What is ketosis and is healthy?

Ketosis is a natural metabolic state.

This is the production of body fat ketone bodies, and their use for energy instead of carbohydrates.

You can enter ketosis following a very low-carbohydrate, high-fat ketogenic diet ( 1 ).

addition rapid weight loss , ketosis can have several health benefits , such as reduced epileptic seizures in children ( 2 ) .

Ketosis is quite complex, but this article explains what it is and how you can benefit.

What is ketosis?

Ketosis is a metabolic condition in which fat provides much of the fuel for the body.

occurs when there is limited to glucose (blood sugar) access, which is the preferred method for many cells in the body fuel source.

Ketosis is associated more with ketogenic and very low-carb diets . hunger ( 3 4 5 6 [19459006alsooccursduringpregnancylactation fast and ]).

To enter ketosis, people generally need to eat less than 50 grams of carbohydrates per day and sometimes as low as 20 grams per day.

This requires the elimination of certain foods from your diet, such as grains, sweets and sugary drinks. You also have to cut back on vegetables, potatoes and fruit.

By eating a very low-carbohydrate diet, the levels of hormone insulin down and fatty acids are released from fat stores of the body in large quantities.

Many of these fatty acids are transferred to the liver, where they are oxidized and converted to ketones (or ketone bodies). These molecules can provide energy for the body.

Unlike fatty acids, ketones can cross the blood-brain barrier and provide energy for the brain in the absence of glucose.

Conclusion: Ketosis is a metabolic state where ketones become the main sources of energy for the body and brain. This occurs when the intake of carbohydrates and insulin levels are very low.

Ketones can provide energy for the brain

is a common misconception that the brain does not function without carbohydrates.

It is true that glucose is preferred and there are some cells in the brain can only use glucose as fuel.

However, a large part of your brain can also use energy ketones, such as during starvation or when your diet is low in carbohydrates ( 7 ).

Indeed, after only three days of fasting, the brain receives 25% of its energy from ketones. During long-term hunger this number to about 60% ( 8 9 ) rises.

In addition, your body can use proteins to produce shortages still requires glucose to the brain during ketosis. This process is called gluconeogenesis .

Ketosis and gluconeogenesis are fully capable of meeting the energy needs of the brain.

Conclusion: When the brain is not getting enough glucose, can be used ketones to get power. The still needs little glucose can be produced from proteins.

Ketosis is not the same as ketoacidosis

People often confuse ketosis and ketoacidosis.

While ketosis is part of normal metabolism, metabolic ketoacidosis is a dangerous condition that can be fatal if untreated.

In ketoacidosis, blood circulation is flooded with extremely high levels of glucose (blood sugar) and ketones.

When this happens, the blood becomes acidic, which is seriously harmful.

Ketoacidosis is most often associated with type 1 diabetes uncontrolled. It can also occur in people with type 2 diabetes, although this is less common ( 10 ).

In addition, abuse of alcohol can lead to severe ketoacidosis ( 11 ).

Conclusion :. Ketosis is a natural metabolic state, while ketoacidosis is more often serious medical condition seen in type 1 uncontrolled diabetes

Effects on epilepsy

epilepsy is a brain disorder characterized by recurrent seizures.

is a very common neurological disease, which affects about 70 million people worldwide ( 12 ).

For most patients, anticonvulsant medications can help control seizures. However, about 30% of patients continue to have seizures despite using these drugs ( 13 ).

In early 1920, the ketogenic diet was introduced as a treatment for epilepsy in people who do not respond to drug treatment ( 14 ).

has primarily been used in children, with some studies showing significant benefits. Many epileptic children have had massive reductions in seizures in a ketogenic diet, and some have even been complete remission ( 15 16 17 18 ).

Conclusion :. ketogenic diets can effectively reduce epileptic seizures, especially in children with epilepsy who do not respond to conventional treatment

Effects on weight loss

the ketogenic diet is a popular diet weight loss is well supported by science ( 19 ).

Indeed, many studies found that ketogenic diets lead to greater weight loss than low-fat diets ( 20 21 , 22 ).

One study reported 2.2 times more weight loss for people who follow a ketogenic diet, compared with those with a low fat, low calorie diet ( 23 ) .

What is more, people tend to feel less hungry and fuller in a ketogenic diet, which is attributed to ketosis. For this reason, it is generally not necessary count calories on this diet ( 24 25 ).

Conclusion: Studies show that ketogenic diets lead to greater weight loss than low-fat diets. In addition, people feel less hungry and more complete.

Other health benefits of ketosis

Ketosis and ketogenic diets may also have other therapeutic effects. Are now being studied as a treatment for a wide variety of conditions ( 26 ):

• Heart disease. Reducing carbohydrates ketosis levels may improve risk factors for heart disease and blood triglycerides, total cholesterol and HDL cholesterol ( 27 28 ).
• type 2 diabetes The diet can improve insulin sensitivity by up to 75%, and some diabetics are able to reduce or even stop diabetes medications ( 29 30 ).
• metabolic syndrome. ketogenic diets can improve all symptoms of metabolic syndrome, including high triglycerides, excess belly fat and high blood pressure ( 31 ).
• Alzheimer's disease. A ketogenic diet may have benefits for patients with Alzheimer's disease ( 32 ).
• Cancer. Some studies suggest that ketogenic diets can help in cancer therapy, possibly helping to "starve" cancer cells glucose ( 33 34 ).
• Parkinson's disease. A small study found that symptoms of Parkinson's disease improved after 28 days with a ketogenic diet ( 35 ).
• acne. There is some evidence that this diet can reduce the severity and progression of acne ( 36 ).

Conclusion :. Ketosis and ketogenic diets can help with a number of chronic diseases, including metabolic syndrome, type 2 diabetes and Alzheimer's disease

Is ketosis any of these negative health effects ?

There are some potential side effects that may arise from ketosis and ketogenic diets.

These include headache, fatigue, constipation, high cholesterol levels and bad breath ( 37 38 ).

However, most symptoms are temporary and should disappear within a few days or weeks.

kidney stones addition, some epileptic children have developed in the diet ( 39 , 40 , 41 ).

Though extremely rare, there have been some cases of women in breastfeeding develop ketoacidosis probably caused by a low-carbohydrate or ketogenic diet ( 42 43 , 44 ).

People taking medicine to lower blood sugar should consult a doctor before trying a ketogenic diet, because diet can reduce the need for medication.

Everything that is said, ketosis is generally safe for healthy people.

However, not everyone. Some people may feel good and energetic in ketosis, while others feel miserable.

Conclusion: Ketosis is safe for most people. However, some people may experience side effects, including bad breath, headaches and constipation.
