Diet was assessed by validated food frequency questionnaires and updated every four years. But replacing animal protein with well-balanced plant proteins is beneficial, and this is in the mainstream of what most scientists who do nutrition research believe. WebIn this video, we are comparing the new Atkins Protein Chips to the Quest Protein Chips. www.atkins.com, All Content Copyright 2014-2019 AtkinsFacts.org, Center for Science in the Public Interest, Low Carb Diets: Potential Short and Long-term Health Implications, Northwestern University School of Medicine, Physicians Comittee for Responsible Medicine, Sudden Cardiac Death of an Adolescent During [Atkins] Dieting, United States Department of Agriculture 1/2, United States Department of Agriculture 2/2, http://hin.nhlbi.nih.gov/atpiii/calculator.asp?usertype=prof. The authors wrote: The beneficial effects of lower protein intake were not seen in those over 65. The decrease in the percentage of calories from fat during the period 1971 to 1991 is attributed to an increase in total calories consumed; absolute fat intake in grams actually increased. I have presented these research findings on several occasions at the annual scientific meetings of the American Heart Association, American College of Cardiology, American Dietetic Association (now the Academy of Nutrition and Dietetics), the Institute of Medicine of the National Academies and many others. Hunninghake DB, Stein EA, Dujovne CA, et al. In other words, the diet I recommend causes weight loss, not weight gain. What is the comparison and contrast of dr.Atkins and dr. Ornish was a physician consultant to U.S. Pres. You can hear some of their stories here. The decrease in HDL-C and apo A-I levels correlated with the decrease in apo A-I transport rate but not with the increase in apo A-I FCR. The Framingham risk score is calculated from age, sex, total cholesterol, HDL, smoking, and systolic blood pressure (46). Ornish then moved to the Boston area for a clinical fellowship at Harvard Medical School and an internship and residency in internal medicine at Massachusetts General Hospital, which he completed in 1984. In addition to fiber, complex carbohydrates and whole foods are rich in phytochemicals, bioflavonoids, carotenoids, retinols, sulforaphanes, isoflavones, and polyphenols and other substances that may reduce the risk of many chronic diseases. Dietary cholesterol and the pathogenesis of atherosclerosis. The effects of weight loss on the activity and expression of adipose-tissue lipoprotein lipase in very obese humans. 1968;2:702-703. A case report in a peer-reviewed journal described the fatal ventricular fibrillation arrest of a 16-year-old girl who had started a high-protein/low-carbohydrate diet 2 weeks earlier and presented profound hypokalemia and hypocalcemia during resuscitation attempts (54). Even better would be to reduce the intake of simple carbohydrates and most fats, which results in losing even more weight while enhancing health rather than potentially harming it. As Moyer indicates here, the 2014 meta-analysis showed higher mortality risks associated with both processed meat and unprocessed meats. As you approach your weight loss goals, you start to His famous 1990 Lifestyle Heart trial involved a total of 48 patients with heart disease. Melinda Wenner Moyer, a contributing editor at Scientific American, is author of How to Raise Kids Who Arent Assholes: Science-Based Strategies for Better Parentingfrom Tots to Teens (G. P. Putnams Sons, 2021). Companies such as McDonalds consulted him on the formulation of healthier foods, and he held lucrative positions on the advisory boards of PepsiCo and Safeway. The effect of high-protein diets on coronary blood flow. It found that individuals assigned to eat high-fat (41 percent calories from fat), Mediterranean-style diets for nearly five years were about 30 percent less likely to experience serious heart-related problems compared with individuals who were told to avoid fat. New York: McGraw Hill; 2002. Outcomes were assessed at months 0, 2, 6, and 12. Other large observational studies have found that diets high in fat and protein are not associated with disease and may even protect against it. Only total cholesterol and HDL changed in this study, so these were the only factors in determining the risk score. