Keto Headache Symptoms And Treatments

Despair, Alone, To Be Alone, Archetype

Those who have attempted the ketogenic diet will likely grimace when the topic of “keto headaches” is brought up. They will then share the most unpleasant experience they have had. Many individuals who follow the keto diet have their own personal negative experience with the related headaches. They are a relatively common side effect of the diet.

If you are unfamiliar with the keto diet, the information in the following passage may not be entirely understandable. The basic understanding of a keto diet is that it involves substituting carbohydrates with beneficial fats. This changes how your bod uses energy.

Low Carb Diets Give you Headaches

A ketogenic diet causes your body to enter a state of ketosis, which is why it is called the Keto diet.

Entering ketosis is comparable to going to the state of Florida – and caution should always be taken with both. When the levels of carbohydrates in the bloodstream are too low to generate energy, the body begins to use stored fat as an energy source.

The keto diet has a lot of possible advantages, but also possesses a few dangers. Keto headaches are a side effect of ketosis. Many parts of the body have difficulty adapting to a ketogenic diet due to their preference for carbohydrates.

Switching from utilizing glucose for energy to relying on fat as a fuel source is similar to trying to use diesel in a gasoline engine. Instead of your car having mechanical issues on the highway, you get a debilitating headache that can stick around for over a week.

Mental Fog Is Normal at the Start of Keto

During the induction phase, a noticeable warning sign is the brain’s lack of its usual fuel supply – glucose. If you’ve never consumed a diet that is low in carbohydrates and high in fat, your brain has been obtaining its energy primarily from carbs.

When you raise the amount of fat you are consuming and lower your intake of carbohydrates, your body starts to consume the last of its stored glycogen. Initially, the brain will be unsure of how to source the energy it requires due to the absence of carbohydrates.

It is common to zone out, suffer from headaches, and become easily irritated.

A useful strategy to battle these signs is to stick to a low-carb diet when you first begin. Your body is made to exhaust its glycogen reserves quickly in this way.

Lots of folks attempt to reduce their consumption of carbohydrates over time, but it will only make their difficulty concentrating persist for a longer period.

When you enter into ketosis, the vast majority of the brain switches to ketones as the primary source of fuel instead of glucose. The transition may occur over a period of a few days to as long as two weeks.

Fortunately, ketones act as an effective energy source for the brain. Once your brain has become accustomed to burning fats as an energy source, optimal cognitive functioning is achieved.

Research has demonstrated that those who have been on a ketogenic diet for a extended period of time tend to have better brain functioning. The keto diet has even been explored as a potential solution for memory loss and various other brain conditions.

The Keto Induction Phase Is Stressful on Your Body

Without the high amount of sugar typically sourced from carbohydrates, your blood sugar will begin to decline and cortisol, the stress hormone, hikes up in production.

The adrenals produce a glucocorticoid called cortisol which helps keep your energy level high enough for survival. When your blood sugar dips, your brain signals your adrenal glands to generate cortisol. Your body will begin to make use of glycogen (stored glucose) as an energy source.

The keto diet can seem daunting because it involves minimizing your intake of carbohydrates, which may cause your body to produce higher levels of cortisol due to the additional stress it may bring on. But this isn’t the case. Gradually, your body will adjust and become inclined to burn fat as energy through the state of ketosis.

Researchers examined the effects of three different dietary regimens: a low-carbohydrate approach, a low-fat method, and a low glycemic index method. The research indicated that the varying diets provoked varying metabolic reactions, with the low-carbohydrate diet having the most substantial influence.

Keto flu is an odd one. There is no sound, scientific evidence for it but (as those who have encountered it know) it is incredibly authentic and unpleasant.

Keto flu is aptly named, consisting of a variety of unpleasant flu-like symptoms that can occur after significantly reducing one’s carbohydrate consumption.

Keto headaches are common symptoms of keto flu.

How Long Does the Keto Headache Last

For instance, if you have been consuming little carbohydrates prior to initiating the keto diet, and have been eating plenty of greens (or taking a top-notch greens health supplement), chances are that you won’t feel any discomforts or that they will be of limited duration.

Normally, the keto headache can linger for 24 hours to seven days. In uncommon instances, it can take up to two weeks for the effects to lessen.

Some folks opt to start the keto diet on a weekend so the disruptions to their daily routine will be kept to a minimum while the less pleasant effects are more bearable.

Dehydration Is Common During the Keto Induction Phase

When you start following a diet that is low in carbohydrates and high in fat (ketogenic lifestyle), your body will start to eliminate surplus water and fluids.

Try not to become too thrilled when you observe a major decrease in weight during the early stages of the keto diet. The amount of weight lost does not only come from the burning of fat; it is also due to the removal of water from the body.

Ketosis is known for its strong diuretic effect. This implies that your body is releasing both water and electrolytes, causing a decrease in the amount of water that your body is retaining.

Water is stored in your body from carbohydrates. When you reduce the amount of carbohydrates you consume, your body quickly eliminates water. For every gram of glycogen (from carbohydrates) consumed as an energy source, two times the amount of water is discharged.

Once your body begins to use ketones for energy, it stops using glucose as an energy source, but you will still experience water loss. Having ketones in your system will result in increased urination.

It’s important to drink lots of water when cutting down on carbs to keep dehydration at bay and maintain good health and wellness.
