Keto Bhb: Using Exogenous Ketones For Weight Loss

Beta-hydroxybutyrate (BHB) is a chemical produced by the body to provide energy when it has not consumed enough carbohydrates or sugars. It can also be made in a laboratory and taken as a supplement. BHB is used for dry eye, athletic performance, migraine, Alzheimer's disease, Parkinson's disease, and many other conditions, but there is no good scientific evidence to support these uses.

The ketogenic diet is a very low-carb, high-fat diet that puts your body into ketosis, a nutritional state characterised by raised blood ketones and weight loss. Ketone supplements can mimic ketosis and raise blood ketone levels without changing your diet.

Keto BHB is a supplement that can help with getting you into ketosis faster, more deeply, help control hunger/provide energy, and may assist with bypassing the keto flu. It is not known whether exogenous ketone supplements can help with weight loss.

How does keto BHB affect athletic performance?

The ketogenic diet is a low-carbohydrate, high-fat diet that promotes the production of ketones in the body. Ketones are produced when the body burns fat for fuel instead of carbohydrates. This metabolic state is called ketosis. The impact of a ketogenic diet on athletic performance has been a topic of interest and self-experimentation in recent years.

The ketogenic diet has been found to offer several benefits for athletes, including increased endurance, improved recovery time, enhanced fat burning, and reduced inflammation. By limiting carbohydrate intake, the body is forced to use ketones, produced from fat, as its primary source of fuel. This leads to a reduction in body fat and an increase in lean muscle mass, making it an effective strategy for weight loss and muscle gain.

However, there are also potential drawbacks to the ketogenic diet for athletes. One major concern is the restriction of carbohydrate intake, which is the primary fuel source for high-intensity exercise. This can lead to decreased energy levels and impaired performance during workouts. Additionally, the ketogenic diet can cause dehydration and electrolyte imbalances, resulting in muscle cramps and decreased endurance. It is worth noting that it can take several weeks for the body to adapt to using fat as its primary fuel source, which may initially cause a drop in performance.

Exogenous ketone supplements have been suggested as a way to support a ketogenic diet or to achieve the benefits of ketosis without strict adherence to the diet. These supplements can help raise blood ketone levels, mimicking the state of ketosis. However, it is important to note that ketone supplements are not a quick fix, and more research is needed to understand their effectiveness fully.

In conclusion, while the ketogenic diet can offer benefits for athletic performance, it may not be suitable for all athletes, especially those engaged in high-intensity, short-duration sports. It is important for athletes to carefully consider the potential benefits and drawbacks and consult with healthcare professionals and registered dietitians before incorporating it into their training regimen.

What are the side effects of keto BHB?

While keto BHB is generally considered safe, there are some side effects to be aware of.

One of the most common side effects of taking keto BHB is gastrointestinal distress. This can include stomach upset, constipation, diarrhoea, stomach pain, and nausea. These side effects are more likely to occur when very high doses are used. To avoid this, it is recommended to start with a smaller dose and gradually increase to the full amount. Taking BHB with other fats, such as MCT oil, can also help to slow down absorption and reduce gastrointestinal distress.

Another potential side effect is a decrease in athletic performance. One study found that athletes performed worse on high-intensity cycling and running tasks after four days on a ketogenic diet compared to those on a high-carb diet.

Additionally, there is a risk of developing keto flu when starting a ketogenic diet, which can include symptoms such as exercise tolerance difficulties, constipation, headaches, bad breath, muscle cramps, and diarrhoea.

Furthermore, there is a possibility of dehydration when following a ketogenic diet, as the body loses water before losing fat. Dehydration can lead to symptoms such as dark-coloured urine and increased thirst.

It is important to note that the long-term effects of exogenous ketone supplements are still unknown, and they may not be suitable for everyone. Individuals with certain conditions, such as eating disorders, fat metabolism disorders, liver failure, or thyroid problems, should avoid the keto diet.

Can keto BHB help with weight loss?

The keto diet is a high-fat, low-carb diet that promotes weight loss by pushing the body into a state of ketosis, where it burns stored fat for energy instead of glucose. Ketosis can be challenging to achieve and maintain, but supplements like keto BHB can help.