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. By planning to improv Medicare followed suit in 2006. In our debates, Dr Atkins often claimed that his diet can reverse coronary heart disease (CHD) but never published any peer-reviewed data to support this assertion, nor has anyone else, including advocates of similar diets such as the Zone and the South Beach diets (34). Analyses of all pairwise differences by the Tukey standardized range test (<.05) indicate that the Atkins diet group was significantly different than all other diet groups at 2 and 6 months and that the Atkins diet group was significantly different than the Zone diet group at 12 months. Intensive risk factor modification. The concept of a dietary spectrum empowers people with information and freedom of choice rather than the feeling of constraint or restriction. Hemorheologic effects of a short-term ketogenic diet. Dr. Atkins and Dr. Dean Ornish Finally Agree - Eating to Fuel Health And Im not aware of any studies showing that walking and stress management techniques alone can reverse heart disease. In contrast, within each diet, the HDL-C and apo A-I levels were inversely correlated with apo A-I FCR both on the high-and low-fat diets but not with apo A-I transport rate (44). Unfortunately, most studies of the Atkins diet and other highprotein diets measure only risk factors for CHD such as weight and lipids. I would love to be able to tell you that these are health foods, but they are not. Whole-grain intake and the risk of type 2 diabetes: a prospective study in men. Ornish first takes issue with the data I cite on food consumption patterns from the National Health and Nutrition Examination Survey (NHANES). Circulation. Dean Ornish, MD, is founder and president of the non-profit Preventive Medicine Research Institute and is Clinical Professor of Medicine at the University of California, San Francisco. It found that individuals assigned to eat high-fat (41 percent calories from fat), Mediterranean-style diets for nearly five years were about 30 percent less likely to experience serious heart-related problems compared with individuals who were told to avoid fat. Founder and president, Preventive Medicine Research Institute Several studies that used serial coronary arteriography to assess CHD patients who were consuming a conventional 30% fat diet revealed that the majority showed progression (worsening) of coronary atherosclerosis (22,36). Dansinger ML, Gleason JL, Griffith JL, Li W, Selker HP, Schaefer EJ. For instance, he wrote that animal proteins have been associated with higher disease and mortality risks in observational studies. The title is confusing and potentially harmful to many readers. 1990;85:144-151. A critique of the diet guru's views on high-protein diets, followed by a response from Ornish and a reply from the author. 2001;73:1010-1018. In contrast, there was a statistically significant reduction in LDL-cholesterol in the Ornish group but not in the Atkins group after one year. Pres. In doing large-scale studies in which people complete dietary surveys, there is often so much noiseespecially in combining data in meta-analysesthat a type 2 error often occurs (that is, the noise obscures the ability to detect statistically significant differences). An Atkins diet often shows a greater reduction in triglycerides by comparison. USDA data also show (pdf) that between 1970 and 2005 U.S. consumption of saturated fatrich butter and lard as well as hydrogenated shortening decreased 17 percent. N Engl J Med. You can eat fewer calories by consuming less food. The USDA tracks changes in consumption of the entire food supply. Only patients following the Atkins diet showed a worsening of each CVD risk factor (LDL-C, triglycerides, total cholesterol, HDL-C, total-to-HDL cholesterol ratio, homocysteine, Lp(a), and fibrinogen), despite achieving statistically significant weight loss. 2000;51:817-826. Interaction of dietary cholesterol and triglycerides in the regulation of hepatic low-density lipoprotein transport in the hamster. To understand better the mechanism of this phenomenon, Breslow and colleagues studied the turnover of HDL apolipoproteins (apo) A-I and A-II in 13 subjects on two contrasting metabolic diets. Prev Cardiol. 2002;113:30-36. His dietary regimen was mostly an inverted version of the USDA pyramid that was high in fat and low in carbohydrates. To some, the fact that an Atkins diet does not significantly raise LDL-C is surprising given the amount of saturated fat and cholesterol in the diet. Ornish also dismisses the randomized controlled trials I cited in large part because the subjects in these trials did not adhere to the diets and reduce their fat intake enough. Stefanick ML, Mackey S, Sheehan M, et al. Well, thats the pointwere not fat because were eating too little fat; were fat because were eating too much of everything. INTERVENTION: In a survey of food consumption data from the United States Department of Agricultures National Food Consumption Surveys (NFCS) and the Continuing Survey of Food Intakes by Individuals (CSFII), Individuals of all ages who consume a diet with fewer than 30% of calories from fat consistently have lower energy intakes. Could it be that our attempts to reduce fat have in fact been part of the problem? Bushinsky DA, Chabala JM, Gavrilov KL, Levi-Setti R. Effects of in vivo metabolic acidosis on