Speaker 1 (00:00):
Now here's a highlight from coast to coast AM on iHeartRadio.

Speaker 2 (00:05):
Man, welcome back, George Norrie longwo Doctor Brennan Spiegel, Doctor Spiegel.
Is it gravity that makes people feel better?

Speaker 3 (00:14):
Well, yeah, I mean we feel better when we use
gravity to our advantage. You know, gravity isn't just a pull,
It's also a push. That's what Einstein told us about relativity.
It's just as much pushing up into us as it's
pulling us down. And so if we think about it
that way, we can start to use gravity's influence to

(00:35):
live a better life, to actually strengthen our body. So yeah,
for sure it can make us feel better.

Speaker 2 (00:43):
What are some of the techniques involved to make gravity
enhance yourself?

Speaker 3 (00:49):
Well, right now as I'm talking to you, I am
wearing a weighted vest. I wear about sixty pounds on
my body when I'm at work, and I wears yep,
I wear a twenty pounds on each ankle and twenty
pounds on my vests. And I worked up to that.
But the way I look at it, just like a
baseball player weights, you know, his bat down before he

(01:12):
goes up to swing, because he gets a lot stronger
with the weight on the that donut on his bat,
same thing here. If I can wear this weighted vest
on me, I'm simulating life on a larger planet with
a greater gravitational pull. So when I take that off,
life becomes much easier. I can bend down easily, you know,

(01:34):
go to the grocery store, pick up my kids, whatever
it is I need to do. It's a lot easier
if you've been practicing life on a larger planet. So
that's just one of many examples of how we can
think about changing our relationship to gravity.

Speaker 2 (01:48):
How often do you weigh yourself down?

Speaker 3 (01:51):
I do it every day when I'm at work. So
at work, I have a standing desk. Now I happen
to work in an office, but you don't have to
beat an office, so you can just go about your
day chores, daily routines, wearing a weighted vest. Can wear
it under your clothes, low profile. I do it every
day for most of the day, and then I take
it off and I head home.

Speaker 2 (02:12):
When you take the weights off, do you feel like
you're gonna float away? Yeah?

Speaker 3 (02:16):
Exactly. I feel buoyant, you know, like anti gravity. My
body's been trained to experience so much pole that the
Earth's gravity feels a lot lighter, like it's less than
one G. If you've been practicing with more than one G.

Speaker 2 (02:30):
Now by feeling lighter, what does that do to you?

Speaker 3 (02:35):
Well, there's some evidence that that improves both physical and
mental health, so you feel more buoyant. We know that
when we stand up, and we stand up straight with
a straight back, it literally can elevate your mood. And
I mean literally elevate. Just think about the word elevate.
Elevate means up and that's the opposite of descend. So

(02:58):
we can elevate our mind and body by basically kind
of fighting gravity in this way of thinking about it.

Speaker 2 (03:07):
What do your colleagues or what does science say about
your book? Poll?

Speaker 3 (03:12):
Well, the book is full of science. So one of
the important things to me was that before I wrote
this book, I had to feel comfortable that the evidence
was there. So there's over three hundred articles in the
book alone that I cite, and there's many more beyond that.
And as I started writing this book, I started hearing
from researchers all across the world, including some at space

(03:34):
agencies here in the US, who said, you know, we've
been thinking a lot about this for a long time,
and we haven't really seen a single book on this topic.
So I did a lot of research before I wrote
this book.

Speaker 2 (03:45):
Have you ever been on a roller coaster? Brennan?

Speaker 1 (03:47):
You bet I have?

Speaker 2 (03:48):
Yeah, What is that funny feeling we have in our gut?

Speaker 3 (03:52):
I mean, that's a great question, because what is it
about falling on a roller coaster that gives you those butterflies?

Speaker 2 (04:00):
Like?

Speaker 1 (04:00):
What is that?

Speaker 3 (04:01):
Why is a gravity challenge like falling on a roller
coaster make you feel that way? And by the way,
it's the same feeling that some people get when they're
falling in love, right, these butterflies, that's a metaphorical fall huh.
So you know, as a GI doctor, the stomach doctor,
I spend a lot of time thinking about this because

(04:21):
I see a lot of patients who have those feelings
in their belly all the time, and it really bothers them.
It's like they're always falling on a roller coaster. And
those are the same people who won't ride a roller
coaster because it just makes their belly ignite. It's as
if we have a G four sixcelerometer in our gut
telling you that you're about to die. I mean, really,
that's why we ride roller coasters. Right, We're practicing our death,

(04:44):
but we know we're going to survive. Intellectually, you know
you're going to get off that roller coaster, but your
brain is like, I never signed up for a twenty
story drop. Right. Every part of your DNA is etched
with fear, and so your gut life and says you're
going to die. And we're programmed from birth to not
want to fall down. And so it turns out some

(05:08):
people who suffer from anxiety and have got feelings all
the time in their bellions, some of your listeners know
exactly who they are when I'm talking about this because
I see them in my clinic. It's as if they're
afraid of falling to their death. That's in essence what
anxiety is. It's neuro visceral falling giving into gravity mentally,

(05:31):
and depression is as if you have now hit the
ground and you fall in you're at the bottom now,
so it's all gravitational.

