Demystifying the Keto Flu: What it is & How to Conquer it?

So, you’ve just heard about the dreaded Keto Flu?

It’s a common concern among those new to the Keto diet. When you switch to a low-carb diet like Keto, your sodium, magnesium, and potassium levels tend to drop, which might make you feel a bit off.

But fear not! There are ways to make this transition smoother and more comfortable.

First things first, managing your electrolyte levels is essential if you want to get into Ketosis with minimal discomfort. The Keto flu talk can be scary, but it’s just your body reacting to the reduced carb intake.

You may experience some challenges when you drop your carb levels below 20gm, but remember, you’ve got this! Stay strong and determined during this stage.

To tackle the Keto flu, it’s crucial to include foods rich in vitamins and minerals in your daily diet, and consider taking supplements as well. When I started my Keto journey, I noticed a mild headache and a dip in my energy levels by the end of the first day.

It was a bit irritating, I must admit. After doing some research, I learned that I was experiencing the Keto flu, which is totally normal.

You see, when your magnesium and potassium levels are low, your body might not function at its best. Given our fast-paced and stressful lives, it’s essential to ensure a steady supply of minerals and vitamins to cope with the pressure.

The good news is that the Keto flu usually passes within three to five days, but for some individuals, it might take a little longer. Don’t worry, though – it’s just a temporary phase.

I strongly encourage you to stick it out and stay motivated. Remember, you’re on the right track, and this is a sign that your body is adjusting to the new way of eating.

The First Symptoms of Keto Flu:

• Mild to strong headaches
• Feeling of nausea
• Upset stomach
• Low levels of mental clarity / brain fog
• Fatigue
• Lethargy

And as obvious from its name, it is called a flu, because you feel sick. Thankfully, mine lasted only two days and the third day I woke up like a charged person. I was less hungry and ready to take on the world. It’s been exactly six months today, and I don’t regret my decision one bit.

If you are going through the Keto flu and are feeling that you might die, please read on. Deciding to go on Keto, is the best decision that you took for yourself.

What can you ask for more, you get to eat good food, feel great and lose weight too! Trust me, you will be really happy that you took the decision to switch to Keto!

You need to understand that your body has been burning glucose for energy from the day you were born. Now you are forcing it to make a new set of enzymes that will burn fat for fuel. The transition will take a little time.

The first and simplest thing that you can do to help yourself, is to keep yourself well hydrated. If you were already drinking plenty of water before, drink some more and more. Most people will vouch for drinking water mixed with little normal salt, pink salt, and lemon juice.

You will need to go to the bathroom often, as your body will start getting rid of the excess insulin and chemicals and the fluids that have been retained in the body. The good news is that in the first few days itself you will see massive weight loss.

When you lose the retained water, you will also lose sodium, magnesium, and potassium. You actually feel like crap, in the absence of them. If you want to speed up the transition to have fat, eat eggs, bacon, butter, cream. You might think I am crazy, but trust me, it helps. In the first few days, keep the protein in check, as the body might transform it into glucose if you eat excess of it.

What is Lite Salt?

Tata Salt Lite Low Sodium Salt, 1Kg

A lite salt is an alternative to your regular salt. The sodium content in it is lower than your regular salt, and it is enriched with Potassium. Besides Keto, doctors recommend the consumption of this salt to people suffering from kidney diseases, liver failure and a history of steroid use.

If your daily intake of sodium is more than 2400 mg, your blood pressure might rise. We all are aware of the fact that excess sodium also leads to water retention in the body.

So the first thing I did was that I switched to Tata Lite Salt, easily available in all grocery stores in India. I mix about two teaspoons of lite salt, 1 teaspoon of pink salt, the juice of 1 lemon in a litre of plain water. At all times you will find this bottle with me.

Keto flu Warning

If you are presently suffering from any aliment which is preventing your body from eliminating excess potassium from your urine, please consult a doctor before switching to a Lite salt.

Avoid the Lite salt also if you have excessive levels of aldosterone in your blood, a hormonal disorder in which the urinary excretion of potassium is affected.

If you have any more doubts, please consult your doctor right away.

Supplements we essentially need in Keto


Most diets are deficient in potassium, be it Keto or any other low-carb diet. The EDR or the estimated daily requirement of potassium is 2000 mg for a healthy adult. But when you are in Keto you need an additional 1000 mg more.

You can achieve this level of intake by either eating potassium-rich foods or by taking a supplement. But you must be careful about potassium supplements, as excess of potassium can be as dangerous as its deficiency. The AI or adequate intake of potassium is 4700 mg a day.

If you are healthy then you needn’t worry about having excessive potassium, unless, of course, you are taking supplements. Check the label on the food to know their exact potassium content.

The sad part is that most potassium-rich foods are not very Keto friendly. You can include the following foods in order to boost your potassium intake.

Avocados: 1000 mg for an average piece
Nuts: 100 to 300 mg per 30g (depends on the type)
Green Leafy Vegetables: 160 mg per cup for raw, 840 mg for cooked
Coconut Water: 600 mg per cup
Mushrooms: 12% of your daily intake from a cup of sliced mushrooms
White beans, kidney beans, lima beans: they need to be had in moderation. A cup of white beans provides, 1004 mg of potassium.
Yogurt:  again, when had in moderation and within your macros, can offer 255 mg of potassium per 100g.
Salmon and Halibut: are rich sources of potassium, offering 15% of EDR in just 3 ounces (0.11 kg).


At all times, you should be aware of your magnesium intake, in order to avoid getting caught off guard. The RDA or the DV of magnesium for a healthy adult is 400 mg per day. The common signs of magnesium deficiency are dizziness, fatigue, and cramps.

Almonds: 75 mg per 1oz
Cacao powder: 80 mg per 1tbsp
Dark Chocolate: 24% of DV in one small piece
Fish: 75 mg per average piece
Cooked spinach: 75 mg per 1 cup
Avocados: 1 slice offers 15% of the DV
Pumpkin seeds: Just half a cup provides the full daily requirement for the day

Warning: If you are suffering from any kind of kidney disease or are on diuretics, please consult your doctor before taking a magnesium supplement.


Every healthy adult should eat 3000 mg to 5000 mg of sodium. Regulating your sodium intake is very simple. And don’t be afraid to spike it unless you suffer from any medical condition. You can add a few cups of broth or stock to your diet.

On Facebook, there are many groups of like-minded Ketoites. In their conversations, you will see certain terms, which might not make sense to you instantly. Don’t worry, I was equally lost at one time.
