Transcripts

Speaker:

You know, it can cause

glycation in the skin.

Speaker:

It can cause some gumming up in the brain.

Speaker:

It can cause problems with the pancreas.

Speaker:

From when you're a little child

you probably had been rewarded at

Speaker:

least once with sugar. If you're

a good little boy or girl,

Speaker:

they might give you a sweet, and so

you ended up developing a sweet tooth,

Speaker:

some people call it. But what is

the impact that sugar has? I mean,

Speaker:

without a doubt, our brain requires sugar.

Speaker:

It's the primary nutrient of the brain.

Speaker:

But excessive or deficient amounts of

sugar going into the brain can cause

Speaker:

cognitive dysfunction, or

let's say cognitive impairment,

Speaker:

let's put it that way.

Speaker:

So I'd like to talk about sugar for a

moment and the impact that sugar has.

Speaker:

First, I'd like to talk

about taking sugar. There are

different types of sugars.

Speaker:

There's complex carbohydrates

that break down into sugar slowly.

Speaker:

There are simple sugars that go right

into the bloodstream and spike it,

Speaker:

and then usually have it fall.

Speaker:

And then there's also natural sugars

from eating fats and proteins that body

Speaker:

metabolizes and creates back into

sugar. The brain requires sugar.

Speaker:

So I don't want to say that sugar's

bad or good, but like anything else,

Speaker:

even water, too much water or too

little water can cause problems,

Speaker:

and the same thing with sugar.

Speaker:

If we eat more sugar than ideal,

Speaker:

it definitely impairs our cognitive

function. We get a spike, we get manic.

Speaker:

When we get manic, we tend to

see positive and optimistically,

Speaker:

and we're basically blind

to some of the downsides.

Speaker:

And then when we fall

and the spike goes down,

Speaker:

we tend to be more

pessimistic and irritable,

Speaker:

and therefore we are not thinking

clearly and not centered and not pros.

Speaker:

So anytime we eat spikes of sugar,

Speaker:

it affects our cognitive function,

it causes a spike and then a decline.

Speaker:

And what's interesting, if

you eat sugar more than ideal,

Speaker:

you can create a leptin

resistance and as a result of it,

Speaker:

you can then lose the feedback mechanism

that the hormone leptin normally does

Speaker:

to let you know when you're satiated

and you can tend to overeat.

Speaker:

So excessive amounts of

sugar also has an impact on

Speaker:

leading to overeating and then

obesity and type two diabetes

Speaker:

and cardiovascular conditions. And

eventually, if we gain some weight,

Speaker:

it can affect our hips and our

joints and our knees and our overall

Speaker:

energy levels,

Speaker:

which makes us more vulnerable to

emotional vicissitudes and emotional

Speaker:

volatilities. So the question is,

Speaker:

is are you overeating sugar ?

If you're going and having a Starbucks,

Speaker:

you might want to go and do a little

research on how many sugar teaspoons are

Speaker:

sitting in a Starbucks. I know for myself,

Speaker:

I learned from Paul Bragg when I

was 17 years old not to eat white

Speaker:

sugar, white flour or white salt.

Speaker:

So I haven't added salt to my diet or

eating sugar in my diet or eating white

Speaker:

flour in my diet for 51 years.

Speaker:

I try my best to try to fill

my body with food that's real.

Speaker:

That's not empty calories. But

in the process of doing it,

Speaker:

I do eat fruit, fruit sugars. I do

eat vegetables that have sweet in it,

Speaker:

that's like carrots and beets.

And I also do eat breads.

Speaker:

And that breaks down as

complex carbohydrates to sugar.

Speaker:

And my brain has adequate sugar.

Speaker:

But I noticed that if for some reason

there's a little bit more sugar than

Speaker:

normal, that's why I don't

drink a lot of fruit juices,

Speaker:

I'll have just a sip of one,

Speaker:

because it's too much sugar and it spikes

and then you go down and when you do,

Speaker:

you're volatile and you're emotional

and your brain doesn't, you know,

Speaker:

it doesn't have stability. In fact,

Speaker:

if you end up with too much

sugar spikes and then let downs,

Speaker:

you automatically tend to get your brain

focusing on your amygdala response.

Speaker:

You tend to be a more

emotional and volatile.

Speaker:

And instead of getting into your

executive function where you have

Speaker:

self-governance and executive

functions where inspired vision,

Speaker:

strategic planning, executing plans,

self-governance, you tend to lose that.