Speaker 2 (05:40):
How long do you have to wear these weighted vests
and ankle weights?

Speaker 3 (05:44):
So it turns out there's some research on this, and
the research has looked at four weeks of weighted vest
and it can lead to weight loss quite amazingly. First
some researchers did this with rats where they put these
weighted tungsten pellets inside the rat and weighted them down,

(06:06):
and then they lost weight. And then they did it
with humans, where they had humans like me and you
right wear these weighted vests. Lost four to five pounds
on average just walking around with those vests on. And
it turns out there's something called the gravitastat, which is
a feedback network in your body that tells your body

(06:27):
when you have too much weight all of a sudden
that you have to let go of some weight, and
it's like a feedback loop. Now, if you gain weight
very slowly, bit by bit, it doesn't work. But if
you gain weight all at once and keep the weight on,
it seems to trigger some weight loss in some people.

Speaker 2 (06:43):
Where can you get these weights?

Speaker 3 (06:45):
Well, you can go online. I have no you know,
dog in this no horse in this race. But you
can go online Amazon wherever look up weighted vests. I
happen to have a few of them, you know, and
some of the nice ones you can change the weight,
so if it's too much for you, you can take
some of the weight out and then as you get stronger,
start adding a little bit more weight every day until

(07:08):
you feel like you can get through the day with it.

Speaker 2 (07:11):
What do they cost?

Speaker 3 (07:13):
I mean, they're not that bad. I want to say,
you know, I don't know, fifty bucks something in that range.
They're not too expensive. Some are nicer than others, like
the ones with the pockets where you weight yourself up
and down, might cost a little bit more, but they're
pretty affordable considering the you know that the costs of
you know, uncontrolled health disorders. If it can help you

(07:35):
lose weight, it's worth it.

Speaker 2 (07:36):
Now. Soon do you start feeling better?

Speaker 3 (07:39):
Well, For the first couple of days, you might feel
a little bit drained. When I started using it, I
actually had a little bit of a headache. After the
first couple of days, I even felt some palpitations a
little bit in my chest, and so, you know, you
have to be careful, and I recommend you talk to
a doctor if you're going to go, you know, pushing yourself.

(08:00):
So it's good to start low and go slow. But
the amazing thing was around day three or four, I
started losing all those feelings and feeling better, and by
a week in I could make it through the day
pretty much no problem without feeling exhausted. And then by
two three four weeks in, I was able to run faster.

(08:22):
I'm a runner. I was able to do more squats,
and I even measured my VO two, which is a
measure of how efficiently you manage oxygen, and my VO
two went up just as a result of weighing my
body down and being heavier.

Speaker 2 (08:36):
Do you find that you sleep better?

Speaker 3 (08:39):
Yeah, so sleep too is gravitational, right, Why do we sleep,
by the way, well, why do we sleep horizontally? One
reason might be is after a long day of fighting gravity,
you need to reperfuse your brain, so the blood flows
back into your brain at night, and it's like giving
your brain a You really need to get that blood

(09:02):
back in your brain and perfuse it. And that may
be part of what's happening. Even with dreams like visual dreams,
if you're lying on your back of your head, all
the blood is flowing into the occipital cortex. The visual
systems are getting activated at night, and so sleep can
be deeper if you've worked harder during the day, and
it's also recharging you for the next day of gravity. Management.

Speaker 2 (09:24):
We'll take your calls next hour with doctor Brennan Spiegel.
His book is called Pull. Where do you get the
book Brennan.

Speaker 3 (09:31):
Anywhere books are sold and go to Amazon right now
it's up for pre order, and or Barnes and Noble
or McMillan.

Speaker 2 (09:39):
What would you say is the single most important facet
of utilizing gravity for us?

