And for some it has been a life ending event. The issue isnt if you lose weight. You can lose weight and change your life taking amphetamines, cocaine, tobacoo, or stomach sugery. CR-ON is not about just losing weight. Its about ON also. I didn't set the nutritional guidelines/needs of humans. But, I found it impossible to analyse an atkins style diet and have it meet the nutrition requirements of the body as defined by the leading health organizations of the world. >>think the best strategy is not to push any idea to the extremes and to sort of keep a middle of the road approach as much as possible. We just don't have the data right now to know which is the best approach. Then my question is why would you be here doing CR-ON which is based on restricting calories while providing optimum nutrition and considered by many to be extreme in and of itself. I understand you are trying to intellectulize your own approach to it, and god bless you for doing it, but how can you say you are for a " middle of the road " approach when what you are doing is based on maybe one short term study and an approach that many would consider anything but middle of the road in what is also considered an anything but middle of the road endeavor. You are talking extreme (QOD) of the extreme (CR-ON) We have plenty of good data and that is what this list is about. Good data. And we discuss it all the time here, And Walford was pretty clear in his recommendations, which are the data that started all this and, which were no where near what Atkins recommends. If you have better data, and I mean much better data, and not just one or two studies, than lets see it. There are quite a few short term studies on Atkins which showed the subjects on Atkins diet didn't do well. The one year study on Atkins showed that those on the Atkins diet didn't do well. The 2 year study on kids on an atkins type diet (ketogenic) showed terrible results. There are other studies documenting problems and deaths with the diet. I have read them all, spoken with the authors and written reviews of them all. These have all been posted here. My challenge to you is simple. Do the nutritionaly analysis of what you are considering, recommendation, or doing. Not just sodium and potassium or calories, but all the known nutrients. See if what you are doing/recommending/considering or arguing for, even comes close to meeting the needs of humans as best we know them. We can argue how correct the estimates of the needs are at another point, but right now they are the best we have, so lets go with them for now. The goal is simple Creat the most nutritionaly dense diet you can on the least amount of calories needed to maintain a healthy CR weight/BMI and show me what you come up with. Beyond that, I think this discussion is redundant and pointless. Jeff Quote Link to comment Share on other sites More sharing options...

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 >>>The randomized double-blind trials of Atkins type of diets so far, if anything, according to my reading, have supported the claim that Atkins is a very effective, short term way to lose weight, and blood markers of cardiovascular risk have, if anything, been improved vs. low fat, high carb diets. Weight loss alone will lower CRP, and so someone who winds up losing 100 lbs on Atkins who has failed numerous other approaches may well be better off than before. From an article I helped write. .... It's criminal how few health writers take the time to read - really read - and dissect newly published scientific articles. Too often, snappy headlines overrule substance. Recently, that's what happened with two new studies comparing low-carb, Atkins-style diets with conventional low-fat diets. Both were published in the May 18 issue of the ls of Internal Medicine. Both groups of authors warned that the studies had serious flaws. The first, which followed 132 obese adults at Philadelphia Veterans Affairs Medical Center, had a very high dropout rate (34% of the dieters) as well as " suboptimal dietary adherence of the enrolled persons. " In the second study, funded by the C. Atkins Foundation and conducted at Duke University, the 120 moderately obese dieters were followed for only 24 weeks, and the Atkins followers received nutritional supplements that the low-fat dieters did not receive, which, the authors feared, might have skewed results because the supplements have favorable effects on cholesterol and triglyceride levels and weight loss. But what we, the American public, saw in the media were headlines like " Low- Carb Is King! " and " Low-Carb Dieters Knew It All Along. " Unbelievable. Literally. Here are the real facts, gleaned from an in-depth, sentence by sentence, graph by graph, analysis of the two articles AFTER ONE YEAR, WEIGHT LOSS WAS SIMILAR BETWEEN THE ATKINS DIETERS AND THE LOW-FAT DIETERS. True, at the six-month mark in both studies, the Atkins dieters had lost more weight, but the longer of the two studies, the one that lasted a full year, found that the low-fat dieters had caught up and shed about the same amount of weight, 11 pounds, at year's end. The Atkins diet, surmised lead author Dr. Yancy of Duke University, might be harder to maintain after six months compared with the low-fat approach. In fact, notes Dr. Kenney, " most of the people on the Atkins meat- and fat-rich regimen were regaining lost weight by the end of the year while the low-fat dieters continued to lose weight for the entire first year. " LDL " BAD " CHOLESTEROL ROSE IN 30% OF ATKINS DIETERS. The Duke University study measured LDL cholesterol levels and found that after one year overall changes in LDL levels did not differ between the Atkins and low-fat dieters, but 30% of the Atkins diets did experience increases of LDL levels of 10% or more. In fact, two of the 60 Atkins dieters who began the study dropped out because of high LDL cholesterol levels: one suffered an LDL increase of 182 to 219 in four weeks; the second dieter's LDL shot up from 184 to 283 in three months. A third Atkins participant developed chest (angina) pain and was subsequently diagnosed with coronary heart disease. TWO OF THE ATKINS DIETERS DIED. Though the Philadelphia study was small in number - just 66 men and women were on the Atkins diet - and their average age was only 53 years old, two of the Atkins dieters died, one from hyperosmola coma five months into the study, and the second from severe ischemic cardiomyopathy ten months into the study. No one had died on the low-fat diet. THE ATKINS DIETERS SUFFERED FAR MORE SIDE EFFECTS. In the Duke University study, twothirds of the Atkins dieters reported constipation problems, 60% reported headaches, and 25% complained of a general feeling of weakness. The Atkins followers were five times more likely to suffer from muscle cramps compared to the low-fat dieters, and three times more likely to have diarrhea. THE LOW-FAT DIET WAS NOT AN OPTIMAL LOW-FAT DIET, NOT EVEN CLOSE. " It's no surprise that the weight loss, cholesterol, and triglyceride results of the low-fat diets in these studies were disappointing. The diets themselves were the worst kind of low-fat diets, " The Philadelphia study reported data on what the subjects actually ate, and the numbers are illuminating. At the end of one year, notes Dr. Kenney, " there was no significant difference in the amount of saturated fat on the Atkins diet and the low-fat diets. " (What?! And the latter was supposed to be low-fat and heart-healthy?!) Moreover, the total amount of fat on the low-fat diet (about 30% of calories) was at least twice as high as the amount of fat on the Pritikin Eating Plan and four to five times higher in saturated and trans fats. It appears, too, that the low-fat dieters in the Philadelphia were not filling their plates with fruits and vegetables. The fiber content of their diet remained constant throughout the year, " proving that their increased carbohydrate consumption came from refined carbs, like sugar and refined grains, " . Lots of " bad " fat? Lots of " bad " carbs? This is not a healthy low-fat diet, certainly not one that would impact favorably on weight loss, blood lipids like cholesterol, and other cardiovascular risk factors, all of which have been shown to dramatically improve on the Pritikin Program. AS LONG AS YOU ARE LOSING WEIGHT, YOUR BLOOD LIPIDS IMPROVE. Atkins enthusiasts trumpeted these new studies as proving that the Atkins diet brings down triglycerides and improves cholesterol levels, " but weight loss, regardless of the type of diet you're on, improves blood lipids, " Moreover, the dieters in the Atkins group took fish oil supplements, proven to lower triglyceride levels; the other dieters took no supplements. Hardly a fair comparison. " The real question is: What do your arteries look like? What happens after years of following a diet high in saturated fat? True, the Atkins dieters in the two new studies saw their HDL " good " levels go up, " but HDL levels are a complex issue, " . " HDL has subfractions. Some of these subfractions are made up of the protective 'good' part of HDL, the part that returns excess cholesterol to your liver, where it's recognized as waste material and disposed of. But some HDL subfractions are made up of unprotective HDL. Which type did the Atkins diet raise? We don't know. But given the fact that two of the Atkins dieters died and one developed angina, I'm skeptical that the rise in HDL came from the beneficial subfractions. " Overwhelming research has proven which diet is best, one that's high in fiber, low in fat, and with plenty of fruits and vegetables, concluded Dr. Katz of Yale University's Preventive Medicine Research Center in an interview with ABC News on May 17: " We have ample evidence that this basic dietary pattern prevents heart disease, cancer, diabetes, premature death, and obesity.

