The idea (and sound) of a flu freaks most people out. Honestly, I reacted the same way at first. ...yeah, I kinda hate the flu.
But it’s not the actual flu. *sigh of relief*
Keto flu may happen when transitioning to keto. It usually goes away in just a few days and can be eliminated completely but if you don't get in the right amount of electrolytes it can linger around longer.
Here's why it happens:
Carbs usually contains lots of electrolytes.
Because keto switches your body's fuel source from carbs to fats you won't consume as many electrolytes as before. And plus you will urinate more on keto which means less electrolytes and water in your body.
Thus, the lack of electrolytes can affect you.
In addition, when you transition from a high to low carb diet your body will need to create new enzymes.
All of this can cause symptoms of a flu like lower energy, brain fog, fatigue, and the like.
But you can avoid it altogether if you get in enough electrolytes. Electrolytes are a MUST!