Speaker 3 (09:47):
Mm? Wow, single most important? I think. I think we've
talked a bit about it already, which is getting stronger
and losing weight. If we think about the most effect
of therapies in all of medicine, all of medicine, they
come down to working out, getting stronger, losing weight. The

(10:08):
second most important we haven't talked much about yet is
your diet and what we can do with diet to
boost gravity management. What do you think is supplementation, Well,
it depends on the supplements. But what I really am
interested in when it comes to gravity is those trillions
of organisms inside your body and the microbiome that we

(10:31):
co evolved with, and the question is what are they
doing in there? And one of the things that they
do is they create serotonin. Serotonin, most people think of
as a mood chemical makes you feel up high good
positive but it also manages gravity. And it turns out
ninety five percent of your body serotonin is made in
your gut by the microbiome that we live with, and

(10:55):
if you feed it the right things, particularly trip to
fan and trip to fan can haining foods like turkey
for example, in others, then you can start boosting serotonin
levels and this actually helps you fight gravity physically, not
just mentally.

Speaker 2 (11:10):
You've got a book out on the virtual reality. Tell
me how important that is?

Speaker 3 (11:15):
Yeah, that fits into this too. So this book came
out a few years ago, and you know it's based
on this notion of simulation. You know, we may be
living in a simulation right now. We can talk about
that virtual reality is a simulation within a simulation, and
as virtual reality gets better and better, we can do
amazing things with it to improve human health. So one

(11:38):
of the areas my lab works on is how do
we use simulations to non pharmacologically improve pain management, anxiety depression.
And one of the most effective approaches is we put
people in VR and we have them float up into
the heavens literally see what it's like and feel viscerally

(11:59):
what it's like. To break the bonds of gravity, and
that's a very profound effect on the human body, and
we measure that with what it does to the heart
rate and cortisol and stress hormone levels, and the entire
nervous system and brain responds very positively when we use
those visualizations. So my first book is all about that.
It's called VRX.

Speaker 2 (12:18):
Is It Like Dying?

Speaker 3 (12:20):
So we can simulate out of body experiences, and we do,
and we can simulate death. And one of the most
profound experiences I've had in VR is having a full
out of body experience where I floated up out of
my body and I looked back down upon myself, and
what I realized in that moment is that the process

(12:42):
of dying was not catastrophic like it was almost a
spiritual experience. To simulate breaking the bonds of gravity and ascending,
and I know you're going to be talking about angels,
I think tonight as well. We can simulate that in
virtual reality, and there's a lot of excellent evidence that
it can change your perspective on death itself if you

(13:04):
go through a simulated out of body experience.

Speaker 2 (13:07):
Speaking of simulation, you had mentioned that there are some
that believe we're living in a simulated world. What are
the possibilities of that being real?

Speaker 3 (13:17):
Well, I love this topic and that you ask this question,
it's fascinating. I mean, we know that the simulation hypothesis
suggests that our entire universe might be kind of of
an advanced digital simulation, like maybe even a video game,
or the laws of physics are programmed in by some
higher intelligence maybe, And in that context, gravity could be

(13:39):
seen as one of the core rules that are built
into the system, like a fundamental algorithm that keeps the
whole simulation coherent and grounded. And so then if you
think about it that way, what's remarkable, as we've talked about,
is how our bodies and minds and even our emotions
have evolved to basically encode and adapt to this gravitational rule. So,

(14:01):
if we are in a simulation, we are encoding the
bits of data in our universe and transmuting them into
the experience and consciousness of life itself. So we are
consciousness generating biological creatures that literally use the physics of

(14:21):
our reality to enable that consciousness, which is actually why
I think humans have a form of consciousness that AI
cannot because we literally are gravity bound organisms in a
way that an AI is not. We can talk about
that as if you want as well, but those are
my thoughts on that topic.

Speaker 2 (14:39):
Who's the creator of the simulation?

Speaker 3 (14:41):
Yeah, I wish I knew that. I was a philosophy
major back in college. Spent a lot of time trying
to wrestle down that. You know, it's hard to know.
It is hard to know how we can live in
a computational universe such as it is and think about

(15:05):
whether this is fully random chance or if there is
some simulator. And you know, I don't have an answer
for you. I will say that over the course of
my life, having gone through all of the variations of
that belief, I'm starting to pendulum back to there's some
kind of simulator. And that's as far as I can

(15:27):
go right now.

Speaker 2 (15:28):
Going back to Isaac Newton, gravity is far more than
what he thought it was.

Speaker 3 (15:33):
Oh yeah, well, you know, he was a genius. Unbelievable
what Newton was able to accomplish in his day and
to think of gravity and to characterize it, you know,
with an equation. It turns out his form of gravity
was not Although it's a useful tool, it was not

(15:54):
exactly right and Of course, Einstein reevaluated gravity as the
of space time itself around mass, But now we're starting
to see another approach to what gravity might be. So
there's a physicist named Melvinvopson who believes that gravity is
actually the consequence of living in a simulation where information

(16:19):
is compressed like a computer system compresses information. The more
and more efficient we become. That generates gravity as an
offshoot of information theory. So this is yet another view
of that's evolving of what gravity is. So over the years,
gravity has been a lot of things.
