Keto Flu: Understanding The Timing And Symptoms

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 keto flu can start within the first few days of cutting back on carbs, and symptoms can last from a few days to several weeks. The symptoms include fatigue, headache, irritability, constipation, and nausea. To alleviate the symptoms, it is recommended to drink plenty of water, eat more salt, and get plenty of rest.

Flu-like symptoms

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 diet aims to put the body in a state of ketosis, where it burns stored fat instead of glucose for energy.

The keto flu is so-called because its symptoms can feel similar to the flu. These symptoms are caused by the body adapting to a new diet consisting of very few carbohydrates. The symptoms of keto flu can include:

• Fatigue
• Headaches
• Irritability
• Insomnia
• Constipation or diarrhea
• Nausea
• Muscle aches and soreness
• Sugar cravings
• Poor focus and concentration
• Dizziness

The keto flu can start within the first few days of cutting back on carbs and usually lasts for a few days to a few weeks. In extreme cases, it can last up to a month.

The keto flu is generally not a cause for concern and can be managed with home remedies. Staying hydrated and replacing lost electrolytes are important ways to reduce the symptoms of keto flu. Getting plenty of rest and avoiding strenuous activities can also help. In addition, making sure to eat enough healthy fats and carbohydrates can ease the transition to a ketogenic diet.

Dehydration

Drinking enough water is necessary for optimal health and can also help reduce symptoms of dehydration. However, drinking too much sodium-free water on the keto diet can actually make dehydration worse. This is because over-hydrating dilutes blood sodium levels, which can cause keto flu symptoms such as confusion, lethargy, headaches, and cramps.

To avoid dehydration, it is recommended that you drink enough electrolytes, such as salts, potassium, and magnesium, in addition to water. Drinking sports drinks or taking supplements can help with this.

Electrolyte imbalance

The keto flu is a collection of symptoms experienced by some people when they first start a ketogenic diet. This is the body's response to entering ketosis, which can often mimic flu symptoms.

One of the most common causes of keto flu is an electrolyte imbalance. Electrolytes are minerals that carry an electric charge, and they are vital for the proper functioning of your body. Electrolyte imbalances can cause a range of problems, from headaches to muscle cramps and even convulsions.

When you transition to a keto diet, you may get low on electrolytes due to carb restriction leading to lower insulin levels. Insulin is an important hormone that helps the body absorb glucose from the bloodstream. When insulin levels decrease, 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.

Eat Whole Foods Rich in Electrolytes:

Eat more whole foods that are high in electrolytes, such as spinach, avocados, beef, chicken, eggs, clams, salmon, lettuce, tomatoes, yogurt, and almonds.

Obtain Electrolytes with Keto-Friendly Supplements:

Consuming an electrolyte drink is a convenient way to get electrolytes no matter the time and place. Stick to sugar-free and keto-friendly options, such as electrolyte powders that you can add to water.

Pay Attention to Your Thirst:

Thirst is a sign of mild dehydration, which can make you feel tired and dizzy. Address thirst immediately by drinking water or an electrolyte drink. As you age, your sense of thirst diminishes, so older people should be especially mindful of staying hydrated.

Transition Slowly into the Keto Diet:

You don't have to go cold turkey with the keto diet. It's okay to start slowly and ease into it. Try doing low-carb first, eating up to 150 grams of carbs per day for a week before going full keto.

Consult with Your Doctor:

If you're taking medications, talk to your doctor before starting the keto diet, as certain medications can affect your electrolyte levels. It's also important to work with a doctor who has experience assisting patients with a low-carb or keto lifestyle.

Carb withdrawal

The body's default energy source is carbohydrates (glucose), so switching to a fat-burning process can be confusing for the body. When the body is depleted of stored glucose, it turns to burning fatty acids for energy, which is the metabolic process of ketosis. This drastic reduction in carbohydrates can come as a shock to the body, and may cause withdrawal-like symptoms, similar to those experienced when withdrawing from an addictive substance like caffeine.

The keto flu can last a week or less for the average person, but in extreme cases, it can last up to a month. 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
• Headaches
• Fatigue

To manage the symptoms of keto flu, it is recommended to:

• Drink plenty of water
• Take an electrolyte supplement
• Consume enough healthy fats
• Get plenty of rest
• Try light exercise
• Ease into the ketogenic diet gradually

Diet transition

The keto flu is a collection of symptoms experienced by some people when they first start the keto diet. Symptoms can start appearing within the first few days of cutting back on carbs, and they can last a few days or up to several weeks.

The keto flu is caused by the body adapting to a new diet consisting of very few carbohydrates. This forces the body to burn ketones for energy instead of glucose. Normally, fat is reserved as a secondary fuel source to use when glucose is not available. This switch to burning fat for energy is called ketosis.

• Ease into the diet: Start with a typical low-carb diet and give your body time to adjust. Try that for a week, and then you can go fully into the keto diet.
• Stay hydrated: A keto diet can cause you to rapidly shed water stores, increasing the risk of dehydration. Drink plenty of water to prevent this.
• Replace electrolytes: When following a ketogenic diet, insulin levels decrease, causing the kidneys to release excess sodium from the body. Include potassium-rich, keto-friendly foods like green leafy vegetables and avocados in your diet.
• Get enough 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 your mood and make keto-flu symptoms worse.
• Avoid strenuous exercise: While exercise is important for staying healthy, strenuous exercise should be avoided when experiencing keto-flu symptoms. Light activities like walking, yoga, or leisurely biking may improve symptoms.
• Eat enough fat: Eating enough fat, the primary fuel source on the ketogenic diet, will help reduce cravings and keep you feeling satisfied.
• Cut out carbs slowly: If you're having a difficult time adapting to the ketogenic diet, you may need to eliminate carbohydrates gradually rather than all at once. Slowly cutting back on carbs while increasing fat and protein in your diet may help make the transition smoother and decrease keto-flu symptoms.
