Keto Weight Loss Pills: Are They Safe?

Keto weight loss pills, also known as exogenous ketones, are dietary supplements that claim to help people lose weight by sending their bodies into a state of ketosis. Ketosis is a metabolic state where the body burns fat instead of glucose for energy, and it is typically achieved through a low-carb, high-fat ketogenic diet. While keto pills can increase ketone levels in the blood, there is limited evidence to support their effectiveness for weight loss. In fact, some experts suggest that they may even hinder weight loss efforts by impairing the body's ability to use fat as fuel. Additionally, the lack of regulation in the supplement market raises concerns about the safety and accuracy of these products. As such, it is essential to consult a healthcare professional before taking any dietary supplements or embarking on a restrictive diet.

Keto pills are not the same as the keto diet

Keto pills are a type of diet pill that claims to send your body into a state of ketosis to aid rapid weight loss. Ketosis is a metabolic process where your body burns fat instead of glucose for energy. While keto pills can increase ketone levels in the blood, this does not mean they can help you lose weight.

Keto pills are often used by people who don't want to cut out carbs. However, it is the elevated ketones that are associated with reduced appetite. There is evidence that keto pills are only beneficial while fasting rather than after a carb-heavy meal or snack. This indicates that the body uses fewer ketones for fuel because the glucose from carbs is already available.

Keto pills lack the additional benefits you get from eating a ketogenic diet, such as lower insulin levels. "A ketogenic diet does more than just stimulate ketone production," notes Barbara Gower, a professor of nutrition sciences at the University of Alabama at Birmingham. "Ketogenic diets also lower circulating insulin, and often glucose, which arguably may have more benefit than the ketones themselves."

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

Ketone supplements are often used by people who don't want to cut out carbs from their diet. While ketones are associated with reduced appetite, this effect is observed only in people who haven't eaten a meal before taking the supplement. This is because the body uses fewer ketones for fuel when there is available glucose from the carbs.

Studies have shown that ketone supplements can decrease appetite by 50% in people who haven't eaten beforehand. However, the effect is diminished in those who have eaten a meal containing carbs. This is because the body prioritises glucose as fuel, meaning fewer ketones are used, and the blood ketone levels remain lower.

Ketone supplements are thought to be most effective when taken during a fast, such as upon waking in the morning, or before exercise. This is because ketone supplements work by increasing the level of ketones in the blood, which is harder to achieve when there is already available glucose in the body.

Therefore, while ketone supplements may be beneficial for weight loss by suppressing appetite, they are most likely to be effective when taken on an empty stomach.

Keto pills are not FDA-approved

The FDA has warned consumers about certain weight loss products that have been found to contain hidden ingredients and may pose a significant health risk. Some keto supplements have been recalled due to the presence of gluten, which can cause serious or life-threatening reactions in people with gluten intolerance. There is also a risk of scams with some keto products, especially those heavily promoted on social media.

Keto pills are not the same as the full keto diet, and taking these shortcuts can prevent you from achieving your health goals. Research has shown that higher levels of exogenous ketones in the bloodstream can make the liver turn down its own production. This can affect how your body metabolizes food for fuel. Keto pills may also not work if you don't cut out carbs, as the elevated ketones associated with reduced appetite are only beneficial while fasting.

Keto pills are limited in that they only increase ketones in the blood and only when you are also following a highly restricted ketogenic diet. The ketogenic diet offers additional benefits that keto pills lack, such as lower insulin levels. Experts say that a wholesome and effective diet doesn't have shortcuts; it has well-rounded, healthy meals made with real food.

Keto pills are not regulated

The Food and Drug Administration does not approve dietary supplements, including vitamins, minerals, herbs, and keto products. This means that it is difficult to know whether you are getting what you pay for. Dietary supplements are regulated post-market, meaning they are sold to consumers without oversight of their safety or weight-loss claims.

"Just like any other supplement, keto pills are not regulated and must be purchased by a reputable brand that is tested by a third party," says registered dietitian Ariana Fiorita.

Because supplements are not monitored by the FDA, you have to trust that your chosen supplement contains the advertised levels of its active ingredient.

Keto pills are unlikely to speed up fat adaptation

However, since taking exogenous ketones decreases lipolysis, it is unlikely to speed up fat adaptation and, consequently, lessen the amount of fat burned to achieve and maintain ketosis. Ketone supplements may prevent your body from using fat as fuel and delay the body's transition into ketosis. The body is an efficient machine, and it has feedback mechanisms to prevent ketone levels that can make your blood too acidic. Ketone supplements are also only beneficial while fasting rather than after a carb-heavy meal or snack. This indicates that the body uses fewer ketones for fuel because the glucose from carbs is already available.

In addition, taking ketone supplements decreases free fatty acids, which means less fat is available for burning. In other words, your body uses up less of its own fat. This is because rapidly elevating your ketone levels by taking ketone supplements triggers a safety mechanism that is a natural defence mechanism designed to protect you from unnaturally high levels of ketones, which can result in a dangerous condition called ketoacidosis.

Therefore, keto pills are unlikely to speed up fat adaptation.
