so let’s talk about that after lunch

siesta where you want to take a nap and

why that is due to carbohydrates more

than any other reason now there are many

countries that take a siesta

and by the way siesta comes from the

Spanish word meaning nap and the Latin

word for sixth hour and that refers to

the countdown from dawn meaning midday

so there are many countries known for

these siestas Mexico certain countries

in South America Italy Philippines

Vietnam certain Mediterranean countries

southern Europe and Spain and of course

in America we don’t really officially

say that we have a siesta but we

basically fall asleep in front of our

computer right after lunch

so the question is is it normal for

someone to get tired after eating now

there’s actually a medical term for this

post prandial which means after a meal

zomlings and that means food comma and

of course this is a common feature for

diabetes so when you have the

combination of especially refined

carbohydrates and volume of calories

together it can really create a blood

sugar spike and an insulin spike both of

these are going to make you tired now

the question is why would they make you

tired

there’s several mechanisms going on that

go beyond the insulin resistance

mechanism where you’re having a lack of

fuel go into the cell alright number one

you activate something called the

parasympathetic nervous system so

there’s two parts of the autonomic

nervous system you know the sympathetic

which is flight-or-fight and the

parasympathetic which is rest and digest

so when you eat a lot of food especially

we’re falling carbohydrates you’re going

to activate this system over here and

inhibit this system and you’re going to

want to take a nap so that would be the

gut brain connection and with that

you’re going to have less blood to the

brain and more blood into the digestive

system so try to be awake when you don’t

have the amount of blood to the brain

it’s a little more difficult all right

three decreases the arousal pathways in

the hypothalamus in the brain making you

tired

and number four and this is interesting

when you consume a high carb diet you’re

gonna absorb certain amino acids but not

others specifically you’re gonna absorb

valine leucine isoleucine but not

tryptophan so tryptophan is going to be

absorbed through the blood-brain barrier

and it’s gonna directly turn into

serotonin and melatonin the sleep

hormone so if you live in any one of

these countries or in the US I want you

to try an experiment like in Mexico you

would have tortillas and corn based type

things rice Italy you’re gonna have

pasta Philippines in Vietnam you’re

gonna have rice noodles the

Mediterranean you’re gonna have more

pasta and bread southern Europe well you

might have potatoes or some other starch

and in Spain you’re gonna have more

carbs so here’s a challenge try and not

consuming carbohydrates at your lunch

for one week and you’re going to find

your energy is going to go straight up

the need for a nap is not going to be

there and for those of you that are new

to my channel check out this video on

low carbs it will tell you exactly what

to eat
