Keto flu is basically a collection of symptoms that some people experience when they start the keto diet for the first time. These symptoms feel similar to the flu which are caused by the body trying to adapt to a new diet that consists of very little carbohydrates.

When you reduce your carb intake it forces your body to burn ketones for energy instead of glucose. During the ketogenic diet, ketones, the byproducts of fat breakdown, become the main fuel or the main energy source for the body.

Normally, when glucose is not available the reserved fat acts as a secondary fuel source. This switch of burning fat for energy is called ketosis. This condition basically occurs during specific circumstances that include starvation and fasting.

Nevertheless, ketosis can also be reached by adopting a very low-carb diet. Carbohydrate intake is typically reduced to under 50 grams per day in a ketogenic diet.

This sudden and drastic reduction can come as a shock to the body and may cause withdrawal-like symptoms which is similar to the conditions while weaning off an addictive substance like caffeine.

Symptoms Of Keto Flu

When the body switches to a very low-carb diet it goes under a major change and definitely requires time to adapt to this new way of eating or diet. For some people, this transition period can be quite difficult.

Why do people get Keto Flu?

Generally, different people adapt to ketogenic diets differently. While some people may experience weeks of keto-flu symptoms, others may simply adjust to the new diet with literally no side effects. The symptoms that occur are basically tied to how people’s bodies adjust to the new fuel source.

In general conditions, carbs provide the body with energy in the form of glucose while in the absence of carbs or when the carbs intake is substantially reduced, the body burns ketones from fat instead of glucose.

People who are typically habituated to consume a lot of carbs, especially refined carbs like pasta, soda and sugary cereals may find it more difficult while they begin the ketogenic diet.

Consequently, the transition to high-fat and very low-carb diet may be a difficult task for some while others may be able to switch between fuel sources easily with little to no keto-flu symptoms.

The reason why some people are able to adapt to ketogenic diets more easily than others is still unknown, but genetics, electrolyte loss, carbohydrate withdrawal are believed to be few of the main driving forces behind the keto flu.

Increased Ketones

When you have ketones in the blood that is probably the most definitive sign that the individual is in the ketosis process. More often doctors may also use urine samples and breath tests to check for ketone levels but these are considered less reliable in comparison to the blood samples.

Weight Loss

Individuals on a ketogenic diet may notice weight loss in the first few days but this is generally a reduction in the water weight and the actual fat loss may not occur for several weeks.

Signs Of Ketosis - Weight Loss

Bad Breath

Generally, ketones leave the body through breath and urine thus, people on the keto diet or those around them may notice that the breath smells or fruity. Ketones like acetone, benzophenone and acetophenone are usually responsible for the odour and may contribute to bad breath.

Improved Focus And Concentration

As the insulin levels decrease, the kidneys tend to release excess sodium from the body.

The Keto diet generally restricts many foods that are high in potassium which includes fruits, beans and starchy vegetables. An excellent way to power through the adaptation period of the keto diet is getting adequate amounts of these important nutrients.

When dietary carbohydrates are reduced in the body, glycogen (the stored form of carbohydrates) levels increases as a result water is excreted from the body. So staying hydrated is the only way through which the symptoms like fatigue and muscle cramping can be fought.

When you kind of experience keto-flu-associated diarrhoea, replacing fluids is utmost important as this may cause additional fluid loss.

Get Adequate Sleep

It’s a proven fact that low-carb diets help in reducing cravings for sweets and high-carb foods.

People who are facing a difficult time adapting to the ketogenic diet should eliminate carbohydrates gradually rather than all at once. A gradual process of cutting down carbs while increasing fat and protein in your diet may help in a smoother transition thereby decreasing keto-flu symptoms.