Speaker:

You tend to be irritable and you'll

tend to bite and spite and react.

Speaker:

So I tell people that you might

moderate your sugar intake.

Speaker:

It really does make a difference.

Speaker:

It's not hard to prove and see if you

just moderate it for a week and see the

Speaker:

impact. But you might

want to stop and ask,

Speaker:

is the coffee with the sugar,

the tea with the sugar,

Speaker:

the desserts with the sugar,

the foods, without realizing it,

Speaker:

that's fast foods that has

sugar in it, are you really,

Speaker:

even the yogurts out there,

I I eat plain Greek yogurt,

Speaker:

I don't eat anything

that has sweets in it,

Speaker:

so I'm a very much a carbohydrate

Speaker:

calm down carbohydrate person. You

know, it affects your your teeth,

Speaker:

it affects your immune system, it

affects your cardiovascular system,

Speaker:

it affects your emotional volatilities,

Speaker:

it makes you decrease your probability

of having cognitive centeredness and

Speaker:

mastery by overeating

sugar. But at the same time,

Speaker:

if you are fasting and you don't have

any sugar that's released in the brain,

Speaker:

then you end up with problems

too. So too little is not wise,

Speaker:

it's just the right amount of food.

And my experience is that, you know,

Speaker:

I don't add sugar and I don't add

honey and I don't add sweetening,

Speaker:

I don't eat anything with sweets

like that. It's just not my thing,

Speaker:

other than fresh fruit. That's

the sweetest thing I eat.

Speaker:

And I don't have volatility.

I have stable energy and it's,

Speaker:

and my brain function keeps

alert and sharp because of that.

Speaker:

So I'm just letting you know that it

might be wise to stop and take a look and

Speaker:

do an inventory about your

sugar intake. You know,

Speaker:

it can cause glycation in the skin. It

can cause some gumming up in the brain.

Speaker:

It can cause problems with the pancreas.

Speaker:

When you do you get feedbacks in

the brain and back in your feedback,

Speaker:

as I said to leptin and ghrelin,

it throws off your eating patterns.

Speaker:

It also, if it's eating too much

sugar and creates a need for insulin,

Speaker:

because your blood

sugar's so high, it's got,

Speaker:

it's like stimulating it with

glucagon, it now needs some insulin,

Speaker:

you can eventually burn out your pancreas

trying to create that much insulin

Speaker:

and overdo it.

Speaker:

And there's definitely signs that it

affects the brain when it does it.

Speaker:

The brain has to have a stable,

steady centeredness of sugar.

Speaker:

And if you spike it and then,

you know, go the other direction,

Speaker:

sometimes you overeat on sugars and sweets

and stuff and then you end up having

Speaker:

a high, as you know,

Speaker:

and get manic and do crazy things and

set too big a goals in too short of

Speaker:

timeframes, then crash and then feel

like you can't accomplish things,

Speaker:

and all these things impair the executive

function and stop you from mastering

Speaker:

your life. And the other way around,

Speaker:

I found out that people who are not living

by priority, not bringing the blood,

Speaker:

glucose, oxygen into the forebrain,

not having executive function,

Speaker:

not moderating their behaviors,

Speaker:

allowing themselves to go

back into their amygdala,

Speaker:

which requires a little less sugar

than the executive functioning areas,

Speaker:

then what happens is that area starts

to make us impulsive and instinctual and

Speaker:

make us, you know, avoid and seek

and be distracted and emotional.

Speaker:

And we're not centered and focused.

So if we don't, it works two ways,

Speaker:

if you're not living your life

by highest priority actions,

Speaker:

you tend to go in and activate your

amygdala. And at the same time,

Speaker:

if you're eating sweets,

Speaker:

you tend to also activate the amygdala

and not the executive function.

Speaker:

So cognitive impairment is going

on when you overeat sugars.

Speaker:

And I tell people just to be

moderate on it. Like I said,

Speaker:

if you go to the Starbucks and you go

there and they put a load up a bunch of

Speaker:

syrup in there, corn syrup and

things of this nature and sugar,

Speaker:

and then you add sugar to it,

this to me is insane. I mean,

Speaker:

if you look at how many,

Speaker:

just go look on the line and go look

at how much the average person consumes

Speaker:

sugar, the amount of tablespoons or

pounds of sugar that people eat in a year,

Speaker:

it's ridiculous.

