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 6th 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, semblance. 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. All right. Number one, you activate something

called a parasympathetic nervous system. So there's two parts of the autonomic nervous system.

You have the sympathetic which is flight or flight and the parasympathetic which is rest and digest.

So when you eat a lot of food, especially refined 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
