11 Powerful Ways Intermittent Fasting Strengthens Your Brain

Intermittent fasting benefits for the brain

Intermittent fasting benefits for the brainBreakfast is the most important meal of the day, right? Well, when I ‘break my fast’ after not eating for 16-20 hours, it is! We’ve been told that small meals spread throughout the day are the key to good health, but new research is showing that this may not always be the case.

Intermittent fasting is more than just a trend; there is mounting evidence showing that it can help our bodies in ways that are almost unimaginable. Not only does it often prevent us from overeating, but it also sets off an avalanche of genetic and molecular changes that can help our brains perform optimally and decrease aging.

It may sound too good to be true, so let’s get into what scientists have found.

Intermittent fasting can…

  1. Reverse metabolic syndrome and all of its negative consequences.
  2. Increase brain strength and your ability to learn by boosting synaptic plasticity.
  3. Save your brain from the harm of oxidative damage from free radicals.
  4. Grow neurons and protect them by bumping up levels of neurotrophic factors.
  5. Decrease inflammation and avoid chronic diseases that come with it.
  6. Increase metabolism by growing brown fat (yes, there is a good kind of fat).
  7. Activate proteins that clean up your brain and again protect it from harm.
  8. Put you into ketosis and boost white fat metabolism.
  9. Help your mitochondria use energy more efficiently.
  10. Increase the body’s production of NAD, an essential molecule for metabolism and longevity.
  11. Boost stem cell production to provide more neuronal growth and recover from brain injuries.

What is intermittent fasting?

Intermittent fasting doesn’t mean that you are starving yourself, but rather it means that you are going approximately 14-48 hours without eating. Most people who utilize this tactic in everyday life will simply restrict their eating to a 4-10 hour window every day. The goal isn’t to limit calories, but this will most often naturally occur the shorter your eating window is.

For me, I will abstain from eating until I get home from work. This means I only eat from 4:00 PM to about 8:30 PM. Aside from the plethora of health benefits, I also save a lot of time because I don’t have to make breakfast or lunch and then take a half hour break to eat lunch. Then, when I get home, I have a large meal and snack for about 4 hours.

How Intermittent Fasting Benefits The Brain

When doing research on this topic, I was expecting it to be difficult to find good studies. Instead, I was inundated with what science has found. Intermittent fasting has a massive amount of research showing that it is beneficial for the whole body, but for now, let’s focus on the brain.

  1. Intermittent Fasting Can Reverse Metabolic Syndrome By Increasing Insulin Sensitivity

Metabolic syndrome is possibly the source of many chronic diseases that plague modern society. In short, it is a conglomerate of the many consequences of leading an unhealthy lifestyle, including abdominal obesity, poor cholesterol, blood lipids in the unhealthy range, high blood pressure and high fasting glucose [1].

“The Metabolic Syndrome has been called a global epidemic by the World Health Organization and is considered a major public health problem, with 34% of Americans over the age of 20 estimated to be affected”

Intermittent Fasting Can Reverse Metabolic SyndromeIt is typically defined as a cluster of risk factors associated with Type II Diabetes and cardiovascular disease which we also know from a previous article is associated with dementia. Aside from the risk of age-related disease, general cognitive dysfunction occurs as well [1].

Essentially, people with Metabolic Syndrome have brains that start to function sub-optimally, their risk for stroke goes up, brain structure changes and energy depletion is seen. This is all thought to stem from a reduction in insulin sensitivity which is better known as insulin resistance [6].

Metabolic Syndrome has also been associated with a loss of cognitive power including lower information processing speed, shortened attention span and decreased ability to achieve goals.

 [Find an in-depth explanation of insulin resistance and how it harms the brain here.]

How We Get Metabolic Syndrome

In a nutshell, when we eat too many processed carbohydrates, our blood becomes flooded with glucose and the pancreas has to pump out copious amounts of insulin to clear it out and store it in cells. As time goes on and this abuse continues, our cells begin to lose the ability to grab onto insulin and take in the glucose, hence the name insulin resistance.

