Keto And Flatulence: What's The Connection?

The ketogenic diet is a low-carb, high-fat, and moderate-protein diet. It is popular for its weight loss and health benefits, but it can also cause some unpleasant side effects, including flatulence.

The keto diet can cause flatulence due to various reasons, including dietary changes, increased consumption of sugar alcohols, insufficient water intake, and changes in gut bacteria. Dietary fiber intake can also play a role, as a sudden increase or decrease in fiber can lead to excessive fermentation and gas production in the gut.

While the keto diet offers benefits such as increased energy and mental clarity, it's important to be aware of potential drawbacks and take steps to mitigate them.

Dehydration

The keto diet's low-carb nature can also lead to an imbalance in electrolytes, causing dehydration. Carbohydrates help the body retain water and sodium, so when you eliminate carbs, you can easily lose necessary electrolytes through sweating. The risk of dehydration is higher when you first start the keto diet because your body is going through a lot of changes in how it handles water and electrolytes.

Some signs of dehydration on the keto diet include:

• Increased thirst
• Muscle cramps or spasms
• Fatigue and weakness
• Dizziness and lightheadedness
• Confusion or brain fog
• Kidney stones
• Urinary tract infections
• Kidney damage
• Constipation
• Headaches

To avoid dehydration on the keto diet, it is recommended to:

• Drink plenty of water throughout the day.
• Eat electrolyte-rich foods such as leafy greens, avocados, nuts, and seeds.
• Consume low-carb, water-rich whole foods like celery, tomatoes, cucumbers, and berries.
• Use a water tracking app or buy a daily water tracking bottle to monitor your water intake.
• Incorporate electrolyte supplements into your routine if you want to ensure you're getting enough.

Lack of fibre

Dietary fibre is crucial for digestion. It keeps food moving along the digestive tract. When you adopt a keto diet, your fibre intake may change significantly. In many cases, you may eat less fibre because you can no longer eat fibre-rich foods such as potatoes, bread, rice, pasta, and cereals.

With less fibre, food generally moves more slowly through the GI tract. This can cause the body to produce excessive gas, which leads to bloating.

However, it is also possible to increase your fibre intake on a keto diet, especially if you are consuming more low-carb, high-fibre vegetables. Eating too much fibre can also cause bloating, especially if your body is not used to it.

To prevent bloating, it is important to include foods that are high in fibre, such as nuts, seeds, avocados, and some non-starchy vegetables like broccoli and cauliflower. However, these should be introduced in small amounts to see if they agree with your body.

If you think you have increased your fibre intake too much, it may be helpful to cut back slightly and see if the bloating improves. Practicing mindful and healthy eating can also help you identify which high-fibre foods cause discomfort.

It is also important to drink enough water when increasing your fibre intake. Without enough water, you may end up constipated and gassy.

Food intolerances

Common keto-friendly foods that may trigger intolerances include peanuts, almonds, chocolate, cheese, cream, eggs, artificial sweeteners, and seafood. The low-carb and low-fibre nature of the ketogenic diet can exacerbate these issues, as poor digestion can cause unpleasant symptoms like bloating, nausea, and gas.

To address potential food intolerances, try eliminating the suspected food from your diet for a few weeks and monitor any improvements in symptoms. If your symptoms subside, it may be best to avoid that food in the future. Alternatively, consulting an allergist for testing can provide a quicker answer to your food intolerance concerns.

Some people also find that they have an intolerance to raw vegetables, which can cause worse gas than cooked vegetables. Broccoli, for example, is a common trigger for gas and bloating.

Lactose intolerance is another common food intolerance that can cause bloating and gas. Young cheeses, like mozzarella, are associated with gas and other lactose-intolerance problems because they have large amounts of lactose, like fresh milk. More aged cheeses have fewer of these effects because the ageing process removes the lactose.

Excessive MCT oil consumption

Flatulence is a common side effect of the keto diet, and this can be caused by excessive MCT oil consumption. MCT stands for medium-chain triglycerides, which are naturally occurring fats with shorter fatty acid chains than most other fats. MCT oil is often used by those on the keto diet as it can boost fat-burning, energy, and performance. However, excessive consumption can lead to several side effects, including gastrointestinal issues.

One of the most common side effects of taking too much MCT oil is flatulence, along with stomach ache, cramping, and diarrhoea. This is usually a sign that your gut microflora is imbalanced. MCT oil can also cause constipation, indicating that your elimination channels are sluggish and your bowels are struggling to get rid of toxins efficiently.

To avoid these issues, it is recommended to start with a small dose of MCT oil and gradually increase it. It is also important to stay hydrated and ensure you are consuming enough fibre in your diet.

In addition to gastrointestinal issues, excessive MCT oil consumption can also lead to other side effects such as immune reactions, brain fog, tiredness, and excessive fat accumulation in the liver. It is important to be aware of these potential side effects and consult a healthcare professional if you have any concerns.

Overall, while MCT oil can be beneficial for those on the keto diet, excessive consumption can lead to several side effects, including flatulence. It is important to introduce MCT oil gradually and be mindful of the amount consumed to avoid these issues.

High sugar alcohol intake

Sugar alcohols are often used as a substitute for real sugar in sweet, low-carbohydrate foods. Unlike real sugar, sugar alcohols are not fully absorbed by the body, leading to excessive consumption. Some common sugar alcohols include xylitol, sorbitol, and erythritol, which can be identified by the suffix "-ol" in the ingredient name.

Sugar alcohols are linked to irritable bowel syndrome (IBS) and flatulence, according to a 2016 study in the International Journal of Dentistry. They can also cause diarrhea if consumed in large amounts. This is because sugar alcohols are fermented by gut bacteria when they reach the large intestine, leading to bloating.

To avoid gastrointestinal distress, it is recommended to cut down on packaged foods and focus on incorporating more whole foods into your diet. Reading food labels is important to identify sugar alcohols and reduce their consumption.

Additionally, it is worth noting that even artificially sweetened foods containing sugar alcohols can make it difficult to curb sugar cravings in the long run.
