The ketogenic diet, or keto diet, has gained immense popularity as a low-carbohydrate, high-fat approach to shifting the body into a metabolic state known as ketosis. In this state, the body primarily burns fat for fuel instead of carbohydrates. Keto gummies have emerged as a popular supplement marketed to support this ketogenic diet, promising benefits such as weight loss, increased energy, and improved metabolism. However, it's crucial to examine what these gummies contain and whether they live up to their claims.
What are Keto Gummies?
Keto gummies are supplements designed to resemble ordinary chewable vitamins but with the added benefit of potentially boosting ketone levels in the blood. According to Katie Schwartz, a registered dietitian, they are marketed as a way to enhance ketone levels. When carbohydrate intake is severely restricted, the body enters nutritional ketosis and begins breaking down fat for energy. This process results in the production of ketones, which the body then utilizes as fuel. Keto gummies aim to supplement this process.
Ingredients in Keto Gummies
Most keto gummies contain medium-chain triglycerides (MCTs), a type of saturated fat that provides the body with energy. Additionally, they include exogenous ketones, which are ketones sourced outside the body. These exogenous ketones come in two main forms: ketone salts and ketone esters. Ketone esters are generally considered more potent than ketone salts. Some keto gummies may also contain gelatin or natural sweeteners like Stevia to enhance their taste without adding extra sugars that could disrupt ketosis.
Do Keto Gummies Work? Examining the Evidence
The primary question surrounding keto gummies is whether they actually deliver on their promises. According to Schwartz, "There’s no credible evidence that keto gummies can reliably initiate or maintain ketosis." Research on the effectiveness of keto gummies and supplements in supporting weight loss is sparse. Many experts argue that these products are not evidence-based and often rely on misleading marketing tactics.
Beth Czerwony, a registered dietitian, clarifies that keto gummies do not initiate ketosis. "Keto gummies may help the process of ketosis continue, but you need to be in ketosis first," she explains. Therefore, these gummies are intended to supplement an existing keto diet rather than replace it.

Potential Benefits
Despite the limited research, some potential benefits have been associated with keto gummies:
- Increased weight loss: Some proponents suggest that keto gummies can aid in weight loss by boosting ketone levels and promoting fat burning.
- Improved athletic performance: MCTs in keto gummies may provide a quick source of energy, potentially enhancing athletic performance.
- Decreased appetite: Keto gummies may help reduce appetite, making it easier to adhere to a calorie-restricted diet.
However, it's important to reiterate that these benefits are largely based on anecdotal evidence and lack robust scientific backing. One study suggests that supplements may increase ketone levels too much, potentially hindering the liver's natural ketone production and making it harder to stay in ketosis.
Potential Risks
Before incorporating keto gummies into your diet, it's essential to be aware of the potential risks:
- Nausea and vomiting: Some individuals may experience nausea or vomiting as a result of taking keto gummies.
- Gastrointestinal issues: Diarrhea and other gastrointestinal issues are potential side effects, especially if the gummies contain sorbitol, a known laxative.
- Low blood sugar: Keto gummies can potentially lower blood sugar levels, leading to hypoglycemic responses, particularly in individuals with Type 2 diabetes or those taking medications that affect blood sugar.
- Dehydration: The keto diet and keto supplements can sometimes lead to dehydration.
Who Should Avoid Keto Gummies?
Certain individuals should exercise caution or avoid keto gummies altogether:
- People with underlying health conditions: Those with kidney disease or diabetes should consult their healthcare provider before using keto gummies.
- Pregnant or nursing women: The safety of keto gummies during pregnancy and breastfeeding has not been established.
- Children: Keto gummies are not recommended for children.
- Individuals on medications affecting blood sugar: Keto gummies can interact with medications that regulate blood sugar levels.
Making an Informed Decision
If you're considering trying keto gummies, it's crucial to first evaluate your current diet and lifestyle. Czerwony suggests asking yourself why your body isn't staying in ketosis. Are you consuming too many carbohydrates? Are you feeling bored or hungry on the diet? Addressing these issues through dietary adjustments may be a healthier and more sustainable approach than relying solely on supplements.

If you decide to try keto gummies, Czerwony recommends starting with a small batch to assess your tolerance and ensure you like them. It's also essential to consult with a healthcare provider before adding keto gummies to your regimen, especially if you have any underlying health conditions or are taking medications.
