Keto Os Max: Diarrhea Side Effect?

The keto diet is a popular eating plan that has been hailed as an effective way to lose weight. However, it has been linked to several gastrointestinal issues, including diarrhea. This is because the diet involves a significant increase in fat consumption and a decrease in carbohydrates, which can be challenging for the body to adjust to. In addition, artificial sweeteners and sugar alcohols, which are commonly consumed on the keto diet, can also cause digestive problems. While keto diarrhea usually resolves itself as the body adapts to the new diet, it can be a long-term side effect for some individuals.

High fat content

The keto diet is a high-fat, low-carb, and moderate-protein eating plan. The diet is designed to send the body into a state of ketosis, where it uses fat instead of carbohydrates for energy. While this can be an effective way to lose weight, it can also lead to some unfortunate gastrointestinal (GI) symptoms, such as keto diarrhea.

The high-fat content of the keto diet can be a common cause of keto diarrhea. Fat takes longer to break down and digest compared to carbohydrates or protein. When switching to a high-fat diet like keto, the digestive system may struggle to keep up, leading to malabsorption of fats. This can result in steatorrhea, a type of diarrhea characterised by loose, watery stools with a high amount of fat content.

The increased fat intake can also impact the production of bile, a natural laxative produced by the liver to aid in fat digestion. The shift from low to high bile production can be challenging for the body, and if the bile is not properly reabsorbed, it can lead to diarrhea. Additionally, the high-fat content can affect the gut microbiome, leading to changes in gut bacteria and potentially causing diarrhea.

To manage keto diarrhea caused by high-fat content, it is recommended to:

• Supplement with ox bile or digestive enzymes to aid in fat digestion.
• Ensure adequate intake of fat-soluble vitamins, such as vitamin A and vitamin D, which are important for bile production.
• Monitor protein intake, as excessive protein can also contribute to diarrhea.
• Choose the right sources of dietary fat. Avoid excessive consumption of ultra-saturated fats like MCT-rich coconut oil, which can speed up transit time and trigger diarrhea. Prioritize mono-unsaturated and saturated fats from sources like olive oil, avocado, nuts, seeds, and high-fat dairy.
• Stay properly hydrated, as dehydration can worsen diarrhea and impact weight loss.
• Consume bone broth, which provides essential electrolytes and amino acids that may help prevent diarrhea.
• Engage in gentle exercises like yoga or brisk walks, which can help regulate bowel health and reduce the frequency of diarrhea.

Lack of fibre

The keto diet is a high-fat, low-carb, and moderate-protein diet. It is a popular weight-loss strategy, but it can also lead to gastrointestinal issues such as diarrhoea. One of the reasons for this is a lack of fibre, which is crucial for gut motility and function.

Why Fibre is Important

Fibre is essential for healthy digestion. It helps to bulk up stools and prevent diarrhoea. It also promotes the growth of good bacteria in the gut, which can be disrupted by a high-fat diet like keto.

The Keto Diet and Fibre Intake

The keto diet restricts carbohydrates, which are a significant source of fibre. This means that people on the keto diet may not be getting enough fibre, leading to digestive issues.

Sources of Fibre on the Keto Diet

Some high-fibre foods that are suitable for the keto diet include greens, cucumber, broccoli, and cabbage, nuts, seeds, leafy greens, and cruciferous vegetables. Citrus fruits, berries, avocado, and chia seeds are also good sources of soluble fibre, which can help to calm diarrhoea.

Easing into the Keto Diet

To avoid digestive issues, it is recommended that people ease into the keto diet rather than making a sudden change. This gives the body time to adjust to the new way of eating and may help to prevent diarrhoea and other gastrointestinal problems.

When to See a Doctor

If diarrhoea is severe or lasts longer than a week, it is important to consult a doctor. Chronic diarrhoea can lead to health complications such as vitamin deficiencies, muscle deterioration, and electrolyte imbalance.

