What is Keto Flu and How to Get Rid of It

Keto Flu

Of all the diet plans that people looking to lose a little weight follow today, popular is the keto diet plan, and not without reason.

This has, over the past couple of years, proven to be one the most effective, giving the world more slimmer, healthier people, of which the next is going to be you.

But now that you are here, we are concerned about you, for chances are you have been affected by the so-called keto flu.

In that case, don’t worry, we are here to help you. Read on as we tell you all that you need to know about the notorious keto flu.

How Keto Works

This is a diet plan that’s low in carbs and high in fat, and yes, despite the doubts, it is considered healthy and safe. So, don’t worry, the fat won’t lead you to put on weight.

This is because now that you are on a ketogenic diet, the fat in your body is no longer the secondary but a primary source of fuel in it.

This is mainly because you no longer have glucose acting as the main source of energy in your body.

What happens in the process is the reduced carbs in your body soon start to burn ketones, which are the byproducts of fat breakdown and hence much needed when you are on the keto diet.

No Carbs. Only Fat

In other words, fat is now being burnt for energy and this is what ketosis is all about, just like it is when you are on a period of starvation and fasting.

However, remember that all this is true only when you are on a low-carb diet, so no cheating or you are going to be seeing adverse effects instead.

Remember that you can take a maximum of 50 grams of carbs a day, and anything more than that is considered a crime when you are on a keto diet.

What Is the Keto Flu?

This is nothing but a set of symptoms that some individuals on a keto diet may get to experience. Also known as the carb flu, the disease is marked by the same symptoms that one gets to experience during the ordinary flu.

This often happens at the time when a person begins his keto diet, somewhere in the first few days with the symptoms more severe for some.

The reason for this is that your body is trying to adapt itself to this low-carb diet.

So, the above could be true for you if you are someone who has, till now, been used to a high-carb diet.

This is more of a shock to your body which is otherwise used to a high-carb diet. Now that you are not going to be eating a lot of rice and will be taking absolutely no sugar (not even in your coffee) your body has much to deal with.

Symptoms Of the Keto Flu

Symptoms can include nausea, diarrhea, headaches, soreness in the muscles, and a general feeling of irritability. In addition to that, an individual may also experience brain fog, have some trouble sleeping, and even experience some food cravings, which can be accompanied by the stomach and intestinal pains.

And this is quite expected, isn’t it? But don’t worry. Just make sure that you get lots of rest, just like you would with any flu.

It’s only going to be a matter of time before your body is going to get used to the change and you will be back in full swing, even on your keto diet.

What’s more, you are even going to see the results when you stand before the mirror which is going to be all the more reason to enjoy your keto diet.


1. How long does ketosis flu last?

The keto flu can last for a week and in some cases, even less. The maximum time that you would probably take to recover completely is two weeks, which again is rare.

There are still extreme cases when it can go up to a month, and in such a case, it would be a good option to get word from your doctor as to whether or not you can continue with your keto diet.

2. What does keto flu feel like?

The keto feels like just another flu with the same symptoms that show when you are otherwise hit by a flu. However, the severity of the symptoms can vary from person to person just as it is in the case of the duration of the flu

3. Does Keto Flu mean it’s working?

Sadly no, getting the flu may not always mean you are on effective ketosis. Remember the flu is just a way for your body to react to the carbs that you are losing.

4. How do you fight keto Flu?

Water, rest, and a proper keto diet are some of the most important things that you are not allowed to miss out on if you want to stay away from the flu.

Avoid any kind of strenuous activity at all costs. Stay in bed if you have to. The more you rest, the faster you will recover from the keto flu.

5. What is the Fastest way to cure the keto flu?

Stay hydrated. This is the number one rule for someone trying to recover from the keto flu. And then, make sure that you are getting plenty of rest. Grab a couple of leaves if you have to and do not pull stunts with your health when on the keto diet.

Cut down on the fat slowly and not all at once. You don’t have to jump into your keto diet.

Make sure that you are getting enough fat now that your body is not going to be taking in any carbohydrates.

6. Should I eat carbs with keto Flu?

The idea is to slowly cut down on the carbs, and then chances are you won’t get the flu when on a keto diet. But now that you have already begun your diet, we suggest you do not mess it up but take some rest till you recover from the flu that has come as a result of your keto diet.

7. Does Saltwater help with Keto Flu?

Saltwater can at times help alleviate the symptoms of your flu. This can at times happen within a period of 15 to 30 minutes.

You can do this by adding some salt to the water you drink when you are having the flu. However, for the best results, make sure that the salt you use is unrefined.

8. How to Prevent Keto Flu?

No one wants to be down with the keto flu and neither do you. So, if you are worried, here is a way to stay away from the flu.

Drink a lot of water, get a lot of sleep, add a good amount of salt to your food, and most importantly, make sure that you are consuming the right amount of fat, for when you are on a keto diet, this becomes your only source of fuel.
