The ketogenic diet has been associated with several health benefits, including the reversal of chronic diseases such as type 2 diabetes, gout, and obesity. However, there are concerns about potential nutrient deficiencies, particularly thiamine (B1) deficiency, which can undermine the effectiveness of the diet and negatively impact health. Thiamine is essential for digesting proteins and fats, and a deficiency can lead to symptoms like blurry vision and neuroinflammation. While the ketogenic diet reduces glucose intake, which can improve thiamine levels, it is important to ensure adequate thiamine intake to prevent potential health issues.

Thiamine deficiency symptoms
Thiamine, also known as vitamin B1, is a vital nutrient that supports various bodily functions. A thiamine deficiency can lead to a range of symptoms, some of which can be vague and easily overlooked. Here are some of the key thiamine deficiency symptoms:
Fatigue and Loss of Appetite
One of the most common signs of thiamine deficiency is fatigue. Those with low thiamine levels may experience persistent tiredness and a lack of energy. Thiamine deficiency can also cause a decrease in appetite, leading to unintended weight loss.
Neurological Issues
Thiamine plays a crucial role in brain health. A deficiency can lead to neurological symptoms such as irritability, poor memory, sleep disturbances, and behavioural changes. In severe cases, it may result in nerve damage, confusion, apathy, difficulty walking, eye problems, and even paralysis.
Cardiovascular Problems
Thiamine is essential for maintaining a healthy cardiovascular system. A thiamine deficiency can negatively impact the heart, causing abnormalities such as an increased heart rate and widened blood vessels. If left untreated, it can lead to heart failure and congestion in the lungs.
Weakness and Muscle Atrophy
Thiamine deficiency can lead to muscle weakness and pain, particularly in the legs. This can progress to muscle wasting or atrophy, impacting the arms as well.
Skin and Sensory Changes
Some people with thiamine deficiency experience a prickling or "pins-and-needles" sensation in their toes and a burning sensation in their feet, especially at night. The skin may also become warm and moist due to the dilation of blood vessels.
It is important to note that thiamine deficiency is typically treated with thiamine supplements, and severe cases may require intravenous administration. Additionally, thiamine deficiency is associated with low-carbohydrate ketogenic diets, and supplementation may be necessary to correct this.

Thiamine-rich foods
Thiamine, or vitamin B1, is a water-soluble vitamin found naturally in some foods, added to foods, and sold as a supplement. It is essential for life and plays a vital role in the growth and function of various cells. A thiamine deficiency can manifest in several ways, including blurry vision, confusion, loss of muscle coordination, peripheral neuropathy, and more.
A thiamine deficiency can undermine a ketogenic diet, as thiamine is needed to digest proteins and fats. It is a cofactor for two important enzymes in glucose metabolism: pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase. Additionally, thiamine is necessary to break down amino acids such as leucine, valine, and isoleucine, which are used for energy metabolism, cholesterol synthesis, and neurotransmitter synthesis.
- Liver: Beef liver provides about 14% of the daily value of thiamine, while other sources mention pork chop as having the highest level of B1, with a 6-ounce pork chop providing 96% of the daily recommended value.
- Salmon: A cooked salmon fillet provides about 18% of the daily value of thiamine, while other sources state a 6-ounce fillet contains 48% of the daily recommended value.
- Flax seed meal: Although it contains less thiamine than the above options, it is mentioned as a distant third to pork chop and salmon.
- Fortified foods: In industrial countries, fortified foods provide about 50% of the total thiamine intake. This includes fortified breakfast cereals and grains that have undergone processing, such as refined white bread and rice.
While severe thiamine deficiencies may require supplementation, it is important to note that a thiamine deficiency is rare in the US, as most people meet the RDA through their diets.

Thiamine and mental health
Thiamine, also known as vitamin B1, is an essential nutrient for human health. It plays a crucial role in energy metabolism and is particularly important for the proper functioning of the nervous system, including the brain.
Thiamine deficiency has been linked to various neurological and psychiatric conditions, including mental disability, seizures, structural abnormalities in the central nervous system, and spasticity. In severe cases, thiamine deprivation can lead to fatal lactic acidosis in newborns, while milder cases can result in neurological issues such as Wernicke-Korsakoff syndrome (WKS), which causes severe memory loss, hallucinations, and permanent brain damage. Additionally, thiamine deficiency has been associated with an increased risk of developing neurodegenerative diseases and mood disorders, including depression.
A ketogenic diet, which is high in fat and low in carbohydrates, has been found to be associated with lower thiamine intake and status. This is because thiamine is needed to digest and metabolise proteins and fats efficiently. When starting a ketogenic diet, individuals may already have micronutrient deficiencies, especially if they have a history of psychiatric medication, poor health, substance abuse, or life stressors, all of which deplete thiamine levels. Therefore, thiamine supplementation may be necessary to ensure adequate levels and prevent potential negative mental health consequences.
However, it is important to note that thiamine supplementation alone may not be sufficient to address all mental health concerns. While it can help improve mood and reduce neuroinflammation, it should be combined with other treatments such as psychotherapy and medication for a comprehensive approach to managing mental health. Additionally, a well-rounded diet that includes thiamine-rich foods such as beef, pork, eggs, liver, nuts, oats, oranges, seeds, legumes, and yeast can help improve overall thiamine levels and support mental well-being.

