Keto Dangerous? (Studies vs Real Life)

Time: 0

Keto diet and longevity. So most people

Time: 3.6

realize that keto is great for burning

Time: 7.259

fat and losing weight but then they hear

Time: 9.57

on the other side a lot of opponents

Time: 11.759

claiming that the body needs

Time: 13.91

carbohydrate and if you cut it out too

Time: 17.01

extremely you won't live as long and

Time: 19.199

it's unhealthy and side-effects and so

Time: 21.84

forth so let's take a really close look

Time: 24.57

at the mechanisms and what's really

Time: 27.96

going on here. So there's a lot of

Time: 29.76

studies out but one review study I found

Time: 32.43

which was interesting was ketone bodies

Time: 34.59

mimic the lifespan extending properties

Time: 37.71

of caloric restriction so back in 1935

Time: 43.29

they found out that rats lived longer if

Time: 47.7

you fed them less so they reduced their

Time: 52.26

diet they reduced their caloric intake

Time: 55.26

basically starved them by feeding them

Time: 57.75

30 to 50 percent less than a normal rat

Time: 61.14

would eat and they found when they did

Time: 63.48

that continuously then the average

Time: 66.479

lifespan of the rat went from 500 days

Time: 69.21

to 820 days so about a 60% increase in

Time: 73.68

longevity and ever since then there has

Time: 76.95

been this association between calorie

Time: 79.32

restriction and longevity and they've

Time: 82.65

been able to duplicate this in a number

Time: 85.2

of different species so it's not just

Time: 86.759

like rats they've done it with tiny tiny

Time: 89.88

things like yeast or nematodes or fruit

Time: 92.369

flies but they also done it with mice

Time: 94.02

and primates so what is it about calorie

Time: 97.2

restriction that makes you live longer

Time: 99

that's what they try to figure out and

Time: 101.25

they had different theories maybe it's

Time: 103.68

that the cells turn over slower there's

Time: 106.47

less wear and tear maybe it's that the

Time: 109.59

body fat is reduced when you starve the

Time: 112.77

rats

Time: 113.93

maybe the fat is so bad that it it's to

Time: 117.54

sit on your body that it it does bad

Time: 119.67

things and makes you live shorter maybe

Time: 122.88

it's the inflammation because we all

Time: 124.409

know inflammation is is bad and starving

Time: 127.2

reduces overall inflammation may be body

Time: 130.8

temperature because once you restrict

Time: 133.38

once you starve it the body thinks I

Time: 135.3

don't have as much to burn so I better

Time: 137.4

conserve it and turn down the furnace I

Time: 140.55

can last a little longer or insulin

Time: 143.1

they've noticed that a lot of these

Time: 145.23

things seem to do with insulin so let's

Time: 148.17

look at insulin just a little bit closer

Time: 150.06

and realize that insulin is what they

Time: 152.73

call a mitogenic hormone what that means

Time: 157.05

is it increases mitosis and mitosis is

Time: 161.16

cell division or cell replication so

Time: 165.03

anytime a cell makes a copy of itself

Time: 167.61

then it divides one time and they found

Time: 171.54

that you only have so many copies

Time: 174.24

available it's called a hayflick limit

Time: 176.31

and it's tied in to longevity and

Time: 178.86

telomeres and so forth which is a

Time: 181.17

genetic marker of how long you can live

Time: 184.5

based on these cell divisions and we

Time: 187.86

found that insulin increases the

Time: 191.61

turnover rate it increases the rate at

Time: 194.88

which cells make copies so that can be

Time: 198.72

good in terms of of growth or repair but

Time: 202.68

it can be really really bad because it

Time: 205.14

also increases cancer because it makes

Time: 208.68

the cancer cells turnover and replicate

Time: 211.56

faster too and it's been associated with

Time: 215.07

atherosclerosis because it makes the

Time: 219.29

first of all it increases inflammation

Time: 221.55

and a lot of the plaquing is in response

Time: 224.91

to that but it's also been shown to

Time: 226.71

increase the formation of the a

Time: 229.89

thoroughness of the atherosclerosis

