      hey all,
      ok, this is a big doubt i’ve had. 😕
      why do some people feel more hungrier than the other? is it just years of being used to eatin’ more or is there more biological to it ?
      advance thanks 😀
      HAPPY NEW YEAR TO ALL!!! 😀 😀 😀

      I’m guessing that it’s because of differences in the metabolic rates of different people.

      there’s a drug that advertised the ability to curb your hunger so a part of it is psychological/genetic.

      Isnt the feeling of hunger just contractions of your empty stomach?

      Hunger is your brain inducing a feeling in your stomach area telling you "hey, your body needs food." Different people have different brains. And the signals from the brain are slightly different.

      does this mean that hunger doesn’t depend upon the size of a person? are genetic and other stuff also involved?

      Actually, I’ve read that there’re two physiological processes that initiate hungry feelin’ which are:
      -Glucostatic theory
      gives you hungry feeling when the amount of glucose in blood below the normal level. It also initiates the deformation of glycogen in the liver.

      -Lipostatic theory
      gives uou hungry feeling when the amount of fat is below the normal level. (I think this is the later response because glucose digestion is a way ahead).

      more info, ask my lecturer… 😆

      Not just those two victor, there are more mechanisms. Like it was mentioned, even receptors in the stomach help determine wether we are hungry or not.
      The hunger "headquarters" is the hypothalamus by the way…

      why do some people feel more hungrier than the other?

      do not it quite unbelivable? did someone can be the other one so that he/she can feel the other feeling? I have question long time ago. how other human feel?, is it the same as me? how is if i become you? is it cool? how is feel?
      and i won’t be able to do it.

      we can not said that someone is more hunger than other, because it is in their mind, only. I mean, when two value of hunger from two people is quite similar. we can not know the who is the more hunger than another. the limit. too close, too difficult.

      it is biological evidence.
      hunger, as Mr. Mistery said, is controled by hypothalamus. i mean the stimulus goes to hypothalamus, not medula spinalis/oblongata or others.
      yap. it (stimulus) is caused by response in stomach. actually when it is empty it will send information to hypothamus that ‘no more food, need a food!’
      haha.. i make the example of word for the stimulus. yap, example can differ, but the point should the same.

      i wanted to ask a question. ok see my cousin she barely eats and exercises regularly but still she dosent lose weight. is it related to her metabolic rate? also i heard some ppl eat alot & dont gain any weight. is it due to the same reason?

      Yes, and yes. But be aware that if you don’t eat and exercise your body might develop a lack of vitamins and proteins

      The cause of hunger: low level of glucose, acidic stomach, less oxygen in brain 🙂

      low oxygen in brain causes hunger?

    • #37548
      Dr.Stein
      Participant

      Sure. That condition gives a feedback signal to nerves in brain that gives us a hungry feeling, and also gives an impulse to nervus vagus which one of its target is stomach. Then we decided to eat to get more energy, which will improve the blood circulation, which then will send more oxygen to brain.

      i have a question, when we are to much get oxygen in our brian we should get dizzy and maybe lost of control, right? not make our hunger felling dissapear, right?

      the explanation of Dr. Stein " Sure. That condition gives a feedback signal to nerves in brain that gives us a hungry feeling, and also gives an impulse to nervus vagus which one of its target is stomach. Then we decided to eat to get more energy, which will improve the blood circulation, which then will send more oxygen to brain. " is quite reasonable, but from that i’m will thinking that if the enough oxygen in brain not occurs, we will get hungry.
      hey why do not you make the detailed explanation. i mean the effect for those 3 factor on hunger felling.
      so that no one will thinking that if the three factor not occurs the hunger felling won’t arise in our head.

      hey, if we are lact of oxygen do not we will take a deep breath to get the oxygen? not eating some thing?

    • #38495

      Do you think that by taking a deep breath is enough to supply the oxygen? Even if it is enough, you need some energy to contract and relax your respiratory component. How can you provide energy if you do not have enough source? How can they be converted into energy if you do not have oxygen? This is a circle thing that you cannot split it into pieces.