Jeff Diet Wars Information Myth # 1: Low-Fat Diets Have Failed It has been repeatedly argued that low-fat diets have failed because, as the theory goes, " the amount of fat in the US has declined while at the same time the percent of the population that is overweight/obese has dramatically increased. " Facts: The amount of fat in the American diet has not declined. It only appears to have dropped because it has dropped as a percent of total calories. However, the total amount of calories consumed by Americans has risen at an even greater rate than the total amount of fat consumed, so while the " percentage " of fat consumed has dropped slightly based on comparing it to the total calories consumed, the actual amount of fat and calories consumed has gone up.

Facts: The few recent studies on high protein diets, have all been short term (less than 6 - 12 months), had a very high drop out rate ( in some groups over 50% didn't finish the study) and poor adherence to the diets. Most of the beneficial effects associated with those on the high protein diet was due to the initial weight loss. In reality, diets that are very low in carbohydrates and high in saturated fat and cholesterol have been shown to have very adverse effects on blood lipids when weight is maintained. Diets high in saturated fat and cholesterol have consistently been associated with an increased risk of clogged arteries and heart attacks. A one year study that compared a very low fat high fiber diet (as advocated by Pritikin) to a low carbohydrate Atkins style diet showed better weight loss and remarkably better improvements in all blood lipids and other risk factors for cardiovascular diseases. (Preventative Cardiology 5(3): 110-118, 2002) Recently a study on children following an " Atkins Style " very low carbohydrate, high fat diet for 6 months to 2 years found that all blood lipids were negatively impacted with Triglycerides and LDL increasing 50 -60% Supporting Attachment: 1.

Myth # 3: As Promoted In Many Best Selling Diet Books, The Key To Long Term Successful Weight Loss Is Restricting Carbohydrate And Increasing The Intake Of Fat And Protein. Facts: If anything, the opposite is more likely true. Success leaves clues. The people who have been successful in the United States at losing weight and keeping it off long term are part of a study called the National Weight Control Registry (NWCR). To qualify for the NWCR, someone must have lost at least 30lbs and kept it off for at least a year and have it documented with before and after pictures and medical records. The average weight loss is 65lbs and has been kept off for 6 years. There are 4500 people who now meet the criteria in the registry. Less than 1% of the subjects in the NWCR have used a high protein, low carbohydrate diet to lose weight and keep it off. In fact, most have used a low-fat, high carbohydrate, high-fiber diets with exercise. A USDA study on 10,000+ Americans found that the leanest Americans were those following a low-fat, high-carbohydrate diet full of fruits, vegetables, grain products, low-fat dairy foods, and small amounts of low-fat meat, poultry and fish. By contrast, Americans in the very low-carbohydrate (high protein) group were the heaviest. (Journal of the American College of Nutrition 2002;21:268-274.) The scientific review: " Popular Diets: Correlation To Health, Nutrition and Obesity. " It reviews data on 10,014 American adults and concludes that people on low-carbohydrate diets had the highest BMI's. The March 2003 recommendations from the World Health Organization concluded that the optimal diet for losing weight and preventing disease is one that is low in fat and high in natural, fiber-rich carbohydrates like fruits, vegetables, and whole grains. A study that critically reviewed the health advantages and disadvantages of popular weight loss diets found the diets low in fat and high in carbohydrates and fiber provide the greatest health benefits and also lowered the risk for cardiovascular disease and diabetes. The review also noted that while high fat diets may promote short-term weight loss, they increase the risk for cardiovascular disease and the progression of atherosclerosis. SUPPORTING ATTACHMENTS 1.