Artificial sweeteners

• Sucralose (Splenda)
• Xylitol
• Erythritol
• Stevia

While artificial sweeteners can be a good alternative to sugar for people on low-carb or ketogenic diets, excessive consumption may lead to digestive issues such as diarrhoea. This is because artificial sweeteners like sorbitol, mannitol, and xylitol are part of a group of poorly digested sugars called FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), which can cause diarrhoea.

Therefore, while artificial sweeteners can be a helpful way to reduce sugar and carb intake, it is important to consume them in moderation to avoid potential digestive problems.

Gut microbiome changes

The gut microbiome is a complex community of microorganisms, including bacteria, fungi, viruses, and protozoa. These microorganisms play a crucial role in maintaining the gut's structural integrity, immune function, and metabolic homeostasis. The composition of the gut microbiome can be influenced by various factors, such as diet, age, genetics, and medication use.

Diarrhea is often associated with changes in the gut microbiome, known as dysbiosis. This dysbiosis can be caused by a disruption of the mucosal integrity and an imbalance in the microbial population, leading to an overgrowth of pathogenic bacteria. Probiotics, prebiotics, and synbiotics have been proposed as potential treatments for diarrhea, aiming to restore a healthy balance in the gut microbiome.

Probiotics

Probiotics are live microorganisms that provide health benefits to the host. Species of Lactobacillus, Bifidobacterium, and Saccharomyces boulardii are commonly used as probiotics. They can reduce the severity of pathogen infections and alleviate diarrhea by producing antimicrobial substances, competing for nutrients, and excluding pathogenic bacteria. Probiotics can also strengthen the gut mucosal barrier and modulate the immune system.

Prebiotics

Prebiotics are substances that are selectively utilized by the gut microbial flora, promoting the growth of beneficial bacteria such as Lactobacilli and Bifidobacteria. They can increase the production of short-chain fatty acids (SCFAs), which are essential for maintaining gut barrier integrity. Prebiotics have been shown to reduce the duration of acute watery diarrhea and improve symptoms.

Synbiotics

Synbiotics are a combination of probiotics and prebiotics. They have been found effective in treating constipation and alleviating diarrhea by modulating the gut microbial composition and improving intestinal motility.

Fecal Microbiota Transplantation (FMT)

Fecal microbiota transplantation (FMT) is a procedure where the functional flora from a healthy donor's feces is introduced into the recipient's gastrointestinal tract to restore a healthy gut microbiome. FMT has been successful in treating refractory diarrhea and constipation, especially in cases of Clostridium difficile infection. However, FMT is associated with certain risks, and its use should be carefully considered.

In summary, gut microbiome changes play a significant role in the development and treatment of diarrhea. Probiotics, prebiotics, synbiotics, and FMT offer promising approaches to modulate the gut microbiome and alleviate diarrhea. However, further research is needed to fully understand the mechanisms and long-term effects of these interventions.

Bile acid malabsorption

There are three types of bile acid malabsorption:

• Type I: This occurs when there is a problem in the part of the small intestine (ileum) where re-absorption takes place. Causes include inflammation or removal of the ileum, due to conditions such as Crohn's disease or cancer treatment.
• Type II: This is when no definitive cause can be found and is known as primary bile acid malabsorption.
• Type III: This can result from other diseases or conditions within the abdomen, such as gallbladder removal, coeliac disease, chronic pancreatitis, radiotherapy, or small bowel bacteria overgrowth.

The main symptom of bile acid malabsorption is diarrhoea. When bile acids are not properly re-absorbed from the ileum, they pass into the large intestine (colon), irritating the lining and stimulating salt and water secretion. Diarrhoea may be frequent during the day and sometimes at night, and it may be pale, greasy, and hard to flush away, or unusually coloured (green, yellow, or orange). Other symptoms include bloating, cramping abdominal pain, and excessive wind.

There are two tests available in the U.S. for diagnosing bile acid malabsorption: the fecal bile acid test and the serum 7αC4 test. Treatment options include medication (such as Cholestyramine), surgery to remove the gallbladder, and diet changes, such as consuming less fat and increasing fiber intake.
