The ketogenic diet, commonly known as the keto diet, is a dietary approach characterized by low carbohydrate and high-fat intake. It aims to induce a metabolic state called ketosis in the body. Keto gummies are marketed as supplements that support a ketogenic diet, aiding in weight loss, boosting energy and metabolism, and providing other potential benefits.
Understanding Keto Gummies
Keto gummies are supplements designed to resemble regular chewable vitamins but offer a different purported health benefit. They are marketed as a way to help boost ketone levels in the blood. However, it's important to note that dietary supplements are not approved for safety or efficacy by the Food and Drug Administration (FDA), and the ingredients and their amounts may vary.
How the Keto Diet Works
In general, the body relies on carbohydrates for fuel. However, when carbohydrate intake is insufficient, the body enters a state known as "nutritional ketosis." In this state, the body starts to break down fat for energy instead. According to Katie Schwartz, a registered dietitian based in Asheville, North Carolina, it typically takes a few days of strict carbohydrate restriction to enter this state. Once the body enters ketosis, it begins producing ketones, which are then used for fuel.
Ingredients in Keto Gummies
Keto gummies often contain ingredients such as:
- Medium-chain triglyceride (MCT) oil: MCT oil may provide a quick source of energy.
- Exogenous ketones: Exogenous ketones are produced outside of the body and consumed orally, as opposed to endogenous ketones that are produced inside the body. Exogenous ketones include ketone salts and ketone esters, which have different chemical structures and potencies, with esters considered more potent.
The Claimed Benefits of Keto Gummies
Keto gummies are often marketed with claims of various benefits, including:

- Weight loss: Keto gummies are purported to help with weight loss by promoting ketosis and fat burning.
- Increased energy: MCT oil and exogenous ketones are claimed to provide a quick source of energy.
- Boosted metabolism: Some keto gummies claim to boost metabolism, aiding in weight management.
Do Keto Gummies Actually Work?
Research is sparse when it comes to determining whether keto gummies and supplements support losing weight. According to Schwartz, there is no credible evidence that keto gummies can reliably initiate or maintain ketosis. These products are not evidence-based and often rely on misleading marketing.
Safety Considerations
Being in ketosis is generally considered safe; however, certain individuals should exercise caution when considering keto gummies. People with underlying health conditions like kidney disease or diabetes, people who are pregnant or nursing, children, or anyone on medications affecting blood sugar shouldn’t use keto gummies, notes Rancourt.
The Role of Ketones
When the body is in a state of ketosis, it produces ketones, which serve as an alternative fuel source when glucose from carbohydrates is limited. There are three main types of ketones:
- Acetoacetate (AcAc): This is the first ketone body produced during ketosis.
- Beta-hydroxybutyrate (BHB): This is the most abundant ketone body in the blood during ketosis.
- Acetone: This is a less abundant ketone body that is produced as a byproduct of acetoacetate metabolism.
Exogenous ketones, found in keto gummies, are designed to mimic the effects of endogenous ketones produced by the body during ketosis. However, the efficacy and safety of exogenous ketones are still under investigation.
Potential Benefits of Ketosis
While the research on keto gummies specifically is limited, the ketogenic diet and ketosis, in general, have been studied for various potential benefits, including:

- Weight loss: The keto diet can be effective for weight loss due to its ability to promote fat burning and reduce appetite.
- Improved blood sugar control: The keto diet can help improve blood sugar control in people with type 2 diabetes.
- Reduced seizure frequency: The keto diet has been used to reduce seizure frequency in children with epilepsy.
- Improved cholesterol levels: The keto diet may improve cholesterol levels by increasing HDL (good) cholesterol and lowering triglycerides.
Potential Risks and Side Effects of Ketosis
While ketosis is generally considered safe for most people, there are potential risks and side effects to be aware of, including:
- Keto flu: This is a collection of flu-like symptoms that can occur when first starting the keto diet, including fatigue, headache, nausea, and constipation.
- Nutrient deficiencies: The keto diet can be restrictive, and it may be difficult to get all the necessary nutrients.
- Kidney stones: The keto diet can increase the risk of kidney stones in some people.
- Constipation: The keto diet can lead to constipation due to the low intake of fiber.
The Importance of a Balanced Keto Diet
If following a ketogenic diet, it's crucial to ensure it's well-balanced and provides all the necessary nutrients. This involves:
- Eating plenty of non-starchy vegetables: These provide essential vitamins, minerals, and fiber.
- Choosing healthy fats: Opt for sources like avocados, nuts, seeds, and olive oil.
- Including adequate protein: Protein is essential for maintaining muscle mass and overall health.
- Staying hydrated: Drink plenty of water to prevent dehydration and constipation.
Consulting with a Healthcare Professional
Before starting any new diet or supplement regimen, including the keto diet or keto gummies, it's essential to consult with a healthcare professional. This is especially important for individuals with underlying health conditions, pregnant or nursing women, and those taking medications.
