As Keto Diet is enjoying great popularity among the diet plans, I feel that we should allow the same interest to the KETO FLU SYMPTOMS AND TREATMENT. Let’s start by defining the term of keto flu.

If we were to define the KETO FLU, we could say that it is a collection of symptoms associated with our body in the attempt to adapt to the ketogenic diet. The symptoms may appear between two to seven days after starting the Keto Diet.

While a search for this term will lead you to not a single result on PubMed, the library of indexed medical research journals, an internet search will result in thousands of blogs and articles about the so-called keto flu.
