Summary

This episode reveals intermittent fasting as a potent strategy against brain degeneration, a process often starting in childhood due to poor metabolic health. Dr. Jockers explains how fasting stabilizes blood sugar, supports mitochondrial function, and activates BDNF production to promote brain repair. It also helps balance neurotransmitters and reduce neuroinflammation, offering profound long-term cognitive benefits through a simple lifestyle shift.

Episode description

In this episode, Dr. Jockers reveals the simplest yet most powerful strategy to heal and protect your brain: intermittent fasting. By stabilizing blood sugar and reducing insulin levels, fasting supports mitochondrial health, which is crucial for maintaining brain function and preventing degeneration.

You'll learn how brain degeneration isn't something that happens overnight, but rather a 30–40 year process that starts early, often in childhood. Dr. Jockers explains how poor metabolic health over time can silently damage the brain, leading to conditions like dementia and Alzheimer's.

Finally, discover how intermittent fasting not only supports brain repair but also activates powerful neuroprotective mechanisms, including the production of BDNF, a critical factor for brain regeneration. It's a simple lifestyle shift with profound long-term effects on cognitive health.

Introduction to Intermittent Fasting and Brain Health

One of the big things is when we do intermittent fasting, it brings down insulin levels and it stabilizes your blood sugar. And that's so critical because we know that brain degeneration, much of it is metabolic, meaning that when we have high insulin levels, levels and we have poor blood sugar regulation that ends up causing damage to the mitochondria and our brain is incredibly dense in mitochondria.

I just want to thank my friends over at Bioptimizers for sponsoring this podcast. And if you're over 35, your enzyme levels have already begun to decline. Enzymes are the workhorses of digestion. They break your food down into... usable macro and micronutrients. And research shows that by the time someone hits 65, their salivary and pancreatic secretions, both of which are involved in enzyme activity, have declined by as much as 50%. This decline creates

chronic indigestion, setting the stage for gut issues, yeast, and mold overgrowth, even malnutrition. That's why I'm such a big fan of enzyme supplementation. And the best enzyme I've ever found comes from my friends at BiOptim. It's called Mathzymes. Now, Mathzymes is the most complete, most potent digestive enzyme I've ever seen. or experienced with 300 to 500% more protease than most popular brands. That's crucial because protease metabolizes.

protein. And protein is the most complex macronutrient to break down. Left undigested, Protein putrefies in the gut and creates a variety of problems, from bloating to inflammation and beyond. Masszymes not only contains more protease, but it also contains 13 additional enzymes, including lipase.

for fat digestion and you can try it today risk-free by optimizers 365 day full money back guarantee is the gold standard in the industry so if you don't feel how Masszymes helps you upgrade your digestion through your food, their support team will give you a no questions asked refund for an exclusive offer.

The Rise of Brain Degeneration

Hey, today I'm talking about the most powerful daily strategy to heal your brain. You see, brain degeneration is on the rise. We have conditions like dementia, Alzheimer's, and these are growing every single day. And then people that are younger are dealing... with some of the early warning signs like poor memory, mood issues, depression, anxiety, trouble sleeping. And so there are so many people out there that are dealing with different states and stages.

of brain degeneration. You don't just wake up one day with dementia. That's literally a 30 to 40 year disease process that's taking place in your brain. And for many people, it starts in childhood. And in their teens, where people are starting to have these types of effects, where they have poor short-term memory, they are having anxiety, they have depression, they have fatigue, they feel lethargic, they're not sleeping at night.

And over time, we get more and more oxidative stress and inflammation impacting the brain. So we really need to live a lifestyle that... brings great brain health that allows our brain to function and thrive at its highest level. And I found that best, simplest strategy to apply when it comes to improving your brain function is having an intermittent fasting lifestyle where you're

Benefits of Intermittent Fasting

practicing some level of intermittent fasting. And I can talk about movement. Walking is so critical to helping drive more blood flow into the brain. And there's great research now on walking, just even walking. and how that impacts the brain. Blood sugar stabilizing diet is really, really critical. Reducing toxin exposure is super critical. But one of the simplest, easiest things you can do is eat your meals in an eight hour.

eating window, right? Or perhaps even less. And that means eating your meals, let's say starting at 10 AM and finishing at 6 PM. And there was a 2024 review article. And its title is Neuroprotective Effects of Intermittent Fasting in the Aging Brain. And this study actually went through all the effects of what happens when we start doing intermittent fasting on a regular basis and how that impacts the brain.

