Guest guest Posted August 7, 2006 Report Share Posted August 7, 2006 I am not proposing that we break the laws of thermodynamics. I am proposing that not all people can break chemical bonds equally. Just because energy resides in the chemical bonds in the food we eat, does not mean that all people have equal means to cleave those bonds and harvest the energy equally. Pushing reactions to activation, often requires special enzymes. Not all people have the same enzymes. Not all people will process food identically, as you must be aware, considering the many enzymatic diseases we know about. I don't mind residing in a different galaxy than you, or having different opinions and understandings. In fact, I prefer it. And I have no interest in changing your perspective. I do have an interest in challenging potentially erroneous conclusions, bigotry, and questionable scientific practice. In this vein, I am happy to send along a few studies. The studies below were not designed to meet your criteriae, but they do support some potentially different causes of obesity than just simple overeating.. (Aside, there is a difference between eating high fructose corn syrup, or as has often been discussed here, fruit juice, and eating unprocessed fruit. But that has been well discussed before.) And, you have misattributed my post. I would ask that you read what I said more carefully before you assert that I am giving anyone " excuses " . Or perhaps you were not referring to what I said, after all, as it does not fit. In fact, I wrote of people striving for personal excellence, and they are not obese people. They are people who find it exceptionally challenging to avoid weight gain. I apologize if that was not as plain, in my writing, as it seems to me, to be. Variables are variables and I think it is unscientific for anyone to dismiss known variabilities in the discussion of obesity. Citing variability in tendency to gain and retain weight is not making excuses. It is reflecting fact. And what is this us (thin) versus them (obese) attitude? Many people on this list do, or have struggled with obesity. The very fact they are on this list argues against your portrayal. If we treat all people with respect, we might be more able to just enjoy one another's company. And finally, I don't frequent fast food places, but relate what I saw mostly in restaurants in Quebec and Montreal, and the people involved were slender, as they ate their piles of fries smothered with cheese and gravy with large servings of cole slaw. It may be that because I am in an athletic field, most of my colleagues tend to be slim, but nonetheless, it is a faithful representation. citations follow Sincerely, Kayce http://diabetes.niddk.nih.gov/dm/pubs/pima/obesity/obesity.htm http://query.nytimes.com/gst/fullpage.html?sec=health & res=940DE4DF1739F936A15751\ C0A96E948260 http://www.obesityresearch.org/cgi/content/abstract/5/4/341 http://ajpendo.physiology.org/cgi/content/full/275/5/E830 not over 30, but worth note http://jcem.endojournals.org/cgi/content/abstract/85/3/1087 http://www.obesityresearch.org/cgi/content/full/12/7/1060 http://diabetes.diabetesjournals.org/cgi/content/full/52/6/1403 http://hmg.oxfordjournals.org/cgi/content/abstract/10/14/1491?ijkey=6d945a0117aa\ 9fa8ffdd03b1dd92bc96109efea3 & keytype2=tf_ipsecsha http://www.eje-online.org/cgi/content/abstract/155/2/331 From: " Rodney " <perspect1111@...> Reply- Subject: [ ] Re: You Cant Fix What You Deny Date: Sun, 06 Aug 2006 21:58:59 -0000 Hi Kayce: Well it is clear to me that you and I reside in different galaxies. Either that or parallel universes : ^ ))) I will be more than happy to be persuaded to your point of view about the origins of obesity, but only when I see persuasive evidence to support it. (I list a few examples later, of the kind of evidence I would need to see.) I *have* seen studies posted here which indicate that the metabolic rates of obese people are not lower than the average. Indeed, they are usually found to be higher, no doubt because they have greater LBM, in addition to higher fat reserves. I have also very recently seen reference (in the latest issue of the Preventdisease.com email newsletter) to a study which showed that when obese individuals, unable to lose weight and claiming to be eating a low calorie diet, have their BMR measured, it is clear that they are burning off far more calories than they claim to be eating. Something doesn't compute. Right? We all know what, I think. In addition a study was posted here showing that when overweight people are escorted throughout the day, and their food intake recorded and reviewed at the end of the study period, it is found that the records the subjects themselves kept, had under-recorded what they had actually eaten by a substantial margin - I recall 40% was the number. It will be found in the archives. I believe it was posted by Jeff Novick, quite some time back. These suggest denial to me. ----------------------------------------------- We are all aware of the laws of thermodynamics. We all presumably understand that a reduction in caloric intake below caloric expenditure must reduce body weight - no exceptions. I have checked data posted here by Dennis de Jarnette as he lost weight starting from a BMI of ~35 and had his BF% accurately measured. I have also checked my own case, losing weight at BMIs in the 21 to 25 range (but for me using the, not totally accurate, US Navy BF% calculation method). In each case the weight lost has been composed of 60% to 70% fat, and 30% to 40% LBM. Granted, this is a very