These High Carbohydrate Foods, Also Cause An Increase In Blood Sugar And Will Lead To Diabetes. Facts: Claims that high-GI foods or high-glycemic load foods increase hunger and promote overeating and obesity conflict with a lot of research. First, a study that compared the satiety/calorie (called satiety index) from a wide variety of foods found that the white potato had the highest satiety index. It was considerably higher than fish, eggs, beef or cheese and other high-protein foods. In other words, despite its high glycemic index, it was the food least likely to lead to overeating. The University of California Berkeley Wellness Letter reviewed the glycemic index and the many claims made about it. The author said, " the glycemic index is of little practical use for designing an eating plan. Moreover, it's not even clear that avoiding foods high on the index is even beneficial. " They concluded that " if you are trying to lose weight, calories do count, far more than the glycemic index. " A recent published review of the glycemic index (F Xavier Pi-Sunyer), explains why it is not recommended to base food choices solely on the glycemix index. The author also concludes that a more important public message would be to recommend a decrease in total caloric intake and an increase in physical activity. Another study looked specifically at the claims made in the best selling diet book " The Zone " which is based on the glycemic index and the control of insulin levels for weight loss. The author of the study found that not only were the claims made in the book The Zone not supported by the scientific literature, it found that the scientific literature was in actual " opposition " to the claims.

There is a big difference between unrefined/unprocessed carbohydrate foods that are rich in fiber and water and low in calories (like peas and corn) that are healthy and refined processed carbohydrate foods that are low in fiber and water content and high in calories (like pretzels and crackers). Unfortunately, both types of carbohydrates are usually lumped together, and vilified equally in the popular diet books and media. The main reason that high carbohydrate diets have a presumably bad impact on blood lipids and atherosclerosis is that in the majority of the studies high carbohydrate diet was a diet high in refined and processed carbohydrates. However, there are many studies that show when a diet is based on the unprocessed, unrefined carbohydrates that are high in fiber and low in calories, they reduce the risk for diabetes and cardiovascular disease. Even the latest recommendations for diabetes that was just published in the January 2004 issue of Diabetes Care, says that a low fat, high carbohydrate, high fiber diet is beneficial for use in the prevention and treatment of diabetes. In addition, they state that it is also more likely to lead to weight loss than diets higher in fat. The distinction between unrefined unprocessed carbohydrates and refined processed carbohydrates must be made when discussing the role and/or success of a high carbohydrate diet in relation to weight loss and health. Anyone who understands this difference would not advocate a low-fat diet that is high in the refined processed carbohydrates and low in fruits and vegetables for weight control. And, it is a distinction that must be made clear to both the media and the general population. In fact studies published by Pritikin and others have shown that a diet consisting largely of whole grains, fruits and vegetables with a little fatty fish and non-fat dairy products dramatically reduces practically all known and suspected risk factors for coronary heart disease. Indeed, the only diet shown to reverse coronary artery disease in most human subjects is a very-low-fat, high carbohydrate, high-fiber diet. Supporting Attachment: 1. American Diabetes Association.

Fact: A carefully controlled study was done where people were allowed to eat as much as they wanted from diets that contained similar foods that varied only in the fat content. The result was that when similar foods contained more fat, people consistently needed to eat far more of the food (and so far more calories) in order for them to feel as satisfied as when they ate the low fat versions of the same foods. There is much discussion in the media and the popular press today about which nutrient (protein, fat or carbohydrate) is the most filling or what is the optimal ratio between the nutrients in order to promote the most weight loss. In truth, as studies have shown, the nutrient or the ratio of the nutrients is far less important than what everyone has thought. What has turned out to be the most important issue in filling up on the least calories is the issue of " calorie density " . Calorie density is simply a measure of the concentration of calories in food. Fat has the highest calorie density of the three nutrients, much higher than either carbohydrate or protein. Therefore, the addition of any fat to food (including the so called " good fats " ) increases the calorie density of any food that it is added to and so leads to the over consumption of calories. What we are now learning from this information is that there is a far better way to lose weight and that is to reduce the overall calorie density of the diet and of the foods in the diet. In addition, choosing foods that are lower in calorie density, help prevent the overeating of foods that are higher in calorie density. 1. Lissner L, et al.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 >>>The randomized double-blind trials of Atkins type of diets so far, if anything, according to my reading, have supported the claim that Atkins is a very effective, short term way to lose weight, and blood markers of cardiovascular risk have, if anything, been improved vs. low fat, high carb diets. Weight loss alone will lower CRP, and so someone who winds up losing 100 lbs on Atkins who has failed numerous other approaches may well be better off than before.

