The ketogenic diet is a very low-carb, high-fat, and high-protein diet that aims to put the body in a state of ketosis, where it burns stored fat instead of glucose for energy. While ketosis is considered safe for most people, the transition into this state can cause a range of side effects, including nausea, fatigue, headaches, abdominal pain, and vomiting—a set of symptoms commonly referred to as the keto flu. This is because the body is withdrawing from carbohydrates, its preferred energy source, and the sudden increase in fat consumption takes a long time to digest and absorb. The keto flu typically lasts for a week or less, but in extreme cases, it can persist for up to a month.

Keto flu
The ketogenic diet is a popular way to lose weight and potentially improve health. The diet is very low in carbohydrates, high in fat, and moderate in protein. While it is considered safe for most people, it is associated with some unpleasant initial side effects. This collection of symptoms is commonly referred to as the "keto flu" or "carb flu".
The keto flu is a set of symptoms that people may experience when they start the keto diet. These symptoms are usually minor and short-term, lasting between a few days and a few weeks. They arise as the body gets used to operating with fewer carbohydrates and as it enters a state of ketosis. The symptoms include nausea, vomiting, abdominal pain, headaches, fatigue, dizziness, sugar cravings, muscle soreness, irritability, diarrhoea or constipation, trouble sleeping, poor focus and concentration, and brain fog.
The keto flu can be prevented or mitigated by staying hydrated, eating more frequently, and consuming plenty of colourful vegetables. It is also recommended to ease into the diet slowly, rather than stopping carbohydrates cold turkey. Additionally, light exercise, such as walking, yoga, or leisurely biking, may help improve symptoms.
It is important to note that the keto diet is not safe for everyone and can cause serious complications. It is always a good idea to consult a doctor before starting the keto diet to ensure that it is safe for you. Doctors should also frequently monitor cholesterol and fat levels for people on the keto diet, as it can cause an increase in cholesterol levels.

Carbohydrate withdrawal
The ketogenic diet is very low in carbohydrates, high in fat, and moderate in protein. The diet aims to reduce the insulin response through excessive carbohydrate restriction. However, reducing insulin causes an increase in circulating fats that displace tryptophan, an amino acid, from its carrier. This increase in circulating tryptophan causes a rise in serotonin in the brain, resulting in fatigue. The lack of carbohydrates also stimulates the release of cortisol, a stress hormone, and the amount released depends on the size of the stressor.
Symptoms of carbohydrate withdrawal include nausea, fatigue, headaches, muscle cramps, bad breath, weakness, constipation or diarrhoea, and intense cravings for carbohydrates. These symptoms are usually transient, lasting only a short period of time, and are believed to be driven by genetics, electrolyte loss, dehydration, and carbohydrate withdrawal. The symptoms can last from a few days to a few weeks, and typically decrease as the body gets used to converting ketones into energy.
To reduce the symptoms of carbohydrate withdrawal, some people may find it helpful to eliminate carbohydrates gradually rather than all at once. This involves slowly cutting back on carbohydrates while increasing fat and protein intake, which may make the transition smoother and decrease keto-flu symptoms.

High-fat consumption
The ketogenic diet is very low in carbohydrates and high in fat and protein. The intention is to put the body in a state of ketosis, where it burns stored fat instead of glucose for energy. This metabolic process of ketosis can cause nausea due to high-fat consumption.
When eating a conventional diet that includes carbohydrates, glucose increases in the blood. This stimulates a rise in the hormone insulin, which regulates blood sugar levels and allows the body to use glucose for energy. Insulin also suppresses the release of fat particles from fat stores in the body. However, when carb intake is drastically reduced, as in the ketogenic diet, the body is depleted of stored glucose and turns to burning fatty acids for energy. This confuses the body as it burns carbohydrates for energy by default.
Nausea can be caused by consuming high volumes of fat because fat takes a long time to digest and absorb. The ketogenic diet aims to reduce the insulin response through excessive carbohydrate restriction. However, reducing insulin causes an increase in circulating fats. This increase in fats can lead to nausea as the body is overwhelmed by the sudden shift in its primary energy source.
Additionally, the ketogenic diet can cause dehydration, which may contribute to nausea. The lack of carbohydrates decreases insulin in the bloodstream, resulting in increased sodium, potassium, and water release in urine. This loss of water and electrolytes can lead to dehydration, further exacerbating nausea. It is important to ensure adequate hydration and electrolyte intake when following the ketogenic diet.
While the ketogenic diet has potential benefits, such as weight loss and managing certain medical conditions, it is not without its risks. The high-fat consumption associated with the diet can lead to nausea and other side effects, including fatigue, headaches, and abdominal pain. It is essential to consult a doctor before starting the ketogenic diet to ensure it is safe and suitable for the individual.

