hi guys in this video we’re going to

talk about caffeine okay what is

caffeine caffeine is a central nervous

system stimulant okay it’s involved in

making you feel very awake in your head

increasing your reaction time increasing

concentration increasing your focus but

the question is how does it do it well

it does it by number one blocking

adenosine which is a chemical in your

brain that inhibits the central nervous

system so basically it’s the brakes of

your nervous system so if we get rid of

the brakes we have all accelerator so

that’s one thing that it does to it

increases dopamine if you’re deficient

in dopamine you’re going to be depressed

inability to handle stress fatigue mood

swing attention problems so caffeine

will increase temporarily dopamine okay

like a pleasure neurotransmitter number

three it will increase glutamate now

glutamate deficiency causes mental

fatigue weak motivation attention

problems in mood swings so this is why

people drink coffee to bring their mood

up okay but this is what it’s doing

internally it can act as a diuretic so

it can actually make you pee out more

fluid it can increase your blood

pressure and if you have too much

increase artery stiffness down the road

if you drink coffee chronically now I

don’t think there’s any problem with

drinking some caffeinated beverages

either tea or coffee as long as you have

a small amount okay maybe one in the

morning but I’m talking about the

overconsumption like me in college I

used to drink positive coffee and that’s

what brought my health down and the last

thing caffeine will do it depletes your

vitamin b1 calcium and potassium these

are the three common nutrients that you

need more of when you’re doing a

ketogenic diet but if you’re low in

potassium you’re going to get

constipation skip heart beat atrial

fibrillation you’re going to problem the

sugar cravings and muscle weakness so

you can see there’s a big problem with

too much so if you’re going to do

caffeine do very small amounts of it
