Keto Flu: Why You're Not Sick

The keto flu is a collection of symptoms experienced by some people 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. However, not everyone experiences the keto flu. The reason some people adapt to ketogenic diets easier than others is unknown, but genetics, overall health, nutrient deficiencies, age, activity level, sleep, stress, and genetics are believed to be the driving forces behind the keto flu.

The keto flu is a result of your body adjusting to a new fuel source

The keto flu is a collection of symptoms that some people may experience when starting 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. Normally, fat is a secondary fuel source that the body uses when glucose is not available. This switch to burning fat for energy is called ketosis.

In a ketogenic diet, carbohydrates are typically reduced to 20 to 50 grams per day. This drastic reduction can shock the body and cause withdrawal-like symptoms, similar to those experienced when weaning off an addictive substance like caffeine.

The keto flu is a term used to describe flu-like symptoms associated with beginning a very low-carb ketogenic diet. Switching to a very low-carb diet is a major change, and your body may need time to adapt to this new way of eating. For some people, this transition period can be especially difficult.

Signs of the keto flu may start within the first few days of cutting back on carbs. Symptoms can range from mild to severe and vary from person to person. While some people may transition to a ketogenic diet without any side effects, others report symptoms such as stomach pain, intestinal pain, diarrhea, fatigue, muscle soreness, and cravings.

The keto flu can be managed by staying hydrated, replacing lost electrolytes, getting enough rest, and ensuring you are consuming proper amounts of fat and carbohydrates.

Carb withdrawal is what makes you feel miserable

The keto flu is a collection of symptoms that some people experience when starting a ketogenic diet. The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein. This diet 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.

The keto flu is a term used to describe flu-like symptoms associated with beginning a very low-carb ketogenic diet. This drastic reduction 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 symptoms of keto flu include headache, brain fog, fatigue, irritability, nausea, difficulty sleeping, and constipation.

The reason some people experience the keto flu is believed to be due to carbohydrate withdrawal. Carbohydrate withdrawal can cause cravings for carbs, as well as a period of discomfort that can last a few days to several weeks. This discomfort can include physical and mental symptoms such as feeling shaky or jittery, as well as strong psychological cravings for high-carb foods.

To ease the symptoms of carb withdrawal, it is recommended to focus on consuming fiber and fat together, as this produces a high degree of satiety. It is also important to stay hydrated, as dehydration can be a factor in the keto flu. In addition, adding electrolytes like salts, potassium, and magnesium to your diet can help stop cramps and nausea.

While the keto flu can make you feel miserable, there are ways to reduce its symptoms and help your body get through the transition period more easily.

Genetics, electrolyte loss, dehydration and carbohydrate withdrawal are believed to be the driving forces behind the keto flu

The keto flu is a collection of symptoms that some people experience when starting a ketogenic diet. The symptoms, which can feel similar to the flu, are caused by the body adapting to a new diet that consists of very few carbohydrates. The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein.

Genetics, electrolyte loss, dehydration, and carbohydrate withdrawal are believed to be the driving forces behind the keto flu. Firstly, genetics may play a role, as some people are naturally "metabolically flexible," meaning they can shift metabolic states easily without experiencing health symptoms. Secondly, electrolyte loss can occur due to the decrease in insulin levels that happens when following a ketogenic diet. This can lead to an imbalance of important nutrients like sodium, potassium, and magnesium, which can cause various symptoms. Thirdly, dehydration can be a factor, as a keto diet can cause a rapid loss of water stores in the body, which can exacerbate symptoms such as fatigue and muscle cramping. Finally, carbohydrate withdrawal can be a significant contributor to the keto flu. The drastic reduction in carbohydrates can come as a shock to the body and may trigger withdrawal-like symptoms, similar to those experienced when weaning off addictive substances.

To manage keto flu symptoms, it is recommended to stay hydrated, replace lost electrolytes, get enough rest, avoid strenuous activities, and gradually reduce carbohydrate intake over time.

Symptoms can last from a few days to several weeks

The keto flu is a collection of symptoms that some people experience when starting a ketogenic diet. It is important to note that this is not an actual flu, nor is it contagious or dangerous. However, the symptoms can be very unpleasant and may last from a few days to several weeks.

The ketogenic diet is a very low-carbohydrate, high-fat, and moderate-protein diet that has gained popularity for weight loss and potential health improvements. When starting this diet, some people may experience a range of symptoms, including stomach or intestinal pain, diarrhea, fatigue, muscle soreness, and cravings, among others. These symptoms are the body's response to entering ketosis, a metabolic state where the body burns fat for energy instead of carbohydrates.

The duration of the keto flu varies from person to person. For some, the symptoms may last only a few days, while others may experience them for up to several weeks or even a month. The average duration is about a week. The severity and duration of the keto flu also depend on individual factors such as genetics, with some people being naturally "metabolically flexible" and able to shift metabolic states easily.

To manage the keto flu, it is recommended to ease into the ketogenic diet gradually, staying well-hydrated, consuming enough electrolytes, getting plenty of rest, and including more healthy fats in the diet. Light exercise may also help relieve muscle pain and tension.

Staying hydrated and increasing salt and water intake can help alleviate symptoms

Staying hydrated is a crucial part of managing keto flu symptoms. When you restrict carbohydrates, your body produces less insulin, causing your kidneys to flush out excess water and sodium. This can lead to dehydration, which can cause symptoms such as fatigue, dizziness, and headaches.

To combat this, it is recommended to increase your water intake. Aim for a minimum of 2.5 litres of fluid every day during the first week of your keto diet. You can also try drinking a glass of water with half a teaspoon of salt stirred into it, as the loss of salt is also responsible for many keto flu symptoms. This can include nausea, constipation, and muscle cramps.

In addition to water, it is important to replenish electrolytes, particularly sodium, potassium, and magnesium. These can be obtained through diet or supplements. Sodium-rich foods include salted nuts, pickles, and bone broth. For magnesium, try eating seaweed, seeds, nuts, avocados, and leafy greens. Potassium can be found in avocados, spinach, broccoli, mushrooms, and lean meats.

By staying hydrated and increasing your salt and water intake, you can effectively manage and alleviate many of the symptoms associated with keto flu.
