Keto And Flu: A Healthy Combination?

The ketogenic diet has become increasingly popular for weight loss. It involves drastically reducing your carbohydrate intake and increasing your fat and protein consumption. This forces your body to burn fat for energy instead of carbohydrates, which is known as ketosis. However, one of the most well-known complications of the keto diet is the keto flu. So, what is the keto flu, and what can you do to alleviate the symptoms?

Keto flu symptoms

The keto flu is a collection of symptoms experienced by some people when they start a ketogenic diet. The symptoms are similar to those of the flu and 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. This usually works out to 70% to 80% fat, 10% to 20% protein, and 5% to 10% carbohydrates. By reducing carbohydrates, you can force your body to burn fat for fuel.

The keto flu symptoms can occur within the first two days of starting the keto diet and can last from a few days to several weeks, and in some cases, even up to a month. The symptoms can range from mild to severe and vary from person to person.

Some of the most common keto flu symptoms include:

• Diarrhea or constipation
• Fatigue
• Headaches
• Dizziness
• Irritability
• Nausea
• Sugar cravings
• Muscle soreness and aches
• Cramping
• Trouble falling or staying asleep
• Poor focus and concentration
• Brain fog

The keto flu symptoms can be managed and reduced by:

• Staying hydrated: Drinking plenty of water can help reduce symptoms such as dizziness and headaches.
• Replacing electrolytes: Adding more salt to your food or drinking sports drinks that are high in electrolytes can help alleviate symptoms like muscle cramps and nausea.
• Getting enough rest: Keto flu can cause fatigue and sleep issues, so it's important to get 7-8 hours of sleep per day and avoid heavy exercise during the first week.
• Adjusting your diet: Ensure you're consuming enough healthy fats and calories. Gradually reducing your carb intake over a few days or weeks can help your body adjust naturally.
• Moderating caffeine intake: Caffeine can negatively impact sleep, so it's best to cut back, especially if you're experiencing trouble sleeping.

How to manage keto flu

The keto flu is a term used to describe the common side effects of the ketogenic diet. It is not an actual flu and is not contagious. The symptoms of keto flu include fatigue, restlessness, brain fog, impaired coordination, muscle soreness, stomach pain, bloating, constipation, diarrhoea, sugar cravings, dizziness, nausea, and confusion.

• Drink more water: The ketogenic diet causes a lot of water loss in the body, which can lead to dehydration. Aim for 16 cups of water per day, but listen to your body and adjust as needed.
• Replenish electrolytes: Electrolyte imbalance is the primary cause of keto flu. Sodium, potassium, and magnesium levels can be affected by the ketogenic diet, so it is important to replenish these electrolytes. Include more salt in your diet, drink bone broth, or take an electrolyte supplement.
• Eat more fat: The ketogenic diet relies on fat as the primary fuel source, so it is important to ensure you are consuming enough. Increase your intake of healthy fats such as coconut oil, olive oil, ghee, and fattier cuts of meat.
• Ease into keto gradually: You don't have to start the ketogenic diet all at once. Try cutting out refined sugar first, then starches, and eventually transition to a low-carb diet before going full keto.
• Eat nutrient-dense foods: In addition to macronutrient goals, the ketogenic diet is also about eating clean, whole foods. Include plenty of low-carb vegetables to get a wide range of micronutrients.
• Get plenty of rest: Lack of sleep can increase cortisol levels, which can amplify keto flu symptoms. Aim for 7-9 hours of sleep per night and take naps during the day if needed.
• Try light exercise: Light exercise, such as yoga or walking, can help improve your body's ability to switch between burning fat and sugar for fuel. It can also help release endorphins to boost your mood and motivation.

How long does keto flu last?

The keto flu is a collection of symptoms experienced by some people when they start a ketogenic diet. Symptoms can include nausea, headaches, fatigue, and sugar cravings, and they can range from mild to severe.

The keto flu can start within the first day or two of beginning the diet and typically lasts for a few days or up to several weeks. In extreme cases, symptoms can last up to a month. However, symptoms usually get better within 10 days. If symptoms persist or worsen, it is recommended to consult a doctor to rule out other causes.

To reduce the duration and severity of the keto flu, it is suggested to decrease carb intake slowly, stay hydrated, replace electrolytes, get enough sleep, and avoid strenuous activities.

What causes keto flu?

The keto flu is a collection of symptoms experienced by some people when they start a ketogenic diet. It is important to note that keto flu is not an actual flu, and you will not develop a fever. The symptoms 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 your 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, similar to those experienced when weaning off an addictive substance.

The most common causes of keto flu include:

• Sodium deficiency: Low-carb diets minimize the hormone insulin, which tells the kidneys to retain sodium. With less insulin, people on a keto diet excrete more sodium through urine, which can lead to sodium deficiency.
• Dehydration: The keto diet can cause a rapid loss of water stores, increasing the risk of dehydration. This is because glycogen, the stored form of carbohydrates, binds to water in the body. When dietary carbohydrates are reduced, glycogen levels drop and water is excreted.
• Carb withdrawal: Carbohydrates and sugar activate reward pathways in the brain, so eliminating them can cause carb cravings and other "withdrawal" symptoms.
• Reduced brain fuel: When you reduce your carb intake, your brain has to use fat as fuel. This transition can take some time, and cognition-related keto flu symptoms such as headaches, brain fog, and fatigue can occur during this period.

Other possible causes of keto flu include genetics, electrolyte loss, and carbohydrate withdrawal. While the exact causes are not fully understood, addressing these issues can help alleviate the symptoms.

Should you do keto?

The keto diet is a very low-carbohydrate, high-fat, and moderate-protein diet. It can result in rapid weight loss and potentially improve your health. However, it is associated with some unpleasant side effects, commonly known as the "keto flu."

The keto flu is a collection of symptoms that some people may experience when starting a keto 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. Symptoms can include stomach aches, nausea, dizziness, sugar cravings, muscle soreness, irritability, insomnia, poor concentration, and constipation, among others.

The keto flu is not a recognized medical condition, and its exact cause is unknown. It may be related to the body adjusting to a low-carb diet, sugar withdrawal, changes in the gut microbiome, genetics, dehydration, or a combination of these factors.

If you are considering the keto diet, here are some things you should know about the keto flu and how to manage it:

• The keto flu usually occurs within the first few days of starting the keto diet and can last for a few days to several weeks. In rare cases, it may last up to a month.
• Not everyone will experience the keto flu. Its occurrence and severity depend on individual factors.
• To minimize the impact of the keto flu, it is recommended to ease into the keto diet gradually rather than abruptly cutting out carbohydrates.
• Stay well-hydrated by drinking plenty of water. The keto diet can cause dehydration due to the rapid loss of water weight.
• Replace electrolytes such as sodium, potassium, and magnesium, which can be lost during the keto diet. Include salty foods and electrolyte-rich foods like leafy greens and avocados in your diet.
• Get plenty of rest and avoid strenuous exercise during the initial phase of the keto diet. Light exercises like yoga or walking may be beneficial.
• Ensure you are consuming enough healthy fats and calories. Do not restrict your calorie intake too much, especially during the transition phase.
• If symptoms persist or become severe, consult a healthcare professional. The keto diet may not be suitable for everyone, and it is essential to consider individual health needs and conditions.

In conclusion, while the keto diet has gained popularity for weight loss and health improvement, it is important to be aware of the potential side effects, such as the keto flu. By understanding the keto flu, taking preventive measures, and managing symptoms effectively, you can increase your chances of a smoother transition into the keto diet.