Jeff Diet Wars Information Myth # 1: Low-Fat Diets Have Failed It has been repeatedly argued that low-fat diets have failed because, as the theory goes, " the amount of fat in the US has declined while at the same time the percent of the population that is overweight/obese has dramatically increased. " Facts: The amount of fat in the American diet has not declined. It only appears to have dropped because it has dropped as a percent of total calories. However, the total amount of calories consumed by Americans has risen at an even greater rate than the total amount of fat consumed, so while the " percentage " of fat consumed has dropped slightly based on comparing it to the total calories consumed, the actual amount of fat and calories consumed has gone up.

Facts: The few recent studies on high protein diets, have all been short term (less than 6 - 12 months), had a very high drop out rate ( in some groups over 50% didn't finish the study) and poor adherence to the diets. Most of the beneficial effects associated with those on the high protein diet was due to the initial weight loss. In reality, diets that are very low in carbohydrates and high in saturated fat and cholesterol have been shown to have very adverse effects on blood lipids when weight is maintained. Diets high in saturated fat and cholesterol have consistently been associated with an increased risk of clogged arteries and heart attacks. A one year study that compared a very low fat high fiber diet (as advocated by Pritikin) to a low carbohydrate Atkins style diet showed better weight loss and remarkably better improvements in all blood lipids and other risk factors for cardiovascular diseases. (Preventative Cardiology 5(3): 110-118, 2002) Recently a study on children following an " Atkins Style " very low carbohydrate, high fat diet for 6 months to 2 years found that all blood lipids were negatively impacted with Triglycerides and LDL increasing 50 -60% Supporting Attachment: 1.

Myth # 3: As Promoted In Many Best Selling Diet Books, The Key To Long Term Successful Weight Loss Is Restricting Carbohydrate And Increasing The Intake Of Fat And Protein. Facts: If anything, the opposite is more likely true. Success leaves clues. The people who have been successful in the United States at losing weight and keeping it off long term are part of a study called the National Weight Control Registry (NWCR). To qualify for the NWCR, someone must have lost at least 30lbs and kept it off for at least a year and have it documented with before and after pictures and medical records. The average weight loss is 65lbs and has been kept off for 6 years. There are 4500 people who now meet the criteria in the registry. Less than 1% of the subjects in the NWCR have used a high protein, low carbohydrate diet to lose weight and keep it off. In fact, most have used a low-fat, high carbohydrate, high-fiber diets with exercise. A USDA study on 10,000+ Americans found that the leanest Americans were those following a low-fat, high-carbohydrate diet full of fruits, vegetables, grain products, low-fat dairy foods, and small amounts of low-fat meat, poultry and fish. By contrast, Americans in the very low-carbohydrate (high protein) group were the heaviest. (Journal of the American College of Nutrition 2002;21:268-274.) The scientific review: " Popular Diets: Correlation To Health, Nutrition and Obesity. " It reviews data on 10,014 American adults and concludes that people on low-carbohydrate diets had the highest BMI's. The March 2003 recommendations from the World Health Organization concluded that the optimal diet for losing weight and preventing disease is one that is low in fat and high in natural, fiber-rich carbohydrates like fruits, vegetables, and whole grains. A study that critically reviewed the health advantages and disadvantages of popular weight loss diets found the diets low in fat and high in carbohydrates and fiber provide the greatest health benefits and also lowered the risk for cardiovascular disease and diabetes. The review also noted that while high fat diets may promote short-term weight loss, they increase the risk for cardiovascular disease and the progression of atherosclerosis. SUPPORTING ATTACHMENTS 1.

These High Carbohydrate Foods, Also Cause An Increase In Blood Sugar And Will Lead To Diabetes. Facts: Claims that high-GI foods or high-glycemic load foods increase hunger and promote overeating and obesity conflict with a lot of research. First, a study that compared the satiety/calorie (called satiety index) from a wide variety of foods found that the white potato had the highest satiety index. It was considerably higher than fish, eggs, beef or cheese and other high-protein foods. In other words, despite its high glycemic index, it was the food least likely to lead to overeating. The University of California Berkeley Wellness Letter reviewed the glycemic index and the many claims made about it. The author said, " the glycemic index is of little practical use for designing an eating plan. Moreover, it's not even clear that avoiding foods high on the index is even beneficial. " They concluded that " if you are trying to lose weight, calories do count, far more than the glycemic index. " A recent published review of the glycemic index (F Xavier Pi-Sunyer), explains why it is not recommended to base food choices solely on the glycemix index. The author also concludes that a more important public message would be to recommend a decrease in total caloric intake and an increase in physical activity. Another study looked specifically at the claims made in the best selling diet book " The Zone " which is based on the glycemic index and the control of insulin levels for weight loss. The author of the study found that not only were the claims made in the book The Zone not supported by the scientific literature, it found that the scientific literature was in actual " opposition " to the claims.

