The ketogenic diet, or keto diet, has gained immense popularity for its potential benefits in weight loss and metabolic health. However, its high-fat content raises concerns about its impact on the gallbladder, an organ crucial for fat digestion. This article explores the relationship between the keto diet and gallbladder health, addressing potential problems and offering strategies to support optimal gallbladder function.
The Gallbladder's Role in Digestion
Although its importance is often overlooked, the gallbladder plays a vital role in dietary fat emulsification, nutrient absorption, and digestive health. The gallbladder is a small, pear-shaped organ located beneath the liver in the right quadrant of the abdomen. The primary function of the gallbladder is to store and concentrate bile, a digestive fluid produced by liver cells. When we eat a meal, some bile flows directly from the liver to the digestive system, but the gallbladder also pitches in to help. The gallbladder releases concentrated bile that breaks down fat via emulsification. Bile aids in the digestive process by breaking up fats and helping the small intestine absorb them as well as fat-soluble vitamins. It helps carry waste out of the body, and through secretion, is also a major channel for passing cholesterol out of the body. While being stored there, the bile becomes five times more concentrated.
Potential Gallbladder Issues
The gallbladder can cause some big problems when it acts up. For reasons that are unclear, sometimes the substances in bile crystallize in the gallbladder forming hard deposits known as gallstones. Though usually harmless, these stones can be painful and can cause nausea and inflammation. The gallbladder can become infected, usually due to complications with a gallstone. It can also be affected by cancer and can contribute to pancreatitis.
Sludge formation and gallstones obstructing the bile ducts may also lead to biliary colic, widely referred to as gallbladder attacks, resulting in sudden, sharp pain, nausea, or vomiting. Over time, gallstones can accumulate and cause an inflamed gallbladder, a condition known as acute cholecystitis. However, symptoms of gallbladder issues can vary widely, and many people remain unaware until years after gallstones have formed. Gallbladder sludge, or biliary sludge, develops due to overly concentrated bile, cholesterol, and waste products that can stagnate and cause symptoms such as abdominal pain and nausea, especially after eating.
Causes of a Sluggish Gallbladder
A gallbladder can become sluggish due to a high-carb diet, hormonal changes, rapid weight loss, dehydration, stress, and lack of adequate intake of healthy fats. Because the presence of dietary fats triggers the gallbladder to contract and release bile into the small intestine, low-fat diets are the most common cause of sluggish gallbladders. Low-fat foods reduce bile demand, which can lead to bile sludge, gallbladder inflammation, and impaired digestive function overall. High carbohydrate intake can also contribute to poor bile flow. Conditions that cause chronic inflammation in the gut or liver, including irritable bowel disease (IBD), cirrhosis, and diabetes, can also increase the risk of biliary sludge. Research published in the World Journal of Gastroenterology found that approximately one-third of patients with liver cirrhosis develop pigment or cholesterol gallstones resulting from hepatic metabolic changes.

Keto Diet and Gallbladder Health: A Complex Relationship
The keto diet, characterized by high fat, moderate protein, and very low carbohydrate intake, can impact gallbladder function in several ways.
Potential Benefits
If you haven’t had your gallbladder removed but are concerned about developing gallbladder issues, following a keto diet may actually be a healthy way to avoid gallstones. In one study, researchers followed two groups of obese patients who were on a low-calorie diet. After six months, 50% of the low fat group had developed gallstones. In the high fat group? The reasoning behind this is that when you regularly eat a diet high in fat, more bile is regularly produced to digest it. The result is that the bile ducts and gallbladder are consistently being flushed and refilled, giving less of a chance for stones to form and more of a chance for existing stones to be flushed out. Dr. “If you don’t eat fat because you follow the low fat dogma, your gallbladder doesn’t empty,” Dr. Mason said. “You’ve got that fluid sitting there, and then it turns to sludge. When you suddenly cheat on your low fat diet and splurge on a high fat meal, that giant blockage suddenly begins to try to move out of your gallbladder, which is very painful.
Stimulation of Bile Flow: Healthy fatty foods, such as oily fish, meat, eggs, butter, and coconut oil, promote bile flow and optimize digestion. This explains why a low-carb, high-fat Healthy Keto® diet can support metabolic health and gallbladder efficiency by significantly reducing carbohydrate and increasing fat consumption.
Reduced Risk of Sludge: High carb and sugar intake significantly increases the risk of biliary sludge, while saturated fats trigger the release of bile and help maintain its fluidity.
Potential Risks
Increased Bile Demand: The high fat content of the keto diet necessitates increased bile production and release. This can put a strain on the gallbladder, especially in individuals with pre-existing gallbladder conditions.

