Let's talk about what happens on the inside of your body when you're fasting

so over here we have a start of a fast and we go 24 hours 48 and 72 so there's

程度副詞

a lot of really magical things that happen when you fast our bodies have

developed over a long period of time and have adapted to starvation many many

times so we have all these unique proteins that get expressed or turned on

that have to do with your brain doing better the different parts of your body

is surviving better our bodies have not adapted to the frequency of eating like

we do now like every three hours so right around 12 hours we get this spike

in growth hormone growth hormone is the anti-aging hormone it's the main fat

burning hormone it's the hormone involved with healing joints and it's

involved with protein synthesis or making different new proteins some

people take growth hormone to get injected I don't recommend it but they

take it to help heal certain parts of your body but guess what

fasting will trigger it automatically so just by the fact that you're fasting you

can increase growth hormone and of course exercise will also increase

growth hormone as well so it starts about 12 hours and it increases as you

go on and on now at about 18 hours you start developing something called autophagy

autophagy is an interesting thing that happens with your body where you start

recycling old damaged proteins and microbes as well one type of protein

would be the advanced glycated end products which basically when you

combined glucose with a protein it becomes very sticky so let's say you're

on a high carbohydrate diet and that sugar combines with your own protein in

your body and that starts to glide Kate or just kind of destroy some of the

proteins in your body and then they don't function anymore and they get

sticky and they clog things up well guess what your body will start cleaning

all that up and turning these damaged proteins into new amino acids where your

body can use them amyloid plaquing which occurs in the

brain and other parts of the body is a type of protein that can be cleaned up

with a toffee gene so it's any type of cellular proteins that are not working

anymore in your body autophagy will start cleaning that up and

start to renew the tissue and it starts right about 18 hours and it gets more

and more and more as you start fasting in about 24 hours and a little bit

longer you start to really deplete this glycogen Reserve this storage supply of

glucose in your liver so the more that the liver is depleted with glycogen the

more you're going to be running on ketones as the alternative fuel and if

you have a fatty liver for example your body will start using that fat and

turning that into ketones so your body is finally able to start tapping into

this stored energy and you're running more and more on ketones which is a

superior fuel and because you're running on ketones ketones are an appetite

suppressant so your hunger goes away cravings are gone there are antioxidants

so you're building up your antioxidant reserve they provide more oxygen so your

body is running out more oxygen less co2 then it's more efficient and because

ketones are a much more efficient fuel than glucose the thyroid does not have

to work as hard and you may find that your t3 is a little bit lower but the

thyroid stimulating hormone is normal and all that means is your thyroid is

adapting to this new type of fuel now some other cool things that are

happening right around 24 hours is that your inflammation is dropping

significantly if you wanted to even speed it up more you can add some

vitamin D to that and that will really help you so any type of conditions that

involve inflammatory states like arthritis bursitis autoimmune type

conditions start to improve about 24 hours you start getting more gut healing

because the gut now doesn't have to work so frequently with the gallbladder being

stimulated and the pancreas stimulating its enzymes the gut finally has a chance

to just chill out so if you have this condition called SIBO which there are

microbes in the small and testin and they should normally be in

the large intestine that starts to become corrective you start increasing

stem cell in the gut so your gut starts to heal the heart loves ketones way

better than glucose so you start getting improvement in the cardiovascular

function and as well as the brain function there's something called BDNF

this is a factor that helps make new brain cells so your brain starts to

repair at 24 hours as you keep going on you would think you're going to be

losing muscle protein but that's not really what happens because your body

becomes more efficient and there are certain genes that are sparing proteins

so it's not using muscle protein so the efficiency of fuel is much better plus

with autophagy you're using the old damaged proteins and giving you new

protein so the combination is really good so the amount of nutrition that you

really need to run the body is a lot less because the body just dows down and

it can run on less amount of nutrients so that's a positive thing now the other

thing that happens during autophagy is that you're also cleaning out microbes

and fungus and mold and yeast and to kill off those microbes your body

develops certain oxidants and you also have antioxidants on the flipside so

your body actually makes things like hydrogen peroxide to kill off microbes

but it also in the left side makes its own antioxidants to actually protect the

body against the oxidation so we have this entire balance it's only when we

have lower amounts of antioxidants and higher amount of accidents that we get

this thing called oxidative stress which things start breaking down but when

you're doing fasting you're getting a nice balance of more antioxidants and

your body is starting to heal now when you get to 48 hours you really start to

stimulate the stem cells these are undifferentiated cells in other words

they're cells that don't have a purpose so they can turn into this tissue or

that tissue depending on what the body needs so you start to stimulate the stem

cell and get more healing and more repair more anti-aging

you also get decrease risks of certain types of cancer you get shrinkage of

certain tumors you start making more mitochondria now if you push it and go

up to 72 hours you get even more stimulation of stem cells okay in better

immune function but when you actually get into 72 hours or greater I recommend

you do that as a periodic thing simply because a lot of people going into this

have nutritional deficiencies in there if you jump in too fast you can get a

little bit dizzy you can have some side effects so you want to gradually do this

over a period of time but those are some general things that happen when you're

fasting I recommend doing intermittent fasting on a regular basis okay and

probably a good average pattern of doing this would be doing 18 hours of fasting

with a six-hour window so you would eat and then wait to six hours later and

then eat and then fast for 18 hours this would be a really good pattern to follow

and then you can actually make it more strict over time depending on how you do

then what you can do is periodic prolong fasting to achieve additional health

benefits whether it's for your immune system because you have an autoimmune

problem or you just want to look younger with your skin or you want more brain

cells you want a better heart function better gut function or let's say you

have cancer and you want to improve that because one thing that fasting will do
