Keto Weight Loss Supplements: Effective Or Just Hype?

The ketogenic diet is a high-fat, low-carbohydrate diet that has become popular in recent years due to its purported effects on weight loss. The keto diet was originally introduced in 1920 to help treat children with epilepsy who did not respond to traditional medication. While the diet may provide weight-loss benefits, it can also be challenging to follow consistently. As a result, some people have turned to keto supplements to help them stay in ketosis, the state in which the body burns fat instead of carbohydrates for fuel. However, there is limited research on the effectiveness of keto supplements, and they may even be harmful in the long run. This article will explore the real use of keto weight loss supplements and whether they are necessary or beneficial for achieving weight loss.

Ketone supplements may decrease appetite

Ketone supplements, also known as exogenous ketones, are often used by those following a ketogenic diet to increase blood ketone levels. The idea is that these supplements can help you reach ketosis quicker, where your body burns fat instead of carbohydrates for fuel.

One of the purported benefits of ketone supplements is that they may decrease appetite. In a study involving 15 people of normal weight, participants who drank a beverage containing ketone esters experienced 50% less hunger after an overnight fast than those who drank a sugary drink. This effect was attributed to lower levels of the hunger hormone ghrelin between two and four hours after consuming the ketone ester drink.

However, it's important to note that ketone supplements may not affect appetite as much in people who have eaten a meal beforehand. Studies have shown that ketone supplements increase blood ketone levels more in those who didn't eat a meal before taking the supplement compared to those who did. This is because the body is using fewer ketones as fuel when there is more available glucose from carbohydrates.

While ketone supplements may decrease appetite, it's worth mentioning that there is limited research on their effectiveness in this area. Additionally, the long-term effects of these supplements are unknown, and they may even be harmful in the long run. As with any supplement, it's always a good idea to consult with your doctor before adding them to your diet.

Ketone supplements are not a substitute for a keto diet

Ketone supplements are typically available in powder or capsule form and contain two specific ingredients: medium-chain triglycerides (MCTs) and exogenous ketones or ketone salts. MCTs are predominantly saturated fats that break down in the liver, while exogenous ketones are ketones made outside of the body in a lab. These ingredients work together to increase the amount of fat in the body and kick it into ketosis faster. Ketone supplements also allegedly block carbs from being absorbed or metabolized.

However, the effectiveness of ketone supplements is questionable. While they can temporarily elevate ketone levels in the blood, the overall impact on the body is not the same as achieving ketosis through dietary choices. Additionally, ketone supplements can be expensive and may cause side effects such as stomach discomfort, nausea, and diarrhea. Furthermore, the Food and Drug Administration (FDA) does not regulate the ketone supplement market, so there are concerns about their safety, purity, and effectiveness.

While ketone supplements may have their benefits, they should not be relied upon as a substitute for the keto diet. The keto diet itself can be challenging to follow due to its restrictive nature, but it is important to understand that ketone supplements are not a magic pill for weight loss or ketosis. They may have a role in supporting a keto diet, but they cannot replace the dietary changes required to achieve and maintain ketosis.

Ketone supplements may cause side effects like nausea and stomach discomfort

Ketone supplements are often used by people on the keto diet to increase blood ketone levels and kick their body into ketosis, a state where the body burns fat instead of carbohydrates for fuel. However, while ketone supplements can be beneficial, they may also cause some adverse side effects.

One of the most common side effects of ketone supplements is stomach discomfort, which can manifest as nausea, abdominal pain, and increased bowel movements. In one study, 13 out of 19 participants who consumed ketone salts experienced gastrointestinal distress. This is a significant number, considering that ketone salts are one of the most common forms of ketone supplements, along with ketone esters.

The stomach discomfort caused by ketone supplements may be due to the high amounts of minerals they contain. For example, a single serving of ketone salts can provide 680 mg of sodium, 320 mg of magnesium, and 590 mg of calcium. To maintain ketosis, multiple servings of ketone supplements are needed throughout the day, which can lead to an excessive intake of these minerals.

Furthermore, ketone supplements can also cause electrolyte imbalances, which can be dangerous for individuals with kidney disease or other conditions that affect their ability to regulate electrolytes. Electrolytes are essential for the proper functioning of muscles and the maintenance of a regular heart rhythm. Therefore, an imbalance can have serious health consequences.

In addition to stomach discomfort and electrolyte imbalances, ketone supplements have also been associated with other side effects such as dehydration, hypoglycemia, and hypertension. Dehydration is a common issue on the keto diet, and taking ketone supplements can heighten this effect. Hypoglycemia, or low blood sugar, can be dangerous for individuals with diabetes, especially if they are taking medications that lower blood glucose levels. Finally, ketone salts, which are a common form of ketone supplement, usually contain sodium, which could be harmful to individuals with high blood pressure.

