8 Important Symptoms of Ketosis You Need To Know!

Symptoms of Ketosis: Ketosis is a metabolic state in which your body uses fat for energy instead of glucose. It provides several health benefits, weight loss and reduces inflammation. However, it’s crucial to be aware of the eight symptoms of ketosis.

8 Important Signs of Ketosis

If you never had experience with fastening but want to check if your metabolism has already switched to ketosis? If the following seven eight apply to you, your liver is already producing ketone bodies.

1. Bad Keto Breath

Acetone and related substances are simple ketone bodies that the metabolism usually produces in excess during the switch. The body excretes them in the urine or through the breath – a sure sign of ketosis.

Some people notice this excretion by a taste in the mouth reminiscent of nail polish remover. Others, however, report a licorice-like aroma spreading through the roof of their mouth.

You can combat this bad breath by brushing your teeth frequently. Chewing gum also helps, but be sure to use sugar-free versions – after all, you don’t want to ruin the success of your fast.

2. Dry Mouth

Your metabolism needs water for almost all processes. The change to ketosis lets you initially feel stress, which causes the metabolism to release more of the hormone FGF21. This hormone has increased thirst significantly within two hours in animal studies.

Suppose you seem to be constantly thirsty while fasting—the increased release of FGF21 healthy pieces of evidence the switch to ketosis. However, scientists are still puzzling over the same connections.

Danish researchers’ study published in 2020 showed that increased amounts of FGF21 do not automatically lead to large parts of ketone bodies. Nevertheless, if you consume 3 to 4 liters of fluid a day and still feel thirsty all the time, your body has almost certainly switched to ketosis.

3. Ketone Bodies In Urine

This test can be done easily and quickly at home with test strips. You can get ketosis test strips on the Internet and in any pharmacy. The proportion of ketone bodies is highest early in the morning or the evening.

However, the test strips do not tell you how many ketones are in your urine. In addition, each metabolism works individually. Some people produce fewer ketone bodies, so the urine test does not provide reliable results.

4. Rapid Weight Loss

Has your body lost water, or is it burning fatty acids from excess pounds? It is a cardinal question if you lose weight rapidly while fasting.

Therefore, despite losing weight, a single test such as ketone bodies in the urine is not suitable as the sole proof of conversion to ketosis.

During the first days of fasting, you take in a little salt, which binds water in the body. Therefore, at least part of the initial rapid weight loss during fasting can result in water loss.

Nevertheless, after one week at the latest, the body has usually eliminated most water. If seven days have passed, you can count the numbers on the scale as actual weight loss.


Bone broth is suitable as a drink for any fasting diet, thanks to its low-calorie content. It provides dissolved proteins in an easily digestible form and contains salt.

This way, it counteracts excessive water loss and promotes ketosis switching. If you drink bone broth while fasting, you will lose less water and more weight.

5. Ketone Bodies Breath

A little more expensive than the test strips for urine are the measuring devices for breath. However, they also allow you to accurately monitor whether your body is producing ketone bodies and losing weight.

Some experts consider these measurements unnecessary because you will enter ketosis after a specific time.

However, the meters can be helpful if you find discipline particularly difficult. Not everyone has iron willpower and can control themselves when eating.

After about of sin, the measurements on your breath can tell you if you’re back on track and if you’re losing weight.

6. Keto Flu and Digestive Symptoms

Many people experience flu-like symptoms when their metabolism first shifts to ketosis. The so-called keto flu brings a feeling of listlessness and general listlessness . Some experts recommend Bulletproof coffee to avoid the keto flu, and bone broth can also help.

Some people also react to the change with digestive discomfort. Italian scientists found in a study that epileptic children often respond to ketogenic diets with constipation, vomiting, or heartburn in the first few weeks.

However, the positive effects of ketosis are so convincing that most children stay on the ketogenic diet.


Psyllium Husks have hardly any calories and are an excellent way to combat constipation. To do this, stir one teaspoon of psyllium husks into a glass of water and drink it immediately. Then you drink another two glasses of liquid.

These hulls from the plants “Plantago Indica” or “Plantago Afra” can absorb enormous water. They provide your intestines with fiber, which gently stimulates the muscles. They also have a beneficial effect on intestinal flora.

7. Insomnia and Hardly Hungry

If you fast regularly, it acts like a workout for your metabolism: the chances are good that you won’t experience the keto flu at all during a fast.

Instead, your metabolism shifts into another gear after a few hours, and this not only means that you hardly feel hungry despite fasting.

The restricted food intake also leads to an increase in your mental performance. That’s what scientists in Malaysia found out by following 99 seniors over three years.

The study, published in 2020, proves that interval fasting and switching to ketosis improved cognitive abilities even in the seniors who were already showing slight declines.

8. Ketones In Blood

An increased level of ketones in the blood is another sign of whether you are in ketosis. There are many different meters and variations to measure this, but constantly measuring is a waste of time and money.

Usually, the body does not produce more ketone bodies than it needs after some time.

When this is the case, it starts to access its fat reserves. It supplies the muscles and the brain, reaching the state we want to achieve.

On a keto diet, the body needs energy, and wherehere it gets this from depends on the diet.

  • Usually, the body gets its energy from glucose, into which ingested carbohydrates are converted. The pancreas produces the hormone insulin to transport this glucose into the cells and make it usable.
  • If you no longer supply the body with sufficient carbohydrates through food, insulin production is reduced. The body then no longer needs the hormone because there is hardly any glucose available.
  • The body still needs energy, so the metabolism changes and uses other energy sources.
  • In the process, the liver converts fat reserves into ketone bodies, and your body now gets its energy from these.

You can tell if your metabolism has switched to the change in energy production by various signs.

  • Due to the change and the low blood sugar and insulin levels, you will have a strong feeling of hunger in the first three days after changing your diet to a ketogenic diet.
  • You may also experience severe headaches and fatigue. These signs will disappear after a few days.
  • Once the body has adjusted to the changed metabolism, ketone bodies are also released through breathing. You will notice this by bad breath and smell sweet and sour coming from your mouth.
  • You may also experience a salty or metallic taste in your mouth.

If you experience any of these eight symptoms of ketosis, it’s essential to determine whether you’re actually in ketosis and address any issues that may be causing it.

If you want to be sure, you can do a ketone test and test your blood, urine, or breath for ketone levels. As long as you feel good and lose weight, there is generally no need to do this.