There is a big difference between unrefined/unprocessed carbohydrate foods that are rich in fiber and water and low in calories (like peas and corn) that are healthy and refined processed carbohydrate foods that are low in fiber and water content and high in calories (like pretzels and crackers). Unfortunately, both types of carbohydrates are usually lumped together, and vilified equally in the popular diet books and media. The main reason that high carbohydrate diets have a presumably bad impact on blood lipids and atherosclerosis is that in the majority of the studies high carbohydrate diet was a diet high in refined and processed carbohydrates. However, there are many studies that show when a diet is based on the unprocessed, unrefined carbohydrates that are high in fiber and low in calories, they reduce the risk for diabetes and cardiovascular disease. Even the latest recommendations for diabetes that was just published in the January 2004 issue of Diabetes Care, says that a low fat, high carbohydrate, high fiber diet is beneficial for use in the prevention and treatment of diabetes. In addition, they state that it is also more likely to lead to weight loss than diets higher in fat. The distinction between unrefined unprocessed carbohydrates and refined processed carbohydrates must be made when discussing the role and/or success of a high carbohydrate diet in relation to weight loss and health. Anyone who understands this difference would not advocate a low-fat diet that is high in the refined processed carbohydrates and low in fruits and vegetables for weight control. And, it is a distinction that must be made clear to both the media and the general population. In fact studies published by Pritikin and others have shown that a diet consisting largely of whole grains, fruits and vegetables with a little fatty fish and non-fat dairy products dramatically reduces practically all known and suspected risk factors for coronary heart disease. Indeed, the only diet shown to reverse coronary artery disease in most human subjects is a very-low-fat, high carbohydrate, high-fiber diet. Supporting Attachment: 1. American Diabetes Association.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 Hi folks: My view of Atkins is that a study needs to be done to assess the COMPONENTS of weight lost on both a Pritikin diet and an Atkins diet. We all know of people who have gone on an Atkins diet, have been eating huge numbers of calories and have quickly lost appreciable weight. Most of us here, hopefully, know that this does not make a lot of sense. We know that a pound of body weight is associated with about 3500 calories. So it is clear that on an Atkins diet the quick initial weight loss is not real, caloric, weight but something else. The logic of the situation suggests the following: Dr. Atkins unfortunate experience in hospital confirms (even according to the accounts of the Atkins Nutritionals people) that when someone who has been on the Atkins diet reverts to a diet that includes normal amounts of electrolytes and carbohydrates, sixty pounds of weight can be added in very short order - in Dr. Atkins case less in than two weeks I believe? Clearly, this is not real caloric weight. It is water. Similarly, this very strongly suggests that the weight loss experienced in the early stages of an Atkins diet is not real caloric weight either - how could it be with the huge caloric intake? The weight loss that appears on the scales is largely, perhaps entirely, accounted for by the dehydration effect of the diet. So my hypothesis is that if such a study were conducted, and the components of weight lost on a (GENUINE) Pritikin diet and an Atkins diet were compared, then the following is approximately what would be found (I hope the formatting works out in the following table - this is not a great medium for communicating tabular information): COMPONENTS OF WEIGHT LOST ON TWO DIET TYPES ------------------------------------------- Months >>> -----0-----3-----6-----9-----12 -------------- --- · --- · --- · --- · --- Atkins: Total wt ------250---210---190---190---190 H20 lost -------0-----40----60----60----60 non-H20 --------0------0-----0-----0-----0 Pritikin: Total wt ------250---235---220---205---190 H2O lost --------0-----0-----0-----0-----0 Non-H2O ---------0----15----30----45----60 The above data reflect what has been seen in a number of studies - that weight is (illogically in caloric terms) lost quickly initially on an Atkins diet, but that weight lost after twelve months is about the same. If such a study were to show the above - and in my opinion the logic emphatically suggests that is, approximately, what it would show - then which diet do you think stands a decent chance of showing sustained weight loss after twelve months? It really is a bit pie-in-the-sky to imagine that people can eat as many calories as they want of high fat foods and lose all the weight they want. As it turns out, though, dehydration has been a spectacularly successful marketing tool. JMO.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 Hi folks: My view of Atkins is that a study needs to be done to assess the COMPONENTS of weight lost on both a Pritikin diet and an Atkins diet. We all know of people who have gone on an Atkins diet, have been eating huge numbers of calories and have quickly lost appreciable weight. Most of us here, hopefully, know that this does not make a lot of sense. We know that a pound of body weight is associated with about 3500 calories. So it is clear that on an Atkins diet the quick initial weight loss is not real, caloric, weight but something else. The logic of the situation suggests the following: Dr. Atkins unfortunate experience in hospital confirms (even according to the accounts of the Atkins Nutritionals people) that when someone who has been on the Atkins diet reverts to a diet that includes normal amounts of electrolytes and carbohydrates, sixty pounds of weight can be added in very short order - in Dr. Atkins case less in than two weeks I believe? Clearly, this is not real caloric weight. It is water. Similarly, this very strongly suggests that the weight loss experienced in the early stages of an Atkins diet is not real caloric weight either - how could it be with the huge caloric intake? The weight loss that appears on the scales is largely, perhaps entirely, accounted for by the dehydration effect of the diet. So my hypothesis is that if such a study were conducted, and the components of weight lost on a (GENUINE) Pritikin diet and an Atkins diet were compared, then the following is approximately what would be found (I hope the formatting works out in the following table - this is not a great medium for communicating tabular information): COMPONENTS OF WEIGHT LOST ON TWO DIET TYPES ------------------------------------------- Months >>> -----0-----3-----6-----9-----12 -------------- --- · --- · --- · --- · --- Atkins: Total wt ------250---210---190---190---190 H20 lost -------0-----40----60----60----60 non-H20 --------0------0-----0-----0-----0 Pritikin: Total wt ------250---235---220---205---190 H2O lost --------0-----0-----0-----0-----0 Non-H2O ---------0----15----30----45----60 The above data reflect what has been seen in a number of studies - that weight is (illogically in caloric terms) lost quickly initially on an Atkins diet, but that weight lost after twelve months is about the same. If such a study were to show the above - and in my opinion the logic emphatically suggests that is, approximately, what it would show - then which diet do you think stands a decent chance of showing sustained weight loss after twelve months? It really is a bit pie-in-the-sky to imagine that people can eat as many calories as they want of high fat foods and lose all the weight they want. As it turns out, though, dehydration has been a spectacularly successful marketing tool. JMO.