Through evolution, energy containing foods are conserved by the body for later use, and stored as the most energy concentrated molecule, fat. Excess energy-containing molecules are detected by their presence when all energy requirements are satisfied. How are excess energy-containing molecules detected, exactly? What exactly happens when all energy requirements are satisfied? I want to know the metabolic pathways, the hormonal signals, or whatever precise biological mechanism that detects the bodies energy status and responds by triggering fat storage or use. You aren't answering the question. You are generalising. I want the specifics. You don't need to write it all out, just point me to a url or another reference source that specifically lays it all out in detail. Fats are made by various chemical pathways (glucose to fat in the liver, for instance) and this excess fatty acid is stored in specialised tissues in various parts of the body. No ****. What is it about calories that triggers the fat storage? Conversely, by what specific mechanism does the body detect a dietary calorie deficit and by what mechanism does it then trigger fat burning. Fat is burned every minute of every day by the body. Stored energy is mobilised whenever there is s need for energy by the body that is not met by the liver's store, or circulating energetic molecules. You keep explaining it in very general terms. I want to know the specifics. How specifically does the body recognize that its energy requirements are not being met by the liver's store, or circulating energetic molecules? By osmosis? By fluke? By chaos theory? By ESP? By hormonal response? By sensory cells? By receptor molecules? By broadband antennae? Huh? What are the specific bio-chemical steps in both processes? I suggest you consult an elementary biochemical textbook to learn all about lipogenesis and lipolysis and other energy storing and mobilising pathways. They are quite straightforward and very well understood. Can you point me to one that explains how calories and specific quantitative caloric intake relate directly to lipogenesis and/or lipolysis. And more importantly how exactly is the body bio-chemically aware of its caloric deficit or excess and how exactly does it bio-chemically trigger lipogenesis and/or lipolysis. I've read quite a number of elementary biochemical textbooks and quite a few not so elementary and I've yet to see any clear, concise explanation of the direct and specific connection between caloric intake and the triggering of lipogenesis and/or lipolysis. By the way, I was looking in the archives, and see that all this has been fully explained to you at least several times previously. Why do you keep bringing it up? What are your motives here? You guys keep giving me the kind of general non-answers that you just BS'ed your way thru just now. It is obvious that if we accept the caloric theory of weight gain and loss, then the body has to have a way to recognize a state of either excess energy or a state of energy deficit. And then the body must take the excess energy and store it or conversely, when the body is in an energy deficit state, it must start using up fat. You just repeated the above using a little bit of scientific terminology. That is all that you have done. That is the only response, to this question, that I've seen in this ng. I keep asking the question and keep getting the same non-answers. What I asked for was not just a rote repetition of what must be obvious vis-a-vis the calorie theory. What I asked for was a detailed scientific explanation of the bio-chemical processes that does all of this. The metabolic pathways, the hormonal cascades, cells, molecules, etc. Not just what the body "must" do vis-a-vis calories, but the actual facts about what it does, and much more importantly, *specifically how* it does it. What is the specific bio-chemical mechanism that detects the bodies energy status at any given time? How does it detect the status, specifically? Once the energy status is determined, how exactly does this specific bio-chemical energy detection bio-mechanism then specifically trigger lipogenesis and/or lipolysis. The questions are so simple and fundamental, yet they have yet to be answered. TC snip previous stuff |

By molecular concentration, and enzymes ready to convert them to storage molecules. The law of mass action. Elementary chemistry. What exactly happens when all energy requirements are satisfied?

Concentrations of the molecules concerned. Try a simple biochem text. The body doesn't "measure" the energy content.

What is it about calories that triggers the fat storage? It's fatty acid concentration that "triggers" fat storage. What do calories have to do with it?

I want to know the specifics. How specifically does the body recognize that its energy requirements are not being met by the liver's store, or circulating energetic molecules? Concentrfations. You seem to be having some basic conceptual difficulties. By osmosis? This aids some molecules to pass certain barriers to free diffusion. By fluke? No, when the concentration on one side of a chemical reaction is high, the reaction moves to the other side. You have studied a little basic chemistry, I hope. By chaos theory? By ESP? Yet more lack of understanding? And you have had it explained before? I'm beginning to wonder about your motives. By hormonal response? Hormones will be involved in facilitating some reaction pathways. By sensory cells? Yes, these can sometimes permit some chemical transactions to go ahead (feedback loops).

