When I started the Keto diet I definitely went through this period in my adaptation to a fully ketogenic diet. Now with experience on my side I have come to realize I never had to go through this period.

If you properly plan and prepare prior you will be able to sale through this time frame without any ill effects. It isn’t really a “flu” in the traditional sense but the side effects feel very similar to what people describe when they have the flu and hence Keto kind of “borrowed” the term.

What is Keto Flu and How to Avoid It? At its most fundamental the “Keto Flu” is a side effect of what occurs when your body drops the glycogen and associated water weight. When this water weigh is dropped you have a large drop in your electrolytes, primarily sodium level, which are stored within it. If you don’t work to replenish them you will get hit with the Keto Flu.

Now we will discuss ways to mitigate the issues surrounding the keto flu and what you can do before starting your ketogenic journey to be stocked and prepared for this adaptation.

Symptoms Of Ketosis Flu Or Keto Flu

Once you start on a ketogenic diet and are getting ready for its many benefits you start feeling sickly and tired. You may also have multiple issues like a headache, temperament/annoyance issues, or difficulty focusing or concentrating.

Fortunately, it’s transitive and short term, you should soon feel fine again. For most people you will have more energy than before you started the keto diet.

What Causes The Keto Flu?

The transition from a sugar/carbohydrate metabolism to a fat burning metabolism causes a drop in the bodies glycogen storage and excess water related to this.

Once the water and glycogen starts being dumped, typically the fast initial weight loss, you lose vital electrolytes. This is in the form of primarily sodium, which was contained in the same water volume that you just eliminated from your body by starting the Keto diet.

This mass drop in electrolytes causes the body to become “out of whack” as these electrolytes need to be in a very specific ratio to each other to maintain homeostasis of the body systems, without this being correct you can get very ill feeling very fast.

When Does Keto Flu Hit?

This will typically start within 24 to 48 hours as you start to lose the associated water weight. You will want to work on a supplementation plan prior to starting the keto diet and have them on-hand. I would suggest starting supplementing as soon as the first meal.

If you supplement well in advance you will note that you may totally bypass this as that’s what we are working to prepare for you in this article! I hope that you don’t experience this as I never want to myself!

How Do I Beat The Keto Flu?

You need to start increasing your supplementation with at least minimal additions of pink sea salt, I personally use Redmond’s, or you can find something similar, just make sure it isn’t table salt.

The reason I am anti table salt is due to the fact that it is almost nutritionally worth nothing other than the iodine possibly. The investment in your health is worth the cost today, the bag I listed above has now lasted me over a year and may well make it to two years!

The Himalayan and similar sea salts contain far more minerals and helpful electrolytes to keep your body running smooth and level. I would recommend that you learn to add salt liberally to your meals to ensure you are consuming plenty to help yourself through.

What Supplements Can Help With The Symptoms?

Electrolytes are the main supplement you will need to focus on for the first couple of weeks while switching to a Ketogenic lifestyle. If you don’t put some attention to this then you will feel the wrath of the keto flu and understand why you should have spent the time to prepare fully in advance!
