The Keto flu. It's a feeling that anyone who has tried the ketogenic diet is familiar with; a set of unpleasant symptoms that can temporarily make life difficult. But what causes this phenomenon?
In this article, we'll explore what it is, why some people get it, and how to manage it so you can enjoy the long-term benefits of the keto diet. So if you've ever felt tired and foggy after starting the keto diet, read on to find out why—and what you can do about it.
What is Keto Flu?
Keto flu is an umbrella term for the symptoms people often experience when transitioning to a ketogenic diet. These can include fatigue, headaches, brain fog, difficulty concentrating, and nausea or irritability.
While not everyone experiences these issues while on a low-carb diet, they are familiar enough that they have been given their name—" keto carb flu."
While the precise origin of keto flu is uncertain, it is considered connected to dehydration and electrolyte imbalances brought on by a rapid reduction in carbohydrate consumption. Additionally, some people may also experience withdrawal from sugar and starchy foods. When your body adjusts to its new fuel source, these symptoms typically subside in days or weeks.
What Causes Keto Flu?
Some people experience what is known as "Keto Flu" when they switch to a low-carbohydrate, high-fat diet. These symptoms typically include fatigue, nausea, headaches, dizziness, constipation, and irritability. The Keto Flu results from the body's reaction to a dramatic shift from carbohydrates to fat.
As the body shifts from burning glucose for energy (from carbohydrate sources) to burning fat for energy (ketosis), it can take time for the body to adapt. Many experience uncomfortable symptoms during this adaptation period due to low blood sugar levels and electrolyte imbalances. Other possible causes may include dehydration due to increased water loss during keto-adaptation or changes in gut bacteria associated with dietary changes.
How to Eliminate the Keto Virus
Keto Flu can be an unpleasant experience, but there are strategies to alleviate its flu-like symptoms and facilitate a smoother transition for your body. Staying hydrated and maintaining adequate electrolyte levels through foods like avocados, nuts and seeds, spinach and other leafy greens, olives and olive oil, dairy products such as yogurt or kefir, and meats like turkey or salmon can help relieve symptoms.
Additionally, consuming more sodium may also help reduce symptoms tend Keto Flu. Eating numerous little meals regularly throughout the day instead of skipping meals can keep your blood sugar levels stable and reduce your weariness.
Finally, getting enough restful sleep can also minimize Keto Flu symptoms. With these simple steps, you will be feeling better in no time!
One of the most significant ways to lessen the effects of the Keto Flu is to drink lots of water. When your body moves from using carbohydrates as energy primarily to using fat, it causes a rapid loss of water.
This water loss can lead to dehydration, increasing the likelihood of experiencing Keto Flu symptoms like fatigue and muscle cramping. Get in your daily recommended 8-10 glasses of water, and more if it's hot or you're exercising heavily.
Consuming more sodium may also be beneficial for reducing Keto Flu. All these simple changes will help you lose weight and keep you healthy and energized while transitioning into ketosis.
Avoid Strenuous Exercise
When transitioning to a ketogenic diet, it is important to avoid strenuous exercise. This is especially true when experiencing Keto Flu symptoms such as fatigue, muscle cramps, and stomach discomfort.
Intense activities such as running, weight lifting, and biking should be avoided until your body fully adapts to the new fuel source. Instead, focus on light activities that don't strain the body or require a lot of energy, such as walking, yoga, and leisurely biking.
These can help improve the symptoms of the keto while allowing your body time to adjust. Staying hydrated is also essential for reducing Keto Flu symptoms; drinking 8-10 glasses of water daily will help keep your body balanced and energized during this transition period.
Replacing electrolytes is an integral part of managing Keto Flu symptoms. Electrolyte imbalances can lead to dizziness, fatigue, muscle cramps, and other uncomfortable side effects. This is especially true when transitioning to a ketogenic diet, as the body has to adjust to burning fat instead of carbohydrates for energy.
Eating foods naturally high in electrolytes like avocados, nuts and seeds, spinach and other leafy greens, olives and olive oil, dairy products such as yogurt or kefir, and meats like turkey or salmon can help maintain balance. Additionally, salting food to taste is easy to ensure your body has enough sodium.
What are Keto Flu Symptoms
Have you ever heard of the dreaded "keto flu"? It's a set of symptoms that many people experience when transitioning to the ketogenic diet.
If you've been considering this popular low-carb lifestyle, it helps to understand keto flu symptoms and how to manage them. From fatigue and weakness to bad breath and nausea, here's what you need to know about this common phenomenon.
Why do some individuals get keto flu?
The Keto Flu is a collection of signs and symptoms that some experience upon beginning or resuming a ketogenic diet. It usually occurs because the body uses fat for energy instead of carbohydrates.
