The ketogenic or keto diet is a low-carbohydrate, high-fat eating plan designed to shift the body's metabolism into a state called ketosis, where the body uses fat for fuel instead of carbohydrates. While the keto diet is popular for its weight loss and potential health benefits, some people experience sleep disturbances, or keto insomnia, when they start the diet. This may be due to the immediate shift to a low-carb diet leading to a reduction in sleep-regulating chemicals like melatonin and adenosine. However, not everyone on the keto diet will experience insomnia, and some studies have shown that the keto diet can lead to better sleep, especially for those who are overweight or obese. As such, it is important to understand the potential risks and side effects of the keto diet and consult a doctor before starting the diet. For those experiencing keto insomnia, there are keto-friendly sleep aids available, such as Som Sleep, which can help support a consistent sleep routine.

Keto insomnia and keto flu
The ketogenic or "keto" diet is a low-carbohydrate, high-fat eating plan designed to shift the body's metabolism into a state called ketosis, where the body primarily relies on fat for energy instead of carbohydrates. While the diet has gained popularity for weight loss and potential health benefits, some individuals starting the keto diet experience keto insomnia.
Keto insomnia refers to sleep disturbances that some people experience when adopting the keto diet. It is caused by the strict restriction of carbohydrates that the diet calls for, leading to a reduction in sleep-regulating chemicals like melatonin and adenosine. While this phenomenon is not universal, it can be frustrating to go without sleep when starting the diet.
To manage keto insomnia, it is recommended to adopt strategies to ease the transition and support good sleep hygiene. This includes making gradual changes to the diet, staying adequately hydrated, and incorporating sleep-friendly practices. Getting at least 30 minutes of natural light early in the day, maintaining a consistent sleep schedule, and ensuring proper nutrient intake are also helpful. It is important to note that keto insomnia is not life-threatening or dangerous, and it typically resolves as the body adjusts to the new diet.
The keto flu is a set of symptoms some people experience when starting the keto diet. These symptoms can include fatigue, muscle cramps, stomach discomfort, and diarrhea, which can be similar to the flu but without a fever. The keto flu is caused by the body adapting to a new diet consisting of very few carbohydrates, leading to a reduction in insulin levels and a shift in how cells use energy.
To manage the keto flu, it is important to stay hydrated and replace lost fluids, especially during diarrhea. Light activities like walking, yoga, or leisurely biking may improve symptoms. Reducing caffeine intake and creating a dark environment in the bedroom can also help with the sleep disturbances associated with the keto flu. These symptoms typically last a few days to a few weeks, and they are not indicative of something more serious.

Ketosis and sleep quality
The ketogenic or "keto" diet has gained popularity for its potential health benefits and weight loss. However, some people starting the keto diet experience keto insomnia, referring to sleep disturbances caused by the strict restriction of carbohydrates. While not everyone on the keto diet will experience insomnia, it is theorized that the immediate shift to a low-carb diet leads to a reduction in sleep-regulating chemicals like melatonin and adenosine.
According to a 2023 study, 65% of participants who followed a low-calorie keto diet for a month reported sleeping better. These improvements were linked to weight loss and other weight-related factors, which are known to impact sleep. The keto diet is not recommended for those with liver, pancreas, gallbladder, and thyroid conditions, as well as individuals who are pregnant or breastfeeding.
To manage keto insomnia, gradual changes to the diet, adequate hydration, and incorporating sleep-friendly practices are recommended. This includes getting at least 30 minutes of natural light early in the day and maintaining a consistent sleep schedule. While keto insomnia is a potential side effect for some, others experience improved sleep efficiency and counteraction of the decline in REM sleep after strenuous exercise.
Ketogenic dietary therapies have been found to improve overall sleep quality, reduce difficulty falling asleep, improve daytime sleepiness, and increase REM sleep. The diet's beneficial effects on sleep may be synergistic with its positive impact on medical conditions, such as epilepsy, autism spectrum disorder, and migraine. However, more research is needed to fully understand the impacts of keto on sleep and overall health.