This has dire consequences for the entire body, but the brain specifically loses the ability to get enough energy and also becomes inflamed. There is also an increase in oxidative damage which leads to accelerated age-related decline.

“Metabolic Syndrome has been linked to deficits in memory, visuospatial abilities, executive functioning, processing speed, and overall intellectual functioning”

This is a lot of information so let’s summarize the key points about Metabolic Syndrome:

  • Metabolic Syndrome is a tremendous health crisis that is likely caused by living an unhealthy lifestyle.
  • The underlying cause of the ‘outside’ symptoms is likely insulin resistance.
  • Insulin resistance doesn’t allow the brain to get enough energy, causes inflammation and increases oxidative damage, among other ailments.
  • This condition is associated with cognitive dysfunction and cognitive decline in general.

Intermittent Fasting Comes To Save The Day

Now, in comes intermittent fasting to save the day. When we are in a fasted state, the body isn’t overflowing with glucose because we aren’t eating. This means that when we are fasting, glucose doesn’t have to be shuttled around so blood glucose levels AND insulin levels both go down [2].

This gives our cells a break from the constant bombardment from insulin which results in reduced insulin resistance when done for extended periods of time. Along with this comes a decrease in age-related brain diseases such as Alzheimer’s, Parkinson’s, and Huntington’s [3,4].

Put another way, the research is clear in saying that intermittent fasting may be a natural cure for Metabolic Syndrome, one of the most widespread health conditions of our time. The implications for day-to-day health and longevity are massive.

In one study ” Overweight subjects maintained for 6 months on a twice-weekly intermittent fasting diet in which they consumed only 500–600 calories on the fasting days, lost abdominal fat, displayed improved insulin sensitivity, and reduced blood pressure.” [4]

Furthermore, another study showed that overweight subjects who were put on intermittent fasting for one year had better working memory, improved mood, and higher cognitive processing speed when compared to their baseline test [6].

It seems that intermittent fasting was able to reverse some of the cognitive dysfunction caused by Metabolic Syndrome. The brain can get the energy it needs, lower inflammation, and reduce oxidative damage.

The benefits of intermittent fasting don’t end here. Let’s see what else it can do for the brain.

  1. Intermittent Fasting Helps You Learn Faster

Intermittent fasting increases synaptic plasticityIt has been shown in multiple studies that intermittent fasting increases synaptic plasticity  [4,5]. Synaptic plasticity is essentially the brain’s ability to change. It allows the brain to grow stronger, learn new skills, and keep memories.

An example of synaptic plasticity is when blind people develop a stronger sense of smell to compensate for their lack of eye site. Other more common examples would be the ability to learn a new language or anything that is kept in memory.

 

  1. Use Intermittent Fasting to Make Your Neurons More Resilient

Another part of the intermittent fasting story is that is has been shown to keep the brain safe from harmful attacks by free radicals. Free radicals like reactive oxygen species occur through natural processes in our bodies and luckily the body is able to clean up almost all of them.

The key word in the last sentence is ‘almost’. The ones that escape the body’s natural defenses go on to do harm to cells including brain cells which causes aging. Living an unhealthy lifestyle can increase the amount of free radicals, but by incorporating tactics like intermittent fasting into a healthy lifestyle, you can also reduce oxidative stress and decrease your rate of aging [2].

This all happens because intermittent fasting puts a small amount of stress on neurons and other cells of the brain. Not enough to do damage, but enough to strengthen the cells’ mechanism of protecting themselves [2].

One interesting example of this was among asthmatic study participants. After doing intermittent fasting for just 4 weeks, oxidative damage and inflammation went down as well as their symptoms of asthma [5].

  1. Neurotrophic Factors: A Molecular Juggernaut

Another major change to the brain when undergoing intermittent fasting is that brain-derived neurotrophic factors are released in response to the slight stress. Neurotrophic factors are a large class of molecules and the word itself simply means brain and nervous growth [2].

intermittent fasting boosts neuronsNeurotrophic factors are important because they can stimulate new neuronal growth. There aren’t many ways that this can be done and more neuronal growth means more brain power and slower aging. I don’t know about you, but these are both things that I’m looking for.

