Keto Supplements: Do They Work For Weight Loss?

The ketogenic or keto diet is a very low-carb, high-fat diet. The diet is challenging to follow, and one of the biggest challenges is getting into and maintaining ketosis. This has led to the creation of keto supplements, which claim to boost energy, burn fat, and aid weight loss. But do they work?

Keto supplements typically contain two active ingredients: ketone beta-hydroxybutyrate (BHB) and medium-chain triglycerides (MCTs). BHB is a compound that the liver produces from fats, and MCTs are a type of fat found in coconut and palm oil. These supplements claim to increase ketone levels, helping you achieve ketosis faster and lose weight.

While there is some research to support the use of keto supplements, specifically for epilepsy and mental health, there is limited evidence for their effectiveness in weight loss. Some studies even suggest that they may hinder weight loss efforts. Additionally, the Food and Drug Administration (FDA) does not regulate the exogenous ketone supplement market, so there is a chance of contamination or misleading marketing.

Overall, while keto supplements may provide some benefits, there is insufficient evidence to support their use as a weight loss aid.

Ketone supplements may decrease appetite

Ketone supplements have been shown to decrease appetite, which may help with weight loss. In a study of 15 people of normal weight, participants who drank a beverage containing ketone esters experienced 50% less hunger after an overnight fast than those drinking a sugary beverage. This effect was attributed to lower levels of the hunger hormone ghrelin between two and four hours after drinking the ketone ester drink.

However, ketone supplements may not affect appetite as much in people who have eaten a meal beforehand. Studies have observed higher blood ketone levels in those who didn't eat a meal before taking a ketone supplement compared to those who did. This is because elevated ketones are associated with reduced appetite and lower ghrelin levels, and so ketone supplements may only be beneficial during a fast rather than after a meal that contains carbs.

One small study found that exogenous ketone supplements reduced appetite for over four hours, which could be promising for weight loss. However, more studies are needed before ketone supplements can be recommended for appetite control. While ketone supplements may decrease appetite, there is insufficient evidence to support their use as a weight loss aid.

Ketone supplements may cause side effects

In addition to these adverse effects, ketone supplements have also been shown to cause a poor aftertaste. Furthermore, achieving ketosis with ketone salts is not recommended due to the high amounts of minerals consumed. For example, one serving of ketone salts provides 680 mg of sodium, 320 mg of magnesium, and 590 mg of calcium. However, to maintain ketosis, multiple servings per day are required, which means these numbers quickly double or triple.

The side effects associated with ketone supplements range from stomach discomfort to diarrhea. Because these supplements are also bound to salts, consuming too many can be dangerous.

It is worth noting that there is a lack of long-term studies on the effects of ketone supplements. As a result, their potential impact on health over time is still unknown.

Keto pills are not FDA-approved

The keto diet is a very low-carb, high-fat diet that is challenging to follow. As a result, keto supplements have been created to help boost energy, burn fat, and lose weight fast. However, it is important to note that keto pills are not FDA-approved.

The Food and Drug Administration (FDA) does not approve dietary supplements, including vitamins, minerals, herbs, and keto products. This means that there is a chance that what is listed on the label of a supplement may not be accurate, and the product may even contain heavy metals and other contaminants. This is a cause for concern, as it can pose health risks to consumers.

In fact, the FDA has issued warnings about certain weight loss products that have been found to contain hidden ingredients. These products may contain active drug ingredients not listed on the labels, including prescription drugs, which can cause potentially serious side effects and interact with other medications or supplements. One specific example is the FDA's warning about keto supplements containing hidden traces of gluten, which can cause severe reactions in people with gluten intolerance.

Additionally, there is limited research on the efficacy of keto supplements. While some studies suggest that ketone supplements can help achieve ketosis quicker and may decrease appetite, others indicate that they may hinder weight loss efforts. As a result, there is insufficient evidence to support the claim that keto pills help with weight loss.

Furthermore, side effects from keto supplements are also a red flag. These can include gastrointestinal distress, nausea, vomiting, abdominal pain, and diarrhea. Some people may also experience constipation, headache, bad breath, muscle cramps, and other symptoms associated with the "keto flu."

Therefore, it is recommended to proceed with caution when considering keto supplements. While they may be marketed as a natural way to boost weight loss, there are potential risks and unknown long-term effects associated with their use. It is always advisable to consult with a healthcare professional before taking any supplements, especially if you have any health concerns or are taking other medications.

Keto supplements may be contaminated

Keto supplements are not approved by the Food and Drug Administration (FDA). This means that the FDA does not test or evaluate these supplements for safety, purity, or effectiveness. Therefore, there is a chance that keto supplements may be contaminated and contain heavy metals and other contaminants.

According to a registered dietitian nutritionist, Diana Guevara, "It’s very expensive, and there’s a chance for them to be contaminated, so for me, it’s a lose-lose-lose all around."

If you decide to purchase keto supplements, it is recommended that you opt for products that have been tested and certified by third-party organizations, such as the National Sanitation Foundation, ConsumerLab.com, and U.S. Pharmacopeia. These third-party organizations can verify that the contents of the supplement match what is listed on the label. However, it is important to keep in mind that while third-party tests can check for ingredients, they do not assess their effectiveness.

Keto supplements are not a substitute for a keto diet

Keto supplements are often marketed as a way to sustain ketosis and enhance the effects of a keto diet. While these supplements may provide some benefits, they are not a substitute for a well-formulated keto diet. Here are some reasons why keto supplements should not be relied on as a replacement for a keto diet:

• Lack of Research and Evidence: There is limited peer-reviewed research and evidence to support the effectiveness of keto supplements in weight loss or ketosis. Most of the claims made by supplement manufacturers are not backed by robust scientific studies.
• Potential Health Risks: Some keto supplements may even be harmful to your health in the long run. For example, ketone supplements can cause side effects such as gastrointestinal distress, nausea, vomiting, abdominal pain, and diarrhea. Additionally, if your ketone blood levels become too high, it can make your blood dangerously acidic.
• Ineffectiveness in Weight Loss: While keto supplements may help increase ketone levels in the blood, they may not necessarily lead to weight loss. In fact, some studies suggest that high ketone levels may hinder weight loss rather than enhance it. The body has a feedback mechanism that slows down the production of ketones when they become excessively high.
• Expense and Contamination: Keto supplements can be expensive, and there is a chance for them to be contaminated with heavy metals or other contaminants. This is because dietary supplements, including keto products, are not approved or regulated by the Food and Drug Administration (FDA).
• Keto Flu: Keto supplements claim to help alleviate the symptoms of "keto flu," which includes issues like leg cramps and dehydration. However, there is no evidence to support that keto pills can effectively prevent or treat keto flu. These symptoms typically resolve on their own as your body adjusts to the diet.
• Proper Nutrition: A keto diet involves a specific ratio of macronutrients, such as high fat intake and very low carbohydrate consumption. Keto supplements cannot replicate this nutritional profile and may not provide the same benefits as a well-balanced keto diet.
• Individual Variation: The effectiveness of keto supplements may vary from person to person. While some people may experience enhanced ketosis or mild benefits, others may not see any positive effects at all. This variability underscores the importance of a customized diet plan that takes into account individual needs and responses.

In conclusion, while keto supplements may provide some support during a keto diet, they should not be relied on as a substitute for a well-formulated and balanced keto diet. It is always advisable to consult with a healthcare professional or a registered dietitian before starting any new dietary supplement or making significant changes to your diet.
