What If You Stopped Eating?

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 you can click the screen or use the
links in the description it really only takes a few moments and subscribe to our weekly science
