Keto Os And Insomnia: What's The Connection?

The ketogenic or keto diet is a popular eating plan for weight loss and potential health benefits. However, some people who start the keto diet experience sleep disturbances known as keto insomnia. This phenomenon is not universal, but it is thought to be caused by the strict restriction of carbohydrates that the diet entails. Not everyone on the keto diet will experience insomnia, but for those who do, it is theorised that the immediate shift to a low-carb diet leads to a reduction in sleep-regulating chemicals like melatonin and adenosine.

Keto insomnia is caused by transitioning from a carb-burning to a fat-burning state

Keto Insomnia: Caused by Transitioning from a Carb-Burning to a Fat-Burning State

Keto insomnia is a term used to describe sleep disturbances experienced by some people when they adopt a ketogenic diet. It is important to note that not everyone on the keto diet will experience insomnia, but for those who do, it can be frustrating and disruptive to their daily routine. The good news is that keto insomnia is usually temporary and often resolves on its own as the body adjusts to the new diet.

Causes of Keto Insomnia

Keto insomnia is primarily caused by the transition from a carbohydrate-burning to a fat-burning state. This transition can lead to a reduction in sleep-regulating chemicals such as melatonin and adenosine. The body typically goes through an adjustment period, and sleep patterns tend to normalize as it adapts to using fat for fuel instead of carbohydrates. Here are some specific factors that contribute to keto insomnia:

• Low blood glucose levels: Reducing carbohydrate intake leads to lower blood sugar levels, which can disrupt sleep, especially for individuals with diabetes.
• Electrolyte imbalances: Low insulin levels due to reduced carbohydrate intake can result in electrolyte imbalances, particularly of sodium, potassium, and magnesium. These imbalances can cause muscle cramps, twitching, and headaches, further contributing to sleep disturbances.
• Digestive issues: The keto diet can initially lead to digestive issues such as diarrhea, constipation, bloating, and gastric reflux, which can impact sleep quality.
• Withdrawal symptoms: High-glycemic refined carbohydrates have similar neurological effects as addictive drugs, so transitioning off them can result in withdrawal symptoms, including insomnia.
• Increased thirst and bathroom trips: The keto diet has a diuretic effect, causing increased fluid loss through urine. This can disrupt sleep as individuals may need to wake up frequently to use the bathroom.
• Cravings and hunger: The reduction in carbohydrates can lead to cravings for sugary and high-carb foods, especially during the night. Feeling hungry can make it challenging to fall asleep and may contribute to keto insomnia.

Strategies to Manage Keto Insomnia

While keto insomnia is typically short-term, there are strategies to help manage and prevent it:

• Gradually reduce carbohydrates: Instead of cutting out carbs completely, try eliminating one type of high-carb food at a time, such as grains, sugary desserts, starchy vegetables, or fruits. This can help reduce the discomfort associated with the transition.
• Consume carbs later in the day: Eating carbohydrates in the evening can improve sleep since carbs increase brain tryptophan, which is then metabolized into serotonin and melatonin, promoting sleepiness.
• Ensure adequate electrolyte intake: Eat a variety of electrolyte-rich foods, such as broccoli, watermelon, chicken, canned tuna, and strawberries. Also, stay properly hydrated and consider using a keto-friendly electrolyte drink.
• Choose keto-friendly foods that promote sleep: Include foods rich in magnesium, tryptophan, vitamin D, and omega-3 fatty acids. Examples are almonds, spinach, chia seeds, dark chocolate, beef, poultry, cheese, eggs, tuna, pumpkin seeds, beef liver, sardines, and salmon.
• Follow a consistent sleep schedule: Stick to a specific bedtime and wake-up time, and aim for 7-9 hours of sleep each night.
• Exercise regularly but avoid intense workouts close to bedtime: Exercise can help relieve insomnia and speed up the transition to ketosis. However, avoid high-intensity workouts within 4 hours of bedtime to prevent sleep disturbances.
• Practice relaxation techniques: Incorporate relaxing activities into your bedtime routine, such as reading, listening to soft music, meditation, or taking a warm bath.
• Limit caffeine and electronic device usage before bed: Caffeine increases wakefulness, so avoid consuming it within 6 hours of bedtime. Additionally, limit screen time before bed as blue light from electronic devices suppresses melatonin production.

