Amino Keto: Does It Work For Weight Loss?

Amino acids are the building blocks of our bodies and are classified into three types: essential, non-essential, and conditional. They can be further categorised depending on the type of intermediates they form during their metabolism. These 20 amino acids are further classified into ketogenic amino acids, glucogenic amino acids, or both.

Ketogenic amino acids are amino acids that are broken down to form ketone bodies. They can be converted to water-soluble compounds called ketone bodies, which, along with fatty acids, provide energy when glucose is insufficient in the body, a process called ketogenesis.

Ketogenic amino acids follow the ketogenic metabolic pathway, where the amino acid is introduced into the body, degraded into water-soluble ketone bodies, and transported in the body for energy.

Examples of ketogenic amino acids include Lysine and Leucine. Lysine is found in meats, peas, beans, and fish, and helps metabolize fatty acids into energy. Leucine is found in peanuts, soybeans, lentils, and beef, and helps in the production of energy in the muscles and the promotion of protein synthesis.

Ketogenic amino acids can be used as a fuel source in the body and can be used to gain muscle, reduce weight, and help with exercise performance.

Ketogenic Amino Acids and Weight Loss

The ketogenic diet is an extremely low-carbohydrate diet that encourages the body to burn fat more efficiently. The body's preferred source of fuel is carbohydrates, but it can also run on fat. When the body does not have access to significant quantities of glucose from carbohydrates, it switches to burning fat. This metabolic state is called ketosis.

Ketogenic amino acids can help the body enter ketosis. Amino acids are the building blocks of proteins, which are necessary nutrients for most cell and organ functions. Consuming the right amount of protein in the correct proportion to fat can facilitate ketosis. Ketogenic amino acids can convert to acetyl-CoA, a precursor of ketone bodies, whereas glucogenic amino acids degrade to glucose.

In humans, leucine and lysine are exclusively ketogenic amino acids. Phenylalanine, isoleucine, threonine, tryptophan, and tyrosine are both ketogenic and glucogenic. The remaining thirteen amino acids are exclusively glucogenic.

Ketogenic amino acids have been shown to aid weight loss by increasing the body's fat-burning capacity and decreasing levels of insulin, a hormone that encourages fat storage. They also help to decrease appetite, making it easier to stick to meal plans.

In addition to aiding weight loss, ketogenic amino acids have been studied for their potential to treat non-alcoholic fatty liver disease and diabetes. They have also been shown to improve cognitive skills and mental clarity, boost energy and endurance, and enhance digestive health.

Ketogenic Amino Acids and the Ketogenic Diet

Ketogenic amino acids are a subset of amino acids that cannot be converted to glucose. Instead, they are degraded directly into acetyl-CoA, which is the precursor of ketone bodies and myelin. In humans, leucine and lysine are exclusively ketogenic, while five other amino acids are both ketogenic and glucogenic: phenylalanine, isoleucine, threonine, tryptophan, and tyrosine.

Ketogenic amino acids play important roles in the human body, and ketogenic amino acid-rich (KAAR) diets are being studied as a possible treatment for non-alcoholic fatty liver disease and diabetes. For example, studies have shown that ketogenic diets may aid in decreasing obesity and insulin resistance.

The ketogenic diet is a high-fat, low-carbohydrate diet that encourages the body to burn fat more efficiently. It was originally developed in the 1920s as a treatment for epilepsy, but has since been used to address a range of lifestyle-related chronic conditions, including diabetes and heart disease. The diet involves limiting carbohydrate intake to below a certain threshold while adhering to a high-fat diet, which causes the body to switch from burning carbs for fuel to burning fat.

The ketogenic diet has been shown to have several health benefits, including sustainable weight loss, balanced blood sugar levels, reduced risk of heart disease, heightened cognitive skills and mental clarity, boosted energy and endurance, and better digestion and nutrient absorption.

Ketogenic Amino Acids and Ketone Bodies

Ketogenic amino acids are a subset of amino acids that cannot be converted to glucose and instead give rise to acetoacetic acid. In humans, leucine and lysine are exclusively ketogenic, while five more are both ketogenic and glucogenic: phenylalanine, isoleucine, threonine, tryptophan, and tyrosine. The remaining thirteen amino acids are exclusively glucogenic.

