What Causes Keto Flu?

Low-carb dieters have a peculiar combination of symptoms. The keto flu is a collection of symptoms that include headaches, lethargy, weakness, irritability, muscular cramps, and sleeplessness. While they are most noticeable in the early stages of a ketogenic diet, their imprints can last a long time if the underlying reasons are not addressed.

The keto flu is strange in that it isn't mentioned in most medical papers. Even the keto community is divided on the cause. Dehydration is blamed in one piece, carb withdrawal in another, and fiber deficiency in still another. The standard recommendation is to give it time.

It's likely that as time passes, your symptoms will improve. Waiting will only make matters worse if your keto flu is caused by a lack of salt. Sodium levels will continue to fall, and your body will respond by reducing blood volume and causing dehydration, despite your efforts to stay hydrated. When this happens for an extended period of time, your body will rob your bones to make up the difference.

There isn't just one reason for the cause of keto flu. Dehydration and low salt levels, for example (both frequent on low-carb diets), generate symptoms that are almost similar.

To get rid of the keto flu, you'll have to conduct some detective work. This essay was written to serve as a guide for you. Here, you'll discover the most common causes of keto flu, as well as how to treat them.


What Is Keto Flu?

The keto flu isn't a tropical disease; rather, it's a trendy name for a group of symptoms associated with going keto. Symptoms of the keto flu include constipation, headache, muscle cramps, weakness, fatigue, irritability, brain fog, diarrhea and weakness.

With this list of symptoms, it's easy to see why “flu” was chosen as the term for this sickness. These symptoms usually appear within a few days of starting the keto diet, however this isn't always the case. Some people are dissatisfied with the program after a few months.

What Causes Keto Flu?

The keto flu is the result of a shift in lifestyle. When you initially “go keto,” you cut out the majority of carbohydrates, which lowers blood sugar and insulin levels. Low insulin triggers the ketosis bat signal, and the body switches to a fat-based metabolism – whether from your plate or your body – as the predominant source of energy at rest.

The human body, on the other hand, is a complicated and delicate machine. Cutting carbs changes a number of knobs, not just the fat-burning one.

In general, cutting carbohydrates induces keto flu, but there's a lot more to say about it. Let's start with particular reasons and then move on to solutions.


X Causes Of Keto Flu

Low Sodium

Nerve impulses, fluid balance, and a number of hormones are all regulated by sodium. You won't feel, perform, or sleep well if you don't get enough salt.

Low salt, for example, raises norepinephrine, a stimulating hormone that isn't good for sleeping. Low sodium levels are also a problem for competitive athletes. They cramp up, lose cognitive function, and occasionally suffer from brain damage.

Low-carb dieters are also at danger of sodium shortage. When you eat a low-carb diet, your pancreas produces less insulin. Reduced carbohydrate intake leads to lower insulin levels, which allows your body to more easily access stored body fat. But there's a catch: it also reduces salt retention.

Insulin pushes its nose everywhere while it's circulating, including into your kidneys. Insulin specifically instructs your kidneys to store salt.



Dehydration manifests itself in the same way as low sodium does. Headaches, cramps, exhaustion, and other symptoms are common.

The sodium range in the blood that is necessary for survival is quite narrow. If the body is losing water, it must also be shedding sodium, and if the body is shedding sodium, it must be shedding water. On keto, you excrete not just more salt, but also more water. The essential premise is the same.

This does not imply you should begin hydrating excessively, since this will dilute blood sodium levels and aggravate low sodium symptoms.


Carb Withdrawal

Getting sugar-free is analogous to going off a drug, and I don't mean that metaphorically. When it comes to those who have a history of binge eating or even just having difficulties with portion control, there is some evidence that their brains process foods high in refined carbs differently than others who don't.

In any case, “sugar addicts” not only behave like drug abusers, but their brains also have neurochemical commonalities.

You can't have dopamine-driven positive sensations if you don't eat carbohydrates (which your digestive system converts down into sugar). There's a reason why so many comfort meals contain both carbs and fat.

If you were on a high-carb diet before starting keto, you may suffer keto flu symptoms as a result of sugar withdrawal. Fortunately, this is the most likely transitory reason.


Less Glucose Goes To The Brain

When you consume carbohydrates, your brain is largely powered by glucose. When you reach a ketogenic state, however, you reduce your glucose consumption. As a result, there's a chance that the brain will have less glucose accessible.

This is where ketones, your brain's backup fuel, come in. Ketones provide clean, efficient energy to the brain.

Even yet, the switch from glucose to ketones isn't always seamless. Researchers believe that this shift may induce symptoms during the first few days of keto diets.
