest, and eat more fat. Here are some detailed tips to help you manage the symptoms:

• Stay hydrated: Drink plenty of water to prevent dehydration. The keto diet can deplete your water stores, and the loss of glycogen during ketosis can lead to water excretion, increasing the risk of dehydration. Water will help to flush your system and prevent dehydration, especially if you experience vomiting or diarrhea.
• Rest: Avoid strenuous exercise during the first week of the keto diet. Fatigue, muscle cramps, and stomach discomfort are common in the initial days of the diet, so it is important to give your body time to rest and adjust. Focus on lighter activities such as walking, yoga, or leisurely biking, which may help improve symptoms.
• Eat more fat: Ensure you are consuming enough healthy fats in your diet. Transition gradually by slowly cutting back on carbohydrates while increasing your fat and protein intake. This can help reduce cravings for restricted foods and make the transition smoother. Eating more fat will also help you feel more satisfied and reduce cravings.

In addition to the above measures, it is also recommended to get adequate sleep, avoid caffeine, and adjust your workout routine if you are experiencing keto flu symptoms. While the keto flu can be unpleasant, it is usually temporary, and these measures can help reduce its impact.
