Keto Bhb: Does It Really Work For Weight Loss?

Beta-hydroxybutyrate (BHB) is a chemical produced by the body when it is in a state of ketosis. It is one of the three physiological ketones produced by the liver when the body is burning fat for energy instead of glucose. BHB is the predominant ketone body, making up about 80% of the total circulating ketones in our blood.

BHB can also be made in a lab and taken as a supplement. It is often marketed as an exogenous ketone supplement that can help people get into ketosis more quickly and experience its benefits, such as weight loss and improved athletic performance.

However, there is limited research on the effectiveness of exogenous BHB supplements, and some evidence suggests that they may even hinder weight loss efforts. Furthermore, BHB supplements are often sold as keto salts, which can lead to excessive sodium consumption and have been linked to side effects like stomach discomfort and diarrhoea.

While BHB supplements may provide some benefits, more research is needed to determine their effectiveness and safety, especially for long-term use.

BHB's role in weight loss

Beta-hydroxybutyrate (BHB) is a ketone body produced by the liver from fat for energy when glucose is not available. It is one of three "physiological" ketones produced by the body, the other two being acetoacetate and acetone. BHB is the predominant ketone body, making up about 80% of the total circulating ketones in our blood.

BHB is a clean-burning energy source for the body and brain. It can be produced through endogenous ketosis, which is when the body produces ketone bodies without support from a ketone supplement, or exogenous ketosis, which is achieved through the use of exogenous ketones like ketone esters or ketone salts.

BHB can be used to achieve a metabolic state of ketosis, curb carbohydrate cravings, reduce appetite, and speed up weight loss. It can also help relieve or prevent the "keto flu," which includes symptoms such as fatigue, hunger, and mental cloudiness.

BHB has several benefits, including:

• Reduced feelings of hunger
• Improved mental performance
• Increased physical performance
• Longer-lasting energy
• Reaching ketosis faster
• Minimizing or preventing "keto flu" symptoms
• Enhanced immune health

BHB can be supplemented through ketone salts or ketone esters. Ketone salts are ketones bound to a salt, typically sodium, potassium, calcium, or magnesium, and are usually found in powder form. Ketone esters are ketones linked to another compound called an ester and are packaged in liquid form.

While ketone supplements are generally considered safe, there is limited research on their long-term effects. Some potential side effects include nausea, diarrhea, and stomach discomfort. Additionally, the high amounts of minerals in ketone supplements, particularly ketone salts, can lead to excessive mineral consumption, which may have detrimental effects.

Overall, BHB plays a crucial role in weight loss by providing an alternative energy source for the body and brain, curbing appetite, and speeding up the process of reaching ketosis.

BHB's impact on athletic performance

Beta-hydroxybutyrate (BHB) is a chemical produced by the body when it doesn't have enough glucose to burn for energy. It can also be made in a laboratory and taken as a supplement. BHB is one of the three "physiological" ketones produced by the liver.

BHB has been linked to improved athletic performance, particularly in endurance sports. It is thought that BHB can provide an additional source of fuel for the body, allowing athletes to switch between burning fats and carbohydrates for energy.

However, recent research suggests that BHB supplements may not improve athletic performance and could even worsen it. A study published in the International Journal of Sport Nutrition and Exercise Metabolism found that highly trained endurance athletes who took a BHB supplement performed worse in cycling tests than those who took a placebo. The researchers suggested that this may be due to the effect of ketone ingestion on blood pH balance, heart rate, and perceived fatigue during exercise.

More research is needed to fully understand the impact of BHB supplements on athletic performance, particularly in other types of endurance tests and in strength-based exercises. While BHB may provide some benefits for athletes, it is important to note that there are also potential downsides, and more research is needed to fully understand the effects of BHB on exercise performance.

BHB's effect on brain health

Beta-hydroxybutyrate (BHB) is a chemical produced by the body that provides energy when not enough carbohydrates or sugars have been eaten. It can also be made in a laboratory and taken as a supplement. BHB has been observed to have a positive effect on brain health.

BHB is one of the three "physiological" ketones produced by the body, specifically in the liver. It is the predominant ketone body circulating throughout the body, making up about 80% of the total circulating ketones in our blood. BHB is a clean-burning energy source for the body and the brain. It can cross the blood-brain barrier to provide energy for the brain, ensuring cognitive function under food-deprived conditions.

BHB has been observed to trigger the release of neurotrophic factors, or chemicals that support the health of neurons. It enhances the expression of a molecule known as brain-derived neurotrophic factor (BDNF), which is associated with cognitive enhancement as well as reduced anxiety and depression. BHB also helps increase the synthesis of GABA, an inhibitory neurotransmitter that is needed for proper brain health.

BHB has also been shown to have an anti-inflammatory effect, which is crucial for the brain. Chronic inflammation is a known factor in various neurological disorders, so reducing inflammation can protect the brain from neuroinflammation. Improved endothelial function enhances blood flow to the brain and ensures better delivery of oxygen and nutrients, which are vital mechanisms for a functioning brain and, therefore, stabilization of mood and cognitive function.

BHB also plays a role in maintaining stable blood glucose levels, which is crucial for brain function. Improved glucose regulation supports cognitive health, reduces the risk of neurodegenerative diseases, helps stabilize mood, and offers overall neuroprotection.

In summary, BHB has been shown to have a positive effect on brain health by providing an alternative energy source, supporting neuronal health, reducing inflammation, and maintaining stable blood glucose levels.

BHB's influence on inflammation

Beta-hydroxybutyrate (BHB) is a chemical produced by the body, which can also be made in a laboratory and taken as a supplement. BHB has been shown to have anti-inflammatory effects via the inhibition of the NLRP3 inflammasome.

The NLRP3 inflammasome is a critical factor in the development of neuro-inflammation, which plays a role in depression. BHB has been shown to reduce levels of interleukin-1β (IL-1β) and tumour necrosis factor-α (TNF-α) in the hippocampus, which are pro-inflammatory cytokines that play a crucial role in the pathophysiology of major depressive disorder (MDD).

BHB also inhibits HDAC5, which has been associated with neuroprotective outcomes, as it helps in blocking pathways leading to cell death.

BHB's role in inflammation and its influence on mental health is an active area of research.

BHB's potential side effects

BHB (beta-hydroxybutyrate) is generally considered safe, but there are some potential side effects to be aware of, especially when taking exogenous BHB supplements.

The most commonly reported side effects of BHB supplements are gastrointestinal issues such as nausea, diarrhoea, constipation, and stomach pain or discomfort. These side effects are more likely to occur when very high doses are used. To avoid these symptoms, it is recommended to start with a low dose and gradually increase the amount over time.

Another potential side effect of BHB supplements is halitosis, or bad breath, due to the production of acetone, which is excreted in the breath. This side effect is usually temporary and can be minimised by staying hydrated and practising good oral hygiene.

Additionally, BHB supplements may cause a decrease in blood pressure, which could be dangerous for individuals who are already on blood pressure medication. It is important to consult with a healthcare professional before taking BHB supplements if you have any medical conditions or are taking other medications.

Furthermore, BHB supplements can exacerbate dehydration, especially if adequate water intake is not maintained. To prevent dehydration, it is recommended to drink at least eight glasses of water per day and consider supplementing with electrolytes.

Lastly, as the body adapts to using BHB for energy, one may experience symptoms such as nausea, fatigue, muscle cramps, and headaches. These symptoms are typically temporary and subside within a few days, but in some cases, they may persist for longer. Again, starting with a low dose and gradually increasing it can help minimise these side effects.
