Keto Weight Loss Pills: Do They Work?

Keto weight loss pills are nutritional supplements designed to help your body achieve or maintain ketosis. The keto diet is a low-carb, high-fat approach to weight loss that is widely popular but challenging to follow. It involves getting 90% of your calories from fat, 6% from protein, and only 4% from carbohydrates.

Keto supplements typically contain two active ingredients: Ketone beta-hydroxybutyrate (BHB) and Medium-chain triglycerides (MCTs). BHB is a compound produced by the liver from fats, which then circulates in the bloodstream and is used up by the body's tissue for energy. MCTs are a type of fat found in coconut and palm oil that can be used as an energy source during ketosis.

While keto pills may help you achieve ketosis, there is little evidence that they directly cause weight loss. Additionally, the safety and efficacy of supplements, including keto weight loss pills, are not FDA-approved, and there is a risk of contamination or health concerns with some products.

Ketone beta-hydroxybutyrate (BHB)

BHB is used to provide energy when the body does not have enough carbohydrates or sugars to burn for energy. It is also thought to help the brain and nerves work better and may provide energy to muscles to improve exercise ability.

BHB is available as a supplement in the form of ketone salts and ketone esters. Ketone salts are more common and accessible, consisting of synthetic ketones bound to an electrolyte such as magnesium, sodium, or calcium. They come in the form of pills, powders, and drinks. Ketone esters, on the other hand, are considered more powerful but are more expensive and have a strong taste.

BHB supplements are often used by people following a ketogenic or low-carb diet to help them achieve and maintain ketosis, a state where the body burns fat for energy instead of carbohydrates. While BHB supplements can help achieve ketosis, they do not directly cause weight loss.

Some potential benefits of BHB supplements include appetite suppression and controlling blood sugar levels. However, it is important to note that the safety and efficacy of these supplements have not been evaluated by the FDA, and they may cause side effects such as stomach upset, especially at very high doses.

Medium-chain triglycerides (MCTs)

MCTs are more easily broken down by the body into molecules called ketone bodies, which can be used for energy. This is why they are often used as part of the high-fat, low-carb ketogenic (keto) diet. MCTs can help the body reach the fat-burning state of ketosis faster, as they are more quickly absorbed into the bloodstream and used for energy. They can also be converted into ketones in the liver, which can be used as an energy source for the brain.

MCTs have been linked to lower calorie intake and reduced body weight and waist circumference. They may also help to reduce insulin resistance and improve cognition in people with Alzheimer's disease. Additionally, MCTs have antimicrobial and antifungal effects and may help manage skin infections.

However, there are some potential drawbacks to MCTs. They are high in calories and may increase the risk of heart disease by increasing "bad" LDL cholesterol. They may also stimulate the release of hunger hormones and lead to fat buildup in the liver.

Ketone salts

While ketone supplements may have benefits, such as reducing appetite, they have not been shown to directly cause weight loss in human studies. In fact, some evidence suggests that they may even hinder weight loss by inhibiting fat breakdown and providing additional calories. Therefore, while ketone salts may be a helpful tool for some, they should not be relied upon as a sole method for weight loss.

Ketone esters

Research on ketone esters is limited, but they may have unpleasant side effects. A small 2012 study by the University of Oxford found that participants experienced negative consequences such as nausea and dizziness after taking ketone esters.

MCT oil

• Weight loss and fat burn: MCT oil has been found to increase fat oxidation, resulting in greater body fat loss compared to olive oil. It can also increase thermogenesis, the metabolic process where the body burns calories to generate heat, leading to a higher calorie burn.
• Appetite regulation: Studies have shown that MCT oil may help reduce appetite and calorie consumption, which can aid in weight loss.
• Exercise endurance: MCTs can raise ketone levels in the body, providing more energy for low-impact exercises.
• Insulin sensitivity: MCT oil may help improve insulin sensitivity, which is often an issue for people who are overweight or obese.
• Improved cholesterol levels: MCT oil can help lower LDL ("bad") cholesterol while increasing HDL ("good") cholesterol.
• Neurological benefits: MCT oil may help manage epilepsy, Alzheimer's disease, and autism by providing an alternative energy source for the brain.
• Antimicrobial and antifungal properties: MCTs have been shown to fight the growth of yeast and bacteria, including Candida albicans, a common yeast that can cause infections.

However, it is important to note that while MCT oil has these potential benefits, more research is needed to confirm its efficacy. Additionally, MCT oil is very calorie-dense, and consuming too much can lead to weight gain and other negative side effects. Therefore, it is recommended to start with small amounts and gradually increase the dosage over time.
