The carnivore diet, also known as the lion diet or animal-based diet, is a diet that includes animal products such as beef, butter, bacon, and eggs, while minimizing or cutting out fruits and vegetables. Some people on this diet have reported changes in their body odor, with some claiming that their body odor disappeared, while others have noticed an increase in body odor, describing it as a sour milk or untreated leather goods type of smell. While the diet has gained popularity among fitness influencers, some doctors warn that it may be unhealthy in the long run due to the lack of fiber, carotenoids, and polyphenols found in fruits and vegetables.

What You'll Learn

Body odour varies depending on diet
The carnivore diet has gained popularity, particularly among fitness influencers, who claim various benefits such as weight loss, clearer skin, improved gut health, and better overall health. However, the diet has also been criticised by doctors as potentially unhealthy in the long run due to the lack of fibre, carotenoids, and polyphenols found in fruits and vegetables.
Those who have tried the carnivore diet have reported mixed results when it comes to body odour. Some people claim that their body odour has improved or even disappeared while on the carnivore diet. They attribute this improvement to the elimination of odour-causing foods like onions, garlic, and dairy from their diet. These foods are known to produce pungent body odours that can be offensive to some individuals.
On the other hand, some people have noticed an increase in body odour while following the carnivore diet. One explanation could be the high amounts of saturated fat and cholesterol found in meat. As the body breaks down these fats, it may release volatile compounds through the skin, resulting in a stronger body odour. Additionally, the process of detoxifying and weight loss, which is common at the beginning of a new diet, can lead to increased sweating and more pronounced body odour.
It is worth noting that the change in body odour may be temporary, as the body adjusts to the new diet. Additionally, individual factors such as weight, bacteria, and toxin levels can influence the intensity of body odour during this detox process. While the carnivore diet may not be the sole cause of bad body odour, it is important to consider the potential impact of dietary changes on body scent.

Carnivore diet may cause bad body odour
The carnivore diet, which involves eating only meat and minimising or cutting out fruit and vegetables, has become popular among fitness influencers. However, some people report that the diet has caused them to experience bad body odour. One possible explanation for this is the absence of vegetables in the diet, which can alter body odour. For example, eating onions is said to produce an "onion-like" smell when sweating.
Additionally, the process of losing weight and detoxing, which can be accelerated by the carnivore diet, may cause stronger body odour in the short term. This is due to increased sweating and the release of toxins through the pores. The type of fat and meat consumed in the carnivore diet, such as beef tallow, may also contribute to body odour. Some people have reported a "sour milk" or "untreated leather goods" smell, which could be related to the breakdown of proteins and fats in the diet.
While some carnivore dieters claim improved skin and gut health, the lack of fibre, carotenoids, and polyphenols from fruits and vegetables can negatively impact gut health and increase the risk of developing depression. The diet may also contribute to higher chances of premature death, cardiovascular disease, and cancer, according to a 2012 Harvard study.
To mitigate body odour, some people on the carnivore diet recommend taking cold showers and using aluminium-based deodorants to prevent sweating. However, it is important to note that aluminium can clog skin pores, hindering the body's natural release of toxins. Finding a healthy balance in one's diet and consulting a healthcare professional or nutritionist may be advisable to ensure adequate nutrition and minimise potential negative side effects, such as body odour.

Weight loss may be a factor in body odour
The carnivore diet is a controversial eating pattern that cuts out fruits and vegetables and focuses on meat, butter, bacon, and eggs. While some adherents claim clearer skin and improved gut health, doctors warn of potential long-term health risks. One purported benefit of the carnivore diet is weight loss, which is often linked to reduced caloric intake due to the exclusion of carbohydrates.
Weight loss is a factor in body odour, and individuals with higher body weight tend to experience more noticeable body odour. This is because the additional exertion required for physical tasks can lead to increased sweating. Furthermore, sweat may become trapped in thicker skin layers, providing an ideal environment for bacteria to proliferate.
Bacteria on the skin, particularly in areas with a high concentration of apocrine glands such as the underarms and scalp, can mix with sweat and produce body odour. This odour can vary in scent, ranging from sweet to sour to tangy. While the amount of sweat does not directly influence body odour, certain conditions, such as hyperhidrosis, can lead to excessive sweating and increase the likelihood of body odour.
During weight loss, individuals may experience changes in their body odour due to fluctuations in hormone levels and dietary shifts. For example, a low-carbohydrate diet can lead to elevated levels of ketones, which can result in an alcohol-like odour. Additionally, high-protein diets can produce a bleach or ammonia scent, indicating that muscle, rather than fat, is being metabolised for energy, potentially slowing down the metabolism.
It is important to note that body odour can also be influenced by factors beyond weight loss and diet. Stress and anxiety can impact body odour by affecting sweating and bacterial activity. Additionally, specific medical conditions, such as kidney or liver disease, diabetes, and bacterial overgrowth on the skin, can contribute to unusual body odours.