In addition to growing new neurons, neurotrophic factors also protect neurons from outside damage and have the ability to repair damaged neurons. One other duty of neurotrophic factors is to optimize energy intake and expenditure of the brain [5]. In other words, they give your brain the juice it needs to keep you smart, focused, and aging well.

“intermittent fasting modifies brain neurochemistry and neuronal network activity in ways that optimize brain function”

  1. Get a Huge Decrease in Inflammation

Many studies have shown that intermittent fasting reduces inflammation, especially in the brain [4,5]. This is important because many chronic diseases of the body and the brain may have inflammation at their roots. If the disease isn’t caused by inflammation, it will at least be made worse.

In one study done on overweight men and women, intermittent fasting led to improved mood, lower oxidative stress, and lower inflammation [4]. All of these changes are bound to have a profound impact on their quality of life.

  1. Want to Boost Metabolism?

We normally think of fat in a negative way, but brown fat is actually very healthy as opposed to white fat. It has been shown that intermittent fasting boosts brown fat which is another way the body regulates metabolism. Brown fat allows our bodies to utilize energy more efficiently which is good news for the brain.

Commonly brown fat is only formed through cold exposure. Instead of sitting in an ice bath for an hour, you can just fast instead! In my opinion, that is a much better option.

  1. Powerful Proteins Activated by Intermittent Fasting

In addition to activating neurotrophic factors, intermittent fasting has been shown to activate heat shock proteins and glucose-regulated proteins [2]. These are like your body’s street sweepers. They clean up misfolded proteins and make sure that other proteins are folding properly.

This is important because misfolded proteins cause harm to cells and are typical in the brain-plaques of diseases like Alzheimer’s. Misfolded proteins are also present in some forms of brain cancer, so getting rid of them is crucial. So, in the end, this is another way that intermittent fasting helps out our neurons.

Like attaining brown fat, the most common way to activate these proteins is through a temperature extreme, except the heat-shock proteins require (you guessed it) heat rather than cold. Now you have another method in your molecular activation toolbelt.

  1. Intermittent Fasting Results in Ketosis and Fat Metabolism

intermittent fasting helps fat lossWhen we are eating a diet that contains carbs, our bodies utilize glucose as it’s main fuel source. However, through dietary changes like eating a high-fat diet with low carbs or through intermittent fasting, the body no longer has any glucose to use and turns to fat for energy.

This change in metabolism is called ketosis. Many studies have shown that this switch results in fat loss [5], which leads to less insulin resistance and alleviates the problems of metabolic syndrome like we talked about earlier even more [2].

Intermittent fasting and ketosis are both used in patients with epilepsy to prevent seizures and also to protect neurons from damage [2]. It has also been shown in these cases that this metabolic switch can protect brain cells from outside harm.

  1. Use Energy More Efficiently

While we are on the topic of how our body uses energy, studies also show that intermittent fasting forces the brain to use energy more efficiently [2]. This makes complete sense because although we consciously know we will eat after a given amount of time, the underlying protocols held by our body still act as if we don’t have any more fuel and need to use the rest of our energy more efficiently.

This is specifically shown in our mitochondria, the powerhouse of the cell. Most of our energy comes from these little machines in our cells called and intermittent fasting has been shown to help them function, survive, and grow [5,6]. In the brain, this is crucial for optimal function and longevity.

  1. Fasting Increases NAD

Intermittent fasting helps mitochondria use energyNAD, otherwise known as nicotinamide adenine dinucleotide, is a molecule that is essential for energy utilization in mitochondria. This magical molecule is increased by intermittent fasting as well [7]. So, not only does intermittent fasting make mitochondria grow faster and survive longer, but it also increases molecules that help them function.

People take extreme measures to boost NAD, even to the point of paying hundreds of dollars to have it injected via IV. With intermittent fasting, you can boost your own supply naturally for free!

  1. Keep Those Stem-Cells Growing

Stem cell research might be the next revolutionary step in modern medicine. Throughout the body and brain, we have many different types of cells, and stem cells are a special type that can grow into any type.

