Have you wondered how does potassium help the body to function properly? If yes, then you are reading the right article. In this article, we will share with you the knowledge about electrolytes focusing especially on potassium. Stay hooked to know more.

According to the NCBI (National Centre for Biotechnology Information), it is seen that potassium deficiency happens even when a balanced keto diet is being followed. The high-fat and the low-carb ketogenic diet is obviously helpful for the body. It helps in producing more energy, fall in inflammation, improving liver health, controlling blood sugar, and so on. However, this diet may have many health benefits, but it is not perfect as there are certain important minerals and vitamins that are missing in the diet. These nutrients need to be replenished to keep the body healthy.

Potassium is one such mineral, whose quantity reduces in the body during a keto diet. Therefore, to supply the required amount of the mineral in the body, you must intake good quality potassium supplements during your keto diet. Delve into the article to know more.

What are Electrolytes?

In chemical terms, electrolytes are defined as substances that ionize in solution and gain the capability of conducting electricity. Electrolytes play a very crucial role in controlling the cardiac, kidney, brain, and digestive systems. There are four major electrolytes that our body needs to function properly on a daily basis. The list includes magnesium, calcium, sodium, and potassium.

The foods you eat decide the amount of each electrolyte in your body. These electrolytes dissolve in your body fluid to acquire a negative or positive charge. These charges help them to conduct electrical signals in the body. The electric signals help the body to control many important body functions like creating new cells, tissues, and muscles, and also help in proper brain functioning.

According to Healthline studies, every electrolyte has a task to perform. The function of each major electrolyte is as follows:

  • Magnesium: It initiates the production of DNA and RNA, helps in the muscle and tissue function, helps in keeping the heartbeat on track, regulates blood sugar level, and also boosts your immunity.
  • Calcium: It is the key component of proper bone and teeth formation. Calcium also helps in improving your muscle movement and nerve impulses and blood clotting.
  • Sodium: It is necessary for nerve and muscle function. Also, it helps in controlling the blood pressure and body fluids.
  • Potassium: It helps to regulate heart activities and blood pressure. Also, helps in balancing your body’s electrolyte composition and function, initiates nerve impulses, keeps the bone healthy, and controls muscle contraction.

As you can see, these electrolytes perform very important body functions. Further, in the article, we will discuss the importance, benefits, supplements, and foods of potassium in detail. Keep reading the article to know more.

Symptoms of Potassium Deficiency

There are a lot of symptoms that your body might show to tell you that it is lacking potassium. Some major potassium deficiency symptoms are:

  • Fatigue: If you are feeling fatigued and your energy levels are low most of the time, then one of the reasons for that can be potassium deficiency in your body. But remember, this sluggish feeling can also be due to other reasons like stress, lack of sleep, and improper diet.
  • Muscle Cramps: Muscle cramps and stiffness are the symptoms that your body doesn’t have enough potassium. This disorder is coined as rhabdomyolysis and occurs due to muscle breakdown. Lack of potassium causes this disorder because it is the key mineral of the body that regulates blood flow in the muscle. Decreased blood flow results in less content of oxygen in the muscle, which causes stiffness and cramps.
  • High Blood Pressure: This is a symptom that validates the lack of potassium in your body. Potassium regulates blood pressure by sending electrical signals to the heart. But remember, heart palpitations can also be caused by other serious heart conditions like arrhythmia or uneven heartbeat.
  • Bloating and Constipation: Lack of potassium causes an imbalance in sodium levels in the body, which results in salt-induced bloating. Potassium also helps in the peristalsis of the gastrointestinal tract, which helps to churn the food properly. Therefore, lack of potassium causes problems in the digestive system of your body.

The other symptoms of potassium deficiency are breathing issues, numbness, tingling, and mood swings. These problems occur because of the disturbed signalling owing to the lack of the mineral. Often, the lack of potassium in the body happens due to excessive sweating. If you face any of the symptoms, then we suggest you consult a doctor soon.

Potassium for Ketogenic Dieters

Maintaining a potassium-rich diet on keto may seem difficult, and when you fail to do so, you will face an issue commonly known as a ‘keto flu’. You might experience this while on a keto diet because of the low carbohydrate content supplied to the body. Keto flu can be avoided if you consume proper potassium supplements. And also, there are some keto-approved foods that you can have during keto dieting.

We know that the first food that comes to your mind when speaking of potassium is banana. But we are sorry to say that bananas are not keto-approved. However, there are certainly other great keto foods rich in potassium, which include avocado, mushroom, almonds, beet greens, broccoli, salmon, Brussels sprout, clams, kale, and spinach. Your body requires around 4,700 mg of daily potassium intake.

Always remember, everything must be done within a limit. Do not take in excess potassium through foods or supplements because that too might give rise to a disorder called hyperkalaemia. Hyperkalaemia causes an irregular heartbeat that is, for sure, fatal for your health. Therefore, it is important that you take in a decent amount of potassium and never in excess.
