Constipation on a Carnivore Diet: Causes and How to Fix It

Constipation is one of the most common concerns when people start a carnivore diet. However, it’s important to understand that digestion changes significantly when you remove fibre.

On a carnivore diet, the body absorbs most of the food you eat. As a result, there is less waste, which means stools are often smaller and less frequent. This is normal and should not automatically be mistaken for constipation.

True constipation is characterized by hard, dry stools, straining, discomfort, or a feeling of incomplete evacuation.

What causes constipation on Carnivore?

1.  Not eating enough fat

One of the most common causes is not eating enough fat. Fat plays a key role in digestion by stimulating bile flow and helping move food through the digestive tract. When meals are too lean, digestion can slow down, leading to constipation.

2. Electrolytes and hydration

Another important factor is hydration and electrolytes. On a carnivore diet, the body tends to lose more sodium and water. If electrolytes are too low, the colon can absorb too much water from stool, making it dry and difficult to pass.

3. Stress

Stress also plays a major role. When stress levels are high, the body produces more cortisol, which shifts the body into a “survival mode.” In this state, digestion slows down, and bowel movements can become less regular.

4. Body need time to adapt

In addition, digestion itself may need time to adapt. During the first few weeks on carnivore, the gut is adjusting to a new way of eating, including changes in gut bacteria and the absence of fibre. Temporary constipation during this phase is not uncommon.

5. Bad Habits

Finally, eating habits and nervous system state matter more than most people realize. Eating quickly, not chewing properly, or eating while stressed can all reduce digestive efficiency and slow gut movement.

How to fix constipation on Carnivore

1. Increase fat intake

   The first step is to increase fat intake. Choosing fattier cuts of meat or adding butter or tallow can significantly improve digestion and bowel movement.

2. Increase electrolytes

   It’s also important to maintain proper electrolyte balance, especially sodium. Salting food adequately and staying hydrated can help prevent stools from becoming too dry.

3. Reducing stress

   Reducing stress around meals can make a big difference.

4. Eating slowly, chewing thoroughly, and allowing the body to relax supports proper digestive function.

5. Light movement, such as walking, can also help stimulate gut motility and improve regularity.

6. Add in some vitamin C

7. Add in some more Magnesium

   
   

⚠️ What about fibre?

Constipation is often blamed on a lack of fibre, but in many cases, the issue is not the absence of fiber—it is how the digestive system is functioning.

Fibre mainly adds bulk to stool, but it does not address underlying issues like low fat intake, dehydration, or stress.

Constipation on a carnivore diet is usually not caused by removing fibre. It is more often related to fat intake, hydration, stress, or the body adapting to a new way of eating.

Once these factors are addressed, digestion typically becomes more efficient and comfortable.
