Keto 800 Powder: Does It Really Work For Weight Loss?

Powdered keto supplements are claimed to help people sustain ketosis and lose weight. However, there is little evidence to support these claims. The US Food and Drug Administration does not approve dietary supplements, so there is a chance that what is in the bottle is not what is on the label. Additionally, there is a risk of contamination, and side effects can include stomach discomfort and diarrhoea. Some people also report that these supplements have a poor aftertaste.

Exogenous ketone supplements may decrease appetite

Exogenous ketone supplements are synthetic sources of ketones that can be consumed orally. They are often marketed as a quick fix to a non-keto-friendly meal, claiming to help the body stay in ketosis and burn fat instead of carbohydrates. However, the effectiveness of these supplements is questionable, and they may even hinder weight loss efforts.

Appetite Suppression

Ketone supplements have been shown to decrease appetite, which may aid in weight loss by reducing calorie intake. A study on 15 participants with normal weight found that those who consumed a beverage containing ketone esters experienced 50% less hunger after an overnight fast compared to those who drank a sugary beverage. This effect was attributed to lower levels of the hunger hormone ghrelin 2 to 4 hours after consuming the ketone ester drink.

However, it is important to note that ketone supplements may not have the same impact on appetite if consumed after a meal. Studies suggest that higher blood ketone levels are observed when supplements are taken on an empty stomach compared to after a meal. This is because elevated ketone levels are associated with reduced appetite and lower ghrelin levels, and the body may use fewer ketones as fuel when there is an adequate supply of glucose from carbohydrates.

Weight Loss Claims

While ketone supplements may suppress appetite, their potential weight loss benefits are uncertain. In fact, some evidence suggests that they may hinder weight loss. The purpose of the ketogenic diet is to produce ketones from stored fat as an alternative fuel source. However, if ketone blood levels become too high, the body has a feedback mechanism that slows down ketone production. As a result, taking ketone supplements may prevent the body from using stored fat as fuel, at least in the short term.

Additionally, ketone supplements themselves contain calories, with about 4 calories per gram, similar to carbohydrates and protein. To maintain a state of ketosis, multiple servings of these supplements may be required throughout the day, which can be costly. Furthermore, the long-term effects of these supplements are unknown, and they may cause side effects such as nausea, diarrhea, and stomach discomfort.

Ketone supplements may not affect appetite if you've eaten a meal beforehand

Ketone supplements are claimed to increase ketone levels in the body, which may aid weight loss. However, their effectiveness is questionable, and they may even hinder weight loss efforts.

Ketone supplements have been shown to decrease appetite, which may help reduce calorie intake and promote weight loss. However, this effect appears to be influenced by the consumption of meals. Ketone supplements have been found to decrease appetite by 50% in people who consumed them after an overnight fast. In contrast, their appetite-suppressing effect was diminished in individuals who had eaten a meal beforehand. This suggests that the elevated ketone levels induced by the supplements may not be high enough to significantly affect appetite when other fuel sources, such as carbohydrates from a meal, are available.

Furthermore, ketone supplements may not be necessary for weight loss. The body naturally produces ketones when it breaks down fat for fuel, and ketone supplements are intended to enhance this process. However, the body has a feedback mechanism that slows down ketone production when blood ketone levels become too high. As a result, taking ketone supplements may prevent the body from using its fat stores for fuel, at least in the short term. Additionally, ketone supplements provide calories, and maintaining ketosis typically requires multiple servings per day, which can be costly.

While ketone supplements may help induce ketosis, they are not a magic pill for weight loss. A calorie-restricted diet and regular exercise remain the most effective strategies for healthy and sustainable weight loss.

Ketone supplements are unlikely to be effective for weight loss

Ketone supplements are synthetic ketones, known as exogenous ketones, that come in the form of pills, powders, or gummies. They are marketed as a quick way to induce ketosis and achieve weight loss. However, the human body can also naturally produce ketones when it breaks down fat for fuel, a process called ketosis. Ketosis occurs when the body switches from using glucose to ketone bodies for fuel.

The claim that exogenous ketones induce ketosis faster is supported by multiple studies. For example, one study showed that supplementing with 11 grams of beta-hydroxybutyrate (BHB), a type of ketone, increased blood BHB levels by over 300%. However, the effects of exogenous ketones are often short-lived, lasting only a few hours. This means that multiple doses per day may be needed to maintain ketosis.

Despite the potential appetite-curbing effects of ketone supplements, there is limited evidence that they aid weight loss. Ketones themselves contain calories, with about four calories per gram, the same as carbohydrates or protein. Additionally, the body has a feedback mechanism that slows down the production of ketones if their levels become too high, which may prevent body fat from being used as fuel.

Furthermore, there is mixed evidence regarding the impact of exogenous ketones on athletic performance, with some studies showing no impact or even impaired performance. While ketone supplements may be beneficial for certain medical conditions, such as epilepsy, and are being considered for the treatment of other neurological disorders, their effectiveness for weight loss is questionable.

Ketone supplements may be beneficial for athletic performance

Ketone supplements are claimed to increase ketone levels in the body, which can be used as an alternative source of energy. However, there is little evidence to support the claim that ketone supplements can help with weight loss or athletic performance. In fact, some studies suggest that they may even hinder weight loss.

Ketone supplements are also marketed to help with the "keto flu", a group of flu-like symptoms that can develop within a week of switching to a keto diet. However, there is no evidence to support this claim either.

Ketone supplements are not approved by the Food and Drug Administration (FDA) and may contain heavy metals and other contaminants. They are also expensive and may be harmful to the liver.

Overall, there is insufficient evidence to support the use of ketone supplements as a weight loss or athletic performance aid.

Ketone supplements may be beneficial for psychiatric disorders and epilepsy

Ketone supplements, such as ketone salts or ketone esters, can generate rapid and sustained nutritional ketosis and metabolic changes, which may have therapeutic effects on central nervous system (CNS) disorders, including psychiatric diseases. Ketone supplements elevate blood levels of the ketone bodies: D-β-hydroxybutyrate (βHB), acetoacetate (AcAc), and acetone. These compounds, either directly or indirectly, beneficially affect the mitochondria, glycolysis, neurotransmitter levels, activity of free fatty acid receptor 3 (FFAR3), hydroxycarboxylic acid receptor 2 (HCAR2), and histone deacetylase, as well as functioning of NOD-like receptor pyrin domain 3 (NLRP3) inflammasome and mitochondrial uncoupling protein (UCP) expression.

The downstream cellular and molecular changes resulting from ketone supplements may lead to a reduction in the pathophysiology associated with various psychiatric disorders. Supplement-induced nutritional ketosis leads to metabolic changes and improvements, such as in mitochondrial function and inflammatory processes. Therefore, the development of specific adjunctive ketogenic protocols for psychiatric diseases should be actively pursued.