Time: 231.63

which leads to heart disease and of

Time: 234.93

course it's been linked to aging because

Time: 237.63

insulin if it tends makes the cells

Time: 240.56

turnover faster then it increases the

Time: 244.59

rate of aging so when we look back

Time: 247.74

because they could never quite figure

Time: 249.81

out which one of these is it but once we

Time: 251.85

look at this we realize that insulin has

Time: 254.46

to do with virtually every single one of

Time: 257.1

them because insulin increases the

Time: 259.83

turnover insulin is a fat storing

Time: 263.31

hormone insulin is inflammatory

Time: 265.91

increases in

Time: 267.23

Meishan body temperature I don't know if

Time: 270.86

that would be directly linked

Time: 272.24

specifically to insulin and of course

Time: 275

the insulin is linked to insulin so most

Time: 276.89

of the reasons for the mechanism is tied

Time: 280.52

to insulin so what happens when we storm

Time: 283.76

the rats well there's two things that

Time: 286.85

always go together first is that we

Time: 289.91

reduce insulin because insulin is there

Time: 293

to process carbohydrates and when you

Time: 295.46

eat less

Time: 296.75

you're gonna eat less carbohydrates

Time: 298.22

there's less need for insulin you're

Time: 301.4

also going to increase ketones

Time: 303.62

so these always go together insulin and

Time: 307.15

less insulin and more ketones they

Time: 310.94

always go together

Time: 312.35

and it is always healthy it's always

Time: 317.09

favorable except in one case and that is

Time: 321.17

in type 1 diabetes when the insulin goes

Time: 325.01

to 0 and then the ketones go sky-high

Time: 329.15

which is a pathologic disease condition

Time: 332.51

as long as you have the ability to make

Time: 335.33

some insulin then it is healthy to

Time: 339.08

increase the ketones and there's

Time: 341.42

different ways to increase the ketones

Time: 343.97

so we know it happens in starvation or

Time: 346.52

in fasting which is prolonged periods of

Time: 349.67

not eating whether it's voluntary or

Time: 353.48

involuntary fasting is generally

Time: 356.3

considered voluntary and starvation's

Time: 359.45

considered involuntary exercise will

Time: 363.35

increase ketones and low carb diets with

Time: 367.04

increased ketones so the question then

Time: 369.5

becomes which one is it that produces

Time: 372.95

the beneficial results is it less

Time: 375.2

insulin or is it more ketones and we

Time: 379.31

don't have a clear answer on this but we

Time: 381.5

don't really have to worry about it

Time: 383.33

because one always follows the other so

Time: 386.24

if we get one we always get the other

Time: 389.2

they both seem to have tremendous

Time: 392.08

benefits to themselves if we reduce

Time: 395.09

insulin we reduced 95% of all

Time: 397.46

degenerative disease when we increase

Time: 400.16

ketone

Time: 401

we tend to get certain observable

Time: 403.67

benefits as well we can treat various

Time: 406.1

different conditions with it we know

Time: 409.16

obesity and diabetes improve with

Time: 412.58

ketosis but they've also found a lot of

Time: 415.7

other neurological conditions that have

Time: 419.12

pretty much been resistant or they

Time: 423.29

didn't get any results at all until they

Time: 426.77

tried ketones and things like

Time: 428.5

Alzheimer's and Parkinson's and ALS

Time: 431.81

really severe neurological diseases tend

Time: 436.1

to get better with more ketones one more

Time: 438.8

thing that ketones do is they're

Time: 441.14

metabolized differently inside the cell

Time: 443.99

inside your cell you have mitochondria

Time: 446.63

which produce most of the energy for you

Time: 450.28

the vast majority of all energy used is

Time: 453.62

in the mitochondria and they have

Time: 455.21

different pathways and it turns out the

Time: 458.03

ketones go through a more efficient

Time: 460.76

pathway they can bypass a step or two

Time: 463.61

and therefore they can produce more ATP

Time: 466.13

or more of your energy currency per unit

Time: 470.51

