Keytones And Keto: Friend Or Foe?

Ketones are energy molecules created by the liver from the breakdown of fats. The body makes ketones when it doesn't have access to carbohydrates or enough glucose stores. Ketones are used as an alternative fuel source by the body when glucose stores are in short supply. The keto diet is a low-carb, high-fat diet that aims to force the body into using ketones for fuel instead of sugar from carbohydrates. This metabolic state is called ketosis. While ketosis can be beneficial for weight loss and certain health conditions, it also comes with serious risks and should not be attempted without consulting a doctor.

Ketones are produced by the liver when the body doesn't have enough glucose for fuel

Ketones are energy molecules created by the liver when the body doesn't have enough glucose for fuel. This process is called ketogenesis. During ketogenesis, the body burns through its fat stores, releasing fatty acids that are then transported to the liver and converted into ketones. The main ketone bodies are acetoacetate (AcAc) and beta-hydroxybutyrate (BHB), while the third and least abundant is acetone (Ace).

The body can enter a state of ketogenesis and start producing ketones for various reasons. One of the most common reasons is following a ketogenic (keto) diet, which involves drastically reducing carbohydrate intake and replacing it with fat. When on a keto diet, the body becomes very efficient at burning fat for energy, and it also turns fat into ketones in the liver, which can supply energy for the brain.

Another reason the body may produce ketones is during periods of fasting or exercise, when there is not enough glucose readily available for fuel. In these cases, the body will break down fats for energy, releasing ketones as a byproduct.

Having ketones in the blood is generally safe and indicates that the body is using its backup energy source - fats. However, if the level of ketones becomes too high, it can lead to a condition called ketoacidosis, which is life-threatening and requires immediate treatment. This is more common in people with Type 1 diabetes, but it can also occur in people with Type 2 diabetes or those with alcohol use disorder.

Ketones are an alternative fuel source for the body and brain

Ketosis can be induced by following a ketogenic (keto) diet, which involves drastically reducing carbohydrate intake and replacing it with fat. During ketosis, the body breaks down fats for energy, releasing ketones that are used to fuel the body's tissues and brain.

The liver produces three types of ketones: beta-hydroxybutyric acid (BHB), acetoacetate (AcAc), and acetone (Ace). BHB is the most abundant and effective type of ketone for energy production.

Exogenous ketone supplements, typically made from BHB, can be used to boost ketone levels in the body and help induce ketosis. These supplements are often marketed as a weight-loss aid, as ketosis can lead to increased fat burning and reduced appetite. However, it is important to note that the FDA does not regulate ketone supplements for their purity, safety, and effectiveness, and they may cause side effects such as stomach distress and electrolyte imbalance.

Overall, ketones provide an alternative fuel source for the body and brain when glucose is in short supply. This can occur during ketosis, induced by a keto diet or other factors such as fasting or exercise.

Ketone supplements can be used to boost ketone levels in the body

Exogenous ketone supplements are a great tool for getting into ketosis faster and priming your body to use fat for energy. They directly impact ketosis by increasing your body's beta-hydroxybutyrate (BHB) ketone levels. BHB is the main energy source your body runs on and is considered a "superfuel". Taking a BHB ketone drink can support a healthy keto lifestyle, including your workouts, mental performance, and energy levels.

Ketone supplements are especially useful when you are just starting a keto diet as they can help reduce keto flu symptoms such as headaches, brain fog, fatigue, and body aches. They allow you to transition into ketosis sooner and more comfortably. Additionally, since exogenous ketone drinks mimic ketosis, they suppress your appetite, which helps with weight loss.

Ketone supplements may have side effects such as stomach distress and electrolyte imbalance

Ketone supplements are generally safe, but they can cause some side effects. One of the possible side effects is stomach distress, which may manifest as digestive discomfort, nausea, and diarrhea. People who experience these symptoms should start with a low dose and gradually increase it while monitoring how they feel.

Another potential side effect of ketone supplements is electrolyte imbalance. This is because ketone salts contain the minerals sodium, potassium, magnesium, and calcium. Consuming large amounts of these minerals may lead to an electrolyte imbalance, resulting in symptoms such as muscle cramps, muscle weakness, difficulty sleeping, and restlessness. Therefore, it is important to be cautious and consult a healthcare professional when taking ketone supplements, especially for individuals with kidney disease or other conditions that affect electrolyte balance.

Ketosis is a metabolic state in which the body uses fat for fuel instead of carbohydrates

The keto diet is a low-carb, high-fat diet that aims to force the body into ketosis. In ketosis, the body becomes very efficient at burning fat for energy, using ketones as its main energy source. This can lead to weight loss and other potential health benefits, such as improved mental clarity and reduced inflammation.

However, it's important to note that the keto diet is restrictive and may not be suitable for everyone. It can also be difficult to stick to in the long term. Additionally, there are risks associated with the diet, including nutrient deficiencies, liver and kidney problems, constipation, and fuzzy thinking. Therefore, it's crucial to consult a doctor and a registered dietitian before starting a ketogenic diet.

Exogenous ketone supplements are available to help support ketosis and enhance its benefits. These supplements provide the body with ketones, which can be used for energy. However, it's important to note that the FDA does not regulate ketone supplements for purity, safety, and effectiveness. As such, it's recommended to speak to a doctor before taking any supplements.
