Keto Flu And Hangovers: What's The Real Difference?

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. The ketogenic diet is a very low-carbohydrate, high-fat, and moderate-protein diet that has gained popularity for weight loss and its potential health benefits. The keto flu is not an actual flu, nor is it contagious or dangerous, but it can be very unpleasant. Symptoms include fatigue, nausea, headaches, muscle soreness, and sugar cravings, among others. These symptoms are the result of the body adapting to a new diet and can range from mild to severe. The good news is that there are ways to manage and reduce the symptoms of keto flu, and they usually disappear within a few days to weeks.

Keto flu symptoms

The keto flu is a collection of symptoms that some people may experience when they start a ketogenic diet. It is important to note that this is not an actual flu, nor is it contagious or dangerous. The symptoms arise as the body gets used to operating with fewer carbohydrates and as it enters a state of ketosis, burning fat for energy instead of glucose.

The symptoms of keto flu can range from mild to severe and usually last a few days but can last up to several weeks in some cases. Some of the most frequently reported symptoms include:

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

The keto flu can be managed or prevented by:

• Staying hydrated: Drinking plenty of water can help reduce symptoms such as fatigue and boost energy levels.
• Replacing electrolytes: Adding electrolytes like salts, potassium, and magnesium to your diet can help with cramps and nausea.
• Getting plenty of rest: Taking an Epsom salt bath can help soothe and relax muscles and improve sleep.
• Trying light exercise: Light activities such as yoga can help relieve muscle pain and tension and boost your mood.
• Transitioning gradually: Slowly cutting back on carbs while increasing the amount of fat and protein can help ease the transition.

While the keto flu can be unpleasant, the symptoms are usually temporary, and there are steps you can take to reduce their impact.

Causes of keto flu

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. 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 keto flu is essentially the body experiencing symptoms of withdrawal from carbohydrates. The body usually burns carbohydrates (glucose) for energy, so switching to a fat-burning process can be confusing for the body. When the body does not take in enough carbohydrates to use for energy, the liver begins to produce glucose for energy, using its stores. This process is called glucogenesis.

Eventually, the liver will not be able to produce enough glucose to keep up with the body's energy demands, and the body will start breaking down fatty acids, which will produce ketone bodies. This process is called ketogenesis, and it leads to the body entering a state of ketosis.

The symptoms of keto flu are caused by temporary imbalances in energy sources, insulin, and minerals in the body. The lack of carbohydrates decreases insulin in the bloodstream, leading to an increase in the amount of sodium, potassium, and water released in the urine, which can cause dehydration. Insulin is also involved in transporting glucose to the brain, so before the brain starts using ketones for energy, it will have less fuel, which can cause symptoms such as brain fog and fatigue.

The symptoms of keto flu usually appear within the first few days of starting a ketogenic diet and can range from mild to severe. They typically last a few days but can persist for several weeks in some cases.

Some common symptoms of keto flu include:

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

Managing keto flu

The keto flu is a collection of flu-like symptoms some people experience when starting a ketogenic diet. It is caused by the body adapting to a new diet consisting of very few carbohydrates. The good news is that there are several ways to reduce its flu-like symptoms and help your body get through the transition period more easily.

Stay Hydrated

Drinking enough water is necessary for optimal health and can also help reduce keto flu symptoms. A keto diet can cause you to rapidly shed water stores, increasing the risk of dehydration. Staying hydrated can help with symptoms like fatigue, muscle cramping, and headaches.

Replace Electrolytes

When following a ketogenic diet, levels of insulin decrease, and the kidneys release excess sodium from the body. The keto diet also restricts many foods that are high in potassium, including fruits, beans, and starchy vegetables. Salting food to taste and including potassium-rich, keto-friendly foods like leafy greens and avocados are excellent ways to ensure you are maintaining a healthy balance of electrolytes.

Get Plenty of Rest

Fatigue and irritability are common complaints of people adapting to a ketogenic diet. Lack of sleep causes levels of the stress hormone cortisol to rise in the body, which can negatively impact mood and make keto-flu symptoms worse. Make sleep a priority during this time to help combat zapped energy levels.

Eat Keto-Friendly Foods

When hungry, try eating more healthy keto-approved foods to help satisfy your cravings. Eating an overwhelming number of calories more than what you burn will likely still lead to weight gain, regardless of whether or not you've gone keto. However, you may feel particularly hungry and have strong cravings for carbohydrates when you first begin the ketogenic diet.

Take it Slow

If none of the above suggestions calm your keto flu woes, consider a more scaled approach to keto dieting. This means slightly increasing your carb intake to give your body more time to adapt to using more fat for fuel. Start with a more moderate approach and then gradually cut back on carbohydrates while increasing fat and protein in your diet.

Duration of keto flu

The keto flu is a collection of symptoms that some people experience when starting a ketogenic diet. It is important to note that the 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 that is very low in carbohydrates. The drastic reduction in carbohydrates can be a shock to the body, and some people may find the transition period especially challenging.

The symptoms of keto flu can begin within the first few days of cutting back on carbs, typically within the first day or two. For most people, the keto flu lasts about a week or less. However, in some extreme cases, it can last up to a month. The symptoms will usually gradually decrease as your body gets used to converting ketones into energy.

The duration of the keto flu can vary depending on individual factors, such as genetics. Some people may never experience the keto flu at all. These individuals are considered "metabolically flexible," meaning they can easily shift between metabolic states without experiencing negative health symptoms.

If you are experiencing keto flu, it is important to stay hydrated, replace lost electrolytes, get enough rest, and ensure you are consuming adequate amounts of healthy fats and calories. Gradually reducing your carbohydrate intake over a few days or weeks can also help to ease the transition and reduce the duration of the keto flu.

Keto flu vs ketoacidosis

Keto flu and ketoacidosis are two distinct conditions that can occur when the body is in a state of ketosis, but they have very different effects on the body and require different levels of medical attention.

Keto Flu

Keto flu is a term used to describe the collection of symptoms that some people experience when they first start a ketogenic diet. These symptoms can include fatigue, dizziness, nausea, headaches, insomnia, and gastrointestinal issues. The keto flu is generally not serious and typically resolves on its own within a few days to a few weeks. Increasing water intake and getting plenty of electrolytes can help alleviate the symptoms.

Ketoacidosis

Ketoacidosis, on the other hand, is a much more serious condition that can be life-threatening if left untreated. It is a complication of diabetes, usually type 1, but it can also occur in people with type 2 diabetes or in rare cases, in non-diabetics. Ketoacidosis occurs when the body produces extremely high levels of ketones, making the blood too acidic. This is often due to a lack of insulin, which is needed to move glucose from the blood into cells for energy. Symptoms of ketoacidosis include high blood glucose levels, high levels of ketones in the urine, thirst, frequent urination, fruity-smelling breath, confusion, and loss of consciousness. Ketoacidosis is a medical emergency that requires immediate treatment, typically involving intravenous fluids, insulin therapy, and electrolyte replacement in a hospital setting.

Key Differences

While both keto flu and ketoacidosis can cause similar symptoms such as fatigue and nausea, the underlying causes are different. Keto flu is a temporary condition that usually resolves on its own and is not life-threatening. It is typically experienced by people who are starting a ketogenic diet. On the other hand, ketoacidosis is a serious complication of diabetes that arises from a lack of insulin and can be fatal if left untreated. Ketoacidosis requires immediate medical attention and hospitalization.
