What is Hunger?

What is Hunger?


Hello and welcome to NerdSanctum, today we
will be taking about what hunger really is, how it’s influenced, and what we can do
about it. From a biological point of view the sensation
of hunger is really a balance of hormones and chemicals. This balance is has two sides,
hunger and satiety, which is the feeling of fully satisfying a desire or appetite. Both
of these sides operate in the same part of the brain. Hunger is controlled by the lateral hypothalamus,
every time that part of the brain is stimulated it causes you to feel hunger; in-fact if you
cut or damage the lateral hypothalamus you would NEVER feel hungry ever again. Satiety is controlled by the ventromedial
hypothalamus and it works similarly, every time that part of the brain is stimulated
it causes you to feel full; and if you cut or damage it you would NEVER feel full ever
again. So now that we understand this balance let’s
look at the causes of hunger. Hunger can be caused by a variety of factors, both environmental
and physiological. Some examples of environmental causes are: friends inviting you to a meal,
being bored or stressed, smelling food, or forgetting the last time you ate. While some
physiological examples would be needing to intake more energy, having unbalanced hormones,
genetic causes, or damage to parts of your body that regulate hunger. With these categories in mind, we see environmental
causes are usually a craving, a desire to eat to fulfill needs other than hunger or
are really a WANT. While physiological causes are due to a NEED. Managing environmental causes or WANTS is
mostly an act of self-control; but that decision can be hard, because who doesn’t love food
right? Especially since our brain has evolved to love large and quick sources or energy
like sugar or proteins which are pretty much in every food product that was designed by
an entire industry to work off our desires to make money. Managing physiological causes or NEEDS can
be difficult too. There’s a thing called Set-Point theory, which is a genetically programmed
weight range that a metabolic system tries to maintain. This means that your hypothalamus
turns on and off your hunger impulses and regulates your metabolic rate in-order to
change your weight to something it defines as optimal. Some people find this hard to
accept, but it’s just like any other pre-programmed attribute like height, eye color, or hair
color. So now that we understand what hunger is,
and what causes and influences it; is there anything we can do about it? Yes, there are
plenty of small things that people can do that help meet their physiological NEEDS while
satisfying their environmental WANTS. Some things would be eating smaller meals
more frequently with all nutrition categories. This way you never get too hungry and binge
and you get all the inputs your body needs to function distributed evenly throughout
the day to feel energetic and not drowsy. Nutrient balancing is better than calorie
counting! Drink liquids and eat filling appetizers like
soup or salad. This way your body naturally hits it’s set-point quicker without having
to consume more energy dense foods that could leave excess energy. Then there are quirky tips like use small
plates, keep a journal of what you eat, and eat in a room away from the food so you have
to get up. All these are small things that keep you aware about your habits and limit
incentives. I’m obviously not a health expert, but to me the rule of thumb is simply be confident
and do what makes you happy in moderation. If you deprive yourself of happiness for too
long you’ll end up crashing or binging, and that is what really leads to problems. Anyways that’s all I have for today, I’d
like to hear if you have any thoughts, stories, or tips down in the comments below and as
always thanks for watching and until next time have a good day.

  1. My scinece teacher told us Monday that quantum physics is boring because it doesn't make sense to her. I'm like (facepalm)

  2. Great to see you again, Devon! Its been a while, I was getting a bit concerned haha. Very interesting video, I liked how you used the pictures to emphasize your points and you have a very nice voice to listen to.
    How has university been? Everything okay over there? Good job, man, I hope to see more from you in the future ๐Ÿ™‚
    (By the way, i used to be pomegranatesareokay)

  3. I used to watch you on Younow, glad to see you making videos again, they make my brain smarter. ย LOL! ย ๐Ÿ˜€ ย 

  4. Nice video sir ๐Ÿ™‚ i love your explaining technique , speaking and voice , you are nearly perfect , thanks for that , btw nice to meet you dear devon ๐Ÿ™‚

  5. เฒ _เฒ  We should implement PUNISHMENT system for Nerd when he doesn't upload according to scheduleย เฒ _เฒ ย เฒ _เฒ ย เฒ _เฒ ย 

  6. Food for thought. I paused and no longer found the desire to watch the rest of your video because your audio quality is abysmal. A $75 microphone investment with a bit of physical reverb deterrents would help out your channel.

  7. I just came across u, and i am speechless thank u so much, u might be able to finn a plan to help people that have a weight problem. Thanks for sharing.

  8. thank you!!! you are good! ย you covered everything, so clear and concise. how young are you, by the way? thanks.

  9. Is it weird or unhealthy that I don't get hungry? I can go 2 weeks without eating and do not get a bit hungry. Should I talk to a doctor lol

  10. Thanks for the video nerd ๐Ÿ™‚
    been having a rough day forgetting things, because I ate breakfast too lat into the morning its really messed up my brains interpretation of how much energy it has ready to use. Anyway I didn't feel so rationally about food until this video popped up, now no longer panicked, just doing what I can to help myself.
    Its surprising how when we ignore the tools we have to combat hunger and other issues, all we can do is panick. anyho, part of that is all a mind game! Thanks for the video

  11. i hate this piece of chemicals arranged specialy to make a multicellular organism(body) i constanly need to put organic edible molecules so it can function

  12. Excellent Video!! Congratulations..ย  I wonder if you can help how I can neutralize the hunger whenever someone offer me food .. I never remember nor think nor feel hungry… unless morning.ย ย  at noon and at night.ย  by out of this range my wife always offer me something to eatย even I saying no… it activates my hunger and itย disturb my concentration in other things. tks!

