Keto Flu Diarrhea: What's The Connection?

The ketogenic diet is a popular, effective, and quick way to lose weight. It involves eating a low-carbohydrate, high-fat, and moderate-protein diet. While it is considered safe for most people, it is associated with some unpleasant side effects, including keto flu. Keto flu is a collection of symptoms, including diarrhea, experienced by some people when they start a ketogenic diet. The drastic reduction in carbohydrates can be a shock to the body, causing withdrawal-like symptoms. The keto flu usually lasts for a few days to several weeks, but for some people, it may last up to a month.

Diarrhea can be a symptom of keto flu

The keto diet is a popular, effective way to lose weight. It is a low-carb, high-fat, and moderate-protein eating plan that forces the body to burn fat for energy instead of glucose. While it has been shown to help people lose weight, it can also lead to gastrointestinal (GI) issues, such as diarrhea and constipation.

Diarrhea is a common side effect of the keto diet, and it can be caused by various factors. One reason may be that the keto diet is very high in fat, and fat can be hard for the body to digest. The high-fat content of the keto diet may also lead to an increase in bile production by the liver, which can act as a natural laxative and speed up the passage of waste through the digestive tract. Additionally, the keto diet can disrupt the gut microbiome, which is essential for digestion and overall health.

Another factor contributing to diarrhea on the keto diet is the use of artificial sweeteners and sugar alcohols. These are often used as low-carb alternatives to sugar, but they can have a laxative effect and cause gastrointestinal distress. Consuming too much protein on a keto diet can also lead to diarrhea.

For most people, keto diarrhea is a temporary issue that occurs during the initial transition period to the diet. However, for some, it may be a long-term side effect. It is important to stay hydrated and replenish electrolytes if experiencing diarrhea on the keto diet, as there is an increased risk of dehydration. Consulting a healthcare professional is advised if diarrhea is severe or lasts longer than a week.

To alleviate keto diarrhea, it is recommended to increase fiber intake, drink more water and electrolytes, and reduce consumption of artificial sweeteners and sugar alcohols. Easing into the keto diet by gradually reducing carbs and increasing fats may also help to prevent GI issues.

Diarrhea is caused by the body adjusting to a high-fat diet

Diarrhea is a common side effect of the keto diet, which is a low-carb, high-fat eating plan. The diet consists of less than 5% carbs, 10-30% protein, and 65-90% fat. This drastic change in diet can cause an imbalance in the gut microbiome, as the gut feeds off short-chain fatty acids found in grains, fruits, and vegetables, which are limited on the keto diet.

When an individual consumes too much fat, the body can struggle to break it down and absorb it. This can lead to an increased amount of unabsorbed fat reaching the small intestines and colon, pulling in more water to help its passage, resulting in watery diarrhea. This is a permanent side effect for some people on the keto diet.

In addition to the high-fat content, there are a few other reasons why the keto diet may lead to diarrhea:

• Artificial sweeteners and sugar alcohols: These are often used as low-carb alternatives to sugar but can have a laxative effect when they reach the large intestine undigested.
• Gut microbiota: A 2019 study found that high-fat diets might cause inflammation of the digestive tract, a decrease in healthy fatty acids, and unfavorable changes in the gut microbiome.
• Bile production: A diet high in fat requires the liver to release extra bile, which is a natural laxative. An excessive amount of bile may push waste through the digestive tract faster, leading to diarrhea.
• Dairy consumption: As whole dairy products are high in fat, people starting the keto diet may consume more of these and may discover an intolerance to dairy, with common symptoms including diarrhea, bloating, and gas.

While the keto diet can lead to diarrhea, there are some strategies that may help to relieve these symptoms:

• Easing into the diet: Gradually reducing carbs and increasing fats may help the body adapt better.
• Staying hydrated: Drinking water and sugar-free electrolyte beverages can help replace lost fluids and electrolytes.
• Eating more fiber: Increasing fiber intake with nuts, seeds, leafy greens, and cruciferous vegetables can help relieve diarrhea.
• Reducing dairy intake: Dairy is known to cause GI upset, so removing cream and cheese from the diet may help improve diarrhea symptoms.
• Probiotics and prebiotics: Taking a probiotic supplement or increasing the intake of probiotic- and prebiotic-rich foods may support gut bacteria and reduce GI effects.

