Keto Flu And Fasting: How Long Does It Last?

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 body's response to entering ketosis can often mimic flu symptoms, hence the name keto flu. Symptoms of the keto flu can include stomach aches, nausea, dizziness, sugar cravings, muscle soreness, irritability, diarrhoea or constipation, trouble sleeping, poor focus, and brain fog. These symptoms typically begin within the first few days of starting a ketogenic diet and can last from a few days to several weeks, and in extreme cases, up to a month.

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 the flu and are caused by the body adapting to a new diet consisting of very few carbohydrates. The symptoms of keto flu can vary from mild to severe and from person to person.

Some of the most common symptoms of keto flu include:

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

The keto flu is not a recognized medical condition, and its exact causes are unknown. However, it is believed to be related to the body's adjustment to a new fuel source, as well as genetics, electrolyte loss, dehydration, and carbohydrate withdrawal.

The symptoms of keto flu typically last for a few days to a few weeks, but in some cases, they can persist for up to a month. The duration of keto flu also depends on individual factors, such as genetics and metabolic flexibility.

How to manage keto flu symptoms

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. Symptoms can include stomach pain, nausea, dizziness, sugar cravings, cramping, muscle soreness, irritability, diarrhoea or constipation, trouble sleeping, poor focus and concentration, and brain fog.

The good news is that there are several ways to manage these symptoms:

• Ease into the keto diet: Rather than going "cold turkey", start with a typical low-carb diet and give your body time to adjust. After a week, you can transition into the full keto diet.
• Stay hydrated: Drinking lots of water can help with keto flu symptoms such as headaches and fatigue. It's easy to work out how much water to drink: just divide your current body weight by two, and that's the minimum number of ounces of water you should drink every day.
• Replace electrolytes: An extremely low-carb keto diet means you cut out some of the richest natural sources of electrolytes, like starchy fruits and vegetables. Add plenty of electrolytes like salts, potassium and magnesium to your diet, or drink sports drinks that are high in electrolytes.
• Eat more healthy fats: It's important to make sure you're getting enough calories when you're on the keto diet. Try snacking on half an avocado, or loading up on egg yolks at dinner.
• Get plenty of rest: Try taking an Epsom salt bath to relax your muscles and improve your electrolyte absorption. You can also try drinking a keto-friendly herbal tea with herbs that calm your nervous system, like chamomile.
• Try light exercise: Light exercise, like restorative yoga, can help to relieve muscle pain and tension, and boost your mood and motivation.

How long keto flu lasts

The keto flu is a collection of symptoms that some people experience when they start a ketogenic diet. The symptoms can include nausea, fatigue, headaches, muscle soreness, dizziness, sugar cravings, and more. These symptoms are the result of the body's transition from burning carbohydrates (glucose) for energy to burning fat, which is called ketosis.

The keto flu can last from a few days to several weeks, and in some extreme cases, the symptoms can last up to a month. The duration of the keto flu depends on the individual, and some people may never experience it at all. The transition to ketosis can be challenging, and it is important to listen to your body and make any dietary changes gradually.

There are several strategies that can help alleviate the symptoms of the keto flu, including staying hydrated, replacing lost electrolytes, getting enough rest, and ensuring adequate calorie intake, especially from healthy fats. It is also recommended to avoid strenuous exercise during this transition period and opt for lighter activities such as yoga or walking.

While the keto flu can be uncomfortable, it is typically temporary and not a cause for concern. However, if the symptoms persist or become severe, it is important to consult a doctor to rule out any other underlying causes.