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 Rodney Some comments 1) Why do you beleive people eat an huge number of calories on Atkins and lose weight? Do you have any evidence for the " huge number of calories " ? I dont. And we do know that people overestimate their caloric intake by around 50%. In the studies, they didnt track calories, and when they did, they ate less. In one study during phase one of Atkins, caloric consumption went down 1000 calories per day (2400 to 1400). During the second phase, caloric consumption went up only another 100 calories from where they were in phase one (1400 -1500).. I think the assumption, based on the ability to eat all the meat, cheese, butter, etc you want, is that caloric intake goes up. What people fail to realize is that while it sounds like you can do what you want. People dont. And, as Tony regularly points out, you cant violate the laws of thermodynamics. 2) The human body stores glucose as glycogen. To do so, each glucose molecule is combined with water to form the glycogen. The glycogen molecule is 3 parts water and 1 part glucose. So, to store glucose also means to store water. When the glycogen is released from storage so is the water weight associated with it. If you do the math based on how muc glycogen the average human can store, (around 2000 calories or more depending on the size of their muscles), and do the conversions, it equates to about 4-6 lbs of water for the average person. So, in one of the studies on the Atkins diet, during the first 2 weeks, the Atkins dieters lost 8 lbs. During the next 2 weeks they lost only 2 lbs. WHere did the extra 6 come from in the first 2 weeks when everything else was kept constant? This is why bodybuilders who are competing and want to look very " cut " will cut out all carbs the week or so before. It removes any " puffiness " from thier muscles and body from the storage of the glucose and water as glycogen. They also reduce water intake to as little as possible (and risk electrolyte imbalances and heart arrythmias). Now, the opposite is true also. Stay on Atkins for a while and remain carb free and glycogen depleted. Then, go out to eat and have a typical meal of pasta with some bread (maybe due to boredom or craving). The body literally sucks up the carbs to store them replacing the lost glycogen. The next morning the unsuspecting dieter gets on the scales and sees a 4-6 lb weight gain and says " AHA, Dr Atkins was right, I never should have eaten the pasta as I am allergic (or sensitive) to carbs!! 3) Lets look at a real life analogy... A typical American goes out to eat an a typical American restaurant and orders their typical American meal. They are fat and decided to lose weight and now go on Atkins. Lets see what happens.... Typical American Meal... Some Bread (with lots of butter and or olive oil) Appetizer of some Potato Skins or Fried Onion or Mushrooms Salad With Blue Cheese Dressing Dinner Plate Steak with garlic butter Loaded Baked Potatoe (with sour cream, butter, bacon bits) Broccoli with butter or hollandaise OF if they might get a dish of fettucine alfredo with chicken Soft Drink (or two) Cheesecake But, now they go on Atkins. They cant have the bread but that also means they cant have the butter and or olive oil. Beleive it or not, most of the calories came from the butter and olive oil but without the bread, they dont have a delivery system for it. Unless they use their fingers which most people wont. They cant have carbs, so they cant have the potato skins or the blomming onion. But, they can have a shrimp cocktail. For dinner, they can still have the steak and the garlic butter. They cant have the potato, which means that they also cant have the sour cream, the butter and the bacon bits, which, beleive it or not, contribute 2/3 of the calories of the loaded potatoe. Again, the potato was a delivery system for all the fatty stuff. They can have the broccoli with the butter and or hollandaise sauce. The cant have a soft drink so they get a diet drink They cant have the cheesecake (too much sugar) so they go with a sugar free Atkins cheesecake., Now, you tell me, what happens to the caloric intake? This demonstration was actually shown live in a restaurant on 20/20 or one of the news shows. The reporter was comparing what he used to eat on his low fat diet (oy veh) to his new atkins diet and how it helped him lose weight by cutting the carbs. I am sure he didnt realize what he was really doing (or cutting) nor did most of the viewers. People think by eating more of the Atkins recommended foods they are getting in more calories, but usually they are not, and thats how they lose weight. When you look at calorie density, Atkins forbids the source of the most calorie dense foods in the American diet (foods high in white flour, and/or white sugar, which also come loaded with oils) and allows you to replace them with foods that are not as calorie dense (meat, seafood, chicken, etc). In American, starches, like bread, potato, etc are really just delivery systems for fat. You not only remove the delivery system but you also remove a LOT of fat and then you are left with eating more animal protein, which isnt as high in calories. In American right now, about 50% of the diet is carbs and 90% of that is refined carbs. Only about 15% of the diet is protein and 35% fat. Remove all the carbs, except a few servings of salad and veggies a day, and all the hydrogenated fats and eat more protein and some more fat, you are still at a caloric deficit. And, even though he allows it, you cant live on butter, oil, cheese, etc without getting side effects, like constipation, headaches etc as most of the particpants in his studies found out. And, in spite of the " appeal " of the diet, in the studies, over 50% of the people on the Atkins diet in the studies dropped out. So, I guess it wasnt to appealing. The good news about Atkins, he encouraged the elimination of all the refined carbs in the American diet The bad news, he encouraged people to replace them with animal protein and fat. S Beach went one step better by recommending only " healthier " versions of animal protein and fat. But, we can all go even one step futher, eliminate all the refined carbs and replace them with lots of the lowest calorie dense, highest nutrient dense, most satiating foods, fruits, vegetables, whole grains, starchy vegetables ane legumes.