Ketogenic amino acids are a crucial component of the human body, and ketogenic amino acid-rich (KAAR) diets are being studied as a potential treatment for non-alcoholic fatty liver disease (NAFLD) and diabetes. Dietary studies of fatty liver disease in mice show that decreasing the intake of ketogenic amino acids lysine and threonine may induce hepatic steatosis, a significant cause of NAFLD. Leucine, in particular, has been shown to play an important role in the metabolic pathway for insulin through the activation of the rapamycin complex 1 (mTORC1) and protein S6 kinase 1 (S6K1). Overactivation of this pathway leads to insulin resistance.

Ketogenic diets are also being explored as a possible remedy for multiple sclerosis (MS), a condition in which the immune system attacks the myelin sheath that insulates nerves. Ketogenic diets have been shown to alleviate diffuse axonal injury (DAI) in rats. Rats fed a standard diet showed progressive degradation of myelin, with myelin sheaths collapsing or disappearing from injured axons. In contrast, rats fed a ketogenic diet presented axons with thicker myelin.

Ketogenic amino acids can be degraded directly into acetyl-CoA, which is the precursor of ketone bodies and myelin, particularly during early childhood when the developing brain requires high rates of myelin synthesis. This is in contrast to glucogenic amino acids, which are converted into glucose. Ketogenic amino acids cannot be converted to glucose as both carbon atoms in the ketone body are ultimately degraded to carbon dioxide in the citric acid cycle.

Ketogenic Amino Acids and Gluconeogenesis

Ketogenic amino acids are amino acids that can be degraded directly into acetyl-CoA, which is the precursor of ketone bodies and myelin. In humans, leucine and lysine are exclusively ketogenic amino acids, meaning they can only be converted into ketone bodies and not glucose.

Ketogenic amino acids are unable to be converted to glucose as both carbon atoms in the ketone body are ultimately degraded to carbon dioxide in the citric acid cycle. Ketone bodies are particularly important for the developing brain, which requires high rates of myelin synthesis.

Ketogenic diets are being explored as a treatment for multiple sclerosis (MS) as ketone bodies aid in the renewal of myelin. This is because MS is a condition where the immune system attacks the myelin sheath that insulates the nerves.

Leucine, in particular, has been shown to serve an important role in the metabolic pathway for insulin via activation of the rapamycin complex 1 (mTORC1) and protein S6 kinase 1 (S6K1). Over-activation of this pathway leads to insulin resistance.

Ketogenic amino acids can also be used to treat non-alcoholic fatty liver disease (NAFLD) and diabetes. Dietary studies of fatty liver disease in mice show that decreasing the intake of ketogenic amino acids lysine and threonine may induce hepatic steatosis, a major cause of NAFLD.

Gluconeogenesis is the process of converting non-carbohydrate substrates into glucose. This process predominates during catabolysis, rising as fasting and starvation increase in severity. Glucogenic amino acids are amino acids that can be converted into glucose through gluconeogenesis.

Alanine is a glucogenic amino acid that the liver's gluconeogenesis process can use to produce glucose. When blood glucose levels fall, muscle cells break down their protein, releasing alanine, which is then transferred to the liver. Through a transamination process, alanine is changed into pyruvate in the liver. Following this, pyruvate is transformed into oxaloacetate, a crucial step in the gluconeogenesis process. It is possible to synthesize glucose from oxaloacetate, ensuring that the blood glucose levels required for the body to produce energy are maintained.

In summary, ketogenic amino acids are important for the human body as they can be degraded into acetyl-CoA, which is the precursor of ketone bodies and myelin. Ketogenic diets are being explored as a treatment for MS and NAFLD. Glucogenic amino acids, on the other hand, can be converted into glucose through gluconeogenesis, which is particularly important during fasting or starvation.

Ketogenic Amino Acids and Insulin Resistance

Ketogenic amino acids are amino acids that can be degraded directly into acetyl-CoA, the precursor of ketone bodies and myelin. In humans, leucine and lysine are exclusively ketogenic, while five more are both ketogenic and glucogenic: phenylalanine, isoleucine, threonine, tryptophan and tyrosine. The remaining thirteen are exclusively glucogenic.

Ketogenic amino acids play important roles in the human body, and have been studied as a possible treatment for non-alcoholic fatty liver disease (NAFLD) and diabetes. Dietary studies of fatty liver disease in mice show that decreasing the intake of ketogenic amino acids lysine and threonine may induce hepatic steatosis, a major cause of NAFLD. Leucine, in particular, has been shown to serve an important role in the metabolic pathway for insulin via activation of the rapamycin complex 1 (mTORC1) and protein S6 kinase 1 (S6K1) for which over-activation leads to insulin resistance. Further studies illustrate that ketogenic amino acid-rich diets may aid in decreasing obesity and insulin resistance, but their usage remains disputed.
