Food is a favorite pastime for many which is convenient because we needed to
live but what would happen to you in your body if you were to completely stop
eating food right now in the first six hours all is fairly normal your body
begins to break down glycogen which stores energy in your body into glucose
which are cells use as fuel around 25% of energy generated this way is used for
your brain alone while the rest goes some muscle tissue and red blood cells
but after about six hours this method of energy production halts as the glycogen
stores deplete which can lead to the notorious Hangry or hungry and angry
feeling that many of us know too well at this point your body at his estate
called ketosis as it begins to fast or starve because there's very little
glucose in your blood your body must begin to break down fat for energy this
fat is in turn broken down into fatty acids however your brain can't use long
chain fatty acids which is a problem because there's no more glucose and the
faster too large to cross the blood brain barrier your brain changes modes
and begins to use ketone bodies for energy which are short-changing
relatives of fatty acids this works for the time being but ultimately only 75%
of the brain's energy requirements can come from ketones it still needs glucose
which means your cognitive functioning becomes impaired now it's important to
mention that you don't have to be starving to be in ketosis many people
enter this phase if they're on a low carb diet or professional athletes who
use all their carbs for an extended period of time like marathon runners
will be in this state as well however beyond 72 hours not only will your mood
and energy suffer but your brain will start to break down your body's own
protein the proteins release amino acids which can be converted into glucose
which is great news for your brain but bad news for your body basically your
body is cannibalizing itself by destroying your muscle mass
in women under nutrition often shut down the menstrual cycle as the body tries to
reduce energy expenditure bone density diminishes and both men and women may
experience loss of libido within a few weeks the body's immune system will be
so we can without any vitamins or minerals that many will die from disease
otherwise it will continue to use up all energy sources in till there was no
glucose fat tissue or muscle man left one of the more common causes of death
is cardiac arrhythmia or heart attack due to the tissue degradation in the
heart diaphragm and body this is fairly common in those suffering from anorexia
of course the body experiences severe organ failure all around
starvation can lead to death in a short as three weeks or up to seventy days as
documented during the Irish hunger strikes in 1981 though the duration of
survival is greatly influenced by how hydrated you are and the amount of fat
reserves your body has which some ways is incredible that the body can sustain
for so long with no food and get approximately seven hundred and ninety
five million people around the world have to deal with this reality the good
news is that the seven richest countries have pledged to lift 500 million people
out of hunger and malnutrition by 2030 but we need to hold them accountable
we're working with an organization called global citizen to do just that
and here's a really easy way that you can help out to buy sharing this video
and then heading to the global citizen website forum here you'll be adding her
voice to an important educational movement towards ending hunger worldwide