Pretty soon I start thinking that eating is disgusting. Now, I've always done it in a pretty strange way, since I was a vegetarian for a long time and won't eat much meat, even under those circumstances. Lots of canned black soybeans... I've generally tried to get a lot of non-grain fiber (kale, above mentioned soybeans) but find I get constipated anyway. Ketogenic diets kick in many of the metabolic changes that happen with fasting. And one thing about fasting is that much of the hunger goes away after the second day -- at some point your brain realizes that it's not going get any food and it isn't worth ringing the alarm bells. Some advocates of ketogenic diets claim that this mechanism reduces hunger on a ketogenic diet. > This is why bodybuilders who are competing and want to look very " cut " will cut out all carbs the week or so before.

To be a winning bodybuilder, you need to put on massive amounts of muscle but have very low (<< 10%) body fat. There have always been two schools of thought about this: the Schwarzenegger school is to gorge yourself most of the year, then starve yourself for a month or two before competition season. Others, such as Zane and Gironda, advocate not having such an extreme cycle, but trying to keep body fat low consistently. In recent years, the Schwarzenegger school has been dominant, and lately we've seen bodybuilders who wash down 10,000 calories a day with their anabolic steroids in the " on " season. This might not be good for your health, but bodybuilding lore holds that the ketogenic diet is effective for losing fat mass while losing a minimum of muscle mass.

In one study during phase one of Atkins, caloric consumption went down 1000 calories per day (2400 to 1400).

Pretty soon I start thinking that eating is disgusting. Now, I've always done it in a pretty strange way, since I was a vegetarian for a long time and won't eat much meat, even under those circumstances. Lots of canned black soybeans... I've generally tried to get a lot of non-grain fiber (kale, above mentioned soybeans) but find I get constipated anyway. Ketogenic diets kick in many of the metabolic changes that happen with fasting. And one thing about fasting is that much of the hunger goes away after the second day -- at some point your brain realizes that it's not going get any food and it isn't worth ringing the alarm bells. Some advocates of ketogenic diets claim that this mechanism reduces hunger on a ketogenic diet. > This is why bodybuilders who are competing and want to look very " cut " will cut out all carbs the week or so before.

To be a winning bodybuilder, you need to put on massive amounts of muscle but have very low (<< 10%) body fat.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 It's been a while since I got to rant that macro-nutrient ratios don't matter (IMO). While I won't comment on or attempt to extrapolate too much from reports surrounding Dr. Atkins unfortunate accident and death I will make one general observation about his popular diet. I suspect glycogen is the key to the early rapid water weight loss. Glycogen the sugar equivalent energy stored by the body in muscles and elsewhere for immediate energy is bound with water. Ketosis, or the all fat low/zero carbohydrate metabolism depletes the body's glycogen stores... This will result in a pretty rapid weight drop as water is unbound and released. This rapid early weight loss is useful to provide some positive reinforcement to motivate dieters. It is not very useful for stable, long term weight management. Calories do count, how much I still don't know, but as usual if something sounds too good to be true, it probably is.

There is plenty of scientific evidence and it could be called the " High Fiber, Moderate Lean Protein, Moderate Omega-3 Fat " diet. There's also plenty of scientific evidence that a high saturated fat, high protein diet that Atkins recommends is very unhealthy long-term. IMHO, the only reason Atkin works for some people is due to the 25% average calorie loss due from thermogenesis of protein. It seems to me to be all about a food volume/satiety issue and high fiber diet works just as well, if not better/safer.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 Hi Jeff: OK, I take your point. I had in mind people I know who have told me they think Atkins is wonderful because they can eat as much as they want of foods they like, and have lost quite a bit of weight. But they did not tell me, and I bet they didn't measure, what the change was in their caloric intake. It is also a very relevant point that eliminating the simple carbohydrates eliminates the 'delivery system' for a lot of calories. Thanks.

When Atkins first pushed the ketogenic diet in the 1970's, a ketogenic diet was basically a whole foods diet. It meant avoiding most of the junk at family parties, and avoiding the vending machine at work. Around 2000, we saw an explosion in " low-carb " junk food filled with sugar alcohols and spiked with sucralose. The high price of these products alone keeps them out of vending machines.