And so one of the big things is when we do intermittent fasting, it brings down insulin levels and it stabilizes your blood sugar. And that's so critical because we know that brain degeneration, much of it is metabolic, meaning that when we have high... high insulin levels and we have poor blood sugar regulation, that ends up causing damage to the mitochondria. And our brain is incredibly dense in mitochondria. And so as those mitochondria become damaged, we start getting more inflammation.

in the brain and that starts driving up oxidative stress, inflammation, this whole cascade. When one neuron dies, it actually spills out its contents and it damages all the cells around it. We call this neuro excitotoxicity. It's kind of like a domino effect. When one neuron dies, it actually poisons the neurons next to it.

which ends up causing all of them to go down and die like a domino effect. And so this is really, really a big thing that's taking place in many people's brains and bodies. And what happens is... we end up with this beta amyloid plaque that forms. It's almost like scar tissue in the brain.

But when we never turn off the metabolic damage, we just get more and more of this scar tissue, more and more of this plaquing. What intermittent fasting does, it brings down insulin, stabilizes blood sugar, and... When sugar goes down and insulin goes down, our body starts to increase the amount of ketones, beta-hydroxybutyrate, in the bloodstream. This is an alternative fuel source. You see, we can't get fatty acids across the blood-brain barrier.

to be used for energy. So the liver takes fatty acids, converts them into a smaller water soluble molecule, we call that a ketone. In particular, the one that we measure in the blood is called beta-hydroxybutyrate. That beta-hydroxybutyrate... gets up into the brain. where it acts as what we call an epigenetic modulator. So it actually modifies genetic pathways in the brain, and it increases something called BDNF, brain-derived neurotropic factor. BDNF is like miracle grow to the brain.

It helps strengthen the different neuronal pathways and the synapses, right? So it helps to create new proteins in the neurons. On top of that, it shuts down the inflammatory pathways. Well, I just want to interrupt this podcast for a very important public service announcement. One of the most dangerous things you may be doing for your health is cooking a healthy meal at home. I know that sounds crazy.

But here's what the science says. Most of us are unknowingly swallowing thousands of shreds of microplastic with every stir fry, egg scrambler, veggie saute. Now, where's it coming from? Your nonstick pan. In fact, one 2024... found that just a single scratch on a Teflon coated surface can release over 9,000 plastic particles into your food. and those plastic particles don't just pass through your body they build up in your arteries in your brain and they disrupt your hormones along the way

One study found that people with plastic lodged in their arteries were four and a half times more likely to suffer a heart attack or a stroke. Another found plastic particles the size of a crayon tip. inside actual brain tissue. And others now link microplastics to hormonal imbalances and fertility issues. So just like cigarette smoke in the 1950s or leaded gasoline in the 70s, microplastics

are today's invisible toxin. They're creeping into our bodies daily while the science scrambles to catch up. And it's not just old pans. Even brand new nonstick cookware can start shredding particles from the very first use. That's why I switched to the P600 ceramic cookware. It's 100% free from Teflon. pfas and plastic coatings it's made with swiss engineered ceramic and it's truly non-toxic it cooks beautifully cleans easily and most importantly it doesn't poison your food

If you're serious about reducing your toxic load, this is one upgrade I highly recommend. Right now, the P600 cookware is 50% off. And for a limited time, you can take an extra 20% off with the code SAFE20.

But so will your family. When our brain is inflamed, there's an activation of something called the neuroinflammism. So it's almost like a large alarm system where all the different cells are being activated.

Understanding Neuroinflammation

All the different glial cells and microglial cells and inflammatory compounds are being activated. When we shut that down, it quiets down inflammation. throughout the whole brain. Think about it like a, you know, if you're trying to get your radio station on and all you're getting is the feedback, it's not actually working. And then all of a sudden you.

turn that knob just a slight bit and you get perfect sound coming in. That's what happens when you turn off the neuroinflammism. Now that inflammation shuts down, now we're able to rebuild the proteins. inside of those neurons. The BDNF will help stimulate that. The beta-hydroxybutyrate helps activate something called AMPK pathway, which basically increases the amount of mitophagy. So we break down old...

