What You Need to Know About the Keto Flu

Keto Flu is a real thing, and it has become a common occurrence for those looking to adopt the ketogenic diet. This unpleasant experience can be characterized by symptoms like headaches, nausea, and muscle cramps. But does it have to be this way?

The reality is that anyone beginning the keto diet should expect to experience some level of Keto Flu. This happens because the body needs time to switch from its normal metabolism of glucose-based energy sources to fat-based energy sources while in a state of ketosis. Fortunately, there are ways to ease into the transition when starting out on the keto diet which can reduce or even eliminate the uncomfortable side effects associated with Keto Flu.

Common Uncomfortable Effects

The ketogenic diet has become increasingly popular in recent years as it is known to help with weight loss, but many people don’t realize the uncomfortable effects that often accompany this type of eating.

The “keto flu” is a term used to describe the symptoms some individuals may experience when transitioning from a higher-carbohydrate diet to a low-carb, high-fat diet. Symptoms can range from feeling lethargic and low on energy, to headaches, nausea, brain fog and difficulty sleeping. These symptoms are usually caused by the body’s sudden lack of carbohydrates which can lead to dehydration and electrolyte imbalances.

Fortunately, there are ways to relieve these symptoms so you can get back to enjoying your ketogenic lifestyle.

Low Carb Diet Transition

Starting a low-carb diet can have some unpleasant side effects. The so-called “keto flu” is one of the most common symptoms when transitioning to this type of eating plan. The keto flu can cause fatigue, headaches, irritability and difficulty concentrating. To better understand what causes this transition period and what you can do about it, read on for all the facts about the keto flu.

The transition period to a low-carb diet is typically caused by your body adjusting to its new fuel source – fat instead of carbohydrates. When cutting out carbs like bread, pasta and sweets, your body needs time to switch from burning sugar as fuel to burning fat instead. During this adjustment period, you may experience the keto flu which is usually characterized by fatigue, headaches, brain fog and difficulty concentrating.

Restore Health

Hydration and Sleep: Restore Health

Are you feeling fatigued, irritable, and just plain “off”? You may be suffering from a condition known as the “keto flu.” This occurs when individuals make the switch to a low- carb diet which can cause electrolyte imbalances in their body. To restore your health, it is important to focus on hydration and sleep.

By replenishing your body with plenty of fluids, you will be able to maintain balanced electrolytes which can reduce symptoms of fatigue and headache associated with the keto flu. Drinking 8-10 glasses of water per day is essential for proper hydration. Additionally, adding sodium or potassium rich food such as olives or avocados can help restore balance while consuming meals low in carbohydrates.


The ketogenic diet can be a great way to jumpstart your weight loss journey and overall health. But, like any lifestyle change, it’s not without its drawbacks. One of the most significant side effects is something known as the “keto flu,” which can occur when the body transitions from burning carbs to fat for energy.

So how do you prepare yourself? The best way to avoid or minimize the effects of the keto flu is by taking it slow and steady. Gradually reduce carbohydrates over time, rather than cutting them out all at once. Increase your intake of electrolytes such as potassium and magnesium through food sources or supplements if necessary; these minerals play an important role in maintaining adequate hydration levels, helping your muscles function properly, and balancing blood sugar levels during this transition period.

Start by reducing your carb intake by a small amount, and begin transitioning to more fat-burning foods such as eggs, fish, and meat.
