What Is Induction Flu?

While the Keto diet is considered safe for most people, it does have side effects. One of the most common after-effects that a keto dieter experiences during the first week are of ‘induction flu’. Also termed as the ‘keto flu’ or the ‘carb flu,’ it carries symptoms that mimic flu. 

Induction flu or keto flu is a term used to describe various short term symptoms like fatigue, headaches, nausea, etc people experience on a keto diet as a result of their body being in ketosis. Ketosis is a metabolic state that is kicked by a very low-carb diet, wherein, your body starts to burn fats as a primary energy source, instead of carbs (sugars). The burning of those extra fats helps you burn those extra kilos. The keto diet thus helps in rapid weight loss. But what exactly causes the induction flu? The next section helps you with that.

What Causes Induction Flu?

The symptoms of induction flu or keto flu are primarily caused by the body getting habituated to a new diet comprising of very less amount of carbohydrates.A reduction in carb consumption compels your body to burn ketones for energy rather than glucose. This process of transition is called ketosis.

However, the stage of ketosis can be reached by endorsing a low carb diet. In a ketogenic diet, the carb intake is decreased to a bare minimum. As a result, dehydration and loss of electrolytes are the main cause.

This forceful curtailment can transport the body into a state of shock and may initiate symptoms, similar to those experienced when weaning off an addictive substance like alcohol.

Is Keto Flu Or Induction Flu A Sign Of Ketoacidosis

On a ketogenic diet, people might experience various symptoms that go away with time. The symptoms, in general, are called the Induction Flu. 

When your body is in the state of ketosis, your liver starts to make ketone bodies or ketones like acetone, acetoacetate, and Betahyroxybutyric acid BHB. Keto flu is caused as a result of ketosis.

In rare conditions, your body might produce too many ketone bodies, causing your blood to be more acidic. This condition is called ketoacidosis and is life-threatening. Ketoacididodis is totally different from ketosis and has nothing to do with keto flu. Keto flu is a temporary short-lived set of symptoms while ketoacidosis is a dangerous metabolic disorder.