Intermittent fasting increases stem-cells which are thought to be another reason why we see increased neuronal growth and faster recovery from brain injuries [4,6].

How to Start Intermittent Fasting

drinking coffee while intermittent fastingThe best part about all of this is that intermittent fasting is fairly simple and straightforward. You just restrict your eating (of hopefully healthy, nutritious foods) to 4-10 hours every day, or sporadically go up to 48 hours without eating. The experts say that you don’t even really need to decrease overall calories, just regulate the timing of the calories [5].

I still allow myself to drink calorie-free beverages like coffee and tea. Sometimes I’ll even add some cinnamon to my coffee or drink a spiced tea to give myself some flavor.

“IF can be achieved in with a minimal decrease in overall calorie intake if the refeeding period in which subjects overeat is considered. Thus, fasting cycles provide a much more feasible strategy to achieve the beneficial effects”

The hardest part and maybe the downfall of intermittent fasting is that it requires a large amount of discipline. An amount of discipline that needs to be cultivated by the ‘hangry’ mobs out there in order for it to be successful.

When you have food at your fingertips and feel your stomach begging for you to hit the snacks, you must overcome the urge and know that you are doing your brain (and the rest of your body) a huge favor.

Get Your Fasting Habits Into Rhythm

For most people, this urge comes from your body being in a rhythm of eating frequently throughout the day [8]. When your body is expecting food and you neglect it, the hunger pangs will start, and they might be ferocious. However, research has shown that your body will readjust over a period of about 3-6 weeks to your new eating schedule [5].

This isn’t to say that you won’t still get hungry after your body has adapted. Once I get close to my eating window, I sure do, but the hunger is far less than when I first started. As a long-term diet, however, intermittent fasting has been shown to be easier to maintain than simply reducing overall calories every day [8].

“there is great potential for lifestyles that incorporate intermittent fasting during adult life to promote optimal health and reduce the risk of many chronic diseases, particularly for those who are overweight and sedentary”

Something You Should Try

In the end, intermittent fasting is a natural approach that can drastically change the lives of many people if implemented in a healthy way. Science shows that the effect it has on the brain and health in general is undeniable.

Start off just by not eating 2 hours before and after bed and work your way up. Ease your body into it. The longer your fast goes, the stronger the effects become. You get to decide how far you want to go. Just remember to refeed your body completely with nutritious foods afterward.

With all of this said, if you have any medical conditions that may be affected by this diet, contact your primary health practitioner before starting. While the diet may help children and the very old, there has not been nearly as much research done in these areas so proceed with caution.

So, give it a try, stay disciplined, stay healthy, and change your life.

Two Super Supplements To Combat Reactive Oxygen Species In The Brain

turmeric and resveratrol for brain health

After a quick search for ‘brain power’ or ‘brain health’ on Google or social media, you’ll likely come across many posts with so-called ‘brain superfoods’. Common food such as avocados, various nuts, chia seeds, and maybe even sardines will litter your search results

curcumin and resveratrol aid the brain's longevityWhile these are all great and should be a part of a balanced diet, I am always personally more interested in digging deeper to find less known foods and supplements that still yield powerful benefits for brain health that are also backed by science.

I stumbled upon a recent study by Davery and Agrawal that fit this description perfectly. It explained how beneficial curcumin (from turmeric root—Curcuma longa) and resveratrol (from grapes, wine, and nuts) are for brain health, function and longevity. It turns out that they are quite the molecular superheroes when it comes to fighting one of the brain’s biggest villains, reactive oxygen species.

Reactive Oxygen Species

Now, before I go into what they found, it would be useful (and necessary) to learn about reactive oxygen species (ROS), where they come from, and why they are harmful. In short, reactive oxygen species are unstable molecules that contain an oxygen.

ROS harm cells once past defensesInside of our bodies, ROS are always being made through metabolism and breathing, but luckily our natural antioxidants mainly take care of them [1]. However, if we have too much inflammation in the body such as that caused by eating an unhealthy diet, we may have an excess of ROS which can allow them to enter our cells.

