Treatments for Keto Flu
Starting a ketogenic diet can be a transformative journey, but it may come with challenges like the keto flu—a collection of symptoms that mimic the flu as your body adapts to a low-carb lifestyle. These symptoms can disrupt your progress, but with proper management, they don’t have to derail your goals.
Managing keto flu involves replenishing electrolytes, staying hydrated, and gradually transitioning into the diet to ease your body into fat-burning mode. However, this approach may not be suitable for everyone. Individuals with pre-existing health conditions should always consult a healthcare provider before adopting a ketogenic diet to avoid potential risks.
By understanding how to treat keto flu and recognizing if keto is right for you, you can make informed decisions and adjustments that protect your health while achieving your dietary objectives. A thoughtful approach ensures long-term success without compromising your well-being.
Managing Keto Flu
Navigating through the initial phase of the ketogenic diet can be challenging due to the manifestations of the keto flu. However, several effective management efforts can help alleviate these symptoms and make the transition smoother until you are fully adjusted.
Increase Fluid Intake and Electrolytes
As your body shifts to burning fat for fuel, it can increase water loss through urine. This diuretic effect can cause dehydration if not taken care of. Drinking plenty of water and consuming electrolyte-rich foods and supplements is essential for optimal hydration.
Electrolyte solutions and sports drinks that contain sodium, potassium, and magnesium are helpful, though sugar-free versions are ideal for a ketogenic diet. Adding salt to food or drinking broth can increase sodium intake, and consuming leafy greens can boost potassium levels. Nuts and seeds provide a rich source of magnesium.
Incorporating electrolyte-rich foods and supplements is an effective strategy to alleviate the discomforts of keto flu and promote a smoother transition into ketosis. Proper hydration with electrolytes helps reduce symptoms like muscle cramps and headaches and minimizes the severity and duration of keto flu.
Avoidance of Intense Physical Activities
During the initial phase of ketosis, your body adapts to a new energy source, leading to decreased energy levels and increased fatigue. This temporary energy deficit can make you tired, lightheaded, and prone to muscle cramps or dizziness. Strenuous physical activities can worsen these symptoms and increase exhaustion.
Avoid intense activities in the meantime and allow your body to adjust to the new diet. Focus on gentle, low-impact activities like walking, stretching, or light yoga to help maintain some workout without overwhelming the body. These exercises can promote blood circulation and flexibility while reducing the risk of injury.
When energy levels improve, you may gradually resume more intense physical activities. A progressive exercise intensity as keto flu symptoms subside allows for a smoother transition to an entire workout routine without putting too much strain on the body during the adjustment period.
Adequate Rest and Sleep
Adequate rest and sleep are vital in managing keto flu. Your body is undergoing significant metabolic changes, which can be physically stressful. Adequate rest allows your body to recover, reduce fatigue, and adjust more efficiently to the new diet.
Prioritizing rest and sleep in the early days of the ketogenic diet will help accelerate this adaptation process by balancing cortisol levels, reducing the duration of keto flu symptoms, promoting mental clarity, regulating energy, and preventing the body from becoming overexerted

Establishing a consistent bedtime routine and reducing blue light exposure in a restful environment helps with better sleep quality while managing keto flu symptoms.
Gradual Dietary Adjustments
Easing into the ketogenic diet gradually rather than making an abrupt shift can help mitigate the symptoms of the keto flu. A gradual dietary adjustment also provides psychological benefits. Slowly reducing carbohydrate intake over days or weeks gives your body more time to adapt while minimizing side effects and discomfort.
This slower approach can lessen the shock to your system, potentially reducing the severity and duration of keto flu symptoms. A gentle transition helps avoid the sudden drop in blood sugar and minimize the likelihood of headaches and fatigue. This also reduces intense cravings and emotional stress during the transition.
Eat Enough Fat Sources
Consuming adequate amounts of fat during the transition period is essential on a ketogenic diet since fat becomes your primary energy source. Eating enough fat can help prevent energy dips and support your body’s transition into ketosis.
Healthy fats, such as those found in avocados, olive oil, nuts, and fatty fish, help ensure the body has a steady and reliable energy supply as it adapts to ketosis. This allows for a smoother transition and reduces symptoms of keto flu. Keeping moderate carbohydrates, especially from fiber-rich vegetables and low-carb fruits, ensures a backup fuel source.
