The ketogenic diet, characterized by high fat and very low carbohydrate intake, has gained popularity for its potential benefits, including weight loss, improved blood sugar control, and reduced seizures in specific medical conditions. As individuals seek easier ways to achieve ketosis, keto diet pills have emerged as a popular supplement. This article explores the science behind keto diet pills, their potential benefits and risks, and what to consider before using them.
What are Keto Diet Pills?
Keto diet pills, often marketed as "keto pills," are supplements that claim to boost ketosis. Ketosis is a metabolic state where the body burns fat instead of carbohydrates for energy. This process occurs when carbohydrate intake is significantly reduced, typically to 20-50 grams per day, forcing the body to break down fat into ketone bodies, which are then used for fuel.
These pills often contain exogenous ketones, which are ketones derived from an external source. The intention is to elevate ketone levels in the body, potentially mimicking or enhancing the effects of a ketogenic diet. Medium-chain triglycerides (MCTs) are also commonly found in keto gummies, providing the body with a source of energy. Some keto gummies may also contain gelatin or natural sweeteners like Stevia.
How Do Keto Diet Pills Work?
The primary goal of keto diet pills is to elevate ketone levels in the bloodstream, thus supporting the state of ketosis. By providing exogenous ketones, these pills aim to help users maintain ketosis, especially when dietary adherence is challenging. However, it's crucial to understand that keto pills do not induce ketosis on their own. They are designed to supplement an existing ketogenic diet.
Registered dietitian Beth Czerwony, RD, LD, explains that keto gummies may help the process of ketosis continue, but you need to be in ketosis first.

Potential Benefits of Keto Diet Pills
While research on keto diet pills is limited, some potential benefits have been suggested:
- Increased Weight Loss: Some studies suggest that ketogenic diets, in general, can lead to weight loss. A meta-analysis of randomized controlled trials indicated that very-low-carbohydrate ketogenic diets produced a slightly greater reduction in weight compared to low-fat diets over one year. However, it's important to note that this benefit is associated with the diet itself, not necessarily the pills.
- Improved Athletic Performance: Some proponents claim that keto pills can improve athletic performance by providing an alternative fuel source (ketones) for muscles. However, more research is needed to substantiate these claims.
- Decreased Appetite: Ketogenic diets have been shown to reduce appetite. A systematic review of short-term intervention trials found that overweight and obese individuals on ketogenic diets reported less hunger and a reduced desire to eat compared to baseline measures. It's theorized that changes in appetite hormones, ketone bodies, and increased fat and protein intakes contribute to this effect.
- Improved Blood Sugar Control: Following a ketogenic diet seems to improve blood sugar control in people with type 2 diabetes.
Potential Risks and Side Effects of Keto Diet Pills
Before considering keto diet pills, it's essential to be aware of the potential risks and side effects:
- Gastrointestinal Issues: Some keto pills, especially gummies, may contain sorbitol, a known laxative, which can lead to diarrhea and other gastrointestinal problems.
- Nausea and Vomiting: Nausea and vomiting are potential side effects of keto supplements.
- Low Blood Sugar: The keto diet, combined with keto supplements, can potentially lower blood sugar levels, leading to hypoglycemic responses.
- Dehydration: The keto diet can have a dehydrating effect on the body.
- Nutrient Deficiencies: Eliminating several food groups can lead to potential nutrient deficiencies if a variety of recommended foods on the ketogenic diet are not included.
- Diabetic Ketoacidosis (DKA): Following a very-low carbohydrate ketogenic diet might increase the risk for diabetic ketoacidosis (DKA), a serious complication of diabetes.
Important Considerations Before Using Keto Diet Pills
Before incorporating keto diet pills into your regimen, consider the following:
- Consult a Healthcare Provider: It's crucial to consult with a healthcare provider before starting any new supplement, especially if you have underlying health conditions like diabetes, high blood pressure, or kidney issues.
- Dietary Adjustments: Instead of relying solely on keto pills, focus on making necessary tweaks to your keto diet to ensure you're getting enough calories and fiber.