Beta-hydroxybutyrate (BHB) is a chemical produced by the body when it is in a state of ketosis. It can also be made in a lab and taken as a supplement. BHB provides an alternative energy source for the body, including the brain, and is thought to be responsible for the weight loss associated with the keto diet.

Taking BHB as a supplement can help kick your body into ketosis faster and increase the amount of fat burned for energy. It can also reduce hunger, improve focus, and increase energy levels. BHB is often marketed as "keto salts" or "keto esters" and is typically consumed in powder or capsule form.

While BHB can be beneficial for weight loss, it is important to note that there is limited research on its long-term effects. Additionally, BHB supplements are not a substitute for a healthy diet and should be used in conjunction with a balanced keto diet and regular exercise for optimal weight loss results.

What are the benefits of keto BHB for the brain?

Beta-hydroxybutyrate (BHB) is a chemical that is produced by the body when it is low on carbohydrates or sugars. It can also be made in a laboratory and taken as a supplement. BHB has been linked to several health benefits, particularly for the brain. Here are some of the key benefits of keto BHB for the brain:

Enhances Cognitive Function

BHB is an essential fuel source for the brain when sugar levels are low. It can easily cross the blood-brain barrier and provide the brain with up to 70% of its energy needs. BHB improves cognitive function by acting as a neuroprotective antioxidant, increasing mitochondrial efficiency, improving the balance of neurotransmitters, and encouraging the growth of new neurons and neuronal connections.

Reduces Risk of Neurodegenerative Diseases

BHB has been found to protect the brain by reducing inflammation and oxidative stress, which are common factors in many neurodegenerative diseases. Studies suggest that BHB may be beneficial in preventing and treating Alzheimer's disease, Parkinson's disease, and other forms of dementia.

Boosts Memory

Low-carb diets, like the keto diet, have been shown to boost memory retention and preservation in old age. The presence of BHB, one of the ketones produced during ketosis, improves memory function.

Improves Mental Health

The keto diet has been linked to improved mental health. It is a proven method for weight loss, which can have a positive impact on body image and self-esteem. Additionally, the low-carb diet helps stabilise hormones, reducing the rollercoaster emotions that can impact mental health.

Increases Longevity

BHB has been found to increase longevity by reducing inflammation and optimising gene expression. It blocks the insulin-like growth factor (IGF-1) receptor gene, which is linked to excessive cell growth and early death. BHB also activates the FOXO3a gene, which is associated with increased longevity by boosting antioxidant production.

How does keto BHB affect blood sugar?

Beta-hydroxybutyrate (BHB) is one of the three ketone bodies produced by the liver when it is low on carbs. The other two are acetoacetate and acetone. BHB is the most abundant ketone in the body, making up around 78% of ketones in the blood.

When the body does not have enough glucose available for energy, it starts using stored fat for energy. This process, called ketogenesis, produces ketone bodies.

Ketone levels are measured by testing the level of BHB in the bloodstream. A BHB level between 0.5 and 1.0 mmol/L is considered "light nutritional ketosis", while a level between 1.0 and 3.0 mmol/L is considered "optimal" ketosis.

Exogenous ketones are supplements that can help the body stay in ketosis by raising blood levels of ketone bodies. They are typically taken in the form of BHB salts or ketone esters.

Several studies have found that exogenous ketone supplementation can lower blood sugar levels. One study found that participants who drank a ketone ester supplement had lower blood sugar levels. Another study of individuals with type 2 diabetes found that consuming a ketone monoester drink for one month led to a significant decrease in all glycaemic control markers, including blood glucose.

The glucose-lowering effect of exogenous ketones may be due to several mechanisms. One potential mechanism is that BHB stimulates the release of insulin, which helps regulate blood sugar levels. Another mechanism is that BHB can inhibit lipolysis, reducing the amount of nonesterified fatty acids in the blood. This, in turn, can lead to reduced gluconeogenesis and lower hepatic glucose output.

Overall, exogenous ketone supplementation, especially with ketone monoesters, appears to be a promising approach to lower blood sugar levels, particularly for individuals with type 2 diabetes or prediabetes. However, more research is needed to fully understand the effects of exogenous ketones on blood sugar regulation.
