How To Tell if You’re in ketosis

how to tell if you're in ketosis

How To Tell if You’re in ketosis : Ketosis is a state in which the body produces ketone bodies on high-fat diets, fasting, or starvation. Also, they can be produced by low carbohydrate diets such as the ketone diet; In addition, it has many health benefits, but it has certain associated side effects that you should know. Therefore, here we will tell you how to know if I am in ketosis.

How are ketone bodies produced?

During an ecogenic diet, a very low level of carbohydrates and a very moderate level of protein are consumed. So, by having this type of diet, it leads to the metabolism of fats in different parts of the body and especially in the liver. Likewise, this fat metabolism produces different ketones that are used by the body as an energy alternative.

Under normal conditions, the body and brain use glucose for energy, although in this case they use ketone bodies. Once the body has relatively normal levels of ketones, fat breakdown begins easily; even those that are in reserve in the body of an individual are metabolized; to be used by the whole body. For this reason, this type of ketone(How To Tell if You’re in ketosis) diet is used to lose weight quickly.

Who can perform the ketogenic diet?

Starting a ketone diet requires a fully functional metabolism with normal values. For this reason, those people who have or suffer from a basic metabolic disease cannot carry out this type of diet. In the same way, those who have some organic insufficiency either in the kidney, pancreas, liver or in the heart. Because these are primordial organs that mobilize large amounts of metabolic processes.

However, performing it can bring consequences and serious metabolic states such as ketoacidosis that could lead to death. Similarly, strict calorie and food control is required; which are often not recommended by specialists during these conditions. So people with basic diseases should refrain from this type of method to lose weight.

How can your body go into ketosis?

To achieve ketosis, carbohydrates need to be restricted to almost the limit of 20 grams or less per day. Similarly, you should consume protein only moderately accompanied by enough fat; to achieve the effect of stomach fullness. However, it is optional to add an intermittent fast which allows to intensify the production of ketone bodies a little more.

Although, the key is to arrive at a practically hypocaloric diet that leads to metabolic and hormonal changes to produce ketosis. On the other hand, entering ketosis takes an adaptation process where ketone levels vary day and day; Also, they generate different effects and changes in the body that may indicate that we are in a degree of mild How To Tell if You’re in ketosis, optimal or out of range.

What are the signs that indicate your body is in ketosis?

During the adaptation process the body generates different changes in metabolic, hormonal and functional levels. Each of these changes are reflected in the body generating different signs; that can be noticed as the adaptation and indicate that your body is producing ketone bodies. In addition, some exacerbation or decrease of these can guide if something is wrong with the diet.

Also, it is important to note that each of these effects and changes are totally temporary during the diet .; that is, they will not be forever nor will they trigger an unfavorable definitive change in your body. That is why, below we will show you what are the signs that indicate that your body is correctly producing ketone bodies:

Weight loss

One of the most noticeable changes in the short term is the progressive weight loss that is associated with caloric deficit. However, it is only a part that consists of the liquids that are lost and make your body progressively slimmer. Although for this it is important to make measurements in specific places of the body such as waist, arms, thighs and buttocks.

Dry mouth and thirst

Consuming plenty of fluids is vital during this diet, since ketone bodies exert diuretic effects on it. So, different hormones that act at the kidney level are inhibited; causing an osmotic diuresis with presence of ketone quotas in urine. This in turn stimulates the thirst reflex to replenish the hydro-electrolyte levels that have been lost during urine output.

Breath and fruity sweat

One of the ketone bodies produced in the diet produces a characteristic smell of decomposed fruit. However, this phenomenon does not occur in all people who carry out this type of diet and is purely temporary; Also, it can be seen when performing exercises with profuse sweating, the sweat may have a slightly stronger smell; although in the same way it is for a certain period of time.

Stomach fullness

Modified diet is a fundamental part of the ketone diet, especially the consumption of fats. Fats proportionally will make your stomach feel full and appetite is avoided. Furthermore, ketone bodies through neurotransmitters and cellular receptors in the stomach walls; They help produce the feeling of satiety and fullness.

Ketosis and ketonuria

The way to know if your body is in ketosis is through a blood test where ketone levels are measured. Likewise, this analysis can be performed through test strips by taking capillary or venous blood. Also, the presence of these in urine give the indication that there are ketone bodies in the body and can be evidenced by test strips

General condition affectation

During the first weeks of adaptation, the body can be generally affected; Because metabolism makes different changes in neurotransmitters, enzymes, hormones, and different organs. Thus, all changes generate a decline in the general state; presenting headache, tiredness and nausea. Additionally, there may be an inability to concentrate and tolerate certain things.

Increased energy

Your body stops having insulin spikes so the typical fatigue that occurs after eating disappears. You will feel much more energy throughout the day after the first few days when we feel dizzy and tired.


Some people may have difficulty going to the bathroom the first few weeks of the diet. This is due to an imbalance in normal sodium and magnesium levels. To eliminate the problem, take a magnesium supplement and incorporate the daily intake of a glass of water with a small tablespoon of salt into your diet.

Are there risks in the keto diet?

Multiple studies have shown that the diet works well for different people. However, it has a relative risk associated with caloric deficit due to poor carbohydrate and protein intake. Also, added to the risk is the loss of fat and lean mass produced by the metabolic effect; even, the security that the acid and base values ​​that people handle during this diet.

Especially, because an imbalance in values or factors that do not depend on the person but on the functioning of her body; likewise, they can create a severe complication such as ketoacidosis(How To Tell if You’re in ketosis). Because ketone bodies are acids that can lower blood pH; causing a series of extremely dangerous signs and symptoms.

Finally, how to know if I am in ketosis is vital when you are on a keto diet. Basically, the diet generates a series of systemic changes that cause the body to undergo producing ketones. Each of these effects are obvious, temporary, and can be quickly quantified. Therefore, it is important to know when they begin to be evident to begin an immediate control.

Potential errors when checking ketone in urine

The level of ketones in urine does not have to be the same as that of ketones in blood. There are several reasons why they may coincide.

The level of hydration in your body can make a big difference in terms of the concentration of ketones in your urine. Dehydration can result in a false positive, which occurs frequently, especially in the morning. Similarly, drinking plenty of fluids (although this is what you should be doing) can result in a false negative from a lower concentration of ketones.

How To Tell if You’re in ketosis : As time goes by, people who follow a ketogenic diet tend to have a lower level of ketones in their urine despite being on a fat-burning basis. At this time a blood test may be necessary to accurately check if the body has entered ketosis, although these are much more expensive and also involves pricking a finger instead of just urinating. If you follow a balanced diet and your body has been in ketosis for the next few weeks, there is no reason to worry.

Ketogenic diets don’t always result in weight loss

Keep in mind that if you maintain a sedentary lifestyle and with little stress you need less carbohydrates. However, it is different if you train regularly or have a demanding job. Carbohydrates help the brain, heart and nervous system to function properly. You don’t need to cut down on carbohydrates to burn fat.


  • Before starting a ketogenic diet, make sure you have informed yourself well. It is not necessary to reduce carbohydrates dramatically to burn fat.
  • Being in ketosis generates a high level of ketones, which can be detected in breath, urine, and blood.
  • Ketone test strips (such as Ketostix) are the fastest and easiest way to check the level of ketones in your urine.
  • Hydration and the time the body is in ketosis can affect the results of Ketostix (urine test strips).
  • Some of the ways to measure ketones include test strips, blood tests, an increase in thirst, or a change in breath odor known as “ketogenic breath.”