While ketone supplements may be beneficial for individuals on the keto diet, it is important to be aware of the potential side effects and take them with caution. It is always a good idea to consult a healthcare professional before starting any new supplement, especially if you have any existing health conditions or are taking medications.

Ketone supplements may be beneficial for people with neurodegenerative conditions

Ketosis-evoked neuroprotective effects may lead to an improvement in health status and delay both aging and the development of related diseases through improving mitochondrial function, antioxidant and anti-inflammatory effects, histone and non-histone acetylation, beta-hydroxybutyrylation of histones, modulation of neurotransmitter systems, and RNA functions.

Administration of EKSs may be a safe and effective alternative metabolic therapy to the ketogenic diet. EKSs can generate rapid and mild to moderate therapeutic ketosis. EKSs can be well-tolerated and safe, with mild adverse effects, if any. Moreover, the administration of EKSs can circumvent both dietary restrictions and adverse effects of ketogenic diets (e.g., nephrolithiasis, constipation, and hyperlipidemia).

EKSs have been demonstrated to evoke beneficial effects on CNS diseases, including anti-seizure and anti-epileptic effects, anxiolytic influence, regeneration of nervous system injuries, and alleviating effects on neurodegenerative diseases such as Alzheimer's disease. These beneficial effects are induced likely through ketosis-evoked neuroprotective effects, for example, by improved mitochondrial functions, enhanced ATP levels, decreased inflammatory processes, and decreased oxidative stress.

Additionally, ketone bodies may modulate aging processes, thereby extending lifespan and delaying the development of age-related diseases, such as neurodegenerative diseases. In fact, it has been demonstrated that not only ketogenic diets but also the administration of EKSs can increase and maintain blood ketone body levels. Ketone bodies, such as beta-hydroxybutyrate (BHB), may promote anti-aging effects. Moreover, it was demonstrated that BHB, as an endogenous ligand molecule, can activate the hydroxycarboxylic acid receptor 2 (HCAR2 or GPR109A receptor). HCAR2 receptors are expressed not only in macrophages but also in the brain cells, mainly in microglia, as well as astrocytes and neurons. Thus, the BHB molecule, via, for example, HCAR2 receptors, can modulate not only physiological but also pathophysiological processes in the brain that are connected to aging and neurodegenerative diseases.

Based on the literature, the increase of BHB level may be the main factor contributing to the beneficial effects on aging, lifespan, and age-related diseases after the administration of EKSs. Indeed, it has been demonstrated that BHB decreased the senescence-associated secretory phenotype (SASP) of mammals and extended the lifespan of C. elegans. Consequently, in this review paper, we focused on BHB-generated alleviating effects. Although limited evidence supports the alleviating influence of EKSs on lifespan, aging processes, and related CNS diseases, we can hypothesize that EKSs-evoked increases in blood BHB levels can modulate (alleviate) aging processes and improve symptoms of age-related diseases through their neuroprotective effects, therefore delaying both aging and the development of related diseases and extending lifespan.

Ketone supplements may not aid weight loss

Ketone supplements are often marketed as a quick solution to achieving weight loss. However, it is important to examine the evidence behind these claims and understand the potential risks associated with their use.

Firstly, it is worth noting that ketone supplements are not subject to the same rigorous testing and regulation as pharmaceutical drugs. The Food and Drug Administration (FDA) does not regulate the exogenous ketone supplement market, and there is limited peer-reviewed research on their long-term effects. This lack of comprehensive research means that the potential benefits of ketone supplements for weight loss are largely unknown.

While ketone supplements have been shown to increase blood ketone levels and mimic the state of ketosis achieved through a ketogenic diet, this does not necessarily translate to enhanced weight loss. A 2021 study found that consuming ketone supplements for six weeks enhanced ketosis in participants following a keto diet, but there were no significant differences in weight loss or health benefits compared to those who did not take the supplements. This suggests that ketone supplements may not enhance weight loss when paired with a keto diet.

Additionally, ketone supplements may even hinder weight loss efforts. Ketones contain calories, with a single serving of exogenous ketone salts typically containing less than 100 calories. To maintain a state of ketosis, multiple servings per day are required, which can be costly. Furthermore, if ketone blood levels become too high, the blood can become dangerously acidic. As a result, a feedback mechanism in healthy individuals slows down the production of ketones, potentially preventing body fat from being used as fuel.

Ketone supplements have also been associated with several side effects, including nausea, vomiting, abdominal pain, and diarrhoea. These side effects can be red flags and may cause discomfort or other health issues. Therefore, it is essential to consult a doctor before taking any nutritional supplements, especially if you have any underlying health conditions.

In conclusion, while ketone supplements may temporarily elevate blood ketone levels, there is insufficient evidence to support their effectiveness in aiding weight loss. Some research even suggests that they may hinder weight loss efforts. As such, it is important to approach these supplements with caution and not rely on them as a quick fix for weight loss.