Speaker:

And they wonder why they have health

problems and cardiovascular and over,

Speaker:

you know, obesity. I mean,

Speaker:

if you go look at pictures in

the:

Speaker:

America, you didn't see

the obesity we have today.

Speaker:

And part of it's because of sugar intake.

Speaker:

We have complex and simple sugars that

we're overeating and we're not being

Speaker:

told, we're not being educated, or if we

are being educated, we're ignoring it.

Speaker:

And I'm just very grateful I learned

from Paul Bragg when I was 17 that that's

Speaker:

not the thing to feed your body with.

Speaker:

You're either living to eat or eating

to live. And I'd prefer to eat to live.

Speaker:

I'd rather ask myself what's the highest

priority things I can be filling my

Speaker:

body with and to help me have

the most cognitive function.

Speaker:

I have an important function of

educating and researching and learning.

Speaker:

I want my brain working. So

that's why I don't eat sugars.

Speaker:

I don't add sugars to my diet other

than simple fruit and in moderation.

Speaker:

And I have steady stable

energy because of that.

Speaker:

So I tell people to moderate their sugars.

Speaker:

And I didn't say eliminate them, I

just said moderate them. Eat wisely.

Speaker:

You know,

Speaker:

think about what you're actually feeding

your body and think about the amount of

Speaker:

sugars that you're consuming, because

it's going to pay a price. You will,

Speaker:

like I said, type two diabetes is

not necessarily caused by the sugar,

Speaker:

but it does wear down the pancreatic

function if you just consume

Speaker:

sugars constantly and eventually it

is a factor in diabetes. And again,

Speaker:

with the leptin resistance, that's

another factor of overeating.

Speaker:

And both of those conditions we know are

leading to problems and we don't even

Speaker:

realize we're doing that. So be moderate,

Speaker:

stop and reflect and look

at what you're eating.

Speaker:

And stop and reflect and look

at what you're prioritizing.

Speaker:

If you're not prioritizing your day

and living by your highest values and

Speaker:

getting your executive function

to govern your behavior,

Speaker:

and if you're not prioritizing what you're

eating and making sure you're eating

Speaker:

to live and perform and not just

eating for immediate gratification,

Speaker:

which is sugar, because

people want a reward,

Speaker:

and it's one of the most addictive

compounds you can find on the planet is

Speaker:

sugar. I mean, people think,

oh my God, I love you,

Speaker:

I'll give you chocolate

and sugar and sweets,

Speaker:

and that's a crazy message to give

somebody because it's not to their

Speaker:

advantage to overeat sugar.

But a little moderation,

Speaker:

I'm not against having

your sweet occasionally,

Speaker:

but just be aware that the content of

what you're feeding your body is affecting

Speaker:

your psychology.

Speaker:

And if you want to maximize your mental

function and your cognitive function,

Speaker:

eat wisely. Prioritize what you're

eating, prioritize what you're doing,

Speaker:

prioritize what the actions you're taking,

Speaker:

prioritize who you're associating with.

If you're not prioritizing your life,

Speaker:

other people are going to infiltrate it,

and impulsive behaviors will take over.

Speaker:

If you're not, I always say

that impulsive, addictive,

Speaker:

and compulsive behaviors and immediate

gratifying behaviors are compensations

Speaker:

for unfulfilled highest values.

Speaker:

That's why I tell people to make sure

that they prioritize their life and

Speaker:

prioritize their actions and

prioritize their food. If you do that,

Speaker:

you're more likely to keep yourself stable

and steady and focused and energized

Speaker:

and vital and help have wellness.

Speaker:

Without a doubt there's

effect of gaining weight.

Speaker:

If you've gained any weight and

you've added too much sugar,

Speaker:

you're paying a price. And I could

go down the list, I mean from tooth,

Speaker:

as I said, cardiovascular, weight, I mean,

Speaker:

I've seen people that gain a little

bit of weight and they're only 10 to 20

Speaker:

pounds overweight, but every pound they're

overweight it affects their joints,

Speaker:

it affects their cardiovascular

function, I mean,

Speaker:

it just goes on and on. So take the

time to prioritize what you eat.

Speaker:

Take the time to prioritize what you do.

Speaker:

Take the time to prioritize what

actions you're taking every day,

Speaker:

who you're associating with every

day, how you're living your life.

Speaker:

If you're not living for an inspiration,

Speaker:

you're probably going

to fall for desperation.

Speaker:

And eating sugar is not the

way to maximize your potential.

