What If You Stopped Eating?

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

  1. So if i will take Vitamins after 3 days the body will still born fat?(spironila for protian,b12,vI,d)

  2. Ketosis after 6 hours? Not really, if you exercise and deplete your glycogen with high intensity workout, maybe you'll need 12 to 24 hours. if you're inactive, you may need up to 72 hours just to ENTER ketosis. And fasting IMPROVES cognitive functions, attention span and general alertness. Otherwise, our ancestors would be killed in a matter of days!

  3. When he says it can shut down the menstrual cycle, he’s acting like that’s a bad thing lmao, I hate my period

  4. When i had anorexia the only thing that I did was to drink water and chew gum it tricks your mind.
    It is a horrible nightmare
    (Sorry for my bad English)

  5. Who said you couldn't drink water while not eating for 2-3 weeks, I'd think you'd live one more week longer

  6. I try not to eat for a weeks but the problem is that my recommendations is all about foods😂😂😂

  7. Ok, so one time, I was starving myself at school, and i was with a friend, and I was just digging through my and his backpack for food. My mind is like “EAT NOW”

  8. for some reason when i dont eat after like a day i become nauseated then i dont wanna eat so its like make up your mind body are hungry or not

  9. Any one know how not to eat but also not die and be ok like can I eat a few crackers and have that feed me enough to keep me alive as I just want to be thin not dead or at least not yet

  10. Starvation can not cause death in three weeks, I HAVE HAD AN EATING DISORDER FOR OVER A YEAR AND I HAVE STILL NOT DIED.

  11. its been 7 hours since ive eatin and im doing a challenge where i only eat gum and drink water for 3 days wish me luck
    (update) so this challenge is very hard and i dont recommend it, keep in mind i stopped this challenge.

  12. Wait is this why I haven't started my period yet? Because I'm so skinny you can see my bones and I don't eat? Dang..

  13. What if you only eat 100 cals a day, I dont eat my lunch at school only a bit and throw it away. I feel bad wasting food

  14. I like food about a week ago now I wanna throw up because I hate it I’m not going to school today bc I threw up but I’m hungry ?anyone?

  15. Im just watching this because I was watching Mukbang at midnight and Im hungry. I dont wanna go downstairs😂😭🍔

  16. Still, I'll have to eat something when my parents call me for a meal.
    And when you're really hungry, it's easy to slip and overeat (the worst thing that can happen when you're too hungry)

  17. Came here to see how often I should eat. I wanna eat the minimum possible, so I only eat once a day, I think I’m getting at least 750 cals but I do want to lose 20 pounds in the next month. I’m afraid I’ll try to stop eating altogether so I came here to see where I should draw the line, so like every other day at the least. Don’t do this though, I just have no appetite recently. If you have an eating disorder I would get help. I used to kinda binge eat.

  18. Me, who skips lunch to lose weight: “… well on the bright side, i dON’t hAve tO DEaL WitH mY PeRioD yAy”
    (And before you screech to me about it, I KNOWWWW you can get sick and not have children from not having your period so CALM DOWN you unhumourous swines ;-;)

  19. My friend was anorexic and she didn’t die im not happy she starved herself. Tho but I can’t be talking bc i try to do it she did it for months

  20. My friend doesn't eat as much she needs to .. its about 6 months she just sit on the laptop all the day and have one meal which is not probably so healthy and snack very rarely .. she just slept throughout 12 hours and have this very bad habit and also of dehydration,, yesterday I asked her in dm and she said she was in hospital (she wasn't attending classes so I asked) she had many tests including blood tests and other, so pleez don't try to fast on unhealthy thing and keep urself away from food .. u will not die but will face severe issues … u r precious to so many people so keep urself hydrated and full 💞💞💞

  21. If u lose your period it means your either pregnant or anorexic. Teens neither is good for ya so…. Think mature and healthy💜

  22. I starved myself few days ago, because i want to become thin. Now I keep an extremely low calorie intake and I went down 5-6 kg in just a week

  23. My bf broke up w me yesterday. Now I havent eaten in about 27.5 hours. Im not even 100lbs and Ive spent about 6 of those hours crying so I dont think the small glass of water I drank counts…

    Cant wait to die

  24. This is partial information. The record for fasting is nearly 400 days. Muscle breakdown is not that drastic. Obviously if you're underweight you shouldn't fast. Most people aren't underweight.

  25. I can’t eat sometimes because the thought of food makes me physically sick. I’m not overweight but I wish I was thin, I’m scared that if I don’t eat I’ll die… that’s not what I want. I know I’m only 14yrs old but I rlly want to be toned and skinny, I’d probably feel confident and maybe go swimming more often. My weight holds me back a lot… I currently weight the average but my stomach and my legs feel fatty, which makes me super insecure. I always wear my jumper during ballet because I’m scared I might look fat…. And for some people this may sound stupid but I don’t know whether i have an eating disorder or what? I don’t eat much anyways besides being vegetarian… I also can go for like two days without eating and I’d feel fine, except I tend to get dizzy easily but that’s even when I eat. I workout twice a day, everyday… I just get tierd easily and it makes exercise harder.

    I just want to be skinny,
    I don’t want to die tho…

    What do I do?

  26. Me: ~Watches video~
    Ana in my head: YOU HEAR THAT!? IT WILL MAKE YOUR PERIOD STOP! YOUR ON YOUR PERIOD! YOU NEED TO STAVE AGAIN YOUR EATING TO MUCH! DO YOU KNOW WHAT THOSE CALORIES DID TO YOU?! STARVE DEMON STARVE!
    Me: WHAT DID I DO ANA? SHUT THE F UP!
    Ana: OK FINE CRY YOURSELF TO SLEEP OR WORKOUT!
    Me: Fine bish!😒