When to Seek Help

While keto insomnia is typically short-lived, if it persists or becomes chronic (lasting more than 3 months), it is important to consult a healthcare professional. They can help determine if there are any underlying medical conditions or other factors contributing to the insomnia and provide appropriate treatment options.

The low intake of carbohydrates on the keto diet may result in an imbalance of sleep-regulating chemicals

The ketogenic diet is a low-carbohydrate, high-fat eating plan that shifts the body's metabolism into a state called ketosis, where fat is used for energy instead of carbohydrates. While this diet is often used to improve sleep quality, some people experience "keto insomnia" during the transition from a carbohydrate-burning to a fat-burning state. This is characterised by difficulty falling asleep and staying asleep.

Additionally, the keto diet can cause a reduction in another sleep-regulating chemical, serotonin. Serotonin is a precursor to melatonin and plays an important role in regulating sleep. A 2020 study linked high-carbohydrate diets and foods containing tryptophan, melatonin, and phytonutrients to better sleep. The study suggested that these foods support the production of serotonin and melatonin, which are essential for regulating sleep.

The good news is that keto insomnia is usually temporary and tends to occur only when people first start the keto diet. As the body adapts to the new metabolic state, sleep patterns tend to normalise. However, it's important to note that the duration of keto insomnia can vary, lasting from a few days to up to four weeks.

To manage keto insomnia, there are several strategies that can be employed. These include gradually reducing carbohydrates, consuming carbs later in the day, ensuring adequate electrolyte intake, practising relaxation techniques, and maintaining a consistent sleep schedule.

Keto insomnia is a temporary problem that usually occurs within the first few days of reducing carbohydrates

The ketogenic diet is a low-carbohydrate, high-fat eating plan that shifts the body's metabolism into a state called ketosis, where fat is used as the primary energy source instead of carbohydrates. While this diet has gained popularity for weight loss and potential health benefits, some people who adopt it experience keto insomnia, which refers to sleep disturbances that occur during the initial transition phase.

The duration of keto insomnia depends on how quickly an individual adapts to the keto diet. It generally takes up to four weeks for the symptoms to subside, along with other keto flu symptoms such as headaches, fatigue, and stomach discomfort. During this time, it is important to remember that keto is a significant lifestyle change, and it will take some time to get used to running on ketones instead of glucose for energy.

There are strategies to help manage keto insomnia and ease the transition. These include gradually reducing carbohydrates, consuming carbs later in the day, ensuring adequate electrolyte intake, and following a consistent sleep schedule. It is also important to maintain good sleep hygiene practices, such as avoiding caffeine and electronic devices close to bedtime and creating a relaxing bedtime routine.

While keto insomnia can be frustrating, it is important to remember that it is usually a temporary issue. However, if insomnia persists or becomes chronic, it is recommended to consult a healthcare professional for further guidance and assessment.

Insomnia on keto can be caused by low blood glucose levels during the night

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. This shift occurs as carbohydrate intake is significantly reduced, prompting the body to break down fats into compounds called ketones.

When blood glucose levels fall below 70 mg/dL while sleeping at night, the person experiences a condition called nocturnal hypoglycemia. Nocturnal hypoglycemia can be potentially dangerous and can affect people who skip meals (especially dinner), exercise before bedtime, or drink alcohol before bedtime.

The keto diet may cause insomnia by disrupting sleep-regulating chemicals such as melatonin and adenosine. The low intake of carbohydrates on the keto diet may result in an imbalance of these chemicals, leading to difficulty falling asleep and fragmented sleep.

