Why May You Need Potassium On Keto?

If you’re new to keto and want a bit more information, check out our keto beginners guide.

As a quick summary, if you need it, the keto (also known as the ketogenic diet) is a low-carb, high-fat diet (LCHF).

Do I Need Potassium On Keto

The whole concept of the keto diet is that your body transitions from burning glucose, in simple terms, sugars or carbohydrates, to burning fat as its primary fuel source.

For a keto diet, people will restrict their macros to eating;

  • 70% of their calories are from fat
  • 25% from protein
  • 5% from carbohydrates

Sticking to these macros for a period of time will put your body into a state of ketosis. Ketosis is when your body has transitioned from burning carbohydrates as its primary fuel source to burning fat for fuel. It is at this point that you will start to see and feel the benefits of the keto diet.

It is the role of the liver to convert amino acids into small amounts of glucose. This process is called glucogenesis. This is when ketone bodies (ketones) are created.

Eventually, your body will become what is known as ‘fat adapted‘. In simple terms, this means that your body is accustomed to burning fat as its primary fuel source and it will function this way as its default setting.

There are a lot of new terms and abbreviations that you may come across, sometimes it can feel like a new language that you need to learn. In order to help you out and keep you on the right track, we have created a keto terms and keto abbreviations guide, bookmark these to make your keto journey easier.

Some people can be put off the keto diet because of the side effects, however, these are only short-lived and the health benefits of keto far outweigh the side effects.

There is no doubt that the process of getting into ketosis and remaining there is a massive change to the way your body is used to functioning.

Supplements may be able to assist your body with this transition and speed up your journey to your health goals.

What Does Potassium Do For The Body?

Potassium is a mineral that is highly reactive in water. It produces positive charges (electrolytes) when dissolved in the water. But the importance of potassium remains highly underestimated.

Potassium can conduct electricity needed to perform different functions in the body.

They help your body regulate chemical reactions, as well as maintaining the balance between fluids inside and outside your cells, and so much more.

If you regularly consume a potassium-rich diet, it can help maintain blood pressure. It even prevents osteoporosis and offers protection against stroke.

Here’s what more potassium does for the body:

  • It helps regulate fluid balance 
  • It is important for the nervous system
  • It regulates muscles and heart contractions 
  • It can reduce blood pressure
  • Can offer protection against strokes 
  • It can prevent osteoporosis 
  • It can prevent kidney stones 
  • It can reduce water retention

What Will Happen If I Have Too Little Potassium?

When your blood potassium level is below 3.5 mmol per liter, it is classified as potassium deficiency.

In the medical language, it is called hypokalemia. 

Proper potassium levels in the body are responsible for regulating muscle contractions, fluid balance, and healthy nerve function. But many adults do not consume the required amount of potassium.

Hypokalemia can be caused due to shock, fluid loss, malnutrition, medical conditions like kidney failure, and the use of some medications.

Potassium deficiency occurs when the body does not get the required potassium for the proper functioning of the body. 

If you are on a keto diet, you can notice the following symptoms to know whether your body has a proper potassium level or not. 

  • Weakness and fatigue 
  • Muscle weakness and cramps 
  • Digestive problems 
  • Abnormal heartbeat 
  • Breathing difficulty 
  • Tingling and numbness 
  • High blood pressure 

These symptoms are not exclusive to the keto diet, anybody, on any eating plan, could experience these.

Can the Keto Diet Cause Low Potassium?

People who are new to the keto diet world often experience fatigue in the early day, this can be one of the side effects of keto.

While fatigue is one of the major signs that indicate the body is shifting towards ketosis, it is also may be linked to potassium deficiency. 

When an individual eliminates food items like bananas from their diet, potassium deficiency can occur. Eating bananas is not encouraged in the keto diet, as they are high in carbohydrates, even though it is an excellent source of potassium. 

So until somebody new to the diet has worked out how to get all of the nutrients through keto foods, it may be possible that they are deficient.

What Kind of Potassium is Best for the Keto Diet?

Potassium chloride is the highly preferred potassium for ketogenic diets. This form of potassium is also used in the best electrolyte products. 

Potassium Citrate vs. Potassium Chloride on Keto

Potassium citrate is considered a potassium salt of citric acid. But citric acid is known to stop the body from entering the ketosis state.

While many products contain this form of potassium, it is not advised to consume them as they are not ideal for a keto diet.
