Keto Supplements: How Do They Work?

The ketogenic diet is a very low-carb, high-fat diet that has been popular for many years. It works by tricking the body into thinking it's fasting, triggering it to break down fat into ketones for energy – also known as ketosis. There has been a recent increase in the number of supplements, or keto diet pills, on the market claiming to cause the same effect. But do they work?

Ketone supplements may decrease appetite

Ketone supplements have been shown to decrease appetite, which may help you lose weight by eating less. However, there is limited research on the effects of ketone supplements, and they may even hinder weight loss.

The Science Behind Ketone Supplements and Appetite

Ketone supplements, also known as exogenous ketones, are produced synthetically outside the body. They can be consumed as a dietary supplement to achieve ketosis and weight loss. Ketosis is a state where the body switches from using glucose to ketone bodies for fuel, resulting in weight loss.

A study involving 15 participants found that those who consumed a ketone-rich drink after an overnight fast experienced a 50% decrease in hunger compared to those who consumed a sugary drink. This effect lasted for up to four hours and was attributed to lower levels of the hunger hormone ghrelin.

Factors Affecting Appetite Suppression

However, it is important to note that ketone supplements may not affect appetite as much if consumed after a meal. Studies have shown that ketone supplements are more effective at suppressing appetite when taken during a fast or when consumed without a meal. Additionally, the effects of ketone supplements on appetite may be short-lived, requiring multiple doses throughout the day to maintain their potential benefits.

Safety and Effectiveness of Ketone Supplements

While ketone supplements can temporarily elevate ketone levels in the blood, their overall impact on the body is not the same as achieving ketosis through dietary means. There is limited peer-reviewed research on the effectiveness and safety of ketone supplements, and they may cause side effects such as nausea, vomiting, abdominal pain, and diarrhoea.

Furthermore, the body seeks to maintain a safe level of ketones to prevent a toxic buildup in the bloodstream. When ketone levels are high, the liver stops producing ketones and tries to flush out the excess through urine, a process called ketonuria. This means that ketone supplements may not be effective for weight loss, as the body will simply eliminate the excess ketones.

In conclusion, while ketone supplements may decrease appetite, more research is needed to determine their effectiveness and safety. They should not be relied upon as a weight-loss solution and should only be used in conjunction with a healthy diet and exercise.

Ketone supplements may not be effective for weight loss

Ketone supplements are claimed to put your body into ketosis without having to follow a ketogenic diet. However, there is little evidence to support this claim.

A 2021 study found that people with obesity who followed a low-calorie ketogenic diet and took 24 grams of a BHB salt supplement per day for six weeks experienced enhanced ketosis. However, having higher levels of ketones in the blood did not seem to boost weight loss when compared to other groups, such as those following only the keto diet without the supplement.

Another study found that exogenous ketone supplements may decrease appetite for over four hours when taken in a fasted state, but other research suggests that they may hinder weight loss efforts.

Ketone supplements are also expensive, costing upwards of $3 per serving. They can also be harmful to your health in the long run, as there is limited peer-reviewed research to support their use.

Overall, there is insufficient evidence to support the use of ketone supplements for weight loss. While they may help to increase ketone levels in the blood, this does not necessarily lead to increased weight loss. Therefore, ketone supplements cannot be recommended for weight loss at this time.

Ketone supplements may have negative side effects

Ketone supplements can also cause electrolyte imbalances, which can be dangerous for people with medical conditions that affect their ability to regulate electrolytes, such as kidney disease. Additionally, the ketogenic diet can cause dehydration, and taking ketone supplements may heighten this effect.

Furthermore, hypoglycaemia is a potential side effect of ketone supplements, especially for those with diabetes who take medications that lower blood glucose levels. Ketone salts, which are commonly found in ketone supplements, usually contain sodium, which could be dangerous for people with high blood pressure.

It is important to note that the Food and Drug Administration (FDA) does not regulate the ketone supplement market, and there is limited research on the long-term effects of these supplements. Therefore, it is recommended to consult a doctor before taking any ketone supplements to assess their safety and potential side effects.

Ketone supplements may be costly

Ketone supplements are costly compared to other dietary supplements. The cost of regular use can pile up over time, depending on the brand and dosage, making them less affordable for some people.

The price of ketone supplements is driven by the cost of research and development, as well as the need for high-quality ingredients and manufacturing processes. The development of new formulations, improved taste profiles, and scientific validation all contribute to the expense. The cost of regular use can be a burden for some consumers, especially those who require high doses or long-term supplementation.

In addition, the demand for these supplements is high, which can also drive up prices. The popularity of the ketogenic diet and the desire for quick and easy weight loss solutions have led to a growing market for ketone supplements. The companies producing these supplements are often smaller startups that lack the economies of scale of larger supplement manufacturers, which can also contribute to higher prices.

Furthermore, the regulatory environment for dietary supplements can impact pricing. The Food and Drug Administration (FDA) does not approve dietary supplements, including ketone supplements, before they enter the market. This means that supplement manufacturers do not have to go through rigorous testing and evaluation processes, which can keep costs down. However, it also means that consumers are taking on additional risk, as the safety and effectiveness of these supplements may not have been adequately evaluated.

It is worth noting that while ketone supplements may be expensive, they are not necessarily effective or safe. There is limited research on the long-term effects of ketone supplementation, and some studies have shown that they may not enhance weight loss or provide other claimed benefits. In addition, ketone supplements can cause side effects such as digestive issues and electrolyte imbalances, which can be serious for individuals with certain medical conditions.

Overall, the high cost of ketone supplements is a significant factor for consumers to consider, especially given the lack of strong evidence for their effectiveness and the potential for harmful side effects.

Ketone supplements may not be necessary

While ketone supplements are claimed to put your body into ketosis without having to follow a ketogenic diet, there is little evidence to support this. In fact, some evidence suggests that they may even hinder weight loss.

The Case Against Ketone Supplements

Ketone supplements are typically marketed as a way to achieve and sustain ketosis, a state in which your body burns fat for fuel instead of glucose. However, there is limited research on the efficacy of these supplements, and they may not be safe for everyone.

One of the main issues with ketone supplements is that they can prevent your body from producing its own ketones. Additionally, because ketones contain calories, taking ketone supplements may not be worthwhile for weight loss, especially considering the cost.

Furthermore, there is a risk of contamination with dietary supplements as the Food and Drug Administration does not approve them. There is also a chance of scams with some keto products, especially those heavily pushed on social media.

The Bottom Line

Keto supplements are unnecessary and possibly even harmful. If you're considering the keto diet, it's important to ask yourself if it's really worth it, as very restrictive diets are hard to follow and not sustainable. Instead of relying on supplements, it's better to fill your plate with foods that contain lots of healthy fats and round out your meals with non-starchy vegetables.
