What is keto?

The keto diet is a low-carbohydrate, high-fat diet that’s become increasingly popular in recent years. It’s touted for its weight loss and health benefits, but some people may experience fatigue on the diet.

Your body has two methods of producing energy. It's similar to having two gasoline and one electric engine. Running on glucose is comparable to using a gasoline engine. It's what the majority of people rely on. And, in most cases, it works well enough.

Put simply, ketosis occurs when you body starts running on electricity rather than gasoline. In other words, it's switching from an inefficient gas engine to a much more efficient electric one. However, the transition isn't always easy.

Fatigue is a common symptom of many conditions, including sleep deprivation, anemia, and certain medical conditions. It can also be a side effect of medications or treatments.

On the keto diet, fatigue may be caused by several factors, including:

  • A lack of carbohydrates: Carbohydrates are the body’s primary source of energy, and when you cut them out, you may feel tired.

  • A lack of electrolytes: Electrolytes, such as sodium, potassium, and magnesium, are important for proper hydration and energy levels. When you’re on the keto diet, you may be at risk for electrolyte imbalances.

  • Dehydration: Dehydration can cause fatigue, weakness, and lightheadedness.

  • A lack of vitamins and minerals: Vitamins and minerals are important for overall health, and some people may become deficient on the keto diet.

Why do people try to get into ketosis?

There are many reasons why people might try to get into ketosis. Some people do it for weight loss, others do it for health reasons, and some people just want to see what all the fuss is about.

If you’re thinking about trying the keto diet, it’s important to talk to your doctor first. They can help you determine if it’s the right diet for you and monitor your health while you’re on it.

How do I get into ketosis?

If you want to try the keto diet, there are a few things you can do to increase your chances of getting into ketosis:

Cut carbohydrates

The first and most important step is to cut your carbohydrate intake. This can be done by eating fewer carbs at each meal or by cutting out carbs altogether.

Increase fat Intake

To make up for the lost calories from carbohydrates, you’ll need to increase your fat intake. This can be done by eating more fatty foods or by taking a fat supplement.


Exercise can help you get into ketosis by increasing your body’s need for energy. When you exercise, your body will burn through its glucose stores and start using ketones for energy.

Monitor Your Ketone Levels

If you want to know for sure that you’re in ketosis, you can test your ketone levels with a blood test or urine test.

What are the symptoms of keto fatigue?

The most common symptom of keto fatigue is — surprise! — tiredness. You may also feel weak, have low energy levels, and experience brain fog. Keto fatigue is usually temporary and should resolve itself as your body adjusts to using ketones for energy.

If you’re experiencing fatigue that doesn’t go away or gets worse, it’s important to talk to your doctor. They can help you rule out other causes of fatigue and make sure you’re getting the nutrients you need.

How do I stop keto fatigue?

If you’re experiencing keto fatigue, there are a few things you can do to ease your symptoms:

Get Enough Sleep

Sleep is important for overall health and can help reduce fatigue.

Eat More Calories

If you’re not eating enough calories, you may be tired. Try increasing your calorie intake by adding more fat to your diet or eating more often.

Drink Plenty of Fluids

Dehydration can contribute to fatigue. Make sure you’re drinking enough fluids, especially water, to stay hydrated.

Take a Break from the Keto Diet

If you’re still feeling fatigued after trying these remedies, you may need to take a break from the keto diet. This doesn’t mean you have to stop the diet altogether, but you may need to take a week or two off to let your body adjust.

Keto fatigue is a common side effect of the keto diet, but it’s usually temporary and can be alleviated with rest, increased calorie intake, and increased fluids. If you’re still feeling fatigued after trying these remedies, talk to your doctor. They can help you determine if the keto diet is right for you and monitor your health while you’re on it.

How long does fatigue last in ketosis?

When you don't consume enough carbohydrates, your body enters into a state called ketosis. This can induce nausea, dizziness, irritability, sleeplessness, tiredness, and poor attention in some people. The majority of the time, this lasts for only a few weeks before going away on its own.

Can pre workout help me with keto fatigue?

There is no definitive answer, as each person’s body responds differently to pre workout supplements. Some people find that taking a pre workout supplement helps them with keto fatigue, while others find that it makes no difference. 

Since many pre workout formulas are created with providing the use with more energy in mind, most people have found that pre workout supplements can help with their energy levels and lifting more weight. 

Can I take pre workout while on keto diet? 

As long as the pre workout supplement does not contain any banned ingredients, such as high levels of caffeine, then you should be fine to take it while on the keto diet. However, it’s always best to check with your doctor or a registered dietitian first to be sure.

The fact is, the majority of pre-workout supplements on the market are keto-friendly, with some being more keto-friendly than others. The chemicals in pre-workouts that are supposed to provide energy will not prevent you from entering or maintaining a state of ketosis.

The most important thing to be aware of when trying to maintain a state of ketosis is the carbohydrate count, from dietary supplements and foods. If, for example, your daily goal was to stay below 30 grams of net carbs and a pre-workout supplement had 5 grams of carbohydrates, you could include it into your overall carb budget.