Gallstone Formation: Rapid weight loss, often associated with the keto diet, causes the liver to eliminate excess cholesterol, which can supersaturate bile and affect its composition. Restrictive diets may also cause the gallbladder to contract less frequently, causing bile to remain in the gallbladder to stagnate and thicken. A study published in the Archives of Internal Medicine found that prolonged calorie restriction predisposed subjects to develop gallstones and gallbladder sludge after eight weeks of dieting.
Supporting a Healthy Gallbladder on Keto
Various beneficial dietary and lifestyle changes can help support a healthy gallbladder by promoting normal bile consistency and flow.
Here are five natural steps you can take to optimize gallbladder function.
- Healthy Keto® and Intermittent Fasting: High carbohydrate intake is a primary cause of insulin resistance and poor gallbladder function. Excess insulin can increase cholesterol in bile, reduce stomach acidity, and slow gallbladder motility, all of which impair gallbladder emptying, causing bile to stagnate. Additionally, intermittent fasting, which involves time-restricted periods of eating and fasting, can promote normal bile concentration and improve metabolic markers linked to gallbladder sludge and gallstone disease.
- Include bitter vegetables like arugula, kale, and broccoli with your meals.
- Lose weight gradually: Losing weight gradually by adopting a nutritious diet combined with exercise allows the gallbladder to adjust to dietary changes and maintain healthy digestive function.
- Stay hydrated: Dehydration can contribute to the formation of gallbladder sludge, as bile acids, cholesterol, and other compounds become overly concentrated and stagnant without sufficient water to keep bile flowing freely. Staying hydrated by drinking plenty of fluids and replenishing electrolytes helps dilute bile acids and maintain bile fluidity.
Keto Diet Without a Gallbladder
Have you had your gallbladder removed? Wondering if it’s possible to follow the keto diet without a gallbladder? To cut to the chase, yes, it is possible to eat keto if you don’t have a gallbladder. Despite the gallbladder’s role in storage and digestion, it’s not an essential organ. Many people have it removed and live perfectly healthy lives without a gallbladder.
When you don’t have a gallbladder, you can still digest fats. Remember, some bile is released directly into the digestive system by the liver. As your body adapts to being without a gallbladder, less bile will be produced. Because the bile is now being released into the small intestine instead of stored between meals, it affects the speed at which food is processed. Because of this, some people will experience digestive issues like diarrhea following surgery. You can help mitigate digestive issues by eating smaller, more frequent meals, which will mean more available food to mix with the bile, and adding more fiber-rich foods to your diet, which can normalize bowel movements.

Tips for Following a Keto Diet After Gallbladder Removal
If you’ve had your gallbladder removed and want to start or resume a keto diet, it’s best to ease into it. Even if you were adhering to a keto diet before surgery, you might not be able to pick up where you left off right away. Directly following surgery, doctors advise patients avoid very high fat foods right after surgery, as these can contribute to digestive issues. Doctors recommend eating plenty of fiber to help regulate digestive functions and bowel movements. Without a gallbladder to store excess bile, bile will drip continuously from your liver into your digestive system. To help your body adjust to the change and absorb more of the excess bile, eat smaller meals more frequently. For instance, you might eat five or six light meals spaced out a few hours apart rather than one large meal at breakfast, lunch and dinner.
Supplements to Consider
- MCT Oil: Consider using MCT oil to supplement your dietary fat intake. Left Coast’s 100% Pure Coconut MCT Oil contains the foundational healthy fatty acids C8 and C10, which help increase energy, curb cravings and improve cognitive performance while boosting the fat intake you get from food alone. You can add MCT oil to your morning coffee, blend it into smoothies, drizzle it over salad or substitute it pretty much anywhere you’d use olive oil.
- Lipase: Next up is lipase, a pancreatic enzyme that acts as a catalyst in the digestion of fat.
- Ox Bile: Keto followers who have had their gallbladder removed may also benefit from supplementing naturally produced bile with ox bile, especially when eating high fat meals. Derived from oxen, ox bile mimics the effects of our own bile in the digestive process.
