Why is ketosis good

One of the main criticisms of this diet is that many people tend to eat too much protein and poor-quality fats from processed foods, with very few fruits and vegetables. Patients with kidney disease need to be cautious because this diet could worsen their condition. Additionally, some patients may feel a little tired in the beginning, while some may have bad breath, nausea, vomiting, constipation, and sleep problems.

We have solid evidence showing that a ketogenic diet reduces seizures in children, sometimes as effectively as medication.

However, there are no human studies to support recommending ketosis to treat these conditions. Weight loss is the primary reason my patients use the ketogenic diet. Previous research shows good evidence of a faster weight loss when patients go on a ketogenic or very low carbohydrate diet compared to participants on a more traditional low-fat diet, or even a Mediterranean diet. However, that difference in weight loss seems to disappear over time. A ketogenic diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term.

There is even more controversy when we consider the effect on cholesterol levels. A few studies show some patients have increase in cholesterol levels in the beginning, only to see cholesterol fall a few months later.

For ketosis to start, you generally need to eat fewer than 50 grams of carbs per day and sometimes as little as 20 grams per day. However, the exact carb intake that will cause ketosis varies between individuals. When eating a very low carb diet, levels of the hormone insulin go down and fatty acids are released from body fat stores in large amounts. 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. Ketosis is a metabolic state where ketones become an important source of energy for the body and brain. This happens when carb intake and insulin levels are low. However, a large portion of your brain can also use ketones for energy, such as during starvation or when your diet is low in carbs 7. In addition, your body can use protein or other molecules to produce the glucose the brain still requires during ketosis.

This process is called gluconeogenesis. The glucose it still needs can be produced from protein or other sources. While ketosis is part of normal metabolism, ketoacidosis is a dangerous metabolic condition that can be fatal if left untreated. In ketoacidosis, the bloodstream is flooded with extremely high levels of glucose blood sugar and ketones.

Ketoacidosis is most often associated with uncontrolled type 1 diabetes. It may also occur in people with type 2 diabetes, although this is less common In addition, severe alcohol abuse may lead to ketoacidosis Most people with epilepsy use anti-seizure medications to help manage seizures. It has primarily been used in children, with some studies showing benefits.

Many children with epilepsy have seen significant reductions in seizures while following a ketogenic diet, and some have seen complete remission 15 , 16 , 17 , The ketogenic diet is a popular weight loss diet, and research has shown it can be effective Some studies have found that ketogenic diets are more helpful for weight loss than low fat diets 20 , 21 , One study reported 2.

For this reason, it is generally not necessary to count calories on this diet 24 , Some individuals may find it easy to adhere to the ketogenic diet, while others may find it unsustainable. Some research suggests that the keto diet may not be the best way to lose weight. The authors of a review concluded that it was not better than other diets at helping people lose weight, and it may not have specific advantages for people with metabolic disorder A person can test for ketoacidosis using a kit at home.

Ketosis does not usually occur in people who eat balanced diets and regular meals. Drastically reducing calorie and carb intake, exercising for extended periods, or being pregnant may trigger ketosis. Although some people choose to put the body through ketosis, the risk of increased acid levels can be dangerous in those who are not controlling it.

In people with diabetes, ketosis and eventually DKA can occur if they do not use enough insulin, if they skip meals, or if an insulin reaction occurs. An insulin reaction usually happens while asleep.

Doctors consider DKA an emergency, as it can lead to a diabetic coma and even death. Emergency healthcare workers will usually administer treatment followed by hospitalization in an intensive care unit.

In otherwise healthy people, following a healthful, balanced diet and exercising regularly can help prevent ketosis. People with diabetes should keep an eye on their ketone levels with a test kit, particularly when ill or under stress.

Many studies have demonstrated the powerful weight loss effects of a low carb, or keto, diet. However, this diet can be difficult to maintain and may cause health problems in people with certain conditions, such as type 1 diabetes. DKA is a particularly dangerous complication of ketosis that can occur when ketosis makes the blood too acidic. Emergency treatment is necessary for people experiencing DKA. Most people can try the keto diet safely. However, it is best to discuss any significant changes to diet with a dietitian or doctor.

This is especially the case in those with underlying conditions. A runner's diet should contain a healthy balance of macronutrients, adequate carbohydrates, and micronutrients from plant foods.
