29 Jan 2026
Chapter 1: What is the main topic discussed in this episode?
I spend my life studying human biology, biomarkers, and longevity, but you know what keeps me sharp?
Chapter 2: What strategies can first responders use to manage sleep disruptions?
Your questions. So I went through hundreds of comments and DMs, and I pulled the most common, most important, and frankly, the most interesting questions you've been asking. So number one, what would you recommend for first responders who work two to three 24-hour shifts per week and can't establish a consistent sleep routine.
So for people who cannot regulate their sleep and wake cycle, what you can regulate is what are your top evidence-based travel strategies for maintaining optimal health?
So my number one that very few people talk about is what evidence-based strategies do you recommend for elderly individuals, 65 or older, who need to gain weight healthy while combating age-related sarcopenia, which is muscle wasting, and maintaining metabolic health? Well, first thing you need to do is... Good morning and welcome back to the Ultimate Human Podcast.
It's Gary Brekka, and today we're doing something a little different. I spend my life studying human biology, biomarkers, and longevity, but you know what keeps me sharp? Your questions, the ones that make me stop and think, okay, how do I explain methylation or insulin response or circadian biology in a way that actually empowers people to take action?
So I went through hundreds of comments and DMs and I pulled the most common, most important, and frankly, the most interesting questions you've been asking. We're talking about first responders who can't sleep consistently, kids who need healthy snacks that aren't garbage, whether whey protein is actually processed junk, or how to approach peptides without screwing yourself up.
So here's the thing. I'm not gonna give you half answers or tell you what you think you need to hear. I'm gonna give you the science, the mechanisms, and the practical protocols because that's what you deserve. If you wanna become the ultimate human, you need to understand how your body actually works. So let's dive in.
So number one, what would you recommend for first responders who work two to three 24-hour shifts per week and can't establish a consistent sleep routine? So for people who cannot regulate their sleep and wake cycle, what you can regulate is exercise. what kind of light comes into your room at night, what kind of light comes into your eyes at night, and when you eat.
So here's what I would suggest. Make your eating schedule the same whether or not you're sleeping on a different schedule. This will actually keep your digestive pattern on the same clock. You remember, our brain works off of something called zeitburgers. Zeitburgers are things that influence your circadian cycle.
The main site burger is in the brain, but things that influence that are things like exercise, light, and eating. So you can regulate when you eat, keep that time consistent. You can regulate when you get light. So make sure that whenever you wake up, whether it's early in the morning or late in the afternoon, that you get outside and get some natural sunlight into your eyes.

Chapter 3: How can elderly individuals gain weight healthily?
And no matter what time you go to bed, make sure you invest in a cheap cotton eye mask, just a full organic cotton eye mask that you can put over your eyes and block out all the light. You'd be surprised how little light it takes to raise cortisol, which is called candle wattage, and this can actually cause your sleep pattern to be even more disrupted.
Number two, what evidence-based strategies do you recommend for elderly individuals, 65 or older, who need to gain weight healthy while combating age-related sarcopenia, which is muscle wasting, and maintaining metabolic health? Well, first thing you need to do is maintain your protein intake. As you age, you start to metabolize protein less efficiently.
One of the things that I would do is I would add essential amino acids to your diet, two to three servings a day of essential amino acids. I don't care what brand you use. I use one called Body Health, but you can use whatever brand you want, but make sure that you're not only taking in one gram of protein per kilogram of body weight, but also supplementing with the amino acids.
You see proteins in the body, break down into amino acids. And amino acids are not proteins, they're the building blocks of proteins. So very often as we age, we become deficient in protein and it makes it difficult for us to maintain muscle. The other thing that I would do is I would absolutely minimum three days a week, I would do weight training.
Now, depending on the condition that you're in, this is weight-bearing exercise. You don't have to strain yourself, but you do have to pick up heavy weight. In fact, there's a saying that if you want to live a long time, lift heavy weight.
So three things would be add all nine essential amino acids to your diet, focus on proteins and healthy fats, and make sure that weight training is a part of your routine every single week, at least three days a week. Number three, I experience migraines almost daily and conventional treatments, NSAIDs, tryptophan and preventative medications provide minimal relief.
I'm at my wit's end and I want to investigate root causes rather than just masking symptoms. Could this be related to the MTHFR gene mutation that might be affecting methylation or neurotransmitter production? Wow, that is a great question. There was a very interesting study that was published in the Wiley Journal of Headaches. I've talked about this a lot.
And what it looked at was the inverse relationship between migraine headaches and sodium. And what they found was that as migraine headaches went up, sodium levels were down. As migraine headaches went down, sodium levels were higher. This might be controversial and it might be counterintuitive to how you think about sodium. But think about this. Headaches do not come from your brain.
Your brain has no pain receptors in it. The brain is not capable of generating a pain signal. So when you think that your head hurts or your brain hurts, it doesn't, it's not generating the signal. So the question is, where is the pain coming from? Very often it's coming from the covering of your brain, which is called the dura. And the dura is fraught with pain receptors and it hates two things.

