Ketosis can occur naturally within the body, for metabolic reasons, or it will probably be induced through a certain variety of weight-reduction plan. On this process, the body uses its own fat or fat from food to supply energy.
This is alleged to bring some advantages – for instance, on the subject of weight reduction or controlling one’s weight. Nevertheless, there are also some undesired consequences related to gastrointestinal, metabolic, and bone alterations.
In this text, we’ll take a better have a look at what ketosis is, the way it takes place, and inform you about its symptoms.
What does “ketosis” mean?
In line with its etymology, this term comes from keto or keto (in Latin), which has to do with ketones. Along with the suffix -osiswhich is a frequent formant in disease names, it denotes an abnormal condition, degeneration, wasting, or disorder.
In summary, the meaning of the word ketosis in the present medical field refers to a condition wherein there’s an abnormally high level of ketones within the body. Ketones are organic compounds which have a carbonyl group attached to carbon atoms.
In line with researchwithin the absence of carbohydrates, fats are degraded for energy, producing ketone bodies within the liver. One of the best-known are 3-hydroxybutyrate (3HB) and acetoacetate (AcAc). These are transported to the tissues to enable the body to operate properly.
The possible causes of ketosis
Ketosis occurs when the body begins to make use of fats because the most important source of energy as a substitute of carbohydrates. Especially when these will not be available in sufficient quantity.
There are several possible explanations or causes, that are as follows:
- Activated lipid energy metabolism while pregnant and likewise in childhood
- Diets wherein there may be a low carbohydrate intake
- Exercise or intense physical activity
- An absence of growth hormones
- Prolonged periods of fasting
- A weight-reduction plan that’s very wealthy in fats
- Metabolic disorders
- Diabetes and hypoglycemia
- Alcohol intoxication

The ketogenic weight-reduction plan
The so-called ketogenic weight-reduction plan or keto weight-reduction planis precisely made with a purpose to burn fat by decreasing the consumption of carbohydrates. This refers to sugars, flours, and tubers, amongst others. At the identical time, the consumption of “good” fats is increased.
In such a weight-reduction plan, the intake of carbohydrates shouldn’t represent greater than 10% of the entire calories per day. Due to this, the generation of ketone bodies must be increased.
The symptoms of ketosis
Whether because of weight-reduction plan, metabolic, pathological, or other reasons, because of ketosis changes within the functioning of the organism occurthat are manifested through various signs. The most important ones are the next:
- Weakness
- Headaches
- Lack of appetite
- Bad breath (halitosis)
- Constant feeling of thirst
- occasional nausea and vomiting
- increased frequency of urination
- Constipation or, conversely, diarrhea
- The feeling of a bitter or metallic taste within the mouth
Particularly, bad breath is experienced or perceived during fasting. Nevertheless, this and other symptoms may disappear after a number of days, once the body adapts to the keto weight-reduction plan, for instance.
Alternatively, increased ketone bodies will be detected in urine and blood tests. It’s considered ketosis when their concentration is above 0.5 mmol/L.
Nevertheless, this could vary in keeping with the extent of hydration. There may even be false negatives.
Is ketosis helpful?
The means of ketosis provides sufficient energy for the body to operateeach physically and mentally. Now, because of this of fasting or a low-carbohydrate weight-reduction plan, the body can begin to burn stored fat.
This is nice news for people who find themselves obese or obese. For that reason, there are studies that claim that ketogenic diets can improve cardiovascular health by reducing body fat percentages.
Ketosis has been related to a reduced risk of developing various sorts of cancerespecially by reducing tumor size, in keeping with some studies on the topic. On this sense, glucose is taken into account to be a food for cancer cells.
Ketogenic diets have also been found to supply advantages within the prevention and treatment of type 2 diabetesimproving the glycemic profile, insulin sensitivity, and plasma levels of glycosylated hemoglobin.
The usage of ketogenic diets to treat neurological conditionsreminiscent of epilepsy,is in an experimental phase. And although research reports positive results, the mechanism of neuroprotective motion remains to be not very clear.
The health consequences of ketosis
Nevertheless, ketosis also carries health risks. On this respect, because of a metabolic disorder, when the body is unable to expel the ketone bodies, the blood concentrations of ketone bodies rise.
Metabolic acidosis can then occur. And if the blood becomes too acidic, it affects organ function, resulting in coma and death.
Studies describe other health consequences of ketosis:
- Gastrointestinal disturbances: this includes constipation, nausea, and increased incidences of gastroesophageal reflux.
- Metabolic changes: this includes increased serum cholesterolhypocalcemia, hypomagnesemia, low carnitine, anemia, and deficiencies of selenium, copper, and other minerals.
- Bone alterations: ketosis may interfere with phosphocalcic and vitamin D metabolism, increasing the chance of developing osteopenia and suffering fractures.
- Cases of renal lithiasis, pancreatitis, and vesicular lithiasis have been described.
Nevertheless, there are some ideas surrounding ketosis that haven’t any basis. For instance, there isn’t any evidence that the keto weight-reduction plan affects hair loss.

Be very careful with fad diets
The ketogenic weight-reduction plan will be very restrictive, so the body will suffer in some unspecified time in the future, either throughout the adaptation or if it’s prolonged in time. It’s due to this fact advisable not to increase it beyond 2 or 3 monthseven with interruptions.
Alternatively, the ketogenic weight-reduction plan is contraindicated in certain cases. These include people over 65 years of age, pregnant or breastfeeding women, patients with liver or kidney failure, heart problems, a history of stroke, or gallstones.
Ketosis brings advantages, but additionally complications. It shouldn’t be taken evenly. Subsequently, it’s price remembering that this and another weight-reduction plan must be done under the guidance and accompaniment of a health skilled.
