Keto Flu: Lingering Symptoms After Keto?

The keto flu is a collection of symptoms that some people experience when starting a ketogenic diet. The ketogenic diet is a popular weight-loss method that involves drastically reducing carbohydrate intake and increasing fat consumption. The body's response to this sudden change can often mimic flu symptoms, hence the name keto flu. Symptoms can include stomach aches, nausea, dizziness, sugar cravings, muscle soreness, irritability, and diarrhea, among others. While the keto flu can be unpleasant, there are ways to manage and reduce its symptoms, and it is generally a temporary condition.

Keto flu symptoms: fatigue, muscle soreness, nausea, dizziness, and more

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. The symptoms, which are usually mild and short-term, arise as the body gets used to operating with fewer carbohydrates and as it enters a state of ketosis.

The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein. The drastic reduction in carbohydrates can come as a shock to the body, which may respond with withdrawal-like symptoms.

Symptoms of keto flu can include:

• Fatigue
• Muscle soreness
• Nausea
• Dizziness
• Sugar cravings
• Cramping
• Irritability
• Diarrhea or constipation
• Trouble sleeping
• Poor focus and concentration ("brain fog")
• Headaches
• Abdominal pain
• Vomiting

These symptoms typically develop within the first few days of starting a ketogenic diet and can last from a few days to several weeks. However, in extreme cases, they can persist for up to a month.

To alleviate keto flu symptoms, it is recommended to:

• Stay hydrated by drinking plenty of water
• Increase salt and electrolyte intake to replace lost electrolytes
• Consume more healthy fats
• Get plenty of rest and avoid strenuous exercise
• Ease gradually into the ketogenic diet rather than making a sudden change

Causes of keto flu: carbohydrate withdrawal, change in gut microbiome, etc

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. The symptoms can include headache, brain fog, fatigue, irritability, nausea, difficulty sleeping, and constipation. The exact cause of keto flu is unknown, but it is believed to be caused by a combination of factors, including carbohydrate withdrawal, changes in the gut microbiome, genetics, dehydration, and a drastic reduction in carbohydrate intake.

Carbohydrate withdrawal: The ketogenic diet is very low in carbohydrates, which are the body's main source of energy. When carb intake is reduced, the body is forced to burn fat for energy instead, leading to a state of ketosis. This switch to burning fat can be a shock to the system and may trigger withdrawal-like symptoms similar to those experienced when weaning off addictive substances.

Change in gut microbiome: Studies have shown that a very low-carb diet can affect the diversity and composition of gut bacteria. Some research suggests that a low-carb diet reduces total bacterial levels and beneficial anti-inflammatory species, while other less desirable species increase. These changes in the gut microbiome could be a contributing factor to the symptoms associated with keto flu.

Genetics: Not everyone experiences keto flu, and it is believed that genetics may play a role in an individual's susceptibility. Some people are naturally "metabolically flexible," meaning they can easily shift between metabolic states without experiencing negative health symptoms.

Dehydration: The keto diet can cause a rapid loss of water stores in the body, leading to dehydration. Dehydration can exacerbate symptoms such as fatigue and muscle cramps. Staying adequately hydrated is crucial when following the keto diet.

Drastic reduction in carbohydrate intake: The ketogenic diet typically involves reducing carbohydrate intake to 20-50 grams per day, which is a drastic change for most people. This sudden and significant reduction in carbs can be a shock to the body and may trigger the symptoms associated with keto flu.

How to know if you have keto flu: symptoms typically appear within the first few days of starting a keto diet

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

Signs of the keto flu typically start appearing within the first few days of cutting back on carbs. The symptoms can range from mild to severe and vary from person to person.

• Headache
• Foggy brain or difficulty focusing
• Fatigue
• Irritability
• Nausea
• Difficulty sleeping
• Constipation or diarrhoea
• Muscle soreness
• Cravings
• Low blood sugar
• Bad breath

The keto flu is not contagious or dangerous, and it is usually temporary. The symptoms usually last a few days to a few weeks, and in some cases, they may last up to a month.

If you are experiencing the keto flu, there are several things you can do to reduce the symptoms:

• Drink plenty of water: The keto diet can cause dehydration, so it is important to stay hydrated.
• Eat more fat: Increasing your fat intake can help reduce cravings and keep you feeling satisfied.
• Transition gradually: Slowly cut back on carbs while increasing your fat and protein intake. This can help ease the transition to the keto diet.
• Adjust your workout routine: Avoid strenuous exercise and focus on lighter activities such as walking or yoga.
• Moderate caffeine intake: Caffeine can disrupt sleep, so it is recommended to cut back, especially if you are having trouble sleeping.

How long does keto flu last: symptoms can last from a few days to several weeks

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. This happens when the body enters ketosis, burning fat for energy instead of carbohydrates (glucose). The symptoms of keto flu are similar to those of the flu and are caused by the body's response to the withdrawal from carbs.

The keto flu can last from a few days to several weeks, and in some cases, up to a month. The duration depends on individual factors, such as genetics and the body's ability to adapt to a new diet. Some people may never experience the keto flu if they are naturally "metabolically flexible".

The symptoms of keto flu typically begin within the first day or two of starting the ketogenic diet. They can include stomach aches, nausea, dizziness, sugar cravings, cramping, muscle soreness, irritability, diarrhoea, constipation, trouble sleeping, poor focus, and brain fog.

To manage the symptoms of keto flu, it is recommended to ease into the diet gradually, stay hydrated, and ensure adequate electrolyte intake. Getting plenty of rest and light exercise can also help.

How to get rid of keto flu: increase water and salt intake, eat more fat, etc

The keto flu is a collection of symptoms experienced by some people when they first 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.

• Increase water and salt intake: The keto diet can cause you to rapidly shed water stores, increasing the risk of dehydration. Drinking enough water is necessary for optimal health and can also help reduce symptoms. Staying hydrated can help with symptoms like fatigue and muscle cramping. In addition, salt your food heavily to help your body retain fluids.
• Eat more fat: A well-balanced keto diet includes enough fat to ensure you’re not hungry after a meal, can go for several hours without eating, and have ample energy. Be sure to increase your intake of fat at the start of your keto journey until your body adapts to using fat and ketones for most of its energy needs.
• Eat more keto-friendly foods: When you first begin the ketogenic diet, you may feel particularly hungry and have strong cravings for carbohydrates. During this adjustment period, focus on following your recommended keto macros without focusing too much on calorie consumption.
• Replace electrolytes: When following a ketogenic diet, levels of insulin, a hormone that helps the body absorb glucose from the bloodstream, decrease. As a result, the kidneys release excess sodium from the body. Getting adequate amounts of these important nutrients can help power you through the adaptation period of the diet.
• Get enough sleep: It is important to rest and allow your body to work when adjusting to a new diet. Make sleep a priority to help combat zapped energy levels.
• Consider a slower transition: Many of the symptoms of keto flu are the result of a sudden dietary shift. If you find that keto flu makes it difficult to stick with a keto diet, you can ease into it instead of immediately and severely limiting your carbohydrate intake. Reducing your carb intake gradually can help your body adjust to your new diet naturally and without the negative symptoms.