limited data set, but I have seen nothing elsewhere of an empirical nature that suggests anything other than that if obese people ate a lot less than they do, they would eventually return to a healthy weight. If there are studies showing data different from the above they ought to be posted. It is also worth noting that while about half the obese community and their advocates like to assert that it is next to impossible to lose weight ( " so don't bother even trying " ?) the other half have a quite different, and entirely contradictory, complaint. The complaint of this other group is NOT that they cannot lose weight. Their complaint is that after losing a considerable amount of weight through restriction of food intake, and having achieved some targeted lower weight, they quickly return to their original weight, or higher, after resuming their old eating habits. Is this not a clear acknowledgment that obese people can and do lose sizeable amounts of weight if/when they reduce food intake? Rather, the issue appears to be that they are unable to maintain a reduced caloric intake once their target has been reached. So I submit there is no serious dispute, even among the obese, that restriction of calories is all that is required to achieve an appropriate weight. ------------------------------------------- However, the above said, I would take a very keen interest, and am certainly open-minded to changing my view, if someone can post studies which demonstrate any of the following: A) That thirty or more obese people, when put on a carefully controlled, RDA-adequate, 1200 calorie, metabolic ward, study failed to lose weight, or That thirty or more obese people, when they put on a metabolic ward study with 1200 RDA-adequate calories, lost only LBM, while fully retaining, or increasing, their previous body fat reserves, or C) Thirty or more obese people, while consuming a carefully measured 1200 calories, and burning off a carefully measured 1200 calories daily, showed a sustained increase in weight. These are the types of study that seem to me are required to substantiate the kinds of arguments you and others put forward. Can you post any such studies? Or other (very carefully measured) studies which suggest conclusions similar to those above? If you were to do this I would take a serious look at them. But do not bother to post them if the measure used for caloric intake is what the subjects SAY they are eating. Or if the quantity of exercise assumed is the amount they CLAIM to be doing. ------------------------------------------ My beliefs about the reason for the emergence of an obesity epidemic in western countries starting approximately in the 1960s, is too long and, not the least, too controversial, to go into it here. But it has nothing to do with supposed violations of the Laws of Thermodynamics (in all the various disguises these arguments are presented), and it has everything to do with the reasons for the failure to restrict food intake. ------------------------------------------ We are all familiar with the list of excuses: " it isn't you, it is your genes " ; or " it isn't you, its something your mother ate during pregnancy " ; or " it isn't you, its high fructose corn syrup " (while many of the same people who think fructose is the near lethal also think fruit, which contains plenty of it, is just wonderful); or " it isn't you, it is the junk food corporations who are forcing you to eat their products " [no doubt plenty more excuses can be added to this list]. Then, of course, there are the people who will advise the obese that: " it is impossible to lose weight so do not even bother trying. " But perhaps most important point here may be the destructive effect that the promotion of these excuses, and the giving of that kind of advice, has on the very people who most need to restrict their food intake. They are a powerful demotivator that will only serve to distract them from getting around to doing what they urgently need to do to protect their health. Not helpful, imo. Rodney. PS: I was interested to hear your anecdote about canadians eating huge meals and staying slim. I doubt you will find anyone resident in Canada agreeing with your sentiments. I have lived in Canada for a very long time and almost every day I encounter people who look to be a mile wide. I very much doubt the average circumference in Canada is materially different from that in the United States. Next time you are in Canada try going to the food court in any canadian shopping mall, or to a Harvey's hamburger chain outlet - or Mc's or Burger King. You will see plenty of obese people these places. And almost always, if you take the trouble to observe, you will find a direct correlation between the size of the individual and the amount of food they order. By one route of logic one might have hoped it would be the other way around. By another, of course, it makes perfect sense. I have often thought of saying to some of these people: " Look, you really don't need to eat for an entire month do you? So what are you doing in here? " So far I have been able to restrain myself. And as for your point about: " Rodney's doctor needs to refer patients to competent coaches " .............. what, please, does this tell you about these people? ....... that, you seem to be saying, they cannot simply take and act on their doctor's straightforward advice about how to fix an obviously serious health problem? You are telling us that they need to be *coached* about how to follow simple advice? As I said, we must be from different galaxies.

