The ketogenic diet has been a popular topic in recent years, with many people adopting it for weight loss and health benefits. One concern that has arisen is the potential link between the ketogenic diet and gallstones. Gallstones are a common condition, especially in adults in the US, and can lead to gallbladder attacks and even surgery in some cases. While some believe that the high-fat content of the ketogenic diet may contribute to gallstone formation, others argue that it is the reduction of carbohydrates and the promotion of bile flow that helps prevent gallstones. So, does the ketogenic diet cause gallstones, or does it help prevent them?

Ketogenic diets are high in fat and protein, and low in carbohydrates
The ketogenic diet is a low-carbohydrate, high-fat diet that has been used to treat specific medical conditions since the 1920s. It is distinctive for its exceptionally high-fat content, typically comprising 70% to 80% fat, with moderate protein intake making up the remaining 20-30%. The diet prescribes high levels of fat and protein with minimal carbohydrates to provide adequate nutrients while maintaining a state of ketosis. Ketosis is a metabolic state in which the body uses fat for fuel instead of carbohydrates.
The ketogenic diet has been shown to produce beneficial metabolic changes in the short term, including improved insulin resistance, lower blood pressure, and reduced cholesterol and triglycerides. It has been used to treat epilepsy in children, and there is growing interest in its potential to help with type 2 diabetes. The diet is also being studied for its effects on other progressive neurological disorders like Parkinson's disease.
However, the ketogenic diet may not be suitable for everyone. It has been linked to an increased risk of gallstones, especially in those who already have gallbladder disease. The gallbladder stores bile, which is used to digest the fat you eat. When consuming a low-fat diet, less bile is needed for digestion, and more can stagnate in the gallbladder, potentially forming gallstones. On the other hand, consuming a high-fat diet can lead to cholesterol buildup in the liver, which can also contribute to gallstone development.
The standard ketogenic diet (SKD) is the most researched and recommended version of the diet. It typically contains 70% fat, 20% protein, and only 10% carbohydrates. The protein amount is kept moderate because eating too much protein can prevent ketosis, as amino acids in protein can be converted to glucose.

The ketogenic diet can slow bile production, leading to gallstones
The ketogenic diet is a low-carbohydrate, high-fat, and high-protein diet that puts the body into a state of ""ketosis", where body energy comes from burning fat stores instead of sugar. While the ketogenic diet can be beneficial for weight loss and managing certain health conditions, there are some concerns about its impact on the gallbladder and bile production.
The gallbladder is a small organ located under the liver on the right side of the abdomen. It stores bile, a fluid produced in the liver, which is released into the small intestine to aid in the digestion of fats. Bile is crucial for breaking down fats and extracting fat-soluble vitamins from food. However, when bile remains in the gallbladder for prolonged periods without being released, it can become stagnant and lead to the formation of gallstones.
The ketogenic diet's high-fat content ensures sufficient fat intake to prevent the complete drying up of bile. However, frequent fasting, which is often incorporated into the ketogenic diet, can slow down bile production and usage. This reduction in bile flow can result in bile stagnation in the gallbladder. Over time, this stagnant bile can turn into sludge and eventually harden into gallstones.
Additionally, rapid weight loss, which can occur with the ketogenic diet, is another factor that can contribute to bile stagnation and gallstone formation. During rapid weight loss, the gallbladder may not be able to secrete bile fast enough, leading to a buildup of bile that can turn into gallstones. Therefore, while the ketogenic diet's high-fat content may provide some protection against bile drying, the combination of frequent fasting and rapid weight loss can still lead to slowed bile production and gallstone formation.
However, it is important to note that the relationship between the ketogenic diet and gallstones is complex. Some sources suggest that the ketogenic diet may help flush the gallbladder of stagnant bile and prevent gallstones. Additionally, certain dietary factors, such as excessive sugar and grain consumption, are associated with increased gallstone risk, and these are typically avoided on a ketogenic diet. Therefore, while the ketogenic diet can slow bile production through frequent fasting, it may also have indirect benefits for gallbladder health by eliminating these dietary risk factors.