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 No argument with Jeff's ideas (tirade? ha) on Atkin's diet. Herman Taller said he used safflower oil, in addition to what he ate, but he did have a reasonable diet, like cut out the high calorie carbos. "Calorie Don't count" (pre Atkin's). BUT he described himself as being a heavy 250#, - a lightweight, IMO. Maybe he cured his metabolic syndrome? Regards. RE: [ ] Re: Atkins diet - pros and cons. RodneySome comments1) Why do you beleive people eat an huge number of calories on Atkins and lose weight? Do you have any evidence for the "huge number of calories"? I dont. And we do know that people overestimate their caloric intake by around 50%. In the studies, they didnt track calories, and when they did, they ate less. In one study during phase one of Atkins, caloric consumption went down 1000 calories per day (2400 to 1400). During the second phase, caloric consumption went up only another 100 calories from where they were in phase one (1400 -1500)..I think the assumption, based on the ability to eat all the meat, cheese, butter, etc you want, is that caloric intake goes up. What people fail to realize is that while it sounds like you can do what you want. People dont. And, as Tony regularly points out, you cant violate the laws of thermodynamics.2) The human body stores glucose as glycogen. To do so, each glucose molecule is combined with water to form the glycogen. The glycogen molecule is 3 parts water and 1 part glucose. So, to store glucose also means to store water. When the glycogen is released from storage so is the water weight associated with it. If you do the math based on how muc glycogen the average human can store, (around 2000 calories or more depending on the size of their muscles), and do the conversions, it equates to about 4-6 lbs of water for the average person. So, in one of the studies on the Atkins diet, during the first 2 weeks, the Atkins dieters lost 8 lbs. During the next 2 weeks they lost only 2 lbs. WHere did the extra 6 come from in the first 2 weeks when everything else was kept constant? This is why bodybuilders who are competing and want to look very "cut" will cut out all carbs the week or so before. It removes any "puffiness" from thier muscles and body from the storage of the glucose and water as glycogen. They also reduce water intake to as little as possible (and risk electrolyte imbalances and heart arrythmias). Now, the opposite is true also. Stay on Atkins for a while and remain carb free and glycogen depleted. Then, go out to eat and have a typical meal of pasta with some bread (maybe due to boredom or craving). The body literally sucks up the carbs to store them replacing the lost glycogen. The next morning the unsuspecting dieter gets on the scales and sees a 4-6 lb weight gain and says "AHA, Dr Atkins was right, I never should have eaten the pasta as I am allergic (or sensitive) to carbs!! :)3) Lets look at a real life analogy... A typical American goes out to eat an a typical American restaurant and orders their typical American meal. They are fat and decided to lose weight and now go on Atkins. Lets see what happens....Typical American Meal...Some Bread (with lots of butter and or olive oil)Appetizer of some Potato Skins or Fried Onion or MushroomsSalad With Blue Cheese DressingDinner Plate Steak with garlic butterLoaded Baked Potatoe (with sour cream, butter, bacon bits)Broccoli with butter or hollandaiseOF if they might get a dish of fettucine alfredo with chickenSoft Drink (or two)CheesecakeBut, now they go on Atkins.They cant have the bread but that also means they cant have the butter and or olive oil. Beleive it or not, most of the calories came from the butter and olive oil but without the bread, they dont have a delivery system for it. Unless they use their fingers which most people wont. :)They cant have carbs, so they cant have the potato skins or the blomming onion. But, they can have a shrimp cocktail. For dinner, they can still have the steak and the garlic butter. They cant have the potato, which means that they also cant have the sour cream, the butter and the bacon bits, which, beleive it or not, contribute 2/3 of the calories of the loaded potatoe. Again, the potato was a delivery system for all the fatty stuff. They can have the broccoli with the butter and or hollandaise sauce.The cant have a soft drink so they get a diet drinkThey cant have the cheesecake (too much sugar) so they go with a sugar free Atkins cheesecake.,Now, you tell me, what happens to the caloric intake?This demonstration was actually shown live in a restaurant on 20/20 or one of the news shows. The reporter was comparing what he used to eat on his low fat diet (oy veh) to his new atkins diet and how it helped him lose weight by cutting the carbs. I am sure he didnt realize what he was really doing (or cutting) nor did most of the viewers.People think by eating more of the Atkins recommended foods they are getting in more calories, but usually they are not, and thats how they lose weight.When you look at calorie density, Atkins forbids the source of the most calorie dense foods in the American diet (foods high in white flour, and/or white sugar, which also come loaded with oils) and allows you to replace them with foods that are not as calorie dense (meat, seafood, chicken, etc). In American, starches, like bread, potato, etc are really just delivery systems for fat. You not only remove the delivery system but you also remove a LOT of fat and then you are left with eating more animal protein, which isnt as high in calories.In American right now, about 50% of the diet is carbs and 90% of that is refined carbs. Only about 15% of the diet is protein and 35% fat. Remove all the carbs, except a few servings of salad and veggies a day, and all the hydrogenated fats and eat more protein and some more fat, you are still at a caloric deficit. And, even though he allows it, you cant live on butter, oil, cheese, etc without getting side effects, like constipation, headaches etc as most of the particpants in his studies found out. And, in spite of the "appeal" of the diet, in the studies, over 50% of the people on the Atkins diet in the studies dropped out. So, I guess it wasnt to appealing.The good news about Atkins, he encouraged the elimination of all the refined carbs in the American dietThe bad news, he encouraged people to replace them with animal protein and fat. S Beach went one step better by recommending only "healthier" versions of animal protein and fat.But, we can all go even one step futher, eliminate all the refined carbs and replace them with lots of the lowest calorie dense, highest nutrient dense, most satiating foods, fruits, vegetables, whole grains, starchy vegetables ane legumes.RegardsJeff Quote Link to comment Share on other sites More sharing options...

Guest guest Posted February 2, 2006 Report Share Posted February 2, 2006 Thanks, Logan, Agree with your observation, because there are CRONies who do a high fat and swear by it because of BG problems. They don't post much but they're out there. In any case, they don't do a LOT of kcals (this is a low cal group), so I think it's possible to do a high fat diet IF it's OTO of 1800 kcals. They would simply burn it daily. I can't do Atkin's, but then I'm not a high BG, either. Regards.

There's also plenty ofscientific evidence that a high saturated fat, highprotein diet that Atkins recommends is very unhealthylong-term.IMHO, the only reason Atkin works for some people isdue to the 25% average calorie loss due fromthermogenesis of protein. It seems to me to be allabout a food volume/satiety issue and high fiber dietworks just as well, if not better/safer. Logan Quote Link to comment Share on other sites More sharing options...
