The “keto flu” is a name given to a set of carbohydrate withdrawal symptoms that may occur in people who start a low carb diet that results from altered hormonal states and the electrolyte imbalances that may occur with it. In other words, it describes a cycle in the body adapting to a newly started low carb diet.
Keto stands for ketogenic which as you may know is a very strict low carb eating plan. In reality a better name would be “low carb flu” since the ketogenic diet is not the only low carb plan and you can get similar symptoms on other low carb diets.
Keto Flu Symptoms
First of all you should realise that no two people are alike, so some people may be lucky enough to have no symptoms at all whereas other people may be unlucky enough to encounter full-blown flu-like condition. Lets look at some of these symptoms
• Mental fog
• In some extreme cases, high blood pressure and arrhythmia (Heart rhythm problems)
How Long Does Keto Flu Last?
Once again the duration for keto flu varies from person to person. While some may have slight and even unnoticeable symptoms for a day or two, others might have an over the top symptom for a week or more, it really depends on how quickly your body adapts to a reduction in carbs.
Once the keto flu is over you can expect a huge surge in energy levels, and once that sugar habit is fully kicked, often people feel better than ever.
The key here is that you need to be patient as your body takes time to adapt, and know that it will pass, and if it does not you should seek the attention of a qualified medical professional. For most people any symptoms that occur end within two weeks’ time.
Keto Flu is A Misunderstood Condition
People who experience keto flu after going on a low carb diet are sometimes forced to believe that they are suffering due to the diet they are on and carbs are good for the health after all.
However, in reality what this is showing is how dependent they have been on carbs, as their body is trying to survive without carbs and sugary substances. In truth, carb intake, and especially refined carbs that come from processed food, sugar, sugary foods and drinks is at epidemic levels, and carb addiction is rampant in the United States and other parts of the world.
It’s not your fault, those carbs are everywhere, congratulate yourself on making changes for the better with a low carb diet!
How To Reduce Keto Flu Effects
There is no doubt that that the Keto flu can be nervewracking but sadly it is sometimes a necessary evil but teh good news is that there are some things that can be done to reduce the symptoms if they appear.
Replenish your electrolytes: Lack of electrolytes in the body is one of the major causes of keto flu. Electrolytes are the minerals found in the body and they affect its water content, acidity of the blood and functionality of the muscles.
Additionally, low carb diets feature lower insulin levels that can send a signal to the kidneys to discard excess water, this in turn leads you to drink more and this results in flushing out even more electrolytes, where sodium, potassium and magnesium deficiencies can occur. You will have to replenish them by using supplements and with food.
• Add in some salt: Normally, the average diet is overloaded with salt, but a ketogenic diet eliminates refined and processed food and focuses on eating whole real food so when you start keto you will naturally reduce salt intake, which reduces water retention. Since a low carb diet is naturally diuretic, there is no need to worry about water retention.
Generally, 5 grams of salt daily is ideal for keto flu and to replenish electrolytes, you can also get it from drinking 2 cups of broth or adding soy sauce and other sauces that have potassium to your meals.
Bone broth is your friend on the keto diet, and only requires the simmering of chicken, beef, lamb or any meat bones in water for about a day, if you do not want to make your own broth tehn you can purchase canned broth or stocks from stores that work well too, just make sure to read the labels for added ingredients or preservatives that you do not need.
These ready made bone broths can be expensive though but a worthwhile investment – in fact I would stock up on these if you are reading this and have not decided to go on a keto diet yet.
Drippings from cooked meat have a high concentration of potassium, so use them to make sauces.
• 300 mg of magnesium can be taken in supplement form.
Keto flu is a process that most dieters undergo while starting their weight loss or weight gain journey. While it cannot be avoided for some, you can reduce symptoms while your body adapts.
As always you should consult a doctor if the symptoms become too severe to handle alone.
