The carnivore diet, characterized by the consumption of primarily animal products, has gained popularity for its potential benefits in weight loss, inflammation reduction, and digestive health improvement. As the body adapts to this unique dietary approach, changes in stool color and consistency are common. This article delves into the intricacies of stool changes on the carnivore diet, offering insights into what is considered normal, potential causes for concern, and practical tips for maintaining optimal digestive health.
Introduction to the Carnivore Diet and its Impact on Digestion
The carnivore diet focuses on meat and animal products, such as fish, eggs, and some dairy, while largely excluding plant-based foods like vegetables and grains. Many individuals adopt this diet for its potential to promote weight loss, reduce inflammation, improve digestion, and increase energy levels. Studies suggest that the carnivore diet can indeed have positive health effects, including weight loss and increased energy. Moreover, it can provide all the essential nutrients required, even without the inclusion of plant-based foods.
The carnivore diet can influence digestive health. A 2021 study indicated that a majority of participants experienced fewer digestive problems and greater satisfaction with their health, highlighting the diet's potential positive impact on stomach health. Contrary to the belief that avoiding plant-based foods and fiber leads to digestive issues, a 2012 study suggested that fiber may not be as effective as commonly perceived.
What to Expect: Normal Stool Characteristics on the Carnivore Diet
When transitioning to a carnivore diet, it's normal to experience changes in bowel movements as the body adjusts to the new eating habits. Since this diet is largely devoid of fiber, bowel movements may become less frequent. Some individuals may have only one bowel movement per day or every few days, while others may experience even less frequent movements without any discomfort.
Individuals who consume only meat tend to produce less waste, which may result in less frequent bowel movements. This is not necessarily a sign of constipation. Meat takes longer to digest than plant-based foods, leading to less frequent but regular and predictable bowel movements.

Normal stool on a carnivore diet is generally firm and well-formed, often appearing cylindrical or sausage-shaped. The texture can be softer and easier to pass with adequate hydration and good overall digestive health. The firmness of the stool is also related to the lower fiber intake.
The Bristol Stool Chart can be a helpful tool for assessing stool consistency on the carnivore diet. Types 3 and 4 on the chart are generally considered normal.
Decoding Stool Color Changes on the Carnivore Diet
Stool color is primarily influenced by bile, a fluid that aids in fat digestion. Bile levels naturally fluctuate over time, leading to variations in stool color from day to day and from person to person.
While shades of brown and even green can be normal, it's crucial to be vigilant. The absence of colorful plant foods in the carnivore diet may lead to less variation in stool color. Bright red or black in the stool could indicate the presence of blood, warranting immediate medical attention. Green stools may occur if food is processed too quickly, such as during dietary adjustments or in cases of diarrhea, preventing bile from fully breaking down.
Medications and supplements can also influence stool color. For example, iron supplements and certain antibiotics can alter stool color to dark brown, black, yellow, or green, regardless of diet.

It's essential to pay attention to any significant or persistent changes in stool color and consult a healthcare professional if necessary.
Addressing Constipation on the Carnivore Diet
Constipation can occur on the carnivore diet for several reasons. As the body adapts to digesting more proteins and fats, it can be challenging and may lead to constipation. A significant loss of water can occur as the body utilizes stored glycogen, and this decrease in hydration can affect bowel movements. Therefore, it's crucial to drink enough water to prevent dehydration and constipation.
The shift in diet also alters the gut bacteria. Moving from a high-carb to a low-carb diet changes the types of bacteria in the gut, which can slow down the movement of food through the intestines. Imbalances in essential minerals like magnesium, calcium, potassium, and sodium, which are vital for intestinal muscle function, can also contribute to constipation.
Certain foods common in the carnivore diet, particularly processed meats and dairy, can induce constipation, especially in individuals with intolerances or allergies.
Managing Diarrhea on the Carnivore Diet
Diarrhea can also occur in some individuals when starting the carnivore diet. Switching from a diet rich in carbohydrates to one primarily composed of meat can cause changes in the gut bacteria, potentially upsetting the stomach and leading to diarrhea.

An increased intake of dietary fats is another contributing factor. The carnivore diet involves a substantial increase in fat consumption and a decrease in carbohydrates. This shift requires the body to adapt to processing fats differently, relying on digestive enzymes to break down fats more efficiently. The gallbladder plays a crucial role in fat digestion by storing and releasing bile, which helps break down fats in the small intestine. This adjustment can initially result in diarrhea as the body learns to process the higher fat content efficiently.
Inadequate intake of certain vitamins, like D and A, or minerals like zinc, can also lead to diarrhea. Consuming beef liver and spending time in the sun can help increase vitamin D levels.
Consuming too much protein, especially if not accustomed to it, can also cause diarrhea. The body has a limit on how many amino acids it can digest, which depends on age and digestive conditions. Exceeding this limit leads to the production of ammonia, which can result in diarrhea as the body tries to excrete it.
Determining Normal Bowel Movement Frequency
Bowel movement frequency on the carnivore diet can vary from person to person. A healthy range is considered to be anywhere from three times a week to three times a day. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) states that having at least three bowel movements per week is healthy.
When to Seek Medical Advice
It's important to consult a healthcare professional if you experience any of the following:
- Significant changes in the texture, volume, or appearance of stools, such as becoming too narrow, watery, or significantly different in color.
- Constipation or diarrhea that lasts more than two weeks, or if these conditions are accompanied by severe symptoms like stomach pain or signs of dehydration.
- Blood or mucus in the feces.
- Stools that are deep red, maroon, black, or tarry, especially with a strong odor.
- Symptoms like constipation with nausea, dark urine, a fever, or yellowing of the skin.
These symptoms could indicate a serious underlying issue and require prompt medical attention.
Practical Tips for Maintaining Digestive Health on the Carnivore Diet
- Increase Dietary Fat: Adjust the macronutrient balance by increasing the intake of fat. Consume fatty cuts of meat and animal fats like tallow, butter, and suet.
- Stay Hydrated and Balance Electrolytes: Drink enough water to prevent dehydration. Add electrolytes, such as sodium, potassium, and magnesium, to support nerve and muscle function in the gastrointestinal tract.
- Adjust Protein Sources: If you eat more lean protein, then you should eat fattier animal-based sources to keep your macros balanced. Avoid eating very lean meats like chicken breast all the time. Include nutrient-dense foods such as organ meats and eggs to get the necessary macros and balance your macronutrient intake.
- Use Digestive Aids and Supplements: After consulting a healthcare professional, consider using natural laxatives such as magnesium citrate on a short-term basis to stimulate bowel movements. Probiotics and digestive enzymes can also help improve gut motility and microbial balance.
- Engage in Regular Physical Activity: Regular physical activity has been shown to improve gut motility.
- Transition Gradually and Monitor Changes: Transition gradually into the carnivore diet, especially if you are used to high-carbohydrate diets. Keep a food and symptom journal to monitor what works best for your body as it is adapting to the low-carb eating style.
- Eat Mindfully: Chew food thoroughly and eat slowly to help your digestion and reduce the load on your gastrointestinal system. Avoid overeating in a single meal because it can cause bloating and slow motility.
- Choose the Right Foods: Select foods that support digestive efficiency while avoiding those that may disrupt gut function. Fatty foods are beneficial because they help bile secretion and facilitate intestinal transit. On the contrary, foods that are too lean or lack fats can worsen constipation.