  13. Son, everything you said was good, but we did not "evolve" brains.ย  Your thalamus, hypothalamus, visual cortex, cerebral cortex are the result of design…….not time nature and chance.ย ย  I could not convince you the chair you are sitting on happened because lighting hit a tree, a tornado swept up the tree and over many years you have a chair….someone intelligent first thought of a chair, then their mind thought up the design then someone smart built it.ย  your brain is more complex than your chair, it was first conceived, designed then built.God and science are best friends…evolutionism is anti-science.Thank you.

  14. thanks for the info. subbed and Favorited. I'm doing research on hunger for personal reasons. Anyways, you don't have to but it would be cool to include one or two sources in the description of your information to read more upon it.

  16. New topic suggestion/request:
    I understand human beings are biologically capable and actually rather well-designed to periodically water fast when needed (illness, injury, lack of resources) or on-purpose (for health or spiritual reasons) for long periods of time. I've read that locked away in our bodies are all kinds of rich stores of nutrition (fats, minerals), that we access & use whenever we fast (or go through famine).

    Today I came here hoping to learn two things:
    1. During long water fasts, how long should it take until an average human body would experience true legitimate biological hunger?

    And, most important to me, I wonder
    2. What exactly are the sensations of true hunger, and exactly what biological processes would that true hunger be coming from?

    Care to go into this with a new video?

  17. My brother, just will not eat anything, and he says that he's full at all times, and he thinks his food is going to the wrong place, and it's been this way for 2 weeks. He will only eat little bits of egg every morning, like a mouse. please help :)!

  18. i like the way you can explain a subject clearly and in laymans terms in such a short time, you should do loads more!

  19. I dont really get hungry at all but i know i cant not eat… but everytime i do eat i feel SOOOO full that it kinda hurts even if its a little.

  20. Im.having the worse side effects from.anti biotics…its mking me ravenous continuosly to the point i cant even stand. When iv ate..thr hunger will carry on but then il.puke the food out. N hungrry again. Gna stop the anti biotivs now

  21. I need my thalamus to be taken out of my brain…. Oh the joy of never being hungry… ๐Ÿ˜Œ

  22. Hi Devon,
    thanks for so much info in less. It was efficient. Just a cool tip for you. Try to look into camera while you speak: I know that to be quick and comprehensive, you had to read it from somewhere, and you did a pretty good job in compensating that with good articulation which made it look like more nature. Still, I would like to suggest to put the reading material above the camera.. it would look more natural that way. Best regards,
    Syed

  23. Good video, that is sorta right coupled with some really bad advice. Hunger is a hormone driven process that stimulates a primal drive to consume. All cells in the body contribute to the hormone balance. There are different types of satiety. Every step of the process has hormone(s) that signals to the brain whether you are fed or not. What you eat; when you eat; how you eat; how much you eat; what you absorb into the system; what gets rejected; (and most importantly) did the cells with the "issue" get what they needed. All this and more plays a role in this drive. Simply eating is not enough to fulfill it.

    When you feel hunger your body is telling you that you need something. Usually it is something that that the body can't produce itself or something it produces to slow. The most common reason for hunger is a vitamin or protein deficiency. Let's make this perfectly clear, starvation is a condition of severe malnutrition while hunger is a drive to prevent starvation.

    The most common misconception in nutrition is that macro nutrients are required on a regular basis for the body to function correctly. This is false. The energy that your body uses is entirely manufactured by the cells in your body (unless you consume raw ATP or glucagon). Your body manufactures these chemicals out of combining oxygen that you breathe with triglycerides produced by your liver. As the cells break down the triglycerides, they ultimately turn into many chemicals but the most abundant are CO2 and H20. The triglycerides are produced by taking the broken down macro nutrients and combining them into long chains of fat which is then STORED in adipose tissue until needed. Vitamins are stored in adipose tissue too.

    If you simply eat every few hours, you will be telling your body to store that energy with the hormone called insulin. While energy is being stored over the hours after you eat, your body will not be able to access the nutrients contained in those "fat" cells, which can cause you to have, say for instance vitamin B12 in your fat cells that can't be accessed. Which will cause you to hunger if you didn't eat enough vitamin B12 in the last meal. In a state like that, it is possible to become malnourished while eating 5000 calories. Which in turn will force you to eat more calories. A viscous destructive cycle.

    Eating a well balanced diet, only at the times you are hungry is recommended. If you ate the right stuff, you won't be hungry for 10+ hours. If you are hungry 2 hours after a meal, you should now know, you ate the wrong damn thing and there will be a terrible price to pay if you don't listen to your body. Eating any old junk according to the clock will do enormous damage to your body, and will cripple your system (based on genetics) sometime between the ages of 20-50 years old. I am talking about irreversible damage that happened over years of your body ripping itself apart chemically trying to make ends meet.

    You have been warned. Eat your meat, eat your greens, cut out the snacks, drink watertea. Very little deviation from those rules will help your future health immeasurably.

  24. But it is perfectly possible to live without a stomach so how do you get hungry? DONT JUST LIKE MY COMMENT GIVE ME AN ANSWER