- Research and Understand Risks: Conduct thorough research to understand the potential risks and benefits of keto pills, and recognize that there's no conclusive research to support their effectiveness.
- FDA Regulation: Be aware that dietary supplements, including keto pills, are not regulated by the Food and Drug Administration (FDA) and may not do what they claim.
- Medication Interactions: The ketogenic diet might lower blood sugar levels. Following the ketogenic diet while also taking diabetes medications might cause blood sugar to drop too low.
Keto Diet Pills and Scams
It's essential to be cautious of scams associated with keto diet pills. The Federal Trade Commission (FTC) has warned against companies making unsubstantiated weight-loss claims and charging consumers exorbitant monthly fees. AARP's Fraud Watch Network has also reported an increase in keto pill scams, where fraudsters promise rapid weight loss but fail to deliver.
The Ketogenic Diet: A Deeper Dive
To fully understand the context of keto diet pills, it's helpful to delve deeper into the ketogenic diet itself. The ketogenic diet is a low-carbohydrate, fat-rich eating plan that has been used for centuries to treat specific medical conditions.

Historical Context
In the 19th century, the ketogenic diet was commonly used to help control diabetes. In 1920, it was introduced as an effective treatment for epilepsy in children in whom medication was ineffective.
How it Works
The premise of the ketogenic diet for weight loss is that if you deprive the body of glucose-the main source of energy for all cells in the body-an alternative fuel called ketones is produced from stored fat. The brain demands the most glucose in a steady supply, about 120 grams daily, because it cannot store glucose. During fasting, or when very little carbohydrate is eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the body begins to use fat as its primary fuel. The liver produces ketone bodies from fat, which can be used in the absence of glucose. When ketone bodies accumulate in the blood, this is called ketosis.
Macronutrient Ratios
There is not one “standard” ketogenic diet with a specific ratio of macronutrients (carbohydrates, protein, fat). The ketogenic diet typically reduces total carbohydrate intake to less than 50 grams a day-less than the amount found in a medium plain bagel-and can be as low as 20 grams a day. Generally, popular ketogenic resources suggest an average of 70-80% fat from total daily calories, 5-10% carbohydrate, and 10-20% protein.
Food Choices
Many versions of ketogenic diets exist, but all ban carb-rich foods. Some of these foods may be obvious: starches from both refined and whole grains like breads, cereals, pasta, rice, and cookies; potatoes, corn, and other starchy vegetables; and fruit juices. Some that may not be so obvious are beans, legumes, and most fruits. Most ketogenic plans allow foods high in saturated fat, such as fatty cuts of meat, processed meats, lard, and butter, as well as sources of unsaturated fats, such as nuts, seeds, avocados, plant oils, and oily fish.
Potential Benefits of the Ketogenic Diet
- Weight Loss: Following a ketogenic diet that limits carbohydrate intake to less than 50 grams daily can reduce body weight by 10% to 30% in 1 year.
- Seizure Disorder (Epilepsy): A strict ketogenic diet that is high in fat and very low in carbohydrates can reduce seizures in some people with hard-to-treat epilepsy.
- Diabetes: Following a ketogenic diet seems to improve blood sugar control in people with type 2 diabetes.
Potential Risks of the Ketogenic Diet
- Common Side Effects: The most common side effects include constipation, fatigue, dizziness, headache, weakness, nausea, diarrhea, and stomach pain.
- Long-Term Safety: The long-term safety of the ketogenic diet in adults is unknown. It is important to ensure any diet remains balanced and contains nutrient-rich foods.
- Special Precautions: The ketogenic diet is likely safe for most adults when used for up to 1 year. It is important to ensure any diet remains balanced and contains nutrient-rich foods.
- Liver Disease: The ketogenic diet might cause liver injury and may worsen symptoms of liver disease.
- Kidney Disease: The ketogenic diet may worsen kidney disease and has been linked with kidney stone development.
The Quest for a "Keto Pill"
Researchers have been exploring the mechanisms of the ketogenic diet to potentially replicate its effects in a pill form. However, it's unlikely that a single "magic bullet" can completely mirror the anticonvulsant and potential neuroprotective effects of the KD.