Sleep-regulating chemicals
Sleep is an essential bodily function, and the quality and duration of sleep can be influenced by various factors, including one's dietary choices. The keto diet, known for its low-carbohydrate and high-fat composition, has been associated with both improvements and disturbances in sleep patterns. While some individuals on the keto diet experience "keto insomnia," others report enhanced sleep quality. This discrepancy underscores the complex relationship between diet and sleep, which involves the intricate interplay of various sleep-regulating chemicals in the brain.
One key sleep-regulating chemical is melatonin, a hormone produced by the body that helps regulate sleep-wake cycles. Melatonin is often referred to as the "sleep hormone" because its levels rise in the evening, making us feel sleepy, and decrease with exposure to light, helping us maintain alertness during the day. The production and release of melatonin are influenced by our exposure to light and darkness, following a circadian rhythm.
Another important chemical involved in sleep regulation is adenosine. Adenosine is a neurotransmitter that gradually accumulates in the body when we are awake, inducing drowsiness. During sleep, adenosine levels gradually decrease, allowing us to feel refreshed upon waking. The balance between adenosine and other neurotransmitters, such as acetylcholine, plays a crucial role in maintaining healthy sleep-wake cycles.
Additionally, the brain utilizes various neurotransmitters to regulate sleep and arousal states. These include histamine, norepinephrine, serotonin, hypocretin (also known as orexin), and dopamine. Histamine plays a significant role in controlling arousal and muscle tone, while norepinephrine and serotonin influence both muscle tone and arousal. Hypocretin, discovered in 1998, is particularly important in sleep regulation and has been linked to narcolepsy.
While the keto diet's restriction of carbohydrates may impact the production or function of these sleep-regulating chemicals, leading to temporary sleep disturbances, the body typically adapts to the new metabolic state over time. This adjustment period, sometimes referred to as the "keto flu," can include symptoms like headaches, fatigue, and stomach discomfort. However, as the body adjusts, sleep patterns tend to normalize, and some individuals may even experience improved sleep due to weight loss and other factors associated with the keto diet.

Sleep aids and supplements
Sleep is an essential pillar of health, and getting a good night's rest can be challenging for various reasons. Sleep aids and supplements can be a helpful tool to promote relaxation and support a healthy sleep cycle. When it comes to the keto diet and sleep, there are a few key considerations.
The keto diet, short for the ketogenic diet, is a low-carbohydrate, high-fat eating plan. This dietary approach aims to shift the body's metabolism into a state called ketosis, where fat becomes the primary energy source instead of carbohydrates. While the keto diet has gained popularity for its weight loss and potential health benefits, some individuals experience sleep disturbances, often referred to as "keto insomnia."
Keto insomnia is not a universal experience, but it is thought to be related to the strict restriction of carbohydrates. This abrupt change in diet can lead to a reduction in sleep-regulating chemicals like melatonin and adenosine, resulting in temporary sleep disruptions. However, it's important to note that not everyone on the keto diet will experience insomnia, and for those who do, sleep patterns tend to normalize as the body adapts to the new metabolic state.
To manage keto insomnia and promote better sleep while on the keto diet, consider the following strategies:
- Gradual dietary changes: Instead of abruptly eliminating carbohydrates, try gradually reducing your intake over time. This allows your body to adjust to the new diet while potentially minimizing sleep disturbances.
- Adequate hydration: Ensure you are staying properly hydrated throughout the day. Adequate hydration can support overall health and may indirectly improve sleep quality.
- Sleep-friendly practices: Incorporate sleep-hygiene practices into your routine. This includes maintaining a consistent sleep schedule, even on weekends, and getting at least 30 minutes of natural light early in the day.
- Keto-friendly sleep aids: If you need additional support, consider keto-friendly sleep aids like Som Sleep. Som Sleep is a drug-free, non-habit-forming sleep aid that combines magnesium and L-theanine to help you relax and support your natural sleep cycle. It is designed to fit within a low-carb lifestyle and can be taken regularly to promote a consistent sleep routine.
- Melatonin supplements: Melatonin is a hormone that regulates sleep and wake cycles. Keto Sleep is a melatonin supplement designed to help adults fall asleep faster and stay in ketosis overnight. It contains 5mg of melatonin and is intended to support your regular sleep routine while on a keto diet.
Remember, it is always advisable to consult your healthcare provider before starting any new diet or supplement. They can provide personalized guidance based on your health status and goals.

Sleep and exercise
The keto diet is a high-fat, moderate-protein, and low-carbohydrate diet. The standard keto diet contains 75% fat, 20% protein, and 5% carbohydrates. The keto diet can mess with your sleep early on, causing keto insomnia. This is a result of the body transitioning from a carbohydrate-burning to a fat-burning state. The body's preferred source of energy is carbohydrates, and cutting them out of your diet will likely result in tiredness until your body adjusts.
However, the keto diet can also improve sleep. A study found that adhering to this eating plan helped reduce daytime sleepiness in a group of obese patients. Another study found that ketogenic diets increase REM sleep and sleep quality in a group of children with epilepsy. A further study found that post-exercise and pre-sleep KE ingestion counteracted the exercise-induced decrease in sleep efficiency.
To improve sleep while on the keto diet, it is recommended to stay hydrated, exercise earlier in the day, and maintain a consistent sleep schedule.