Consume MCT Oil
Medium-chain triglycerides (MCT) from coconut oil is a supplement that can help your body produce ketones more efficiently, aiding in the transition into ketosis. MCTs are quickly absorbed and converted into ketones, providing an immediate energy source. Including MCT oil in your diet can also help reduce cravings and provide sustained energy levels.
This can support better digestion and reduce digestive discomfort during keto flu, making the adaptation period more manageable. However, this should be introduced gradually to avoid digestive discomfort. Add MCT oil to your morning coffee or tea. Mixing with butter or heavy cream can create a creamy, energy-boosting drink that provides sustained energy.
You can add MCT oil to a smoothie and blend it with other ingredients like avocado, coconut milk, or protein powder to reduce the taste and reap the benefits. This oil can also be used in salad dressings or incorporated into keto baked goods to add variety to your diet.
Is the Keto Diet Safe?
Although the ketogenic diet can offer benefits for many, it may not be appropriate for everyone. Certain groups of people should avoid it due to potential health risks. Understanding why this diet may not be applicable to your case helps you decide if this diet is suitable for you.
Liver Conditions
If you have liver conditions, such as cirrhosis or fatty liver disease, a ketogenic diet may not be suitable. When the liver is weakened, it may struggle to process by-products of fat metabolism, like acetone and acetoacetate, causing additional strain on the organ.
With compromised liver function, it may be difficult for your body to process and produce energy from fats efficiently. The reliance on a keto diet will add strain to the existing liver problems, affecting overall wellness.
Kidney Disease
A ketogenic diet can cause electrolyte imbalances due to its diuretic effect and can worsen the condition of people with kidney disease. Dehydration, a common consequence of keto flu, can lead to further kidney stress, causing additional complications such as fluid retention, swelling, or even acute kidney injury.
The keto diet also increases calcium and oxalate excretion, which can combine to form crystals in the kidneys, potentially leading to kidney stones. If you still decide to try this diet, monitoring and maintaining kidney health is crucial in this management.
Diabetes
Individuals with diabetes, especially type 1, who struggle with blood sugar regulation, should be cautious with a ketogenic diet. They are more vulnerable to these extreme changes in blood sugar levels since sudden changes in diet can lead to hypoglycemia, as it becomes challenging to maintain stable glucose.
In ketosis, the body produces more ketones, which can sometimes lead to a dangerous condition called diabetic ketoacidosis (DKA). DKA causes very high ketone levels, acidic blood, and symptoms like nausea, confusion, and fruity-smelling breath. In severe cases, it can lead to a coma or even death.
Pregnant or Breastfeeding
Pregnant or breastfeeding women should avoid the ketogenic diet due to the increased nutritional demands. During pregnancy, the body requires glucose for the baby’s developing brain. Nutrients like folate, iron, and calcium may be insufficient on a ketogenic diet, impacting fetal and maternal health.
A ketogenic diet may not provide enough carbohydrates to meet the higher energy needs during breastfeeding. Pregnant and breastfeeding women should consult with a healthcare professional before making significant changes in their diet, especially if considering the keto diet.
Eating Disorders
Individuals with a history of eating disorders should not follow a ketogenic diet. The restrictive nature of the ketogenic diet can pose a significant risk for individuals with eating disorders, who often struggle with food control, nutrient absorption, and irregular eating patterns.
The stress of following the keto diet can trigger a relapse for individuals recovering from eating disorders. The restrictive nature of the keto diet can trigger cravings for comfort foods, leading to bingeing, purging, or emotional eating.
A sudden and drastic change in the ketogenic diet, especially one that severely limits carbohydrates, can increase feelings of guilt and shame around food. This can lead to unhealthy relationships with food, food avoidance, compulsive exercising, or compulsive eating. Individuals with eating disorders should prioritize mental health and find alternatives.
Keto Flu Symptoms and When to See a Doctor
If you’ve recently started a ketogenic diet, you may have noticed some unexpected side effects. Keto flu is a set of symptoms you might experience after starting a keto diet. Since your body is adjusting to the new eating method, it can feel like you’re coming down with the flu.
In this article, we’ll explore Keto Flu, why it happens, and when to seek the help of a healthcare professional, whether you’re just starting keto or are struggling with lingering effects, you’ll discover why one experiences this condition and confirm the need to see a doctor.
