Intermittent Fasting and Sleep

By Ashley Jean April 13, 2023 20 mins read 128 Views

Intermittent fasting is a popular eating regimen that combines periods of fasting with periods of time when you can eat. It’s promoted to help with weight loss and improve markers of health such as blood pressure and cholesterol levels.

Some people report that intermittent fasting can affect their sleep quality. However, most of these issues disappear over a few weeks.

How Does Intermittent Fasting Affect Sleep?

Intermittent fasting can affect your sleep by altering the times that you eat, which could interfere with your body’s natural circadian rhythm. This is because eating at the wrong time can make it hard for your body to cool down for sleep.

However, this can be countered by choosing foods that help you fall asleep faster, like melatonin and human growth hormone. Both of these hormones help your body relax and release REM sleep, which is the lightest stage of sleep that helps you get more restful and refreshed in the morning.

A study published in the Journal of Physiology found that participants who used an 8:4 fasting schedule (eating only for eight hours each day, and then fasting for four hours each day) had better sleep quality than those who ate all day. They also had more time in REM sleep, which is important for mental and emotional processing.

These findings are encouraging, but more research is needed to determine the impact of intermittent fasting on sleep quality, duration, efficiency, and insomnia severity, as well as whether it may have an effect on the risk of obstructive sleep apnea. Longer-term trials with larger sample sizes will be necessary to fully elucidate these issues. For now, try experimenting with intermittent fasting as part of your health and wellness plan.

Can Intermittent Fasting Improve My Sleep Quality?

If you're trying to improve your sleep quality, incorporating intermittent fasting into your routine can be helpful. Research suggests that it can improve sleep by reinforcing your natural circadian rhythms, which manage a number of functions in your body.

These include your appetite, metabolism, and sleep-wake cycle. These rhythms are influenced by your environment and can be manipulated by the time of day and what you eat.

For example, a nighttime snack can interfere with your sleep, since it can cause you to feel hungry and may lead to poor sleep quality. You might also be more irritable, as hunger can lead to increased levels of cortisol, a stress hormone.

Another factor that could affect your sleep quality is if you eat at irregular times during your fasting periods. You can also disrupt your sleep if you eat heavy or spicy foods too close to bedtime.

Getting enough sleep is critical for your overall health, as it helps regulate hormones and brain chemicals that can improve your mood and cognitive function. You can promote healthy sleep by eating nutrient-dense foods, staying hydrated and avoiding distractions before bedtime.

What Can I Do to Improve My Sleep?

The quality of your sleep directly impacts the way you feel during the day. It can have an impact on your mood, concentration and the hormones that regulate weight and body fat.

While everyone has different needs when it comes to getting a good night's rest, there are things that you can do to improve your sleep quality. These include making sure you're going to bed at a consistent time, avoiding napping, and monitoring your caffeine intake.

Aim to get around seven hours of sleep a night. But don't force yourself to try for eight, as this could make your insomnia worse.

Avoiding caffeine and alcohol late in the day is another important tip for getting better sleep, because these can keep you awake at night.

Exercise can also have a positive impact on your sleep. It can help you fall asleep faster and stay asleep longer. However, you'll need to build a regular exercise routine that you can stick with.

Lastly, reducing your exposure to light and noise can also help you get a better night's rest. Dim the lights around your home and turn off appliances, such as TVs or computers, at least 2 to 3 hours before you want to go to sleep.

Frequently Asked Questions

How to start intermittent fasting

Getting started with intermittent fasting can seem daunting. But understanding how intermittent fasting works can make it easier to begin.

First, determine the type of fasting you would like to undertake. There are three types of intermittent fasting. The time-restricted and 16/8 methods, as well as the 5:2 diet. Time-restricted eating means that you eat only during certain hours of the day. The 16/8 method, on the other hand, requires that you eat within an 8-hour time frame and then skip the meals for the remainder of the day. The 5/2 diet has two non-consecutive days with calorie restrictions every week. Normal eating is allowed on the remaining days.

Second, make sure to stock up on nutritious foods that can be made quickly and are easy to eat when hungry. This includes nutritious proteins like eggs, fish, legumes, and pulses, healthy fats such as nuts and oils, high-fibre carbohydrates such as quinoa, buckwheat, and many fresh fruits, vegetables, to help you get your daily intake of vitamins, minerals, and other foods.

Planning your meals is just the beginning. You need to plan how you'll handle social pressures when dining out with loved ones or friends. It's important to have self-control when you live an intermittent fast life. Flexibility and adaptability are key in staying focused on your goals. Therefore, you should include sweet spot meals to increase satisfaction without compromising the progress made in recent weeks or months.

Finally, keep yourself motivated by tracking your results. This includes body weight, waistline, hips, and other pertinent areas. However, don't forget reward yourself for reaching goals.

How much weight can you lose with intermittent fasting in a single week?

You might be wondering how much weight you should lose during your weekly intermittent fasting cycle. Knowing the answer requires thoughtful consideration.

First and foremost, a balanced approach is key. To set too high goals can lead burnout and injury. Consider lifestyle factors like adequate sleep, hydration, and nutrition when planning your weight loss goals. Although counting calories is a useful tool, it should not be the only focus of your plan.

Secondly, be aware of what kind of results are realistic - losing more than 1-2 kilograms per week could put undue strain on the body, while attempting to lose less could lead to minimal or no visible results. Measurements of the body are a better way to track progress than just watching the scales change.

Finally, it is a good idea to speak with a dietitian/health professional who can offer support and guidance throughout your journey. To ensure your goal is safe, achievable, and sustainable, it's a good idea to get an objective opinion.