Speaker:

Eating excessive sugar. Eat

moderately. Sugar has its benefits,

Speaker:

it has its drawbacks. Your

brain must have it for fuel,

Speaker:

but it doesn't require you to eat sugar

all day long. Eating natural foods,

Speaker:

fats and proteins and other foods,

Speaker:

your body knows how to

convert that into sugar.

Speaker:

It has sugar metabolism to do that

to make sure your brain is stable.

Speaker:

But just know that if

you eat simple sugars,

Speaker:

stuff that you see in

quick foods or whatever,

Speaker:

you will end up having spikes and troughs

and you'll increase volatility and

Speaker:

you'll be more emotional and you'll be

less stable and your cognitive function

Speaker:

will be impaired. You'll be manic

and then depressed and you know,

Speaker:

hyper and then eventually

irritable. And if you want that,

Speaker:

then I guess that's fine,

but you'll pay a price.

Speaker:

It's wiser to eat moderately and

think about what you put in your body.

Speaker:

So I just know that that's one of the

reasons when I teach the Breakthrough

Speaker:

Experience, I teach people

how to prioritize their

life, prioritize their doing.

Speaker:

Imagine this, if you have

something really, really,

Speaker:

really important to do and

you know it's happening,

Speaker:

you're about to get married or you're

about to go and put on that wedding dress

Speaker:

or you're about to go on a beach holiday,

Speaker:

and you know you're going to

have to be looking your best,

Speaker:

you will very discipline yourself

because you have something meaningful and

Speaker:

priority that you're focusing

on. As a result of it

Speaker:

you don't tend to go into volatilities

and you don't tend to overeat sugars,

Speaker:

because you're more disciplined,

because you know better.

Speaker:

But if you don't have anything that's

filling your day that's inspiring to you,

Speaker:

you're more vulnerable to engage,

Speaker:

that's why most people will blow their

diet on Friday night and Saturday night

Speaker:

and Friday and Saturday afternoon and

evening or whatever and then they'll get

Speaker:

back in discipline again by Sunday

night because they know they've got

Speaker:

accountabilities and responsibilities

on the following day.

Speaker:

That's why I'm a firm believer in keeping

yourself busy in high priority actions

Speaker:

so you're not as vulnerable to your

immediate gratifying amygdala's responses.

Speaker:

Because that's when you tend

to want to overeat sugar.

Speaker:

And then the sugar then

has a vicious cycle,

Speaker:

it's affecting executive function

and you get into a vicious cycle.

Speaker:

That's why prioritizing what you do

and prioritizing what you're eating is

Speaker:

important.

Speaker:

That's why in the Breakthrough Experience

I teach people how to take command of

Speaker:

their priorities, take command

of what their values are,

Speaker:

prioritize what they're doing,

Speaker:

asking themselves really what's

priority as far as eating,

Speaker:

prioritizing who you're hanging out with,

Speaker:

if you're hanging out with people that

are very inspired by what they're doing

Speaker:

and going places in life, you'll

tend to move in that direction.

Speaker:

If you hang out with people

that are victims of history,

Speaker:

you'll hang out in that direction,

you go in that direction.

Speaker:

So prioritize what you do in your

life and watch the difference.

Speaker:

That's why I teach in the Breakthrough

Experience every weekend to help people

Speaker:

take command of their life and be masters

of destiny, not victims of history.

Speaker:

And sugar in excess does not help you

become master of destiny. In moderation,

Speaker:

like many things, moderation

and consistency is one thing,

Speaker:

but excesses will, you pay a

price for that. So compensate,

Speaker:

for this maybe excess sugar by

maybe stopping and reading and reflecting

Speaker:

and thinking, is this really the highest

priority thing to feed my body with?

Speaker:

It's your body. It goes by

quick. Your life goes by quick.

Speaker:

I'm nearly 70 years old and I'll

be 70 in a few months and here I am you

Speaker:

know, I realize how fast that goes.

Speaker:

So you want to feed your mind and

feed your body wisely. Anyway,

Speaker:

that's my message for today and I hope

to see you at the Breakthrough Experience

Speaker:

so I can teach you how to prioritize

your daily actions according to your

Speaker:

highest values and to prioritize what

you're eating so you can take command of

Speaker:

your life and get the most out of life,

Speaker:

because life goes by pretty quick and

you might as well do everything you can

Speaker:

with everything you were given.

Speaker:

I look forward to seeing you at the

next little weekly presentation.