Chapter 4: What are the root causes of chronic migraines?
What I am saying is there is evidence that sodium deficiency does trigger migraines. I experience migraines almost daily, and conventional treatments, NSAIDs, triptans, preventative medications, provide minimal, if any, relief. I'm at my wit's end, and I want to investigate root causes rather than just masking symptoms.
Could this be related to my MTHFR gene mutation or affecting methylation or neurotransmitter production? You recommend exercising 30 minutes after eating to utilize glucose and prevent insulin spikes. But I struggle with this because digestion takes much longer than 30 minutes and I can't exercise with a full stomach without feeling nauseous or getting cramps.
Can you explain the physiological reasoning behind the 30 minute window? Well, actually the 30 minute window or the 45 minute window metabolic window actually doesn't exist. I actually would prefer that you exercise in a fasted state. What I do is I exercise first thing in the morning. I take all nine essential amino acids.
I mix that with mineral salt and also hydrogen water, which does not break a fast. And then I eat immediately after exercise. So if you're one of those people that gets lightheaded or shaky during exercise, try adding all nine essential amino acids and see if that is a good fix for you. If it doesn't, then I would have a protein shake and wait 30 minutes to exercise.
That's where you might be hearing that I recommended eating 30 minutes before exercise. My preference is actually to exercise fasted, but to take all nine of the essential amino acids. Number five, you recommended essential amino acids during fasting, but I'm confused about how this doesn't break a fast.
Doesn't consuming amino acids trigger an insulin response, which could halt autophagy and fat oxidation? No, amino acids being broken down or assembled breaks a fast, but all nine essential amino acids pass through the liver without being cleaved. If you don't have the nine essential amino acids, then what happens is your liver actually tries to make amino acids, and when it doesn't have them,
it converts amino acids into fat or into sugar. So these will become glucose in your bloodstream if you don't have the essential amino acids. One of the reasons why they are so bioavailable and also why they don't break a fast is because they actually don't engage the liver. The liver does not start to cleave them and turn them into sugar or to fat.
So nine essential amino acids is a great way to actually circumvent your protein intake, not as a replacement for protein, but to help you get to your amino acid equivalent without going over your macros. Number six, is whey protein powder considered a processed food that we should avoid, or does the bioavailability and amino acid profile outweigh the processing concerns?
I like hydrolyzed whey protein, but no, it's not a junk product. There actually are some very good studies showing that whey protein can lead to muscle gains, but you wanna be consuming whey protein when you are exercising, not just drinking protein shakes for the sake of drinking protein shakes. A lot of protein shakes, a lot of what you put in the protein shake also matters.

Chapter 5: How can I support my children's brain development with healthy snacks?
Number seven, what are your top evidence-based travel strategies for maintaining optimal health? Circadian rhythm, metabolic function, and supplement protocols while crossing time zones and dealing with limited food options. Wow, that is a great question. So my number one that very few people talk about is keeping your digestion on the same time.
Chapter 6: Is hormone replacement therapy safe for older women?
So I go to bed at 10 p.m. I live on the East Coast. I live in Miami. I go to bed at 10 p.m. Eastern time and I wake up usually around 6 a.m. Eastern time. So that means that my body is used to sleeping between 10 p.m. and 6 a.m. So when I travel, I don't feed my body between the hours of 10 p.m. and 6 a.m. Eastern time. Let me give you an example.
Let's say that you went to London and it's five hours ahead. That means that six o'clock in the morning when you're normally waking is now 11 a.m. in London. That's the first time that you should put solid food into your body. Now, if you're gonna be in the location for more than seven days, just go through the damage of getting onto the time zone.
But when you're traveling to places that have a different time zone for short periods of time, this could be a game changer for you just by preserving your sleeping window, not eating when your body thinks you should be sleeping. That is my best travel hack.
Number eight, what snacks do you recommend for young children that support optimal brain development, stable blood sugar, and healthy growth without processed sugars, seed oils, and artificial ingredients found in conventional kid snacks? Well, I recommend a lot of those snacks. Number one, I love beef jerky.
Really grass-fed, grass-finished beef jerky is a great way for kids to get high protein and get satiated and not get all of the garbage from highly processed foods. Number two, I like Parmesan crisps. A lot of kids like Doritos and Cheetos and other foods that have MSG and all kinds of food dyes in them.
Parmesan crisps are a high protein way to actually satisfy that craving and not give them all the junk. I also like whole foods, things like chips that are fried in grass-fed beef tallow rather than fried in seed oils. I like chips that are salted with natural sea salts rather than conventional table salt. And I also like whole fat yogurt, whole fruits, especially fruits that end in berry.
They tend to be lower on the glycemic index. So blueberries, strawberries, raspberries, blackberries, those are great for kids. They also, believe it or not, will love the crunch of cucumbers. Cold cucumbers and berries, these are things that kids like to crunch on. They also taste sweet.
Their palate changes when you feed them high sugary snacks, high glycemic snacks, and highly processed snacks. So to change that palate back, try switching to whole foods. whole-fat Greek yogurt. You can put a teaspoon of monk fruit in there, which is another way that I actually make it taste like Ben and Jerry's. Put a fistful of berries in there and even some grain-free granola.
Your kids will love it. Number nine, what are your thoughts on bison, buffalo as a protein source compared to conventional beef, grass-fed beef, or other red meats? I put those on the same plane. Grass-fed, grass-finished beef, buffalo, bison, these are all great ways to get clean protein sources. You can get leaner beef if you're actually trying to watch your weight.