Low-fat diets can increase the risk of gallstones
The gallbladder stores bile, a yellow-green fluid manufactured in the liver, which is used to digest the fat you eat. When a low amount of fat is consumed over a long period, bile in the gallbladder can stagnate and become supersaturated with cholesterol, which then hardens into stones.
A low-fat diet may be beneficial for those suffering from steatorrhoea (pale, yellow, orange, or oily stools that may float or be foul-smelling). However, a completely fat-free diet is not recommended, as a small amount of fat is needed by the body. A low-fat diet may also be beneficial if you are already suffering from gallstones, as it can prevent episodes of pain from gallstones or make them less frequent.
However, the current medical wisdom of cutting out fat from your diet altogether may cause the formation of more gallstones in the long run. This is because when less fat is consumed, less bile is needed to digest food, and more bile stays in the gallbladder. This can lead to the formation of gallstones. Studies have shown that people who eat low-fat diets are at an increased risk of developing gallstones. In one study, 6 out of 11 people eating an extremely low-fat diet developed new gallstones, while nobody in the group eating a diet slightly higher in fat did. Another study of 51 obese people found that 4 participants developed new gallstones after one month of an extremely low-fat, low-calorie diet, and 13 people had new gallstones after two months.
Furthermore, rapid weight loss (greater than 2 lbs or 1 kg per week) may increase the chance of gallstone formation. This is because weight loss, especially rapid weight loss with a lack of fat intake, allows bile to stagnate in the gallbladder and form stones.

Rapid weight loss is a risk factor for gallstones
Gallstones are hardened deposits of digestive fluid that can form in the gallbladder. The gallbladder is a small, pear-shaped organ located on the right side of the abdomen, beneath the liver. It stores bile, a digestive fluid produced in the liver, which is released into the small intestine to aid in the digestion of fat.
While obesity is a well-known risk factor for gallstones, rapid weight loss can also increase the likelihood of developing this condition. When an individual loses weight rapidly, the body metabolizes fat quickly, leading to an increase in cholesterol secretion into the bile. This disruption in the balance of cholesterol and bile acids can cause the bile to stagnate and form stone-like deposits.
The ketogenic diet, which involves a strict elimination of carbohydrates, can promote rapid weight loss. This type of diet can affect the gallbladder by slowing down bile production and usage, leading to bile stagnation and the potential formation of gallstones. Additionally, the ketogenic diet's high-fat content may contribute to cholesterol build-up in the liver, further increasing the risk of gallstone development.
To prevent gallstones, it is recommended to avoid rapid weight loss and aim for a steady, gradual approach. Modest weight loss of 1/2 to 2 pounds per week is considered ideal, as it lowers the risk of gallstones and encourages sustainable habits. It is also important to maintain a healthy weight, as both obesity and being overweight increase the chances of developing gallstones.
While dietary choices may vary, it is generally recommended to include healthy fats and complex carbohydrates in the diet, while limiting simple carbohydrate intake. This approach promotes gallbladder health and helps prevent the formation of gallstones.

The ketogenic diet can help prevent gallstones by flushing out the gallbladder
Gallstones are a common condition in US adults, with surgery to remove the gallbladder being one of the most frequently performed operations in the country. The gallbladder stores bile, a substance that is used to digest the fat that we eat. When an individual consumes a low amount of fat for a sustained period, the bile in the gallbladder can stagnate and turn into stones. This can lead to a gallstone attack, which is characterised by pain in the top right part of the stomach.
Furthermore, the ketogenic diet eliminates simple carbohydrates, which have been associated with gallstone formation. Simple carbohydrates contribute to magnesium deficiency, leading to the calcification of cells that make up gallstones. By removing these carbohydrates, the diet may promote gallbladder health and reduce the likelihood of stone formation.
However, it is important to note that excessive protein consumption on the ketogenic diet may lead to gallstone formation. Additionally, rapid weight loss, which can occur on this diet, can increase the risk of gallstones. Therefore, while the ketogenic diet may help prevent gallstones by flushing out the gallbladder, it should be approached with caution and in consultation with a healthcare professional.