of oxygen so it's more efficient and it

Time: 475.01

produces less damage less oxidative

Time: 478.1

damage by burning ketones and burning

Time: 480.47

other sources of fuel and one thing we

Time: 483.08

have to realize which this is my opinion

Time: 485.6

based on a bigger perspective and a way

Time: 488.87

of observing things naturally is you

Time: 491.87

don't improve all these different

Time: 495.14

conditions you can't improve such a wide

Time: 499.4

variety of condition by making someone

Time: 502.01

less healthy so the biggest detractor

Time: 506.15

for the the opponents the biggest

Time: 508.34

argument is that sure it helps for for

Time: 511.13

obesity and diabetes but we don't know

Time: 513.65

the long-term effects we it's it's bad

Time: 516.77

for this or you have to have carbs or

Time: 518.96

fat is is bad and they're pulling these

Time: 522.169

statements but they can't really put the

Time: 524.54

picture together but the one picture I

Time: 526.7

want to keep in mind is if it brings

Time: 529.76

together if you'd improve such a wide

Time: 532.1

variety of conditions then

Time: 534.329

it's not a bad thing so ever since 1935

Time: 537.929

when they first figured this out the

Time: 539.999

calorie restriction has been a huge

Time: 543.17

topic it's been something that people

Time: 545.759

say oh yeah if only I could do that

Time: 549.119

if only I could restrict my calories for

Time: 552.029

the rest of my life then I would live a

Time: 554.579

whole lot longer but the problem is when

Time: 558.54

you starve yourself then unless you want

Time: 561.809

to be a rat and they put you in a cage

Time: 563.67

and just feed you half of what you want

Time: 565.949

to eat you're not going to be able to

Time: 568.019

keep it up because hunger doesn't feel

Time: 570.569

good the vast majority of people are not

Time: 573.839

going to be able to keep it up so we

Time: 576.449

know that calorie restriction improves

Time: 579.149

insulin and ketosis reduces insulin

Time: 581.97

increases ketones but you get hungry

Time: 586.639

so wouldn't it be nice if there was a

Time: 591.149

way that you could reduce insulin and

Time: 595.85

increase ketones

Time: 597.709

without going hungry and I know I've

Time: 602.549

heard about something I think there's

Time: 605.04

there's something I heard that could do

Time: 607.949

that but no wait wait here it's coming

Time: 610.86

to me

Time: 611.309

oh yeah the ketogenic diet that's what

Time: 615.54

it is because when people do that they

Time: 619.499

reduce insulin they increased ketones

Time: 621.769

but they don't go hungry and this is not

Time: 628.079

so easy to understand for people who

Time: 630.54

haven't tried it but once you try then

Time: 633.48

you notice that your body wants fewer

Time: 636.72

meals because fat is very satisfying

Time: 639.66

then you can go longer between meals so

Time: 644.129

in the end you end up eating a little

Time: 646.889

bit less maybe not less calories

Time: 650.279

probably a little bit but maybe not but

Time: 652.889

the main thing you get is reduced

Time: 655.319

insulin and increased ketones so you get

Time: 658.41

these anti-aging benefits you get all

Time: 662.759

these health benefits because it is

Time: 665.999

primarily about

Time: 667.83

the insulin and possibly some about the

Time: 671.61

ketones but it's certainly not about the

Time: 674.55

calories the reducing of the calories

Time: 677.82

only results in changed insulin and

Time: 681.45

ketones it's not the calories per se so

Time: 684.24

please share this video with anyone that

Time: 686.46

you care about because we want to get as

Time: 689.22

many people as possible healthy we want

Time: 691.92

to help people understand the true

Time: 694.34

principles the true mechanisms around

Time: 697.17

health not just memorize a laundry list

Time: 700.68

of things to do because that's

Time: 702.75

short-lived but once we understand the

Time: 705.3

mechanisms the big picture then we can

Time: 708.24

start creating a long term healthy

Time: 710.88

lifestyle so leave your comments and
