Keto Diet: How Does Ketosis Work?

The ketogenic diet, or keto diet, is a low-carbohydrate, high-fat eating plan that has been used for centuries to treat specific medical conditions. The keto diet changes the way your body uses food. Typically, carbohydrates in your diet provide most of the fuel your body needs. The keto diet reduces the number of carbs you eat and teaches your body to burn fat for fuel instead. This reduction in carbs puts your body into a metabolic state called ketosis, where the body utilizes fat as its primary fuel source instead of carbohydrates.

The keto diet is high in fat, moderate in protein, and low in carbohydrates

The keto diet is a low-carb, high-fat diet. Typically, 70-80% of a person's calories on the keto diet come from fat, 20-25% from protein, and just 5-10% from carbohydrates.

The keto diet involves drastically cutting down on the number of carbohydrates consumed and replacing them with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes very efficient at burning fat for energy.

On the keto diet, it's important to moderate your protein consumption. This is because protein can be converted into glucose if consumed in high amounts, which may slow your transition into ketosis.

The keto diet is often undertaken to lose weight, as it can help people feel less hungry, which may lead to eating less food. It can also help to lower the risk of certain diseases, such as type 2 diabetes, heart disease, metabolic syndrome, epilepsy, and Alzheimer's disease.

However, the keto diet can have some negative side effects, including nutrient deficiencies, digestive issues, kidney stones, and increased cholesterol. It can also be challenging to maintain due to the restrictive nature of the diet and the limited variety of foods available.

It can help with weight loss

The keto diet can be an effective way to lose weight. It involves eating a very low amount of carbohydrates and replacing them with fat to help your body burn fat for energy. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes incredibly efficient at burning fat for energy.

The keto diet has been shown to be more effective for long-term weight loss than a low-fat diet. One review of 13 studies found that people who followed the keto diet lost an average of 2 pounds more than the group that followed a low-fat diet. Another study in 34 older adults found that those who followed a ketogenic diet for 8 weeks lost nearly five times as much total body fat as those who followed a low-fat diet.

The keto diet can also lead to a reduction in diastolic blood pressure and triglyceride levels. Additionally, the high-fat content of the diet can have a satiating effect, reducing food cravings and decreasing appetite. This can lead to a reduced desire to eat and make it easier to stick to the diet.

Furthermore, the keto diet can help with weight loss by increasing calorie expenditure due to the metabolic effects of converting fat and protein to glucose. It also promotes fat loss versus lean body mass, partly due to decreased insulin levels.

However, it is important to note that the keto diet is very strict and can be challenging to maintain. It may also have some negative side effects, including nutrient deficiencies, digestive issues, and increased risk of kidney stones. Therefore, it is recommended to consult with a physician and a dietitian before starting the keto diet to ensure it is safe and tailored to your individual needs.

It can be used to treat chronic illnesses

The ketogenic diet, or keto diet, is a high-fat, low-carbohydrate, and adequate-protein diet that has been used to treat chronic illnesses. It has been shown to be effective in treating epilepsy and is being studied for its potential benefits in treating other chronic illnesses. Here are some ways in which the keto diet can be used to treat chronic illnesses:

Neurological Disorders

The keto diet has been found to be beneficial in treating neurological disorders such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis (ALS), and epilepsy. It can improve cognitive function, reduce amyloid plaque, and protect against neurodegeneration.

Metabolic Disorders

The keto diet can help manage metabolic disorders such as type 2 diabetes mellitus (T2DM), metabolic syndrome, and polycystic ovarian syndrome (PCOS). It improves insulin sensitivity, reduces blood sugar levels, and promotes weight loss, which are crucial in managing these conditions.

Nonalcoholic Fatty Liver Disease (NAFLD)

NAFLD is a common liver disease characterized by hepatic adiposity. The keto diet has been shown to reduce intrahepatic triglyceride content and improve liver function, potentially reducing the risk of NAFLD.