Understanding Keto Flu
The ketogenic diet has gained popularity for its potential benefits in weight loss, but the transition from a regular diet into ketosis can come with its own set of challenges. Read the reasons behind keto flu, why it affects some people more than others, and how long these symptoms typically last.
What is Ketosis?
Once you reduce carb intake (less than 50 grams daily for some), the liver breaks down fat into fatty acids and ketone bodies. When the body uses fat as a new energy source, it enters a state called “ketosis.” This metabolic change can trigger “keto flu.”
The transition to ketosis uses glycogen (glucose) stored in the liver, along with water. When carbohydrate intake drops, the body depletes glycogen stores and releases water. For some, these changes may be overwhelming and cause a range of symptoms interpreted as Keto Flu.
Why Does “Keto Flu” Happen?
Keto flu is more likely to affect people new to a low-carb, high-fat diet since it causes electrolyte imbalances and dehydration. Not everyone experiences keto flu, but it can happen to those who significantly reduce their carbohydrate intake as the body switches its energy source.
While some bodies adapt more smoothly to the metabolic shift, keto flu symptoms can be more intense for those with hormonal imbalances when combined with electrolyte loss, including those of sodium, potassium, and magnesium. The severity can vary based on diet history, age, and lifestyle.
How Long It Lasts
Keto flu typically lasts for a few days to a week. Symptoms can start within the first few days of starting a ketogenic diet and become intense during the initial transition period as the body drastically adjusts to a low-carbohydrate diet.
Duration varies based on factors like metabolic health, electrolyte balance, previous diet, and how quickly the body adapts to ketosis. For the majority, most symptoms subside after 3-4 days and can persist for up to 1 – 2 weeks for complete adaptation to the new diet.
Symptoms of Keto Flu
Starting a ketogenic diet can bring about many changes, and for some, this transition is accompanied by a series of uncomfortable symptoms. Please take a closer look at the common symptoms of Keto flu and what causes them.
Fatigue and Weakness
Fatigue and weakness are common when your body is adjusting to ketosis. The shift from using glucose to fat for energy can initially make you feel tired and weak. This period of exhaustion is temporary but can be quite noticeable, especially in the first few days.
Glycogen is a form of sugar stored in your liver and muscles that your body uses for quick energy. When you reduce carbohydrate intake, your body uses the stored glycogen, causing a loss of electrolytes like sodium and potassium, which leads to feelings of sluggishness and overall low energy.
Nausea and Vomiting
When you start a low-carb diet or fast, your body produces less insulin. This causes your kidneys to eliminate sodium and water, causing you to lose essential minerals like potassium, magnesium, and sodium.
When vital minerals are depleted, digestive processes become impaired, leading to gastrointestinal discomfort. Dehydration can also trigger nausea as the body adjusts to reduced water and electrolyte levels, which can then lead to vomiting.
As your body burns fat for energy, the liver produces acetone and other chemicals. These are by-products of fat breakdown. High levels of acetone can cause a fruity smell on your breath, known as “keto breath,” and can also make you feel nauseous.
Bowel Problems
A ketogenic diet typically involves a drastic reduction in carbohydrates, which includes cutting out many high-fiber foods such as whole grains, fruits, and certain vegetables. Fiber is essential for healthy digestion and regular bowel movements.
Lower fiber intake slows digestion, leading to difficulty passing stool and constipation. Without adequate fiber, the gut may also become prone to bloating and cause stomach discomfort, especially in the early stages of the diet.
Irritability
Bad moods occur as your body adjusts to ketosis. The switch to relying on burning ketones for energy causes a drop in blood sugar levels and spikes cortisol, the stress hormone, which may increase stress and anxiety. Additionally, reduced serotonin and dopamine levels—linked to lower food intake—can lead to irritability.
The drastic dietary shifts related to carbohydrate restriction and blood sugar fluctuation, combined with reduced energy and hormonal changes, can significantly impact your mood and mental state, making you more irritable. The absence of familiar comfort foods during the initial stages of the keto diet can further heighten feelings of frustration.
Brain Fog
The brain usually relies on glucose for quick energy. When switching from a high-carbohydrate diet to a low-carb ketogenic diet, it takes time for the brain to adapt to using ketones efficiently. The brain function may be affected during the energy production adjustment period, causing brain fog.
