The Stinky Truth About Keto Farts: Why So Foul?

The ketogenic diet is a low-carb, high-fat diet that has become popular for its presumed miraculous effects on energy, blood sugar management, appetite control, and mental focus. However, one of the less desirable side effects of this diet is the occurrence of keto farts, which are known to be particularly smelly. So, why do keto farts smell so bad?

Keto farts are caused by excess protein consumption

The ketogenic diet is a low-carbohydrate, high-fat diet that restricts your carb intake to about 20-50 grams per day. In a typical ketogenic diet, 70% of your calories come from fats, 20% from proteins, and 10% from carbs. However, the keto diet can be customized, and the daily carb intake can vary from 20 grams to 50 grams depending on how your body processes carbs.

When your body switches to burning fat as its primary fuel source, it starts producing ketones, which are released in the breath, resulting in what is known as "keto breath" or "dragon breath." Similarly, excess protein consumption can also lead to bad breath as the breakdown of high amounts of protein produces ammonia, which is released through the breath.

Excess protein consumption on the keto diet can also contribute to gastrointestinal issues, including both diarrhea and constipation, commonly known as "keto farts." While protein itself does not directly increase flatulence, protein supplements and powders often contain other substances that can cause increased gas and bloating. For example, whey protein and casein supplements may contain high amounts of lactose, which can increase flatulence even in individuals who typically consume dairy products without issues.

Additionally, protein powders may contain additives such as thickeners and sweeteners like sorbitol, which can further contribute to flatulence. Plant-based protein sources, such as beans, grains, and legumes, can also lead to increased gas production.

To summarize, while the keto diet is primarily focused on reducing carbohydrate intake, it is important to be mindful of excess protein consumption as it can lead to unpleasant side effects, including bad breath and gastrointestinal issues such as keto farts.

They can be coupled with looser stools and diarrhoea

The ketogenic diet is a low-carb, high-fat diet that can lead to some gastrointestinal issues. One of these issues is keto farts, which are often coupled with looser stools and diarrhoea. This occurs because the keto diet is 70% to 80% fat, and some people's bodies don't digest or put all of this fat to use. This undigested fat comes out in the stool, making it more fluid than usual.

Additionally, many keto-friendly foods contain non-nutritive sweeteners or sugar alcohols, such as sorbitol or xylitol, which are used to replace sugar. These can also cause digestive problems, including diarrhoea. Sorbitol, in particular, is known for causing gastrointestinal upset and can lead to cramping, bloating, and diarrhoea.

The high-fat content of the keto diet can also cause slower stool movement through the gastrointestinal tract. This means that the stool sits in the body for longer and can putrefy more easily, especially if the person is consuming a lot of protein. This can further contribute to the looser stools and diarrhoea experienced by some people on the keto diet.

While these issues are common when starting the keto diet, they are usually temporary and will resolve as the body adjusts to consuming higher amounts of fat. Staying hydrated and increasing fibre intake can also help to alleviate these issues. However, if the diarrhoea persists or becomes a concern, it may be necessary to consult a healthcare professional or consider a different dietary plan.

They can be caused by eating too much cheese

Cheese is a dairy product, and dairy products contain a sugar called lactose. Many people are lactose intolerant, meaning their bodies cannot properly digest lactose. When lactose isn't digested, it sits in the gut and decomposes, causing foul-smelling gas.

Lactose intolerance is one of the most common food intolerances that may cause smelly farts. If you are lactose intolerant, you may also experience nausea, vomiting, stomach cramps, and bloating.

Young cheeses, like mozzarella, are particularly associated with gas and other lactose-intolerance problems because they have large amounts of lactose, like fresh milk. More aged cheeses have less of these effects because the lactose has been removed by the enzymes and bacteria aging process.

If you are lactose intolerant, you may want to avoid or limit your consumption of milk-based foods such as yoghurt, ice cream, and cheese, as well as other lactose-containing foods like lunch meats, coffee creamers, and salad dressings.

They can be caused by eating foods with sugar alcohols

The ketogenic diet is a low-carbohydrate, high-fat diet. It involves restricting your carb intake to about 20-50 grams per day. This extreme reduction in carbs forces your body to rely on ketone bodies (produced from the breakdown of fats) instead of glucose from carbs.

The keto diet can cause bad-smelling flatulence, or "keto farts", for several reasons. One of these reasons is the consumption of foods containing sugar alcohols.

Sugar alcohols are low-calorie sweeteners that are often found in diet products. Sugar alcohols include:

• Erythritol
• Sorbitol
• Xylitol
• Mannitol
• Isomalt

Your body cannot fully absorb these sugar alcohols, so they remain in your gut. This can lead to the production of gas that smells bad.

Sugar alcohols are just one of several food groups that can cause keto farts. Other food groups include:

• High-fibre foods, such as strong-smelling vegetables (e.g. broccoli, Brussels sprouts, cauliflower, and cabbage)
• Dairy products, for those who are lactose intolerant
• High-fructose corn syrup
• Garlic, onions, and wheat
• Beans and legumes
• Pitted fruits (e.g. cherries, apples, and avocados)
• Alcohol, such as beer and wine
• Protein powders

In addition to diet, keto farts can also be caused by constipation, medications (especially antibiotics), infections, and digestive issues.

They can be caused by eating too much oil

The ketogenic diet is a low-carbohydrate, high-fat diet that requires you to restrict your carb intake to about 20-50 grams per day. In a typical ketogenic diet, 70% of your calories come from fats, 20% from proteins, and 10% from carbs. This extreme reduction in carbs forces your body to rely on ketone bodies (produced from the breakdown of fats) instead of glucose from carbs.

When your body switches to burning fat as its primary fuel source, your body starts producing ketones, which are released in the breath. This is typically more noticeable when beginning a ketogenic diet. Eating too much protein can also cause bad breath because when your body breaks down high amounts of protein, it produces ammonia, which is also released through the breath.

The standard keto diet should only contain about 20% protein, so adjusting your protein intake should do the trick. However, it is worth noting that some people on the keto diet have reported an increase in body odor, including body odor, and foul-smelling flatulence.

The keto diet can cause some gastrointestinal issues for some people. This can be in the form of both extremes: diarrhea and constipation. This is usually temporary and will resolve itself when the body adjusts to consuming higher amounts of fat.

If you are experiencing foul-smelling flatulence, this could be due to the high amount of oil in your diet. Oil is a type of fat, and the keto diet is already very high in fat. If you are consuming too much oil, this could be causing an upset in your digestive system, leading to foul-smelling flatulence.

To reduce the occurrence of foul-smelling flatulence, it is recommended that you reduce your intake of oil and other fats and increase your consumption of high-fiber foods. High-fiber foods are good for your overall health and well-being, but they can be difficult to digest. They break down slowly in the digestive tract, which can lead to the production of odorous gas.

Additionally, it is important to drink plenty of water, as dehydration can also contribute to foul-smelling flatulence. Making these dietary changes should help reduce the occurrence of foul-smelling flatulence caused by consuming too much oil.
