The so-called keto flu is a group of symptoms that may appear two to seven days after starting a ketogenic diet. Headache, foggy brain, fatigue, irritability, nausea, difficulty sleeping, and constipation are just some of the symptoms of this condition, which is not recognized by medicine.
Symptoms of the keto flu are usually mild, begin when a person starts the diet, and may only last a few days to a few weeks. They may ease off when the body enters a state of ketosis. According to one scientific profile of the diet, keto flu can involve the following symptoms: nausea.
Increased focus and energy. People often report brain fog, tiredness and feeling sick when first starting a very low-carb diet. This is termed the “ low carb flu ” or “ keto flu.” However, long-term ketogenic dieters often report increased focus and energy.
You may go through the keto flu again. You may experience ” keto flu ” symptoms again, depending on your metabolism and what kind of keto break you took. You might also have headaches, nausea, fatigue, stomach pain and body aches, brain fog, and mood swings.

When a person is in nutritional ketosis, they will have blood ketone levels of 0.5–3 millimoles per liter.

You ‘ll Feel Sluggish and Tired in the First Two Weeks of Keto ( Keto Flu ) The infamous Keto Flu. Many people feel sluggish, tired, and weak when transitioning to a Keto diet. It’s because your body is used to running on carbs and you ‘ve taken that fuel source away.
How Long Does the Keto Flu Last? Symptoms of the keto flu generally begin within the first day or two of removing carbs. For an average person, the keto flu can last a week or less but in extreme cases the keto flu can last up to a month. However, depending on your genetics, you may never experience the keto flu.
First of all, you can drink alcohol and stay in ketosis. But there’s a catch. Though one glass of something strong won’t knock your body out of ketosis, drinking alcohol while following a keto diet will affect your progress. Specifically, it will slow down your rate of ketosis.

When the body excretes these in urine, they can make the urine smell like popcorn. A high level of ketones in the urine or blood is called ketosis. The body will produce ketones when it does not have enough sugar or glucose for fuel. This might happen overnight or when a person is fasting.

At this point, the body will start to break down protein and fat to get energy. This metabolic process is called ketosis.
But if you don’t get enough fat and aren’t in ketosis because you eat too much protein, you could leave the body in a state of energy limbo. “ If protein and carbohydrate intake is not managed, the person on a ketogenic diet may not go into ketosis and may just feel completely deprived and hungry,” Shapiro said.