What are the specific bio-chemical steps in both processes? I suggest you consult an elementary biochemical textbook to learn all about lipogenesis and lipolysis and other energy storing and mobilising pathways. They are quite straightforward and very well understood. Can you point me to one that explains how calories and specific quantitative caloric intake relate directly to lipogenesis and/or lipolysis. I've said several times, any elementary biochem text. As I've tried to explain, molecular concentrations drive reactions. The molecular species determines exactly how much energy is contained within the bonds of that molecule. And more importantly how exactly is the body bio-chemically aware of its caloric deficit or excess and how exactly does it bio-chemically trigger lipogenesis and/or lipolysis. You seem to have a misconception of just what energy is. Energy is needed by the body to carry out many of its functions. It all originally comes from the Sun. Every molecule has a certain energy associated with its chemical bonds. When you break a bond, an exact amount of energy is transacted. Similarly when you create a bond. The body does not "measure" energy, it "measures" molecular concentrations. I've read quite a number of elementary biochemical textbooks and quite a few not so elementary and I've yet to see any clear, concise explanation of the direct and specific connection between caloric intake and the triggering of lipogenesis and/or lipolysis. Perhaps you have missed it because of this confusionn of what energy is. Get that straight, and I think you might be OK.

You guys keep giving me the kind of general non-answers that you just BS'ed your way thru just now. Or you keep having problems understanding plain English. I've seen some folks have actually pointed you to specific references for all of this. I've yet to see a biochem text that does not deal with this topic. It is basic. It is obvious that if we accept the caloric theory of weight gain and loss, then the body has to have a way to recognize a state of either excess energy or a state of energy deficit. See above. You have quite a problem there. Get your enegy concept right and you should be well on the way. And then the body must take the excess energy and store it or conversely, when the body is in an energy deficit state, it must start using up fat. Stop thinking of energy and think of particular molecules. Then you can look them up to see how many calories they have available when converted to something else. You just repeated the above using a little bit of scientific terminology. Yes, you had better get used to some scientific terminology. It makes understandig so much easier. Try writing down some simple definitions and refer to them as you go. That is all that you have done. That is the only response, to this question, that I've seen in this ng. I keep asking the question and keep getting the same non-answers. As I said. Leave the energy out for now, and just think of molecules. You can introduce the energy later when you are not so confused. What I asked for was not just a rote repetition of what must be obvious vis-a-vis the calorie theory. What I asked for was a detailed scientific explanation of the bio-chemical processes that does all of this. I've told you. basically it is detection of molecular concentration via simple chemical principles. The metabolic pathways, the hormonal cascades, cells, molecules, etc. Not just what the body "must" do vis-a-vis calories, but the actual facts about what it does, and much more importantly, *specifically how* it does it. Far too complex to go into here, but all texts I've seen deal with it well. What is the specific bio-chemical mechanism that detects the bodies energy status at any given time? Molecular concentration. The body can't actually measure the energy content of a molecule, it can only do what it is programmed to do with various molecules. When it "needs" energy, it does things with particular molecules that just happen to contain a lot of energy. How does it detect the status, specifically? Molecular concentration. Gee, you ask this question a lot. I sense your frustration. Once the energy status is determined, how exactly does this specific bio-chemical energy detection bio-mechanism then specifically trigger lipogenesis and/or lipolysis. See above. The questions are so simple and fundamental, yet they have yet to be answered. No, the answers given have yet to be understtood by you, I'm afraid |

