Keto Flu: A Recurring Battle For Dieters?

The keto flu is a collection 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 symptoms such as headache, fatigue, nausea, and constipation. These symptoms are caused by the body adapting to a new diet consisting of very few carbohydrates. They usually appear within the first few days of starting the diet and can last from a few days to several weeks. While the keto flu can be unpleasant, it is usually temporary, and there are steps that can be taken to reduce its symptoms, such as staying hydrated, replacing electrolytes, and getting enough rest.

Keto flu symptoms

The keto flu is a collection of symptoms that some people experience 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 that is very low in carbohydrates. The symptoms can be mild or severe and usually last a few days but can last up to several weeks.

Some common symptoms of keto flu include:

• Diarrhea or constipation
• Stomach or intestinal pain
• Nausea
• Headaches
• Fatigue
• Muscle soreness and cramps
• Irritability
• Dizziness
• Sugar cravings
• Trouble falling or staying asleep
• Poor focus and concentration
• Brain fog

The keto flu is believed to be caused by a combination of factors, including genetics, electrolyte loss, dehydration, and carbohydrate withdrawal. The drastic reduction in carbohydrate intake can be a shock to the body, leading to withdrawal-like symptoms.

It is important to note that the keto flu is usually temporary, and there are ways to reduce the symptoms. Staying hydrated, replacing lost electrolytes, getting enough rest, ensuring sufficient fat intake, and gradually reducing carbohydrate consumption can help alleviate the discomfort associated with the keto flu.

Causes of keto flu

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. Reducing your carb intake forces your 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. This switch to burning fat for energy is called ketosis.

The keto flu is caused by the body's transition to ketosis. The drastic reduction in carbohydrates can be a shock to the body and may cause withdrawal-like symptoms, similar to those experienced when weaning off an addictive substance like caffeine. The keto flu is believed to be driven by genetics, electrolyte loss, dehydration, and carbohydrate withdrawal.

The symptoms of keto flu usually appear within the first few days of starting the diet and can range from mild to severe. Symptoms can include diarrhea, constipation, fatigue, muscle soreness, cravings, headaches, and trouble sleeping.

While the keto flu can be unpleasant, it is usually temporary, and there are ways to reduce the symptoms. Staying hydrated, replacing lost electrolytes, getting enough rest, and ensuring adequate consumption of fat and carbohydrates can help reduce the symptoms of keto flu.

How to prevent keto flu

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

• Transition gradually: Cut back on carbs slowly while increasing the amount of fat and protein in your diet. This can help you ease into the keto diet and make the transition smoother. Eating more fat can also help reduce cravings for foods you'll need to avoid on the diet, such as bread and pasta.
• Stay hydrated: Drink plenty of water as the keto diet can quickly deplete your water stores, putting you at risk of dehydration and electrolyte imbalances.
• Adjust your workout routine: Avoid strenuous exercise and focus on lighter activities such as walking or yoga.
• Moderate caffeine intake: Cut back on caffeine as it can negatively impact your sleep. It's not uncommon for people with keto flu to have trouble sleeping.
• Eat more: Make sure you're eating enough fat and calories. Remember, the primary fuel source on a keto diet is fat, so you need to add enough to keep you satisfied and help your body adapt to burning fat for fuel.

How to treat keto flu

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. The symptoms can include fatigue, muscle soreness, headaches, nausea, and constipation, and can last from a few days to a few weeks.

• Stay hydrated: Drink plenty of water to prevent dehydration, as the keto diet can cause a rapid loss of water stores. Aim for a minimum of 2.5 litres of fluid per day during the first week of the keto diet.
• Replace electrolytes: The keto diet can lead to a loss of electrolytes, so add more salt to your food or drink sports drinks or bone broth to replace electrolytes like sodium, potassium, and magnesium.
• Eat more healthy fats: Increase your intake of healthy fats like olive oil, avocado, and egg yolks. This will help reduce cravings and keep you feeling satisfied.
• Get plenty of rest: Take it easy during the first week of the keto diet, and avoid strenuous exercise. Light activities like walking or yoga may help improve symptoms.
• Gradual transition: If possible, transition to the keto diet gradually by first reducing your carb intake over a few days or weeks, rather than all at once. This can help your body adjust to the new diet without the negative symptoms of the keto flu.
• Take supplements: Consider taking vitamin and mineral supplements to prevent deficiencies, especially if you're on the keto diet for an extended period.
• Eat more frequently: Eat smaller meals more often to ensure you're getting enough calories and nutrients. Include plenty of colourful vegetables in your diet.

When to see a doctor about keto flu

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. It is caused by the body adapting to a new diet consisting of very few carbohydrates. Symptoms can include fatigue, muscle soreness, nausea, and constipation. While the keto flu is usually temporary and rarely requires medical attention, there are some instances in which you should see a doctor.

Firstly, if your symptoms don't improve after a couple of weeks, or if they are particularly intense or debilitating, it may be time to consult a medical professional. Additionally, if you are experiencing a fever, prolonged diarrhea, or vomiting, it is best to contact your doctor to rule out other causes.

Keto flu symptoms can also be confused with more serious problems, such as stomach issues or nutritional deficiencies. Your doctor can help determine if your symptoms are indicative of a more severe condition or if adjustments to your diet are necessary.

Finally, while the keto diet is generally considered safe for most people, it may not be suitable for everyone. For example, pregnant or breastfeeding individuals, children, and teens should only attempt the keto diet under medical supervision. If you fall into one of these categories, be sure to consult your doctor before starting the diet.
