- 🏃♂️ For optimal performance, maintain hydration by balancing water and electrolyte intake, especially during physical activities.
Q & A
What is the recommended amount of water to drink first thing in the morning for hydration?
-The amount depends on the individual's size. For someone around 165 to 170 pounds, 16 ounces of water is suggested, while someone who is 225 pounds might need around 30 ounces.
Why is it advised to drink water slowly rather than chugging it?
-Drinking water too quickly can rapidly increase blood volume, leading to the body getting rid of it faster, which is not efficient for hydration.
How does the timing of water intake before sleep affect sleep quality?
-Drinking a lot of water right before sleep can compromise sleep by causing more frequent trips to the bathroom. It's recommended to sip water in the hours leading up to sleep.
What is the suggested guideline for fluid intake in the three hours before sleep?
-It's advised to limit fluid intake to sipping as needed in the three hours preceding sleep to avoid waking up frequently to use the bathroom.
Why might someone wake up with a dry mouth at night?
-Waking up with a dry mouth could indicate dehydration or mouth breathing during sleep. If it's accompanied by large urinations, it's likely due to mouth breathing.
What is the significance of eating whole foods for maintaining hydration?
-Whole foods often have high water content, which contributes to hydration. Additionally, they are less likely to be highly processed and dehydrated, unlike many processed foods.
How does the water content in food like watermelon compare to other foods?
-Watermelon is over 95% water, making it an excellent hydrating food source. In contrast, foods like biscuits can be as low as 10% water.
What is the role of salt in maintaining hydration when transitioning to a whole food diet?
-When switching to a whole food diet, it's important to add salt back into the diet to replace the sodium lost from reduced processed food consumption, which can help with hydration.
Why is it important to monitor both mouth dryness and urination frequency when assessing hydration status?
-Mouth dryness and urination frequency can indicate different hydration issues. Dry mouth with frequent urination may suggest mouth breathing, while dry mouth without much urination could indicate actual dehydration.
What is the 'five-step cheater guide' mentioned in the script for optimizing hydration for performance?
-The guide includes starting the day hydrated, eating mostly whole foods, managing water intake around sleep, and adding salt back into the diet, which are all strategies to optimize hydration for better performance.
Outlines
💧 Optimizing Hydration for Performance
The first paragraph emphasizes the importance of hydration for physical performance. It introduces a hydration formula, suggesting half an ounce of water per pound of body weight for starting hydrated, and two milliliters per kilogram of body weight divided by 30 to maintain hydration. The speaker provides a 'cheater guide' with a five-step plan to optimize hydration. The initial step is to drink a significant amount of water first thing in the morning to kickstart the day and avoid disrupting sleep with late-night water consumption. The amount of water varies based on body size, with examples given for individuals weighing 165 to 225 pounds. The paragraph also touches on the effects of drinking water too quickly, which can lead to increased blood volume and subsequent need to urinate. It advises sipping water in the hours leading up to sleep and suggests limiting fluid intake three hours before bedtime to prevent nocturnal awakenings to use the bathroom. The speaker also discusses potential reasons for waking up with a dry mouth, such as dehydration or mouth breathing, and suggests solutions like mouth taping to improve sleep quality.
🍉 The Impact of Diet on Hydration
The second paragraph discusses how food choices significantly affect hydration status. It highlights that certain foods, like watermelon, are high in water content and can contribute to hydration without being overly high in sugar or carbohydrates. The speaker challenges common misconceptions about sugar intake, emphasizing that moderation is key, especially for those prone to overconsumption. The paragraph also contrasts the hydrating properties of whole foods, like meat, with the dehydrating effects of highly processed foods, which are often low in water content and high in salt. The speaker suggests that a diet rich in whole foods can naturally increase fluid intake and improve hydration. However, they caution that transitioning to such a diet may require additional salt intake, either through electrolyte supplements or by seasoning food to taste, to maintain proper electrolyte balance.

Transcripts
three parts start hydrated
maintain hydration throughout
part three is hydrate post to fix it
okay we gave you the half ounce per
pound of body weight equation so you
start the training hydrated we gave you
the
you know two milliliters per kilogram
slash body weight divided by 30.