      Why did not I make explanation in detail? Because none asked me to do, then I thought everyone knows about it. If I am not mistaken, some friends already describe it somewhere and I see that is enough. Why do not you try to explain it for us? 😉

      the source is our body self. if we do not body to be our source of energy -i.e.muscle, any living organ except bone and nerve cell- we won’t alive, right? that’s why docter give oxygen first before infuse because the passient have body.

      hey now you want me talking about energy.(T_T)

      quote :

      correct, but i think when human already has body the second step is air(oxygen)

      quote :

      back to hunger felling.

      okay i only detailed and modified your 3 answers above.

      first is no more food in our stomach, so that no new glucose is gained.
      then this make a low level of glucose that stimulate hypotamus to make "hunger" (there are sensor in our body, i cannot describe it for you because of my few knowlegge, but i can said this evidence has relation with our cell. when blood is lact of glucose the intersitium also lact of glucose. then our cell won’t runs properly, i mean it is not fast as normal. as the result the cell will known by sensory that it is not work properly (this is a complex mechanism, for futher info pls read book titled by receptor)nervous system is trying to solve this matter by "hunger".
      keyword are homeostasis, internal sensory, metabolism (maybe C-RNA are involve)). this is the most take part for arise hunger felling. but, when we are trying to hang on to not to eat something the felling,hunger, will dissapear for a few minutes. maybe we use our hormone to avoid the lact of glucose in our blood-glikogen in lever is converted to glucose.

      after several time HCl in our stomach hurt our self, so that the hunger felling increases.then if this goes for a long time we get maag.(the same as me) yes, that why we eat at periodical time. our stomach produce HCl at those time where is the time we often eat.

      about Oxygen, as your and my post above it is still needed to do aerobic metabolism. but, if Glucose is converted the CO2 will occurs. CO2 is can attract hemoglobin more good than oxygen, so our brain will lact of oxygen. you know that our nerveous cell is the most active so it has more mitocondria, because has many mitocondria the cell need more oxygen to do metabolic reaction-aerob. the suplay is from our breath.

      again we have body as our source of energy.

      so no food, lact of glucose is the main part that makes us fell hungry, so i think your answer is good but too much. about oxygen, when we are not hungry then we do not get any oxygen are we fell hungry? no, i think.lact of oxygen makes us breath not eat

      oh no…
      am my first post today makes you angry?
      i do not want any one angry… so i’m sorry.

      I am not sure I can interprete this paragraph well enough, maybe my English is too poor to understand this… I am not sure what you meant by "body" here… I hope I interprete it correctly.

      Well, if the source of energy is our body, why do you feel fatigue after exercising? and hungry as well? Why do you need a resting and eat? Our body is NOT the source of energy, our body is the machine. Food IS the source of energy and oxygen is the fuel. The food stored in our body is the other energy source. Maybe this is what you meant?

      Why is our body alive? Because our cells are living. How can they survive? Because of the metabolism. I am sure you know what metabolism is. Oxygen is always included everywhere, you may forget that when you ‘use’ your muscle, you expend the oxygen within your muscle, that’s the ‘fixed’ one, not the gas as we inhale. It will play a role in converting stored sugar (glycogen) into energy then you can contract and relax your muscle.

      Well, I want to highlight (I marked it in bold) some lines of yours, you have to provide me more arguments/answers for them because I am not sure what you are talking about. Here is my argument:

      "…when blood is lact of glucose the intersitium also lact of glucose…"
      —–> I have no idea

      "…when we are trying to hang on to not to eat something the felling,hunger, will dissapear for a few minutes. maybe we use our hormone to avoid the lact of glucose in our blood-glikogen in lever is converted to glucose
      —–> the disappearing hunger is because our body uses stored sugar for the source of energy by gycogenolysis or gluconeogenesis. Yes, hormones play role here…glucagon and adrenalin.

      "…CO2 is can attract hemoglobin more good than oxygen, so our brain will lact of oxygen…"
      —–> Only after Hb releasing O2 into cell. Hb will have a big affinity to O2 rather than CO2 only after releasing CO2 in alveoli.

      ‘…you know that our nerveous cell is the most active so it has more mitocondria, because has many mitocondria the cell need more oxygen to do metabolic reaction-aerob. the suplay is from our breath.
      —–> Really? I am not sure. Yes it is active cell, but not the most as far as I know.

      It’s ok, I am not angry at all. This is a nice discussion and not a debate. I appreciate your arguments, of course 🙂

      intersitium… the matrix of tissue. the intercellular medium which is used for transportation, i mean for sirculation. have you try google?or any dictionary? i think i spell it correctly, but … maybe not. so please take a dictionary. i have define it so i hope you do not misunderstand

      qoute.

      yes. that is why i said take a deep breath

      i’m so sure. my teacher said that, and i belief it.
      he said that the most active cell is nerve cells, then the second is muscle.

      oh.. maybe i’m take it too much, so i think you are angry to me. hehe..
