Keto Fatigue: How Long Does The Exhaustion Last?

The keto diet is a very low-carb food program in which the body gets its energy from fats instead of sugars from carbohydrates. During the beginning phase of a ketogenic diet, there is a period of adaptation that has to take place, where the body transitions from burning glucose as fuel to fatty acids and ketones. This adaptation period will differ on an individual basis, but it can take up to several weeks before energy and other markers are back to—and usually higher than—normal levels. The keto flu starts to take hold after the first few days of the keto diet, and symptoms include fatigue, muscle cramps, and nausea. The symptoms of keto flu last anywhere from one to three weeks.

Keto fatigue is caused by a lack of electrolytes, specifically sodium

Keto fatigue, or the "keto flu", is a common side effect of transitioning to a ketogenic diet. It can cause symptoms such as fatigue, irritability, muscle cramps, headaches, and brain fog. While these symptoms are typically mild and resolve on their own within a week or two, they can last for up to six weeks in some cases.

One of the main causes of keto fatigue is a lack of electrolytes, specifically sodium. Electrolytes are minerals that carry an electric charge and are essential for the proper functioning of the body. When you start a ketogenic diet, your body begins to process electrolytes differently due to the reduced intake of carbohydrates. This can lead to an electrolyte imbalance, particularly a deficiency in sodium, potassium, and magnesium.

Sodium is one of the most important electrolytes in the body and plays a vital role in maintaining blood volume and blood pressure, controlling nerve impulses, and regulating water retention. On a ketogenic diet, you may lose sodium through sweat and urination, as lower insulin levels cause the kidneys to excrete more sodium. This can lead to a range of symptoms, including fatigue, difficulty concentrating, and muscle cramps.

To combat keto fatigue caused by a lack of sodium, it is recommended to increase your sodium intake by salting your food generously or adding a teaspoon of salt to a glass of water. You can also consume bone broth or bouillon, which are high in sodium. Additionally, drinking enough water is crucial, as electrolytes are highly dependent on proper hydration.

Potassium and magnesium are two other key electrolytes that can be affected by a ketogenic diet. Potassium helps maintain blood pressure, control body fluids, and reduce the risk of hypertension. Magnesium plays a role in DNA and RNA synthesis, muscular contraction, and controlling blood pressure. Deficiencies in these electrolytes can also contribute to keto fatigue and its associated symptoms.

In addition to increasing your sodium intake, eating a variety of whole foods that are high in electrolytes can help prevent keto fatigue. These include coconut water, avocados, beef, chicken, eggs, spinach, salmon, and almonds. You can also take keto-friendly electrolyte supplements to ensure adequate intake.

By addressing electrolyte imbalances, particularly a lack of sodium, you can effectively combat keto fatigue and enjoy the benefits of a ketogenic diet without the unwanted side effects.

Keto Fatigue: How Long Does It Last and How to Combat It

Keto fatigue, or the "keto flu," is a common side effect of transitioning from a high- to low-carb diet, and it can make you feel downright awful. The good news is that it's temporary and usually lasts anywhere from a few days to a few weeks. So, how can you combat keto fatigue? Here are some tips to help you get through it:

Increase Your Salt Intake

Increasing your salt intake is an effective way to combat keto fatigue. When you restrict carbohydrates, your body also starts to release an important electrolyte—sodium. This loss of electrolytes can lead to fatigue, muscle cramps, dizziness, and headaches. By adding more salt to your food or drinking bone broth, you can replenish your sodium levels and reduce these symptoms. You can also try adding a teaspoon of salt to your first glass of water in the morning or opt for bouillon cubes or salted bone broth if you don't like the taste of salt water.

Other Tips to Combat Keto Fatigue

While increasing salt intake is a great first step, there are other things you can do to combat keto fatigue:

• Slow Down on Carb Reduction: Instead of drastically cutting carbs, try tapering down your carbohydrate intake over time. This will help reduce the shock to your system and may minimize keto fatigue symptoms.
• Increase Your Fat Intake: When you lower your carb intake, make sure to increase your healthy fat intake. This is crucial because your body needs enough available energy from fat during this transition period.
• Wait to Lower Your Caloric Intake: Don't reduce your calories too quickly. Let your body adjust to the new macronutrient ratios before decreasing your calorie intake further.
• Stay Hydrated: Drink plenty of water, especially during the first week of starting the keto diet. This will help with electrolyte replenishment and reduce fatigue.
• Be Mindful of Electrolytes: In addition to sodium, make sure you're getting adequate potassium and magnesium. You can get these from bone broth or supplements.
• Be Patient: The keto-adaptation period usually lasts between 1 to 3 weeks, so be patient and consistent with your diet during this time.

By following these tips, you can effectively combat keto fatigue and start enjoying the benefits of the keto diet, such as increased energy and focus, without having to suffer through the initial side effects for too long.

