In this post, you will find out everything you need to know about the signs and symptoms of ketosis and how do you know when your body is in ketosis?

When you are trying to lose weight, one of the most important things you can do is enter into ketosis.

Ketosis is a metabolic state where your body is burning stored fat for energy instead of carbs. This usually happens when you restrict carbohydrate intake and increase your fat intake, thus providing your body with an alternate source of fuel.

But how do you tell if you’re in ketosis or not? It’s a common question many people have.

In this post, I will discuss the signs and symptoms of ketosis so that you can determine whether or not you’re in this fat-burning state.

Knowing these signs will help keep you motivated and on track with your diet!

Is it good for your body to be in ketosis?

Yes! When you are in ketosis, your body is burning stored fat for energy. This is a good thing because it means that you are losing weight. However, some people may experience some side effects such as headaches, fatigue, and irritability. These side effects are usually temporary and will go away once your body gets used to being in ketosis.

What are the first signs of ketosis?

The first signs of ketosis are usually fatigue and irritability. This is because your body is not used to burning fat for energy yet. As your body adjusts to this new way of fuel, these side effects will go away. Other early signs of ketosis include increased urination, decreased appetite, and dry mouth.

How long does it take for your body to go into ketosis?

Usually, it takes around 2-4 days for your body to enter into ketosis, as long as you’re eating under 50gms of carbs per day. However, this can vary from person to person. Some people may enter into ketosis faster, while others may take longer. It also depends on factors such as age, metabolism, and physical activity.

10 Common Signs And Symptoms Of Ketosis:

1. Temporary Fatigue

Fatigue is one of the most common side effects when your body first enters ketosis. This is because your body is not used to burning fat for energy yet and is still adjusting.

Dehydration can also bring about fatigue since your body tends to release more water when it’s using up all its glycogen (glucose) stores. Drink plenty of water and get rest when you’re feeling fatigued.

You may also want to try an easy homemade keto electrolytes drink to relieve some of the symptoms of ketosis temporary fatigue.

Luckily, the fatigue and low energy will go away on it’s own after your body becomes used to using fat for energy and running on ketones.

2. Headache

Headache is another common ketosis side effect. When you enter ketosis, your brain starts using molecules called ketones for energy, replacing carbohydrates.

This can lead to a drop in sugar levels and electrolyte imbalance, thus leading to headaches.

But don’t worry, these headaches will only last a couple of days.

Make sure you’re getting enough electrolytes into your system and you should be feeling better in no time!

If the headache doesn’t subside in a few days you should be seeking help for your doctor as there may be other causes.

3. Digestive Issues (Constipation, Bloating or Diarrhea)

Our bodies are a marvel of biological engineering. The way we digest and process carbohydrates have a completely different mechanism from how we digest and process fats.

When you first start a high-fat, low-carbohydrate diet, your digestive system will go through some changes as it adapts to this new way of eating.

You may experience constipation, bloating or diarrhea as your body gets used to breaking down and digesting more fat.

This is normal and usually goes away after a week or two. Don’t forget to get enough fiber into your diet during this time!

4. Bad breath

This is quite an interesting symptom that’s often seen when starting on keto. You’ll notice that in the first couple of days, your breath will have a fruity, metallic smell similar to that of nail polish remover.

This is because when fat is broken down into ketones, one of the ketones is acetone, which is exhaled through your breath, causing the bad breath. source

Once your body gets more efficient in using ketones, your breath will go back to normal. In the meantime, you can try using sugar-free keto gum or mints to help with bad breath.

5. Insomnia

Many people find that they have trouble sleeping when they first start a ketogenic diet.

Combined with the stress of sudden metabolic changes, fatigue, and low blood sugar levels, your body goes through shorter REM (dream) sleep cycles.

But once your body gets used to keto, you will enjoy deep, restful sleep in the long run.

A study also found that keto diet increases the production of adenosine which has been linked to increased slow wave sleep patterns at night therefore leading to a better sleep.

6. Appetite Suppression

One of the great things about keto is that you tend to feel less hungry in general. No more midnight cravings or snacking throughout the day!

This is because ketones help to regulate appetite by reducing the production of ghrelin (an appetite hormone), thus telling the body that it’s well-nourished. source

Keto dieters often find that they can go for longer periods without feeling the need to eat. This can be great for weight loss or simply for those who don’t enjoy feeling hungry all the time.

So, if you’re finding yourself not feeling as famished as usual, it’s a good sign that your body is in ketosis!

7. Muscle Cramps

This is another common side effect, especially in the beginning stages of keto. When your body breaks down glycogen stores for energy, it also flushes out water and electrolytes along with it. source

This can lead to muscle cramps.

To combat this, make sure you’re getting enough electrolytes into your system. This includes salt, potassium, and magnesium.

You can get these from foods like leafy greens, avocados, nuts, seeds, and coconut water. You can also supplement with electrolyte powders or drinks if needed.

8. Increased Cognitive Performance

This is possibly the best indication of ketosis as you’ll notice a considerable improvement in cognitive performance.

This is because when your body is in ketosis, it’s using ketones for energy instead of glucose.

Ketones have been shown to provide a more stable source of energy for the brain, which can lead to improved focus and concentration. source

9. Increased Ketones in Your Blood

Ketosis produces ketones, which are water-soluble molecules that can be used as an energy source in your cells. When you’re in ketosis, there will be an increase of ketones in your blood within the range of 0.5 – 3 mmol/L.

You can test this via a ketone blood test using a keto blood meter kit, and it’s the easiest way to know whether you’re in keto.

Once your body starts using ketones for energy, you’ll notice a slight drop in the level of ketones in your blood. But as long as it’s above 0.5 mmol/L, you can be sure that your body is still in ketosis.

10. Weight Loss

Last but not least, one of the main reasons people go on a ketogenic diet is for weight loss. And as you start to burn more fat for energy, you will notice that the scale starts to move in the right direction!

You can expect to lose around 0.5-1 kilograms per week after the first few weeks of starting keto.

But keep in mind that during the first few days, the loss in weight is actually water loss. source

It is only with consistent ketosis over time that you will start to burn fat and lose unwanted weight.

Summary

As you can see, there are a couple of side effects you might experience during your first few days on keto.

Some of them are pleasant and some are not so pleasant.

But don’t worry, they will all go away eventually! And once they do, you’ll be reaping all the benefits that come with being in ketosis.

So hang in there and enjoy the ride!
