The keto flu is a collection of symptoms experienced by some people when they first start the keto diet.These symptoms, which can feel similar to the flu, are caused by the body adapting to a new diet consisting of very little carbohydrates (Kubala, 2018).
The symptoms of keto flu can range from mild to severe and may vary depending on the person’s overall health condition and body adjustments. While some may shift to keto diet without feeling any side effect, others have experience one or more of these symptoms:
- Light vomiting
- Muscle cramps
- Poor concentration
- Stomach pain
- Muscle soreness
- Difficulty sleeping
- Sugar cravings
These symptoms are commonly reported by those who have just begun the ketogenic diet and can be distressing. They also typically last about a week, though some people may experience them for a longer period of time (Kubala, 2018).
Overall, ketogenic diet is mainly described as a good diet with several health benefits aside from the normal weight loss. For first timers, there may be some body adjustments that will happen during the initial stage (keto flu) but everything is bearable and can be surpasses if the diet is taken seriously.