Once past the cell’s natural defenses, they wreak havoc on the inside. The ROS then cause “oxidative stress” which can damage our DNA, fats, proteins, and can contribute to brain diseases such as Alzheimer’s, Parkinson’s, and multiple forms of cancer. While ROS do serve a few purposes inside the body, it is important that they are kept in check through diet and, as this study points out, supplements.

Protecting Our Brains From Reactive Oxygen Species

Curcumin and resveratrol are two old dogs when it comes to the supplement world. People and cultures have been consuming them for ages, although they mainly have just been a part of their diet. Recently, however, I have started to see them pop up more and more on the shelves of nutrition shops and health stores.

Despite this, most users don’t typically think of brain health when consuming the capsules. Though the anti-aging and anti-inflammation properties of the two are backed by science, new research shows that curcumin and resveratrol should also be considered brain supplements as well. Here’s why.

Curcumin and Resveratrol for the Brain

The researchers I mentioned above wanted to determine specifically how curcumin and resveratrol protected brain cells from ROS, the nasty enemy of health and the brain. What they did was fairly straightforward: expose brain cells to ROS and see if they could be rescued by the two supplements.

supplements for brain power and longevityMore specifically, the cells used by the researchers were called astrocytes, the most abundant cells in the central nervous system. They play an important role in how well the body and mind function while simultaneously holding some control of inflammation in the brain. While all cells are important, they chose arguably the MOST important to do their experiments on.

When placed under oxidative stress from excess ROS, astrocytes can die which is detrimental to brain health, but alternatively, removing oxidative stress can make them live longer and improve longevity. This is because astrocytes don’t have the same antioxidants that are seen in many other cells.

Now, on to their results! They found that both resveratrol and curcumin made the astrocytes live significantly longer than the control without them. Interestingly, curcumin was more effective short-term (4 hours after administration) and resveratrol was more effective after a longer time-period (24 hours after administration).

In addition to this, curcumin was able to reduce inflammation in the brain cells caused by oxidative damage, while resveratrol was not. Curcumin has also been shown to repair some of the damage done by inflammation and oxidative stress as well. These results are important because it shows that these two supplements can somewhat make up for the brain cell’s lack of defense against ROS by protecting them.

“Curcumin and Resveratrol both protected astrocytes from oxidative stress thus potentially using them for treating various neurodegenerative diseases.”

The Takeaway

Based on the results, the researchers concluded that it might be a good idea to supplement with both curcumin and resveratrol. While I agree with this, if you have a limited budget, go with just turmeric extract as it is cheaper, and research suggests it is more broadly applicable to other parts of the body.

As a side note, if you want these same benefits, you will likely need to invest in a supplement (like the ones listed below) instead of just incorporating turmeric into your diet as the root powder won’t have the specific compounds in a high enough concentration to be helpful. So, give one a try to keep your brain happy and healthy!

Listen Up! Your Hearing May Be At Risk

guy with headphones

I wake up, put on my wireless headphones and listen to a podcast on my way to the gym. During my workout, I listen to hip-hop or rap until it comes time to stretch and cool down when I then switch back to a podcast. Before I start working on my laptop, I switch to an instrumental playlist to drown out my surroundings, keep me focused and slightly entertained. When it’s time to cook or do chores around the house, maybe I’ll listen to an audiobook. Alright, time to get back to work and flip on the instrumentals. This process goes on all day for many days of the week. Despite it being so chiseled into my routine, there has always been a voice in the back of my head saying, “are you sure that listening to headphones 8+ hours a day isn’t bad for your hearing?” This voice was always silenced because I enjoyed the benefits of what I listened to all day.headphones

However, if I am truly concerned about the longevity of myself and others, it would be a disservice to not investigate the research that has been done so that we all can make a more informed decision about our headphone habits and listening in general.

What is hearing and how is it harmed by noise?