Fats are made by various chemical pathways (glucose to fat in the liver, for instance) and this excess fatty acid is stored in specialised tissues in various parts of the body. No ****. What is it about calories that triggers the fat storage? It's fatty acid concentration that "triggers" fat storage. What do calories have to do with it? Calories are merely a measure of the energy contained in the chemical bonds of these molecules. This energy can be utilised for many of the body's energy reqiuiring activities -- muscular activity and the like. Conversely, by what specific mechanism does the body detect a dietary calorie deficit and by what mechanism does it then trigger fat burning. Fat is burned every minute of every day by the body. Stored energy is mobilised whenever there is s need for energy by the body that is not met by the liver's store, or circulating energetic molecules. You keep explaining it in very general terms. I want to know the specifics. How specifically does the body recognize that its energy requirements are not being met by the liver's store, or circulating energetic molecules? Concentrfations. You seem to be having some basic conceptual difficulties. By osmosis? This aids some molecules to pass certain barriers to free diffusion. By fluke? No, when the concentration on one side of a chemical reaction is high, the reaction moves to the other side. You have studied a little basic chemistry, I hope. By chaos theory? By ESP? Yet more lack of understanding? And you have had it explained before? I'm beginning to wonder about your motives. By hormonal response? Hormones will be involved in facilitating some reaction pathways. By sensory cells? Yes, these can sometimes permit some chemical transactions to go ahead (feedback loops). Can't think of any particular examples at the present time. By receptor molecules? Not sure what you mean here. By broadband antennae? Huh? Are you trying to be dense? You seem to be succeeding. What are the specific bio-chemical steps in both processes? I suggest you consult an elementary biochemical textbook to learn all about lipogenesis and lipolysis and other energy storing and mobilising pathways. They are quite straightforward and very well understood. Can you point me to one that explains how calories and specific quantitative caloric intake relate directly to lipogenesis and/or lipolysis. I've said several times, any elementary biochem text. As I've tried to explain, molecular concentrations drive reactions. The molecular species determines exactly how much energy is contained within the bonds of that molecule. And more importantly how exactly is the body bio-chemically aware of its caloric deficit or excess and how exactly does it bio-chemically trigger lipogenesis and/or lipolysis. You seem to have a misconception of just what energy is. Energy is needed by the body to carry out many of its functions. It all originally comes from the Sun. Every molecule has a certain energy associated with its chemical bonds. When you break a bond, an exact amount of energy is transacted. Similarly when you create a bond. The body does not "measure" energy, it "measures" molecular concentrations. I've read quite a number of elementary biochemical textbooks and quite a few not so elementary and I've yet to see any clear, concise explanation of the direct and specific connection between caloric intake and the triggering of lipogenesis and/or lipolysis. Perhaps you have missed it because of this confusionn of what energy is. Get that straight, and I think you might be OK. By the way, I was looking in the archives, and see that all this has been fully explained to you at least several times previously. Why do you keep bringing it up? What are your motives here? You guys keep giving me the kind of general non-answers that you just BS'ed your way thru just now. Or you keep having problems understanding plain English. I've seen some folks have actually pointed you to specific references for all of this. I've yet to see a biochem text that does not deal with this topic. It is basic. It is obvious that if we accept the caloric theory of weight gain and loss, then the body has to have a way to recognize a state of either excess energy or a state of energy deficit. See above. You have quite a problem there. Get your enegy concept right and you should be well on the way. And then the body must take the excess energy and store it or conversely, when the body is in an energy deficit state, it must start using up fat. Stop thinking of energy and think of particular molecules. Then you can look them up to see how many calories they have available when converted to something else. You just repeated the above using a little bit of scientific terminology. Yes, you had better get used to some scientific terminology. It makes understandig so much easier. Try writing down some simple definitions and refer to them as you go. That is all that you have done. That is the only response, to this question, that I've seen in this ng. I keep asking the question and keep getting the same non-answers. As I said. Leave the energy out for now, and just think of molecules. You can introduce the energy later when you are not so confused. What I asked for was not just a rote repetition of what must be obvious vis-a-vis the calorie theory. What I asked for was a detailed scientific explanation of the bio-chemical processes that does all of this. I've told you. basically it is detection of molecular concentration via simple chemical principles. The metabolic pathways, the hormonal cascades, cells, molecules, etc. Not just what the body "must" do vis-a-vis calories, but the actual facts about what it does, and much more importantly, *specifically how* it does it. Far too complex to go into here, but all texts I've seen deal with it well. What is the specific bio-chemical mechanism that detects the bodies energy status at any given time? Molecular concentration. The body can't actually measure the energy content of a molecule, it can only do what it is programmed to do with various molecules. When it "needs" energy, it does things with particular molecules that just happen to contain a lot of energy. How does it detect the status, specifically? Molecular concentration. Gee, you ask this question a lot. I sense your frustration. Once the energy status is determined, how exactly does this specific bio-chemical energy detection bio-mechanism then specifically trigger lipogenesis and/or lipolysis. See above. The questions are so simple and fundamental, yet they have yet to be answered. No, the answers given have yet to be understtood by you, I'm afraid |