The keto diet is a low-carb, high-fat diet

There are several reasons why someone may experience keto fatigue:

• Lack of electrolytes: A ketogenic diet is diuretic, which means that you will urinate more frequently and lose electrolytes such as sodium, magnesium, and potassium. This can lead to an electrolyte imbalance and cause symptoms such as fatigue, muscle cramps, dizziness, and headaches. To combat this, it is recommended to increase your salt intake and consume bone broth or supplements to increase your potassium and magnesium levels.
• Low-calorie intake: The keto diet can often lead to a decrease in calorie intake, as people tend to eat less when switching to a ketogenic diet. This can result in an energy deficit and contribute to feelings of fatigue. It is important to ensure that you are consuming enough calories, especially in the initial stages of the keto diet (1-3 weeks), to prevent fatigue.
• Not fully keto-adapted: It takes time for your body to adjust to using fat as its primary fuel source. During the keto-adaptation period, you may experience fatigue as your body is still transitioning and has not yet become efficient at burning fat for energy. This usually lasts between 1 to 3 weeks but can vary from person to person.
• Carbohydrate withdrawal: When you drastically reduce your carbohydrate intake, your body goes through a withdrawal period. This can result in symptoms such as lethargy, constipation, and diarrhea. These symptoms typically last for a few days to a couple of weeks.

To combat keto fatigue, it is recommended to:

• Increase your sodium intake by salting your food or drinking bone broth.
• Slowly reduce your carbohydrate intake instead of cutting it out all at once.
• Increase your fat intake to ensure your body has enough energy.
• Wait to lower your calorie intake until your body has adjusted to the keto diet.
• Reduce the intensity of your workouts until you are fully keto-adapted.

Additionally, it is important to be mindful of your sleep, stress levels, and other lifestyle factors that can contribute to fatigue. While keto fatigue is common, it is usually short-lived and can be managed by following the tips outlined above.

The keto diet causes an initial reduction in performance

The keto diet is a very low-carb food program, where your body gets its energy from fats instead of sugars from carbohydrates. The body undergoes many biological adaptations, including a reduction in insulin levels and the breakdown of fat. This is a major change for the body, which has likely been burning sugar for energy for decades.

The transition period, or 'keto-adaptation', can take one to three weeks, and sometimes up to six weeks. During this time, the body is transitioning from burning glucose as fuel to fatty acids and ketones. This is a delicate time, and it is important to approach the keto diet in an educated manner. The body is not very efficient at liberating fat from adipose tissue, so consuming enough fat is crucial at this stage.

During the transition, the body is in a state of limbo, waiting for ketosis to kick in and get that constant flow of energy going. This is when the body starts burning fat for energy, and it can take a few days or weeks for this to start working properly. As a result, people often experience tiredness and fatigue during this period.

To reduce fatigue during the transition, you may want to take electrolyte supplements. Electrolytes are often lost because of the rapid reduction in the body's water content. Make sure to include sodium, potassium, and magnesium.

It is also important to increase your sodium intake, as the body loses an important electrolyte, sodium, when it enters ketosis. This can be done by adding a pinch of salt to your drink, or by consuming bone broth.

In addition, it is recommended to slow down on carb reduction. Tapering down your carbohydrate intake over time will help to reduce the shock to the body.

Increasing your fat intake is also important, as the body needs enough available energy.

Finally, it is recommended to wait to lower your caloric intake. Your body goes through a lot of changes when you start a low-carb diet, so it is best to let your body adjust to the new macros before reducing calories.

Keto fatigue can last anywhere from one week to six weeks

When starting a ketogenic diet, it is common to experience keto fatigue, or the keto flu, as your body transitions from burning glucose for energy to burning fat. This fatigue can last anywhere from one week to six weeks, with some people experiencing it for a shorter time, and others for much longer.

During this adaptation period, your body is transitioning from burning glucose as fuel to burning fatty acids and ketones. Your body will also be depleting its glycogen stores, which can lead to a loss of water and electrolytes, causing fatigue. To combat this, it is important to increase your sodium intake and stay hydrated. You may also want to experiment with your sodium intake by adding more salt to your food, as well as ensuring adequate potassium and magnesium intake through bone broth or supplements.

In addition to the loss of water and electrolytes, there are a few other reasons why you might be experiencing keto fatigue. Firstly, your body may not be getting enough fat, which is crucial during this transition period as your body is not yet efficient at liberating fat from adipose tissue. Secondly, you may be eating too few calories, which can happen unintentionally as the keto diet naturally suppresses appetite. Thirdly, your body and brain are going through an adaptation period, which can take one to three weeks for most individuals.

To summarise, keto fatigue can last anywhere from one week to six weeks, and sometimes even longer. To combat this fatigue, it is important to increase your sodium and water intake, ensure you are getting enough fat, be mindful of your calorie intake, and allow your body and brain time to adapt to this new way of eating.