to stay hydrated let me give you the 125
but I can actually just give you sort of
I'm giving you another list here I'm
sorry but it is my five-step cheater
guide
for optimizing hydration for performance
sorry step number one drink a lot of
water first thing in the morning this
gets everything kickstarted get you
going it also saves you from having to
drink a bunch of water at night which is
then going to compromise your sleep
what's a lot depending on how big you
are the general thing I'll tell people
is like one of the very first things you
should do throughout your day you wake
up
go to the bathroom as you're consuming
your sunlight consume water this is
maybe chugging a full glass it's
honestly what I do it's not the best
route but I'll just get 16 ounces 16
ounces or so is great it's fine if
you're larger
um you know I'm 165 to 70 pounds
depending on what's going on maybe a
little higher sometimes if you're 225
pounds maybe that number is 30 ounces
okay so you just sort of scale up and
down and the only reason I say a lot is
it just depends on what you're doing and
I also should clarify I don't really
literally mean chug just like sips
because the faster you drink water the
faster it's going to expand blood volume
the faster it stands blood volume the
faster you get rid of it
um I don't think a lot of people will
know that yeah this is uh maybe this is
clarifying this is also we sort of
talked about earlier if you drink too
much water you'll dilute the system well
if you have a diluted system your body's
first reaction is to rid of water to
bring total blood volume down right
remember if you were to go to a doctor
and they look at your total blood volume
they're like man you're five and a half
liters you're gonna be like holy crap
you're gonna be put on a diuretic
because you don't have a heart attack
blood pressure I wonder if people are
drinking a 16 ounce glass of water or
other fluid all at once before going to
sleep and that's why they're waking up
in the middle of the night totally given
what you just said probably a better
um protocol would be to sip on a glass
of water in the final hour two hours
before sleep generally the number we say
is three hours in the three hours
proceeding sleep you want to basically
limit fluid intake to sipping as needed
I think that's I'm going to start that
tonight because I wake up generally once
per night to use the bathroom and I do
drink some fluids before I go to sleep
mostly because I'm pretty thirsty at
that time yeah
um but I'm gonna start sipping that
water in the uh three hours heading into
sleep yeah so you can actually pay
attention to his um
to go back this is actually I love doing
this stuff but if you're waking up at
night and you have a very dry mouth
not for me all right because it can be
one of two things you might actually be
dehydrated and so then what the mistake
people make is like man my mouth is so
dry I keep getting up to drink water at
night that makes you then pee too much
what that also indicates is probably
your mouth breathing so a lot of ways to
fix people waking up and urinating too
much at night is to tape your mouth and
or use a dilator over your nose and then
what happens is you don't feel like you
have a dry mouth so you don't get up to
consume any extra water throughout the
night so that actually reduces your your
fluid intake so you don't have the
problem of actually now having too much
fluid to do it and so there's another
reasons why mouth taping can really
really help um
if you are having those issues and or
snoring those are not benign that's a
really like you really should get some
work on those um something you're not
sleeping very well is the way I'll say
it it doesn't doesn't necessarily mean
something life-threatening but it's not
a good thing so you're going to run kind
of your triaging things back and forth
so if you're like I'm waking up to pee a
lot but my mouth isn't thirsty okay
great then you may actually have just a
water consumption issue if it is my
mouth is dry but I'm actually waking up
and I'm having these large urinations
then you're not actually dehydrated
you're just breathing through your mouth
if you're waking up and your mouth is
dry
and there's not a lot of pee there then
you actually might actually legitimately
be under hydrated so a little bit of a
game you can play there well that's
super informative I think that
um the point alone that
gulping a bunch of water all at once is
going to cause you to need to excrete
that water
soon after
um is a really important point also for
people that are going to I don't know
give a talk or you don't want to have to
get up to use the restroom you have to
sit through a long meeting yeah um
clearly I'm violating all these rules up
until right now I've been you know not I
sort of followed the seagull approach to
uh to consuming fluids just in
um enormous volumes I'm going to start
sipping um fluids instead
um what are some of the other rules of
hydration so you're going to wake up
you're going to start your day and start
hydrated so you know you're consuming a
larger percentage of your water earlier
in the day then you get all the
performance enhancing effects of water
and you don't have to worry about it
compromising your sleep so that's step
number one also now you're gonna start
your session closer to hydration all
right great number two eat mostly real
Whole Foods
why
interesting what you may or not have
thought about is a huge determinant of
your hydration status is your food
choices if you look at different foods
for example most fruit watermelon
watermelon is like 95 plus percent water
fantastic Source also by the way since
we're here it is not extremely high in
carbohydrate it's not extremely high in
sugar it is by percentage but since it
is almost exclusively water you're
eating it is not something that is
extremely dangerous in terms of sugar I
there alone probably all the things
we've talked about in the six six
episodes uh that comment right there
will probably blow the internet to
pieces and I'll probably get hate mail
for life for it but from people
sugar water throwing watermelons yeah
yeah oh my gosh well I don't think the
point is that sugar is necessarily bad I
think the point is that for most people
they're ingesting too much sugar most
people yeah um and it's interesting
oftentimes the people who are justifying
the ingestion of sugar are exactly the
kind of people that should not ingest so
much sugar so there's a little bit of a
well a user bias the point here is if
you're eating whole real food this is
like now we're kind of splitting hairs
about those things so
so morning hydration
yeah now important Point here
if you compare it to other Foods
um like actually meat is is a very high
percentage of fluid depending on how
well or long you've cooked it you just
remember you said earlier
or 70 water right so if you're eating
meat you're getting actually a big chunk
of water as you cook it of course you
lose some of that but meat can be like
I wouldn't call it a hydrating food item
but it is not as low as something like a
biscuit which can be actually like 10
water that's why it's like dry and dense
which doesn't mean it's bad for you but
there if you're eating highly processed
foods almost by association that means
they've been dehydrated
or portionably right so you're just
getting less total fluid intake in
addition they have also been highly
salted
in general right so now we're in this
position where we're under hydrated and
highly salted bad spot if you now switch
over to mostly again just mostly whole
real food-ish whatever that means to you
then your hydration is going to
Skyrocket you're going to have a lot so
you're eating a ton of food in fact it
should be a large percentage of the
fluid intake you have actually should be
coming from your food and you shouldn't
have to be smashing water bottles after
a water bottle all day in that case
though you do need to add salt back so
we do see this a lot with people who try
to make a transition from maybe a
sub-optimal Nutritional Lifestyle and
they give up a little bit of other
processed food and they come over and
they start having problems because
they're not actually consuming enough
salt
so add that back easy way to do that you
can use electrolytes and we could talk
about those numbers if you want if you
just salt your food that you're making
you know to taste that's going to get
most people in a pretty good spot