Cancer

The keto diet may be beneficial in cancer treatment by exploiting the reprogramming metabolism of cancer cells. It can slow tumor growth by limiting glucose availability to tumor cells and enhancing the efficacy of standard treatments.

Cardiac Diseases

The keto diet has been studied for its potential benefits in treating cardiac diseases, particularly heart failure (HF). It can increase the utilization of ketone bodies as an alternative fuel source and improve cardiac function. However, long-term consumption of the keto diet may also increase the risk of cardiovascular disease, so caution is advised.

Inflammatory Diseases

The keto diet has shown promising results in treating inflammatory bowel disease and irritable bowel syndrome by reducing inflammation and improving gut microbiota.

While the keto diet has shown potential in treating various chronic illnesses, it is important to consult a healthcare professional before starting this diet as it may have some side effects and is not suitable for everyone.

It can cause side effects like keto flu

The keto diet is a low-carb, high-fat diet that shares similarities with the Atkins and low-carb diets. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where your body burns fat for energy instead of carbohydrates.

However, one of the most well-publicized complications of ketosis is the "keto flu". The keto flu is a collection of symptoms that can feel similar to the flu and is caused by the body adapting to a new diet consisting of very few carbohydrates. It is important to note that this condition is not recognised by medicine and there is limited understanding of its causes.

The symptoms of keto flu include:

• Headache
• Foggy brain
• Fatigue
• Irritability
• Nausea
• Difficulty sleeping
• Constipation
• Diarrhea
• Stomach or intestinal pain
• Sugar cravings
• Cramping
• Muscle soreness
• Dizziness
• Poor focus and concentration

The keto flu can last from a few days to several weeks, and in extreme cases, up to a month. However, it is important to note that not everyone will experience the keto flu, as some people are naturally "metabolically flexible".

To manage the symptoms of keto flu, it is recommended to:

• Drink plenty of water to stay hydrated
• Avoid strenuous exercise and opt for light activities like walking or yoga
• Replace electrolytes by salting food to taste and including potassium-rich, keto-friendly foods like leafy greens and avocados
• Get enough sleep and reduce caffeine intake
• Eat enough fat and carbohydrates to reduce cravings and keep you feeling satisfied
• Cut out carbs slowly over time, instead of all at once

It has been used to treat epilepsy

The ketogenic diet has been used to treat epilepsy since the 1920s. It is usually considered for children with seizures that do not respond to medications. The diet is also sometimes started to help reduce or stop anti-seizure drugs, though this does not always occur. In such cases, the diet is used in partnership with drugs to help reduce seizures. The ketogenic diet is not recommended as a primary anti-seizure option because patients are often averse to drastic changes in their food intake or have trouble staying on the diet due to its strict requirements and potential side effects like nausea, constipation, and fatigue.

Several studies have shown that the ketogenic diet does reduce or prevent seizures in many children whose seizures could not be controlled by medications. Over half of the children who go on the diet have at least a 50% reduction in the number of their seizures. Some children, usually 10-15%, even become seizure-free. The diet has been shown in many studies to be particularly helpful for some epilepsy conditions, including infantile spasms, Rett syndrome, tuberous sclerosis complex, Dravet syndrome, Doose syndrome, and GLUT-1 deficiency.

The ketogenic diet is a high-fat, low-carbohydrate diet. The name "ketogenic" means that it produces ketones in the body. Ketones are formed when the body uses fat for its source of energy. Usually, the body uses carbohydrates for its fuel. Because the ketogenic diet is very low in carbohydrates, fats become the primary fuel instead. The body can work very well on ketones and fats.

The ketogenic diet is a strict diet. It is usually used in children because the restricted food choices make it hard for adults to follow. The diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis. When this happens, your body becomes very efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.

The ketogenic diet is a medical treatment and should only be followed with the support of an experienced epilepsy specialist and dietitian. It is prescribed by a physician and carefully monitored by a dietitian. The diet is usually started in the hospital, with the child fasting (except for water) under close medical supervision for 18-24 hours. The diet is then started, either by slowly increasing the calories or the ratio.