Guest guest Posted August 7, 2006 Report Share Posted August 7, 2006 Yes it does: " These studies, carried out with the help of the Pima Indians, have shown that before gaining weight, overweight people have a slower metabolic rate compared to people of the same weight. " So it IS their hormones and their genes AND the food they put into their mouths, and the exercise. However, they start out with a genetic predisposition which is maladaptive for the current environment. While they can be managed, it and some of the other sources, also says that they gain more weight on the same number of calories, which is the crux of the debate here.

Except for scientific curiosity, so what? Individual weight is a personal " struggle " and I don't use that word casually. We should resist the very human tendency to judge the behaviors, intentions, motivations, whatever of others. I have been obese before and could easily return to that condition without effort. After losing weight and keeping it off for a few years (for the first time in my life), I recall going through a period of anger at overweight people who complain about how difficult it is.... No sh__ Sherlock! I hope I have mellowed as I have habituated to my more healthy current eating pattern and it gets a little easier. People who never knew the fat me don't believe me when I tell them. This is also a little upsetting. We should get a merit badge or a star or something, but better health should be and is adequate reward and motivation for the effort. Many people (like me) have gravitated to CR for the immediate health benefits rather than the unproven promise of extending life. Improved health will in fact extend productive high quality life experience. The bottom line is that we are all the subject of a one rat experiments. If we don't lose weight eating calorie level X, reduce to X-n. If we can't cover adequate nutrition at X-n I'd be tempted to temporarily cut calories further as the science of adequate nutrition is not any better than the science of energy balance. Nutrition for many nutrients (like fat based vitamins) is stored and averaged over time not fully consumed daily. I find most of this debate off the point. Losing weight really is as simple as eating less... " Simple " is not the same thing as easy. This is never easy. So please excuse those of us who have already mastered our weight, at least for now, because it can be a heady experience, especially if we were formerly overweight and/or obese. We often feel this gives us special license to to speak out with hard earned authority. I hope you will also get to enjoy the health benefits of lower weight and the self satisfaction of mastering your personal situation. While it may not always be apparent I don't think I'm speaking out of school when I suggest that everyone here wishes you and anyone else in a similar situation complete success. JR PS: I vaguely recall seeing a report (on one of those sensational TV programs) about dietary and lifestyle changes being the root cause of the Pima's present unusually high incidence of obesity and diabetes. I don't recall the details but living off subsistence farming is obviously different than sitting around eating govt supplied cheese and processed corn meal.

Guest guest Posted August 7, 2006 Report Share Posted August 7, 2006 Hmmm... you are arguing both sides of things here. Which is it? 1) the caloric value of food is absolute, and what yields 100 kcal for one person will yield 100 kcal for all people, and all people, with the same activity, will gain one pound per 3500 kcals ingested OR 2) the exact same food can yield different calorie amounts for different people, according to their bodies ability to harvest the energy from the chemical bonds in the food, and food that yields 3500 kcals for one person, may yield more kcals for a second person, resulting in greater weight gain for the second person At least you are now agreeing that resting metabolic rates can differ, therefore, two people eating exactly the same number of calories could gain different amounts of weight, if there were no other variables. My point exactly. Just because a person is eating x calories and gains more weight than a second person, does not mean that they are lying about how many calories they are eating. It is that simple. The measuring and verifiability is only good within the accuracy of the expenditure estimation system, and with doubly labled water, is known to vary up to 21% . Of course we do not defy the laws or thermodynamics, or they would not be the laws of thermodynamics. But the laws of thermodynamics have nothing to do with differing abilities of differing bodies to harvest energy from the same substances by virtue of their differing enzymes. Where we clip a side group, what side groups we clip and how we fold a molecule to do that, can make a big difference. And I agree that most of us are maladapted for our current food environment. Which is also one of my points, so I appreciate your ceding that as well.