Detoxing and bacteria may cause stronger smells
Body odour is caused by a mix of bacteria and sweat on the skin. The type of bacteria on your skin and how it interacts with your sweat determines the odour. Sweat itself does not have a smell, but when it comes into contact with the bacteria on your skin, it can produce an odour.
The carnivore diet, which involves eating primarily meat and animal products, can lead to changes in body odour. While some proponents of the diet claim that it improves their skin and gut health, there are reports of increased body odour, with some describing it as a "sour milk" or "untreated leather goods" type of smell.
Detoxing and changes in bacteria levels may be factors in the increased body odour associated with the carnivore diet. During a detox, the body aims to eliminate excess chemicals, heavy metals, bacteria, and other toxins through sweat and glands in the armpits and groin area. This can result in stronger body odours, including bad breath. Additionally, meat and animal products can be acidic and hard to digest, providing a food source for bacteria in the colon, which may contribute to body odour.
Furthermore, weight loss is a common aspect of the carnivore diet, and individuals with more weight to lose may experience stronger body odours during the initial stages of the diet. This is because they may have a higher amount of bacteria and toxins to eliminate through the detox process.
To manage body odour, maintaining dry skin can help, as bacteria struggle to breed in dry areas. Antibacterial soaps can also reduce odour-causing bacteria. While some individuals on the carnivore diet avoid deodorant, using an antiperspirant with aluminium chloride can help manage sweat and reduce body odour.

Health risks associated with the carnivore diet
The carnivore diet, also known as the "zero carb" diet, is a restrictive eating plan that involves consuming only animal products and a few other items. It cuts out fruits, vegetables, grains, legumes, seeds, and nuts. While some proponents of the diet claim various benefits, there are several health risks associated with it:
Nutrient deficiencies: The carnivore diet is lacking in several essential nutrients found primarily in plant-based foods, including dietary fiber, vitamins A, C, and B12, carotenoids, and polyphenols. Fiber is crucial for gut health, lowering cholesterol, stabilizing blood sugar, and reducing the risk of colon cancer. Long-term, plant-rich diets have been associated with a decreased risk of certain health conditions like Alzheimer's, heart disease, and Type 2 diabetes.
Increased risk of cancer: A diet high in red and processed meats has been linked to an increased risk of cancer, particularly colon, rectal, and colon cancer. A 2012 Harvard study found that participants who consumed the most red meat were more likely to die younger and from cardiovascular disease and cancer.
High cholesterol and heart disease: Animal fats, which are predominantly saturated, can raise LDL ("bad") cholesterol levels. This is a concern for all keto diets, including the carnivore diet, and can contribute to an increased risk of heart disease.
Kidney problems: The very high protein intake associated with the carnivore diet can lead to impaired kidney function and an increased risk of kidney stones.
Weight loss concerns: While the carnivore diet may lead to initial weight loss due to reduced carbohydrate intake, it is not a sustainable or healthy way to lose weight in the long term.
Body odor changes: Some individuals on the carnivore diet have reported changes in their body odor, describing it as a sour milk or untreated leather-like smell. This may be due to the absence of certain vegetables known to influence body odor, such as onions, or the result of the body detoxifying and releasing toxins through the pores.
While the carnivore diet may offer some benefits, it is important to approach it with caution due to the potential health risks outlined above. The diet lacks long-term research, and making small, gradual improvements to one's diet is generally a more sustainable and healthier approach.
