The Keto Flu: What it is and What You Can do?

Last Updated on July 13, 2018 by Paula

You felt so good starting the keto diet.

You behaved, never cheated, then bam!

You feel like you are going to have the flu!

What is happening???

One of the most common questions people like me starting on the keto diet ask is why you feel like sh*t .

Well, you must have the keto flu.

Keto flu is what happens when you start keto and suddenly have symptoms that are like the flu.

But here is the good news!  You can avoid keto flu.

And, if you will have it while on keto, it is very easy to treat

Craving for spaghetti but you are on the keto diet? Try this Skinny Noodles Shirataki Spaghetti. I get my 12 packs at around only $30!

Here are some things to know about the keto flu.

What is the Keto Flu?


The keto flu is not a real medical condition.

It is a term people on keto coined for experiencing a combination of symptoms similar to flu.

Keto flu occurs when you enter ketosis while you are on the keto diet if you are low on electrolytes.

This will often create some physical and mental symptoms that are similar to what you experience when you have the flu, which is where the name comes from. The keto flu does not last long and can be remedied simply by replenishing your electrolytes.

However, it can be hard to get through especially in the beginning when you are adjusting to being on the keto diet.

Products I love when it comes to electrolyte replenishment:

How do you Know you Have Keto Flu?

If you ever had the real flu, then that is quite similar to keto flu.

You may feel lightheaded, dizzy, with body aches, a major headache, your body aches, and heck, you are irritable people will think you are PMSing.

What To Do When You Have Keto Flu?

The fastest way to get rid of the keto flu is to replenish your electrolytes, as this is most often the cause.

This is because being on keto makes you want to pee a lot of times.  This may make you lose electrolytes.

In addition, in your new diet, you may not be getting enough salt and potassium.

Our body needs three main electrolytes – sodium, potassium, and magnesium.

You can get sodium through salt; potassium through veggies and avocados.  For magnesium, I love taking this:

Try to make electrolyte water.

Try making electrolyte water by adding some pink salt and lite salt to a tall glass of water. This not only helps treat keto flu, but drinking it daily can keep you from experiencing these symptoms again in the future.