Guest guest Posted August 7, 2006 Report Share Posted August 7, 2006 The obesity epidemic has exploded in the last 30 years and mostly amongst people who were alive 30 years ago... So what changed? At the end of the day.. inspite of all other variables, an overweight or obese person must consume more calories than they burn to gain weight. I see man obese people every day who werent obese 10-30 years ago. What happened? Did the other variables (their genetics, or their RMR, or their hormones, etc) change? No. But, the food industy has figured out how to concentrate the calories in food, make them more appealing and easier to get. Never before could you get a small package of " food " that could deliver you 3000 calories and be so processed and refined you almost dont even have to chew it to get it done. MOst of this change has happened in the last 30 years. While at the same time.. we can get thru our days in society while spending much less energy without even realizing it. We now have people using electric scooters and carts because they are lazy (see recent article in WSJ). And that new human transport thing from Sharper Image or tone. PE is out of most schools. Its not safe for kids to walk to school. 66% of golfers surveyed are obese.. yet it wasnt that way 30 years ago, when most of them carried their clubs and walked the course. All this has changed in 30 years. >>> Hmmm... you are arguing both sides of things here. Which is it? That was my question for you. No one is doubting these variables, but you still have to create the energy excess to gain weight. Do variables exist in RMR, enzymes, the measure of calories in and calories out? Of course. Who is denying or aruging that?? But that is not what has changed so rapidly in such short a time. Even so, if all and any of the variables could be measured, to the exact minute detail, where would that leave us? If you eat a banana and I eat the same banana and you get 100 calories and I get 90, or if we both get 100, isnt the issue. That variable in what ever degree, has always existed since time memorial. At the end of the week, when i get on the scale, if it going up, then I am taking in more than I burn and if it is going down, i am burning more than I take in. That is pretty simple. >>> At least you are now agreeing that resting metabolic > rates can differ, > therefore, two people eating exactly the same number > of calories could gain > different amounts of weight, if there were no other > variables. Umm... Again... I dont think I Or anyone else here has ever argued differently. You may not have liked Rodneys response but I dont see where all this comes from. Everyones metabolic rate is unique to them and their studies I have posted here that have been done over the years have shown take a dozen women of the same age, ht and wt, and they have different metabolic rates. THat is no startling new paradigm. Yes, we dont have the best ways to measure it, but there are ways. This is why you can only use those standard formulas as a guide, not a law. > Just because a person is eating x calories and gains > more weight than a > second person, does not mean that they are lying > about how many calories > they are eating. NO, and with all due respect, I am sure many dont intend to lie. There is the second problem., again no secret to this list or anyone on it, that the measuring stick we use for calories in and calories out is not very good. So, they may be trying their best, but their may be errors and variables in other areas. The variables posted in the study i originally posted isnt saying they were lying, just that there was a variance. Do some lie?? of course they do. Its human nature to under estimate the bad and overestimate the food. When they tested a dozen muffins at stores and found most contained on average 25% more calories than their label stated, whose fault is that. >>> It is that simple. Right. We actually have a very simple system to tell how anyones attempt at measuring the balance in and out is going... its called the scale.. and if you use the same scale at the same time of the day, on a regular basis, regardless of all the variables, you will see how good your balance is going. > But the laws of > thermodynamics have nothing to > do with differing abilities of differing bodies to > harvest energy from the > same substances by virtue of their differing > enzymes. No doubt. But, in particpating in the world around me, and studying 1000s of people every year, i just dont see this as the issue. > And I agree that most of us are maladapted for our > current food environment. Environment, not just food. THere is also the other side of the equation. BUt even so, its not an excuse or rational for people to keep on the path that is killing them and causing a major health and economic crisis in this country. I wrote this recently in response to a similar discussion on another list... (some points may be repeated but the story of the