damaged mitochondria, and we form new healthy mitochondria within the brain cells, within the neurons. And now those new healthy mitochondria, they're very stress resilient. So they're able to function at a high level. They're able to produce cellular energy at a high level. And that gives us better overall brain function. On top of that, when we have elevated beta-hydroxybutyrate because we're now fat burning and our insulin levels are down, we end up balancing the glutamate to GABA.

pathway in the brain you see when the brain is inflamed it over activates the excitatory neurotransmitter glutamate it's like the gas pedal of the brain And so when we're stepping on the gas too much, we end up just like driving a car, we end up getting in car accidents. We need a good balance between glutamate and GABA. Glutamate helps us think sharply and quickly, but when it's out of control, we end up with more oxidative stress and inflammation.

more anxiety, more irritability, hypervigilance, less able to focus and have control. When we have the right glutamate to GABA, GABA is like the brakes on the brain, the right ratio allows us to think sharply and quickly. but also be calm and under control, not have anxiety, not be easily triggered. And that's one of the great effects of having the right amount of insulin and also getting elevations in beta-hydroxybutyrate. Balances that glutamate to GABA pathway or ratio, I should say.

And when we get that proper ratio, the proper balance of glutamate to GABA, we're going to think sharply quickly, but also be nice and calm and relaxed, not have the anxiety. And that's super critical. So we get less inflammation.

better glutamate to GABA pathway. This is why people notice that they perform better when they're in a fasted state. In fact, people that are doing extended fasts, you may have heard this in religious circles, where people will do... extended fasts, and they'll notice that they have better creativity, better innovation, that they come up, you know, they just have better intuition and better, and they come up with a lot of different creative ideas because they have less.

of this kind of static feedback in their brain so they're able to have better overall complex thoughts, better connections between different parts of the brain. It's really, really powerful what actually happens. And doing this sort of intermittent fasting is a really great anecdote.

to the metabolic damage that so many of us have had from blood sugar imbalances and from high insulin levels. And so what do we want to do before we start fasting? I always recommend to prepare your body properly for fasting. Make sure you're doing a...

Preparing for Intermittent Fasting

high protein, blood sugar stabilizing diet. What does a blood sugar stabilizing diet look like? Well, it's going to be high in protein. eating 30 or more grams of protein in each meal. Why is that so important? Because the protein will create satiety and it will lower the insulin release for the meal. So you'll be more satiated and it will turn up fat burning.

So get the protein right. Focus on making sure you're getting at least 30 grams of protein in a meal. Add in healthy fats. Now, a lot of times your fats are going to come in your protein foods, right? So if you're eating grass-fed beef, if you're eating...

pasture-raised eggs, wild-caught seafood, you've got fats in there. But in some cases, you might need to add in some high polyphenol extra virgin olive oil, which is incredibly powerful for the brain. It has oleocanthals and hydroxytyrosols, these powerful polyphenols. that help clean up damaged brain tissue and help reduce inflammation, oxidative stress in the brain. So we can add that in there.

But make sure you got your protein, your healthy fats, and then lots of colorful fruits and vegetables. Those colorful fruits and vegetables have unique phytonutrients that support and reduce oxidative stress and support. overall healthy brain tissue. So make sure you're doing that. Make sure you're getting good movement and exercise on a regular basis and make sure you're really prioritizing good sleep, right?

Sleep is when your brain detoxifies, right? That's when you drain the brain. And so you got to make sure you're prioritizing really good sleep. I recommend trying to be in bed by 10 p.m. if at all possible, making sure you're getting out of... you know, any sort of bright lights after dark, you can wear blue light blocking glasses. You can dim all the lights in your house that will help prepare your body. It will produce more melatonin. Melatonin is this amazing.

sleep hormone, but also an antioxidant that protects your mitochondria. And so you need optimal melatonin release in order to have really good growth hormone release. And when you get the combination of melatonin and growth hormone, that's going to really help clean, heal, and repair your brain tissue and your whole body, all the different tissues in your body. It's going to help clean, heal, and repair them, all the different mitochondria so you can really function.

at your best. So intermittent fasting, incredible research behind it for supporting overall brain function and brain healing. I think it's the easiest strategy to apply, but also make sure that you're on that blood sugar stabilizing diet. getting really good movement, and making sure you're prioritizing sleep so you can have really good brain health and prevent brain degenerative conditions.
