This is my dear friend Dr. Will Li.
(audience applause)
Will, how long has it been since your groundbreaking book,
"Eat to Beat Disease" came out.
(audience applause) About four years.
I can't believe it's been four years.
Everybody from Bono and Edge to my mom, she's 84 now,
loves this book.
I've read it front to back.
We're all obsessed with it here on our show.
We've done many segments on it and about it
and now I'm very happy to say
that coming up very soon in the early spring, right?
That's right.
Is the follow up "Eat to Beat your Diet"
instead of disease. (audience applause)
So, this has something to do with intermittent fasting
and I trust Will so I'm gonna try and keep an open mind
and a lot of my friends do intermittent fast.
They swear by it, they look great.
So, I'm gonna keep an open mind because I love you.
But, let's start with what the premise of this is for you.
Where did you start with this project?
Right, so my research has actually taken me
into the metabolism of the human body
which is critical for our health.
Metabolism are the chemical reactions
that run our entire body, whether we're healthier
or whether we're sick.
We actually want to be in a really good state of balance
and here's a thing about intermittent fasting
and it's, again, not a new idea's, it an ancient idea,
is that intermittent means every now and then
and fasting means you're not eating.
Well, we actually do this every single day
when we're sleeping we're not eating and during the day-
Well, most of us.
I do know some late night snackers, let me tell you.
So, most people who do it for dieting,
they do 16 and eight, which means that they're not eating
for 16 straight hours and everything they're eating
is happening within eight hours.
Within eight hours of their day.
But, the key with the metabolism is really understanding
how this actually works.
So, when our metabolism is set up and we're eating,
it can't actually lose weight.
It's set up to not lose weight.
So, you gotta stop eating in order to be able
to lose weight, to burn energy.
To burn more energy than you're eating.
That's right.
So, there's a hormone in our body called insulin.
Insulin, when we're eating goes up.
So, you can actually see this in the seesaw,
insulin up when we're eating and burning fat goes down.
Now, when we're actually fasting and not eating-
Insulin goes down.
And you can, your metabolism can burn fat
so you can actually lose weight.
But, that's not the most interesting thing.
The most interesting thing is that the latest research
shows that intermittent fasting
can actually help us age more slowly.
So, therefore there's a double whammy from this.
You can actually improve your metabolism
and you can slow down aging as well
and we actually have a little graphic of this
which is basically in our cells
and on the end of the DNA is a little fuse
and just like a fuse, it burns down shorter and shorter
as we get older and older.
Now, how do we know this?
We know this cause our skin wrinkles,
we know this 'cause our muscles get weaker
and our memory starts to go
and here's the latest research on fasting.
Fasting actually slows down the process of cellular aging.
Of burning the candle on both ends.
Exactly, which you and I both know.
Oh boy, do we know.
And what's really cool is that there's even new research
showing that fasting can trigger a protein
in your circulation that slows down the aging
of your arteries so your circulation gets younger.
When we have a healthy circulation
we can fight heart disease,
we can fight diabetes, we can fight Alzheimer's
and for skin, it turns out we need really good circulation
for our skin so it can glow the way we want it to glow.
So, actually slowing down that process
actually helps make our skin look better as well.
It's the best sell I ever heard on this yet.
(audience applause)
Now is there a formula?
Is there a zone?
Where do you put the 16 hours versus the eight hours,
can you skip breakfast, eat at noon, eat until eight,
but then nothing after eight or is there a science
to where you place those hours in your day?
It's gotta work for every individual person.
It's gotta work in their life.
You can place it wherever it works for you.
and you don't have to be so hardcore about it either.