Brain fog can make you feel mentally sluggish or unfocused. The brain may experience temporary cognitive impairment, including dizziness and difficulty making decisions. This leads to feelings of mental fatigue, lack of focus, and difficulty concentrating.
Sleep Problems
When your body switches to ketosis, it temporarily produces more cortisol to help the body adapt to changes. However, elevated cortisol levels disrupt melatonin production, the hormone responsible for regulating sleep.
These disruptions can interfere with your sleep patterns, leading to difficulty falling asleep. In addition, the interruption of the normal sleep-wake cycle can also cause poor sleep quality, insomnia, and restlessness.
Muscle Cramps
Eating fewer carbs lowers insulin, prompting your kidneys to expel more sodium, potassium, and magnesium. These electrolytes are vital for nerve function, muscle relaxation, and contraction. When electrolytes in your body are out of balance, it can affect how your nerve cells work.
Low potassium can make your nerves overly active, causing muscle twitches. When electrolytes are deficient, muscles may contract involuntarily, leading to muscle cramps, especially in the calves, thighs, or feet, which are more susceptible to spasms when electrolyte levels are low.
Increased Hunger
Increased hunger is a common symptom when starting a ketogenic diet. Carbohydrate intake is drastically reduced, and blood sugar levels drop, causing the body to feel hungry. During the early stages of ketosis, ghrelin (the hunger hormone) levels may temporarily rise, increasing hunger.
In addition to physical hunger, habitual cravings can occur as you adjust to the new food options available, mainly if you are used to eating carbohydrate-rich food. These cravings can lead to a desire to eat even without a physical need for more calories.
When to See a Doctor
While keto flu is typically temporary and not severe, there are certain circumstances when it becomes necessary to consult a healthcare provider. Recognizing when more severe or unusual symptoms occur ensures a safe change in your diet regimen.
Persistent or Severe Symptoms
If you experience persistent or overwhelming symptoms that interfere with daily functioning, seeking medical attention is essential. Symptoms such as prolonged fatigue, intense headaches, or severe muscle cramps that don’t improve might indicate an underlying issue like dangerously low blood sugar levels, ketoacidosis, or critical electrolyte disturbances.
These severe symptoms could be a sign that your body isn’t adjusting well to the ketogenic diet. Persistent discomfort and pain signal that you need professional evaluation to ensure your health and safety.
Prolonged Symptom Duration
Keto flu symptoms usually last from a few days to a week. If your symptoms persist beyond this period, and your body struggles to adapt, potentially affecting your daily activities and energy levels, it might be worth taking a trip to the clinic.
The extended duration of symptoms may indicate a deeper health concern. Seeking medical advice can help identify and address any issues, recommend appropriate interventions, and guide you on how to proceed with your diet.
Extreme Dehydration
Extreme dehydration is a serious concern and requires immediate medical attention. The ketogenic diet’s diuretic effect can exacerbate fluid loss. Severe dehydration can manifest as dry mouth, dizziness, fatigue, dark urine, and rapid heartbeat, signaling dangerously low hydration and requiring prompt medical attention.
Severe dehydration caused by keto flu can lead to severe health consequences for heart, muscle, and nerve function. A healthcare professional can recommend and conduct appropriate interventions like oral rehydration solutions or IV fluids to rehydrate the body more effectively.
Significant Weight Loss
Rapid weight loss can be alarming and indicates your body is not adjusting well to a ketogenic diet. If the diet is too restrictive, it can lead to muscle wasting and nutrient deficiencies in the long term. In such cases, seeing a doctor to assess your nutritional intake is essential.
If you’re losing weight too quickly, seeking medical advice is essential. This could be a sign of other health concerns that must be addressed. Issues like thyroid problems, gastrointestinal disorders, or diabetes can affect weight maintenance, and strict diets may worsen these conditions.
Mental Health Impact
If you experience negative mental health impacts, such as severe mood swings, anxiety, or depression, consult a doctor, as ketosis can impact brain chemistry and overall mental state. These symptoms are usually temporary, but if they persist or intensify, it may signal an underlying mental health issue needing professional help.
Persistent mental health issues during the ketogenic diet may indicate that your brain is not adapting well to the new energy source. Professional advice can suggest mental health support through therapy or counseling, mainly if the symptoms are related to pre-existing issues like anxiety disorders or disordered eating.