Thiamine and weight loss
Thiamine, also known as vitamin B1, is a vital nutrient for all living organisms. It is a precursor to thiamine pyrophosphate (TPP), a coenzyme that plays a crucial role in energy metabolism and several other biological processes.
Thiamine deficiency has been linked to obesity in several studies. For instance, a study on mice found that a high-fat, high-fructose diet induced obesity, but this was ameliorated by high-dose thiamine supplementation. The mechanism behind this may be thiamine's role in enhancing oxidative catabolism and reducing whole-body fat and weight. Another study found that obese individuals tended to have deficiencies in multiple nutrients, including thiamine, possibly due to decreased absorption, increased excretion, or higher physiological requirements.
Ketogenic diets, which are high in fat and low in carbohydrates, have been associated with lower thiamine intake and status. This is partly due to the reduced consumption of thiamine-rich foods, such as whole grains. Additionally, thiamine is needed to digest proteins and fats, so adequate thiamine levels are crucial for those on a ketogenic diet to fully utilise the nutrients they are consuming.
Some studies have investigated the impact of thiamine on weight loss. One study compared a high-protein, high-thiamin weight-loss diet with a high-carbohydrate, adequate-thiamin diet in overweight or obese individuals with type 2 diabetes. Both groups lost similar amounts of weight, but the high-thiamin group maintained their erythrocyte thiamin amounts, while the adequate-thiamin group showed a decrease. Another study on sheep found that high-dose thiamine treatment had no effect on weight gain or body weight, but it did increase plasma concentration of non-esterified fatty acids, indicating a shift towards utilising fatty acids as an energy source.
In summary, thiamine plays a crucial role in energy metabolism and maintaining intestinal homeostasis. Thiamine deficiency has been linked to obesity, and supplementation with thiamine may help prevent obesity induced by high-fat, high-fructose diets. While ketogenic diets can lead to lower thiamine intake, thiamine is necessary for breaking down proteins and fats, so ensuring adequate thiamine levels is important for those on these diets. Some studies suggest that thiamine may aid in weight loss, but more research is needed to confirm this.

Thiamine and neurological disorders
Thiamine, also known as vitamin B1, is an essential nutrient that serves as a cofactor for several enzymes, primarily with mitochondrial localisation. Thiamine is involved in energy metabolism and the biosynthesis of nucleic acids, and it also plays a role in the antioxidant machinery.
The brain is highly vulnerable to thiamine deficiency due to its heavy reliance on mitochondrial ATP production. Thiamine deficiency can lead to a range of neurological and psychiatric symptoms, including mild symptoms such as confusion, reduced memory, and sleep disturbances, as well as more severe symptoms such as encephalopathy, ataxia, congestive heart failure, muscle atrophy, and even death.
In the context of ketogenic diets, thiamine deficiency can undermine the potential benefits of the diet for mental health. Thiamine is needed to digest proteins and fats, and it is required to unlock the glucose that the body makes. The more glucose we consume, the more thiamine we need. Therefore, reducing glucose intake through a ketogenic diet can be beneficial for thiamine levels. However, it is important to note that thiamine deficiency can also occur with ketogenic diets, especially if the diet is highly processed and lacking in micronutrients.
For individuals using the ketogenic diet to support their mental health, thiamine supplementation may be necessary to ensure they receive the full benefit of the lifestyle change. This is particularly important for individuals recovering from psychiatric disorders, as their brains are using up nutrients like thiamine at a faster rate to repair existing damage.
Thiamine supplementation has been found to be beneficial in the management of neurological disorders, especially in the paediatric population. For example, thiamine-responsive megaloblastic anemia (TRMA) or Rogers syndrome is a rare condition that can be treated with high doses of thiamine. Additionally, the biotin-thiamine-responsive basal ganglia disease (BTBGD) is a neurometabolic autosomal recessive disorder that has shown improvement with thiamine supplementation.
