Are you fasting, but feeling drained and lethargic? That’s because when you fast, your body eliminates electrolytes through urine and sweat. If you don’t replace them, you may become dehydrated and experience symptoms like headaches, fatigue, and dizziness.

But how do you get electrolytes while fasting? We’ll cover the basics of electrolytes, how to get electrolytes while fasting, and how to make homemade electrolytes while fasting. By the end of this post, you’ll have a better understanding of electrolytes and how to get them while fasting, and how to manage Keto flu symptoms on intermittent fasting.

What Are Electrolytes?

Electrolytes are essential minerals in your blood, urine and other body fluids that carry an electric charge. They are important because they help regulate the amount of water in your body, the acidity of your blood (pH), your muscle function, and other important processes.

Common electrolytes include sodium, potassium, and calcium.


salt, cooking salt, rock salt

This mineral is essential to maintaining equilibrium within and outside cells and is necessary for proper nerve and muscle activity and blood pressure. If you’re deficient, you can expect headaches and spasms.

The Daily Value of sodium is between 1500-2300 mg according to FDA.


Potassium is often considered as the most important electrolyte. It’s a vital electrolyte that assists with regulation of fluid balance and nerve and muscle function.

Adequate potassium intake may also help prevent kidney stones, reduces your risk of high blood pressure and maintain bone health.

The FDA updated the Daily Value of Potassium to 4700 mg.


Everyone knows calcium makes your bones strong but did you know it also keeps your heartbeat steady and facilitates muscle contraction and blood clotting?

The updated Daily Value of calcium according to FDA is 1300 mg.

Why Do You Need Electrolytes When Fasting?

Intermittent fasting has become a trend lately with people all over giving it a go.

It’s a pattern of alternating between consuming meals and fasting – usually, this means having a set window of time where you can eat, such as 8 hours, and then not eating at all for the other 16 hours.

How to get electrolytes while fasting

Electrolytes are essential for maintaining optimal health. They’re responsible for helping to maintain fluid balance and blood sugar levels, as well as energizing the body.

When fasting, it’s important to ensure you’re taking in enough electrolytes to avoid any health risks. Below, we’ll outline the best sources of electrolytes for increasing energy and preventing health risks during fasting.

If you’re wondering how to get electrolytes while fasting, water is the top choice. You can give it a salty kick with a pinch of Himalayan pink salt, and even a few drops of lemon.


 Broths are also teeming with minerals that help keep you hydrated; veggie and bone broths are great options for increasing electrolyte intake.


avocado, food, fruit

Don’t forget about avocados for a potassium and magnesium boost – have them as a snack or add them to salads or smoothies.

Nuts and Seeds

 Nuts and seeds like almonds, cashews, and pumpkin seeds are also full of magnesium and minerals and can be eaten as a snack or added to meals.

Homemade Electrolytes For Fasting

Making electrolyte drinks at home is simple, and only requires a glass or water bottle, a teaspoon, and a source of electrolytes (salt, potassium, magnesium).

To make the drink, simply add the desired amount of electrolytes to the glass or water bottle, and then add water until it reaches the top of the container. Swirl or stir the mixture until the electrolytes are fully dissolved, and then drink as needed.

Another homemade electrolyte drink can be created with avocados.

Cut one avocado in half, and spoon the flesh into a blender. Along with the avocado, add two glasses of water, one tablespoon of lemon juice, and a quarter teaspoon of Himalayan salt to the blender.

Mixture should be smooth and creamy after blending.

Keto Flu symptoms during intermittent fasting

Keto Flu is a term that’s used to refer to a set of symptoms that some folks encounter when they jump on the low-carb, high-fat diet bandwagon or start intermittent fasting.

These side effects are much like the flu and can include headaches, queasiness, wooziness, exhaustion, irritability, difficulty sleeping, constipation, and diarrhea.

Apparently, it’s all due to a temporary imbalance of electrolytes like sodium, potassium, and magnesium in the body.

When you follow a low-carb, high-fat diet or fast for long periods of time, your body starts to produce ketones and that’s what your body uses for energy instead of glucose.

 This process can cause the body to excrete more electrolytes, leading to an electrolyte imbalance, thus resulting in the Keto flu.

Preventing Keto Flu during fasting

If you want to reduce Keto flu symptoms while fasting, here are some tips you can follow:

1. Take it easy

Don’t jump right into a Keto state – ease into it gradually over a few days or weeks. This will help your body adjust to the changes without discomfort.

2. Stay hydrated

water, drink, body

Make sure to drink plenty of fluids and electrolytes like bone broth or sports drinks to make sure you’re not dehydrated.

3. Shake it up

salt, sea salt, spoon

Make sure to add a pinch of salt to your meals or salt water to keep your sodium levels in check.

4. Potassium and magnesium

Don’t forget about these important minerals for electrolyte balance – eating avocados and spinach will help!

Do you need Electrolyte Supplements?

What you need in terms of electrolyte supplementation really depends on a lot of factors. Let’s break it down:

What do you eat? If you’re eating a good variety of food, like fruits, veg, nuts, and seeds, you probably won’t need any extra electrolytes. But if you’re vegetarian or vegan, you might have to pay more attention to what you’re getting.

What kind of exercise do you do? High-intensity exercise can cause you to sweat out electrolytes, so if you’re doing a lot of that, you might need some extra supplementation to keep that balance right.

 And finally, any health conditions you have to consider? If you have something like kidney disease, you may need to take medications or supplements

Electrolyte supplements to consider

There are many electrolyte supplements available on the market, and it can be difficult to know which one to choose.

Here are three electrolyte supplements that may help you replenish electrolytes lost during fasting:

Potassium citrate is a type of salt that is often used to replenish electrolytes. It is helpful in preventing kidney stones by reducing calcium levels in the urine. It also has an alkalizing effect and helps in regulating blood pressure.

Sodium chloride is another type of salt that can be used to replenish electrolytes. Remember to choose Himalayan salt instead of sea salt as they contain microplastics caused human pollution.

Magnesium glycinate is a mineral that is high absorbable by the body. It also has minimal digestive side effects and it’s good for maintaining healthy electrolyte levels.