Dehydration
The risk of dehydration is greater when first starting the ketogenic diet because your body is undergoing a lot of changes in how it handles water and electrolytes. When you start a keto diet, it is normal to lose several pounds of water weight in the first week or two due to glycogen stores being depleted and your body no longer absorbing as much water from carbohydrates. Glycogen holds water in the bloodstream, so when you eliminate glycogen by cutting out carbohydrates, you can easily become dehydrated.
Additionally, a low-carb diet leads the body to produce less insulin. Less insulin in the bloodstream signals the kidneys to excrete sodium at a higher rate. Since sodium helps the body retain water, getting less of it can cause your body to not hang on to as much fluid.
To avoid dehydration, it is recommended to drink plenty of water and other liquids. A general rule of thumb is to drink at least half of your body weight in ounces of water per day. For example, if you weigh 150 pounds, you should drink at least 75 ounces of water per day. Drinking plain water can be challenging, so some tips to increase your water consumption include:
- Keeping a water bottle with you at all times and sipping on it throughout the day
- Setting reminders to drink water every hour
- Infusing your water with fruits or herbs to add flavor
- Drinking water before and after meals
- Avoiding sugary drinks and replacing them with water
It is also important to limit dehydrating foods and drinks such as alcohol, caffeine, and processed foods. Incorporating hydrating foods into your diet can also help maintain proper hydration levels. Leafy greens such as spinach, kale, and lettuce are high in water and electrolytes, while avocados and cucumbers are also hydrating and keto-friendly.

Nutritional deficits
The ketogenic diet is high in fat, particularly saturated fat, and low in polyunsaturated fats and omega-3 fats. It typically includes high amounts of red meat, processed meat, and high-fat dairy. These foods are linked to an increased risk of chronic diseases like CKD, cardiovascular disease, cancer, diabetes, and Alzheimer's disease. The diet is also low in protective foods like vegetables, fruits, legumes, and whole grains, which are associated with a lower risk of these diseases.
The ketogenic diet can be low in thiamin, folate, vitamin A, vitamin E, vitamin B6, calcium, magnesium, iron, and potassium. Low levels of vitamin C, for example, can cause an increased risk of infections. The lack of fiber can cause constipation and disrupt gut microbiota.
The ketogenic diet is often unsustainable because of short- and long-term sugar cravings. It is typically recommended for short-term use, followed by the adoption of healthier eating habits.

Frequently asked questions
Nausea is a common symptom of the "keto flu," which is a set of symptoms that occur when the body enters a state of ketosis. This happens when the body burns fat instead of glucose for energy. The keto flu typically lasts for a week or less but can persist for up to a month in extreme cases.
Other symptoms include vomiting, abdominal pain, headaches, fatigue, constipation, dizziness, sugar cravings, muscle soreness, irritability, and trouble sleeping.
Nausea is caused by consuming high volumes of fat. Fat takes a long time to digest and absorb, leading to an extended feeling of nausea.
To alleviate nausea, ensure adequate hydration and electrolyte intake. Electrolytes like salts, potassium, and magnesium can be added to the diet or supplemented with sports drinks. Additionally, increasing healthy fat consumption can help speed up the transition to burning fat for fuel.
Persistent nausea, especially when accompanied by vomiting and abdominal pain, may require medical attention. Consult a doctor if you are unsure about your symptoms or the suitability of the keto diet for your specific circumstances.