patient is relevant.) ............The problem isnt that calories in vs calories out doesnt work, the problem is that there are many assumptions made about calories in and calories out that are inaccurate or have lots of variance. Many of the ways of measuring these variables are inaccurate. How accurate are food labels (which round off and have an allowed error rate), exercise machines (which have incredible variance between them), metabolic equations for determining RMR (some have error rates upward of 30% in the obese), and of course, we have patient recall and honesty to deal with in tracking food intake. There is lots of room for error in everyone of these variables. What I have seen often is that patients arent very honest when they first come for counseling/help. They dont admit to everything they eat as they may be embarrassed or feel guilty. They give you a figure of like 1000-1200 calories a day (usually all salads and healthy food) and say they cant lose weight, and exercise often. But, they havent admitted to all the junk food they eat. Then, when asked to keep a journal they now admit to more or all of what they eat as they are trying to do better, and it looks better. So, while it may seems as though they are eating more, they are only being honest about more and actually eating less total calories. It may also seem like more food to them, and they may report that they feel fuller, cause healthy food is generally lower in calorie density, have a greater volume per calorie, and more satisfying than junk foods. I Recently did an experiment with one such client. After working with them to find out how many calories they " said " they ate without being able to loose weight, we than extablished for them to follow that calorie level while at the center under a more controlled environment. Lo and behold, at the exact same calorie level, (and exercise level) they started losing weight and kept losing it over the next few weeks. Now, what was most interesting was that after a few weeks, they joined me on a dining out excursion, that I take my patients on every week. There was about 12 of us that night and she was sitting down the table at the other end. I overheard part of her conversation and her food discussions with some of the other patients at the table and it included the intake of lots of junk food, ice cream and cake and the dinner parties she hosted, that she never admitted to in the original discussions with me about her " usual daily intake " .

Guest guest Posted August 8, 2006 Report Share Posted August 8, 2006 Hi JW: Thanks for that link again. I took another look at it over the weekend. I think you are going to have to explain to me what you believe the significance of that paper to be, because it seems I do not get the same message from it you do. This is what I understand it to say: 1. Adiponectin (ADPN) is " abundantly expressed in adipose tissue " . I might have thought that would mean that people with lots of adipose tissue would have plenty of ADPN, but apparently the opposite is true. 2. ADPN sensitizes the body to insulin (so more of it is 'good'). " Adiponectin is an adipokine that is specifically and abundantly expressed in adipose tissue and directly sensitizes the body to insulin " . So too little of it causes insulin resistance, which is bad news. At the end of the second paragraph it says: " .... insulin resistance caused by obesity, a state of increased adiposity " . It does not say: " obesity caused by insulin resistance " the latter of which, as already noted, is caused by insufficient ADPN. 3. Inadequate ADPN is caused by the interaction of genetic factors and obesity. First paragraph: " hypoadiponectinemia, caused by interactions of genetic factors such as SNPs in the Adiponectin gene and environmental factors causing obesity " . Note: not the other way around ...... not that adiponectin causes obesity. 4. Obesity, they say, is caused by " environmental factors " . See the quote immediately above. Initially I took that to mean things like air pollution. But reading further down it becomes apparent that their use of the term " environmental factors " means in an environment of an abundant and attractive food supply. In the third paragraph it says: " While white adipose tissue (WAT) provides a survival advantage in times of starvation, excess WAT is now linked to obesity-related health problems IN THE CURRENTLY NUTRITIONALLY RICH ENVIRONMENT " (my caps, for emphasis). So the " environment " factor that is seen by this paper as a cause of obesity refers to a 'nutritionally abundant' food supply. So, as I read it, the original causation is an abundant food supply; this results in obesity; obesity causes too little ADPN; insufficient ADPN causes insulin resistance (and metabolic syndrome, etc.). This is not especially surprising as many here, I think, have supposed that this was the route of causation. If you have a different view of this, JW, please say so.