Symptoms include fatigue, headache, nausea, constipation, and muscle cramps. While not all people experience Keto Flu when switching to a keto diet, some do. The primary cause is an electrolyte imbalance due to the body eliminating too much water from reduced carb intake.
This can lead to dehydration and mineral deficiencies, which can cause these symptoms. Additionally, people who consume large amounts of refined carbs may have difficulty transitioning and thus may experience more intense Keto Flu symptoms.
To help with this transition, getting adequate sleep, drinking plenty of fluids, and eating nutrient-dense foods like nuts, seeds, and leafy greens to replenish lost minerals is essential. Following these steps should help reduce or eliminate all the unpleasant side symptoms typically associated with Keto Flu.
Keto Flu Symptoms
Fatigue and Weakness
Fatigue and weakness are two of the most commonly reported keto flu symptoms. This is because the body needs time to adjust to using fat for energy instead of carbs when transitioning to a low-carb diet. During this transition period, some people may experience feelings of tiredness and sluggishness.
This feeling can be especially pronounced if you lack sleep or have an active lifestyle. To help combat fatigue and weakness during the first experience of keto flu symptoms, it's essential to get plenty of restful sleep and stay hydrated with plenty of fluids.
Additionally, adding electrolytes such as sodium, magnesium, and potassium to your diet can help replenish minerals lost through increased urination associated with low-carb diets.
Finally, eating more nutrient-dense foods like leafy greens, avocados, nuts/seeds, fatty fish, cage-free eggs, grass-fed beef, and coconut oil/butter can provide essential vitamins and minerals your body needs for energy production.
Constipation or Diarrhea
Constipation or diarrhea can be expected during the keto flu. Increasing water intake and eating more fiber-rich foods are essential to help alleviate these symptoms.
Increasing your intake of electrolytes, such as sodium, magnesium, and potassium, may also help. Other dietary strategies include consuming fermented foods such as sauerkraut or kimchi and probiotics which can help to balance out your gut bacteria.
Limiting carbohydrate intake, sugar alcohols, and artificial sweeteners can also be beneficial, which can have a laxative effect on some people. Taking a digestive enzyme supplement with meals may also help to improve digestion. If symptoms persist for an extended period, you must consult your healthcare provider for further evaluation and treatment options.
A typical symptom of the keto flu is headaches. Mild to severe headaches might be caused by dehydration, electrolyte imbalances, or dietary modifications. Consuming copious amounts of water throughout the day is vital to maintain hydration and electrolyte balance with sodium, magnesium, and potassium.
Caffeine can also help alleviate headaches but should be consumed in moderation as it may lead to dehydration. Additionally, avoiding processed foods which contain added sugars and artificial sweeteners can help reduce the severity of headaches. If you've tried these methods and are still experiencing headaches, you must see a doctor to rule out more serious causes.
One of the symptoms of keto flu is poor breath (halitosis). It is caused by increased acetone production when your body enters ketosis.
Acetone is a breakdown product of fatty acids with a distinct odor that can cause bad breath. Staying hydrated and brushing your teeth regularly is essential to combat lousy breath.
Additionally, avoiding processed food and sugary snacks can help reduce the number of bacteria that produce odors in your mouth. Eating crunchy fruits and vegetables such as celery and apples can help promote saliva production and encourage natural mouth cleansing.
Nausea is a common symptom of the keto flu, ranging from mild to severe. For mild cases, eating smaller meals more frequently or snacking on low-carbohydrate snacks throughout the day may help reduce symptoms. Additionally, drinking plenty of fluids and avoiding foods high in fat or fiber can help alleviate nausea.
Eating and drinking slowly can also help with digestion and prevent your body from feeling overwhelmed by large amounts of food at once. For more severe cases, medications such as antacids and antiemetics may be recommended by your healthcare provider to help reduce nausea and vomiting.
Supplementing with electrolytes like sodium and potassium can also benefit those experiencing nausea due to electrolyte imbalances caused by the ketogenic diet.
Muscle cramps are a common symptom of the keto flu, especially during transitioning to a low-carb, high-fat new diet. When you lose weight, your body adjusts from using carbohydrates for energy to burning fat, which can lead to an electrolyte imbalance and muscle cramps.
Electrolytes like sodium, potassium, and magnesium can become depleted in the body, which can lead to dehydration and muscle cramps.
Staying hydrated and supplementing with electrolytes to reduce muscle cramps is essential. You should also ensure you get enough sleep and manage your stress levels, as these can contribute to electrolyte imbalances that cause muscle cramps.
Eating potassium-rich foods like spinach, avocados, and bananas and taking an electrolyte supplement may help replenish lost electrolytes and reduce muscle cramp symptoms.
While switching to a ketogenic diet, muscle cramps frequently occur. Still, they don't have to be permanent if you ensure you are adequately hydrated, supplemented with electrolytes, getting enough restful sleep, and managing stress levels.
