Does the Keto Diet Affect Your Sleep?

The keto diet can affect your sleep both negatively (especially at first) and positively (after a few weeks). 

However, it is essential to note that each person is unique and may respond differently to a keto diet.

Does Keto Improve Sleep? It Can — Here Are 7 Reasons Why

A better night’s rest. That sounds amazing, doesn’t it? 

Let’s look at seven reasons why keto can help you have a blissful night of sleep.

#1: The Promotion of Adenosine Activity in the Body

Researchers find that ketogenic diets affect adenosine, a brain chemical that regulates sleep. 

Throughout the day, adenosine builds up in the body. Over time, it reduces our alertness and wakefulness as the day progresses, promoting deeper sleep at night. 

A ketogenic diet promotes adenosine activity in the body, thereby relaxing the nervous system.

#2: Reduction of Pain and Inflammation

Ketogenic diets reduce inflammatory markers due to their healthy fats and lack of sugar. Compared to a low-fat diet, keto is much better at reducing inflammation

When sugar and processed foods are removed from the diet, inflammation and pain in the body and joints are reduced, resulting in a better night’s sleep.

#3: Lower Body Temperature

To fall asleep more easily, it is beneficial to have a cooler body temperature before bedtime.

On a keto diet, you are decreasing the number of carbs you eat. Since eating carbs raises our body temperature, indulging in them could negatively affect sleep. 

Removing carbs and increasing protein can positively impact sleep quality. Get rid of those carbs, maintain a lower body temperature, and have sweeter dreams.

#4: Less Time Required During Sleep To ‘Detox’ and ‘Repair’

When your body is trying to detox from unhealthy foods, it has difficulty repairing itself. This happens while you sleep, so your body works hard, even though you are in dreamland. 

It is clear that when inflammation persists, it makes it harder for things to heal. It is essential to improve healing over time to eat a diet low in sugars and carbs and high in anti-inflammatory foods, like those found on a ketogenic diet.

#5: Weight Loss

Generally, getting to a healthy weight can improve sleep. 

Since the keto diet can help with weight loss, it can be a useful tool for improving your sleep 

#6: Cortisol Regulation

Cortisol levels can be significantly affected by sugar. 

In the body, cortisol plays an essential role as a stress hormone. Removing sugary foods from your diet can help stabilize stress hormones (like cortisol) throughout the day, allowing you to sleep better at night. 

#7: Reduced Daytime Sleepiness

The more energy you have during the day, the easier it is to fall asleep at night. According to a recent study, patients who adhered to the keto diet reduced daytime sleepiness.

Additionally, if you have more energy during the day, you’re less likely to reach for a cup of coffee in the afternoon to stay awake.

Does Keto Negatively Affect Sleep? It Can, Especially at First — Here Are 3 Reasons Why

Tossing and turning all night? Tired of counting sheep? Don’t worry. This can be normal at the beginning of implementing a keto diet. 

Let’s take a closer look at three reasons you may have difficulty sleeping on keto. 

#1: Creating a Metabolic Change Isn’t Easy

In the long run, healthy weight loss and weight maintenance will benefit your sleep. Sleep disorders such as obstructive sleep apnea will be less likely to occur, and as a result, you’ll sleep more comfortably and wake up feeling more energized. 

However, losing weight without a sound, consistent sleep routine is not a smart move. 

The key is to identify the eating habits that help you: 

  • Lose excess weight
  • Maintain a healthy weight; and 
  • Sleep well

This could take some time, but it will be worth it in the long run.

#2: Lower L-tryptophan and Seratonin Levels

Generally, carbohydrates are the body’s primary energy source. They provide a constant supply of glucose and improve the entry of the amino acid L-tryptophan into the brain.

In addition to its role in the production of serotonin, L-tryptophan contributes to better sleep and well-being by calming the body. During sleep, melatonin, the sleep hormone, is converted from serotonin.

A ketogenic diet lacks carbs, so it doesn’t contain dietary L-tryptophan, which can lead to low serotonin and melatonin levels. What can you do? Ensure you’re eating enough of these minerals by NOT limiting your protein intake.

#3: Hunger Pangs

When adjusting to the keto diet you may feel hungry, especially at night, which makes it difficult to sleep.

If hunger strikes during the night, the brain becomes mentally alert, making it harder to get a full night’s sleep.



Tips for Navigating From ‘Keto Insomnia’ to Restorative Sleep

Save the Carbs You Do Eat for the End of the Day

Your keto diet allows you a few carbs, so savor them! It is best to enjoy these delicious indulgences later in the day rather than first thing in the morning.

Remember those hunger pangs we mentioned earlier? You may sleep better and wake up less hungry if you schedule your carb intake about four hours before bedtime. When you eat carbs for dinner, you give your body time to make the hormones that will allow you to sleep better at night.

Incorporate Sleep-Inducing Foods

As well as saving your carbs for the evening, you can also eat foods that induce sleep. 

These foods contain significant amounts of melatonin, a hormone that helps you sleep: 

  • Eggs
  • Fish 
  • Oats; and
  • Bananas

Bananas aren’t just beneficial for melatonin. They are unique because they’re also rich in L-tryptophan and magnesium. Magnesium is a natural muscle relaxant that can assist the body and mind in winding down before bedtime.

If you want to add more magnesium to your diet, you can add the following: 

  • Avocados
  • Nuts; and
  • Tofu

Oats are another excellent choice to add to your diet. As well as promoting gut health, oats also contain essential prebiotics, which helps you sleep better.



Get Your Day Going With Exercise

To lose weight, most people combine diet and exercise. 

You may be considering a new exercise routine if you have decided to try the keto diet. It’s a great idea, especially if you’re concerned about sleep quality. 

Exercising in the morning can make you feel tired at night, allowing you to sleep longer and deeper. A physical activity program may also help you combat those pesky mood swings associated with the “keto flu.” 

Additionally, avoid exercising too close to bedtime, as this may cause an unwanted surge of energy. Please note, you should eat your allotted carbohydrates and drink plenty of water when you combine keto and moderate to intense exercise.

Keep Your Electrolytes Balanced

The keto diet causes many people to lose electrolytes. 

As part of their role in the body, these minerals: 

  • Support hydration
  • Reduce the symptoms of insomnia
  • Prevent leg cramps
  • Promote energy; and 
  • Promote healthy cells

An Epsom salt bath before bed can improve sleep and boost electrolytes simultaneously. Magnesium is abundant in this salt, which your body absorbs directly through your skin during your soothing, warm soak. Add a few drops of chamomile essential oil to promote relaxation and sleep. 

Bone broth is popular on keto because not only does it help you maintain healthy electrolyte levels, but it also contains an amino acid called glycine, which enables you to sleep better.