Guest guest Posted August 8, 2006 Report Share Posted August 8, 2006 The bottom line is the fat grows, the body adds muscle to keep the guy moving, and heart moves the fluids until it fails. But something causes the adipose to grow uncontrolled. Of course food is needed for the body to grow. But it's the imbalance of controlling hormones which allow it to happen. Something stimulates obesity even in youth, a problem I never had neither do my children or gchilren, yet they exist in the same environment of high food supply. WHY are they not eating to satisfy a high hunger? What it says is that adiponectin is the controlling hormone and is reduced in obese people. IGF-1 is the growth hormone. For every system in the body you have a driver hormone and a controller hormone. A feedback control system much like a thermostat. In order for you to accumulate fat there must be a drop in ADPN. From table 1 we saw ADPN listed as the only downregulator. ADIPOSE MAKES ADPN. At the same time the insulin receptor restricts insulin, yet allows IGF-1 in to grow. Insulin is required to convert fat (fat lypolysis) to get it out of the adipose into the blood stream. If you change that conversion just slightly more fat is stored than is released, so the adipose grows. And that's what happens in obesers. It's not clear the cause of the adipose IR, whether it makes less adiponectin as a result of IR, or vice versa. Clearly the idea should be to attack that hormone problem. They won't prescribe adiponectin, because it is thought to cause wasting. This is another complex system, and the adipose is not controlled by the central nervous system. What happens in obesers, they will tell you, they are hungry even eating large amounts of food. The adipose is sucking up the nutrients and growing. Clearly there is a problem here that is just not being addressed by nutritionists who think you can always starve yourself and lose weight - you can but it won't be all adipose, and you have no idea where the lost weight comes from. Fortunately, my fat was mostly visceral when I lost 60 #, but I noticed all the fat didn't go away. Exercise has no effect on this "fat that won't come off". Funny thing I read about bears, is some don't make it thru the winter - not enough stored nutrients. BUT they will still be fat left in the corpse. Bears can recover their organ tissue in refeeding, humans cannot. That's not a small issue with me. And we will never get out of the clinics if the 300#ers lived longer after losing 100# than they would have untreated. They won't run a test like that and no one can say they were benefited. I started asking the question does the body conserve heart and organ tissue and just give up muscle tissue in dieting. No definitive answer yet. Until that is answered in humans, I vote against recommending weight loss to anyone. IMO, the nutritionists need to wake up, and the docs need to learn how to treat obesity. The endocrinologists at Aventis know something we don't know. It's a medical problem. Regards. [ ] Re: You Cant Fix What You Deny Hi JW:Thanks for that link again. I took another look at it over the weekend. I think you are going to have to explain to me what you believe the significance of that paper to be, because it seems I do not get the same message from it you do.This is what I understand it to say:1. Adiponectin (ADPN) is "abundantly expressed in adipose tissue". I might have thought that would mean that people with lots of adipose tissue would have plenty of ADPN, but apparently the opposite is true.2. ADPN sensitizes the body to insulin (so more of it is 'good'). "Adiponectin is an adipokine that is specifically and abundantly expressed in adipose tissue and directly sensitizes the body to insulin". So too little of it causes insulin resistance, which is bad news. At the end of the second paragraph it says: ".... insulin resistance caused by obesity, a state of increased adiposity". It does not say: "obesity caused by insulin resistance" the latter of which, as already noted, is caused by insufficient ADPN. It's a loop, chicken and egg thing. So increase ADPN somehow and the loop should respond to a different point. And this is why growth hormone is not being bandied about anymore. Hormones are catalysts and a very small amount can shift the system - maybe out of control. Unfortunately there are vicious cycles. Anorexia is one. 3. Inadequate ADPN is caused by the interaction of genetic factors and obesity. First paragraph: "HYPOadiponectinemia, caused by interactions of genetic factors such as SNPs in the Adiponectin gene and environmental factors causing obesity". Note: not the other way around ...... not that adiponectin causes obesity. Right, HYPER ADPN would cause wasting.4. Obesity, they say, is caused by "environmental factors". See the quote immediately above. Initially I took that to mean things like air pollution. But reading further down it becomes apparent that their use of the term "environmental factors" means in an environment of an abundant and attractive food supply. In the third paragraph it says: "While white adipose tissue (WAT) provides a survival advantage in times of starvation, excess WAT is now linked to obesity-related health problems IN THE CURRENTLY NUTRITIONALLY RICH ENVIRONMENT" (my caps, for emphasis). So the "environment" factor that is seen by this paper as a cause of obesity refers to a 'nutritionally abundant' food supply. It is also thought the IGF-1 in milk causes it. Could be the obeser is more sensitive than others to growth hormone. So, as I read it, the original causation is an abundant food supply; this results in obesity; obesity causes too little ADPN; insufficient ADPN causes insulin resistance (and metabolic syndrome, etc.). This is not especially surprising as many here, I think, have supposed that this was the route of causation. Yes, but by that logic I could blame the abundant food supply for everything. EG, for causing us to live so long we get more cancer. If you have a different view of this, JW, please say so.Rodney.>> Please read this again and try to understand the obese are suffering a problem in hormone balance.