Additionally, when you stop eating carbohydrates, the body will first use up glycogen for energy, or the stored glucose in the body. Since glycogen binds up water, as glycogen is depleted, the body will shed excess water and electrolytes. An electrolyte imbalance can affect your body in various ways and may cause altered sleeping patterns.

The relationship between diet and sleep is complex. People who consume healthier foods tend to have better sleep quality, while those who eat more highly-processed, sugar-rich foods often have poorer sleep quality. This suggests that certain foods and eating patterns may improve sleep while others can make it difficult to fall asleep or stay asleep.

If you are experiencing insomnia or other negative side effects from adopting a keto diet, it is important to talk to your doctor. They can help you determine if the keto diet is safe for you and provide guidance on how to manage any sleep disturbances.

A lack of carbohydrates means your body is starved of L-tryptophan, which enables your body to produce melatonin

The body typically undergoes an adjustment period, and sleep patterns tend to normalise as it adapts to the new metabolic state.

A 2020 study about the relationship between diet and sleep linked high-carbohydrate diets and foods containing tryptophan, melatonin, and phytonutrients to better sleep. The exact mechanism is unknown, but researchers believe that these foods support the production of serotonin and melatonin, important hormones that help regulate sleep.

Tryptophan is an amino acid found in many foods and supplements. It is necessary for making proteins and other important molecules in the body, including serotonin and melatonin, which are essential for optimal sleep and mood.

Tryptophan can be converted into a molecule called 5-HTP (5-hydroxytryptophan), which is used to make serotonin and melatonin. Serotonin affects several organs, including the brain and intestines. In the brain specifically, it influences sleep, cognition, and mood. Melatonin is a hormone that is most notably involved in the sleep-wake cycle.

Research has shown that increasing tryptophan in the blood directly increases both serotonin and melatonin. In addition to being found naturally in the body, melatonin is a popular supplement and is found in several foods, including tomatoes, strawberries, and grapes.

Melatonin influences the sleep-wake cycle of the body. This cycle impacts many other functions, including the metabolism of nutrients and the immune system. Several studies have shown that increasing tryptophan in the diet can improve sleep by increasing melatonin.

Meats and poultry contain the most tryptophan of all foods. Lamb shoulder roast contains the most tryptophan of all meats, with one serving providing 252% of the reference daily intake. Other meats high in tryptophan include pork chops, pork tenderloin, skirt steak, ground pork, chuck steak, roasted ham, and ribeye steak.

Poultry, like chicken and turkey, are well-known for containing tryptophan. One roasted chicken leg contains 249% of the reference daily intake. Other poultry items high in tryptophan include lean chicken breast, ground turkey, roast goose, and boneless skinless chicken leg.

Dairy and egg products, like cheese, milk, and egg whites, contain tryptophan. Of these, a glass of high-fat milk contains the most, providing 80% of the reference daily intake of tryptophan. Other dairy items high in tryptophan include skim milk, 1% milk, whole milk, cottage cheese, ricotta cheese, and mozzarella cheese. One large egg also contains about 30% of the reference daily intake of tryptophan.

Sockeye salmon is the fish containing the most tryptophan, providing 203% of the reference daily intake. Other types of fish high in tryptophan include bluefin tuna, grouper, yellowfin tuna, whelk, wild-caught coho or Atlantic salmon, snapper, yellowtail, Northern pike, cod, mackerel, and tilapia.

Many nuts and seeds contain tryptophan. Those highest in it include pumpkin seeds, chia seeds, sesame seeds, hemp seeds, sunflower seeds, black walnuts, flax seeds, cashews, pistachios, and peanuts.

Oats, oat bran, and buckwheat are the highest in tryptophan, providing over 100% of the daily reference index amount. Grains that contain lower amounts of tryptophan include sorghum, teff, quinoa, and whole wheat.

Soybeans are the beans highest in tryptophan, with edamame and tofu both containing more than 100% of the daily reference index amount. Other beans high in tryptophan include navy beans, white beans, canned baked beans, kidney beans, and pinto beans.