Our ears are amazing tools that we often take for granted. When a noise is made, a sound wave is emitted through a difference in air pressure. When this wave makes it to our ears, it is amplified by our eardrums and a couple tiny bones. This amplification then hits tiny hair cells (stereocilia) which vibrate and create a nerve impulse that is translated by our brains into the sounds we hear [2]. This is an astounding process that many (at least myself) don’t think of on a day to day basis.

ear diagramThese tiny hair cells are not indestructible and that is why people get hearing loss. When we are subjected loud noises for even a short period of time, these cells can become damaged and possibly die. The result this cell death is that our ability to hear degrades. For most of us, this is a prolonged process that happens with age, but it can be sped up if we are consistently in a noisy environment without hearing protection. Even more, we can speed up the process by subjecting ourselves to unnecessary loud noises.

It is fairly intuitive that going to a concert, club, or listening to loud music can damage our hearing. Despite this, studies show that most people feel their ears are invincible to loud noises and would rather not impose a high music limit on their personal listening habits [1]. This is understandable; when you’re young, hearing loss doesn’t really seem like an issue. That is, until later in life when you have to yell “WHAT?!” every time someone speaks to you.

“Although they appeared to be generally aware of the risks of exposure to loud music, they expressed low personal vulnerability to music-induced hearing loss”

Let’s talk about decibels

Most often, the decibel (dB) scale is what is used when we talk about how “loud” something is. Since everyone’s hearing is different, the goal of the scale is to reduce the consequent subjectivity of what is considered to be loud. On the scale, 0 is the quietest noise the general person with no hearing loss can notice and every increase of 10 doubles the intensity of the sound. So, 20 dB is twice as loud as 10dB, and so forth.

earsHow do decibels affect our hearing you may ask? Well, the CDC recommends that 85dB should not be listened to for more than eight hours. Also, the limit for 95dB is 47 minutes and 105dB is just 5 minutes. This may not mean much right away, so let’s put it in perspective. Most cell phones and mp3 players allow a max headphone volume between 91-121 dB [3]. This means that depending on your device, going over 80% might be harmful to your ears if you listen for a long period of time. Luckily for me, I almost never go above 50% on my Samsung S7, so according to this, I should be safe. Although, during my workout, I may push it above 75% so I will have to watch out for that. I recommend you do the same.

Aside from my recommendation, the rest of you are likely already somewhat similar in your listening habits. A study found that on average, people listen at about 72 dB which does not cause damage. However, if you’re one of those people that have music loud enough so that everyone you walk past knows exactly what song you are listening to, maybe it’s time to reconsider.

Beyond headphones

While on the topic of hearing loss, the same voice telling me that headphones are bad for my ears also chimes in whenever I attend concerts. The data on concerts is a bit more alarming. One study found that there are significant amounts of hearing loss among college students who regularly attend concerts [3]. You know that feeling after a concert when you can’t really hear for an hour or so afterward? Ya, me too, and that means those little hair cells in the back of your ear are struggling. This is because the average club music is about 95dB and concerts are about 105dB. From the CDC information, we know that 105dB is only safe for 5 minutes! Despite this, most concerts last anywhere from 1.5-3 hours. That can be a lot of damage depending on where you are standing.

concertI think all of us can be a bit more responsible when it comes to our hearing. And we better start right away, because hearing loss can really hinder older adults socially and economically. Researchers found that severity of hearing loss was statistically correlated with reduced quality of life as we age [7].

“Severity of hearing loss was significantly associated with decreased function in both the Mental Component Summary score and the Physical Component Summary score”

If you want to get a check up on your hearing, head over to your local Otolaryngologist (ear, nose and throat doctor). If that is too much of a hassle, there are a couple really good hearing apps that can be put to use if you have a smartphone. The app “uHear” for IOS was shown to be very accurate even in a clinical setting [6]. There hasn’t been any research done on apps for Android, but “Hearing Test” by e-audiologia.pl seemed to be an easy and straightforward option when I used it.

The takeaway

The research in this area is nowhere near complete, but for now, it is safe to continue listening through headphones. Besides, there are massive benefits that many get such as increased focus during work or studying, extra intensity during a workout, or simply acquiring knowledge through books or podcasts. With that being said, be careful with your ears. They are hugely important when it comes to our quality of life, and when they go out, there is no getting them back.