It is important to note that if diarrhea is severe or persists for more than a week, it is recommended to consult a doctor. Chronic diarrhea can lead to health complications such as vitamin deficiencies, muscle deterioration, and electrolyte imbalance.

Artificial sweeteners and sugar alcohols can cause diarrhea

Diarrhea is a common side effect of the keto diet, and artificial sweeteners and sugar alcohols are often to blame.

Artificial sweeteners such as sorbitol, maltitol, xylitol, and mannitol are popular among those on the keto diet because they are non-nutritive sugars that help limit carbs. However, because sugar alcohols are not effectively absorbed in the gut, they often reach the large intestine undigested, causing a laxative effect. This can lead to diarrhea, as well as other unpleasant symptoms such as gas and nausea.

Sugar-free and low-carb products frequently contain these sugar alcohols to give them a sweet taste without adding table sugar. While these sweeteners are generally considered safe, consuming them in excess can cause digestive issues.

To avoid diarrhea caused by artificial sweeteners and sugar alcohols, it is recommended to reduce the consumption of sugar-free beverages, candies, protein/diet bars, and sugar substitutes. Instead, opt for natural sweeteners or products that do not contain these sugar alcohols.

It is worth noting that diarrhea can also be caused by other factors when following a keto diet, such as consuming too much protein or the wrong sources of dietary fats. Additionally, the high-fat and low-carb content of the keto diet can lead to gastrointestinal symptoms like nausea and bloating.

If you are experiencing diarrhea or other gastrointestinal issues while on the keto diet, it is important to stay hydrated, increase your fiber intake, and consider easing into the diet slowly. If symptoms persist or become severe, it is recommended to consult a healthcare professional.

Diarrhea could be a long-term side effect

Diarrhea is a common side effect of the keto diet, and for some people, it could be a long-term issue.

The keto diet is a high-fat, moderate-protein, and very low-carbohydrate diet. This drastic reduction in carbohydrates can be a shock to the body, and the transition period can be challenging. The body typically uses carbohydrates as an energy source, but when there is a lack of carbohydrates, the body enters a state called ketosis, where it breaks down stored fat to create molecules called ketones, which are used as fuel.

The high-fat content of the keto diet can be difficult for some people to digest, and this may lead to diarrhea. The body needs time to adjust to breaking down and absorbing the increased amount of fat. If the fat is not adequately broken down and absorbed in the small intestine, it travels to the colon, where it is digested by bacteria, leading to gas, bloating, and fat in the stool.

Additionally, the keto diet can impact the gut microbiome, which has implications for digestion. Research has found that diets high in fat might cause inflammation of the digestive tract, a decrease in healthy fatty acids, and unfavourable changes in the gut microbiome. These changes in the gut bacteria can lead to poor digestion and diarrhea.

Artificial sweeteners and sugar alcohols, commonly consumed on the keto diet, can also cause gastrointestinal distress and diarrhea. Sugar alcohols are often used in sugar-free and low-carb products to provide a sweet taste without table sugar. However, the body does not effectively absorb these sugar alcohols, and they can have a laxative effect when they reach the large intestine undigested.

While diarrhea may not be as common as constipation on the keto diet, it is a potential long-term side effect for some individuals. If diarrhea persists or is severe, it is important to consult a healthcare professional.

Remedies include adding fiber and drinking water and electrolytes

Diarrhea is a common side effect of the keto diet, and it can be caused by a few factors. High-fat foods can be difficult for the body to break down and absorb, leading to watery diarrhea. Artificial sweeteners, such as sorbitol and xylitol, can also have a laxative effect and contribute to diarrhea. Additionally, a lack of fiber in the keto diet can result in constipation, another common issue for those on the keto diet.

To remedy these digestive issues, it is recommended to increase your fiber intake by consuming more nuts, seeds, leafy greens, and cruciferous vegetables. Staying hydrated is also crucial, as the keto diet can lead to dehydration. Drinking plenty of water and consuming electrolytes can help prevent dehydration and related issues.

It is important to note that chronic diarrhea can lead to health complications such as vitamin deficiencies, muscle deterioration, and electrolyte imbalances. If diarrhea persists or is severe, it is recommended to consult a doctor. They can help identify any underlying issues and provide guidance on a suitable diet.