midcortical bone ion composition. Insulin stimulates 3-hydroxy-3-meth-ylglutaryl coenzyme A reductase (which statin drugs inhibit), increasing lipid production, which may help to explain why high-protein diets do not always exacerbate hypercholesterolemia (26). So when Ornish wrote in his oped that for reversing disease, a whole-foods, plant-based diet seems to be necessary, he is incorrect. Clinical professor of medicine, University of California, San Francisco Foster GD, Wyatt HR, Hill JO, et al. Wing RR, Vazquez JA, Ryan CM. Westman EC, Yancy WS, Edman JS, et al. CA Cancer J Clin. Journal of the American Medical Association 104(2004):537. Atkins vs. Ornish: The Fight Over Fat | by Simon & Schuster | Game Twenty-eight were assigned to his low-fat, plant-based diet and 20 were given usual cardiac care. Clinical Trials in Cardiovascular Disease. Dean Ornish, MD, is founder and president of the non-profit Preventive Medicine Research Institute and is Clinical Professor of Medicine at the The March 2014 study that Ornish cites as finding a 75 percent increase in premature deaths from all causes and a 400 percent increase in deaths from cancer and type 2 diabetes among heavy consumers of animal protein under the age of 65, also did not distinguish between types of animal protein. These are not theoretical discussions; they are real people who have shown substantial improvements in their health and well-beingnot just in risk factors but also in the underlying disease process. A paper was presented from Tufts University titled One Year Effectiveness of the Atkins, Ornish, Weight Watchers, and Zone Diets in Decreasing Body Weight and Heart Disease Risk. The researchers concluded All diets resulted in significant weight loss from baseline and all but the Ornish diet resulted in significant reductions in the Framingham risk score (45). In other words, when you change the type of food, you dont have to be as concerned about the amount of food. The reduction in HDL-C that may occur on a low-fat diet is another example of a half-truth that is confusing to many people. If anything, our attempts to eat less fat in recent decades have made things worse. 1993;328:1213-1219. Its hardly surprising that quitting smoking, exercising, reducing stress and dietingwhen done togetherimproves heart health. Total cholesterol decreased much more on the Ornish diet than on any of the other diets. Both eating plans recommend avoiding saturated fat from animal proteins and full-fat dairy. They write new content and verify and edit content received from contributors. After multivariate adjustment for major lifestyle and dietary risk factors, the pooled hazard ratio (HR) (95 percent CI) of total mortality for a one-serving-per-day increase was 1.13 (1.071.20) for unprocessed red meat and 1.20 (1.151.24) for processed red meat. The purpose of this article is to find common ground among seemingly contradictory information about different diets, present an evidence-based rationale for optimal nutrition, and describe many of the half-truths and distortions of the Atkins diet and other similar diets. Dietschy JM, Brown MS. Effect of alterations of the specific activity of the intracellular acetyl CoA pool on apparent rates of hepatic cholesterogenesis. Im not cherry-picking data; Im looking at the preponderance of evidence from many studies by leading investigators such as those at Harvard School of Public Health. Goldstein JL, Brown MS. Cholesterol and cardiovascular disease. The point is, its possible to cherry-pick observational studies to support almost any nutritional argument. In his lengthy reply to my article Dean Ornish says I distort his beliefs, cite questionable studies and dont have the clinical experience to assess nutritional evidence. They should not be used to make claims about cause and effect; doing so is considered by nutrition scientists to be inappropriate and misleading. The reason: People who eat a lot of animal protein often make other lifestyle choices that increase their disease risk, and although researchers try to make statistical adjustments to control for these confounding variables, as theyre called, its a very imperfect science. But heres the thing: The patients who followed his diet also quit smoking, started exercising and attended stress management training. 2003;26:302-307. The March 2014 study in Cell Metabolism did distinguish between animal protein and plant-based proteins. 1999, and In: Braunwald E, ed. Kennedy ET, Bowman SA, Powell R. Dietary-fat intake in the U.S. population. Whole foodssuch as whole grain products and fruits and veggiesare healthy, but I think that dairy products, fish and lean cuts of meat or poultry can also be part of a healthy diet, Steffen says. 1986;232:34. 2001;291:2536-2545. For someone trying to reverse heart disease, for example, the diet needs to be rather strict to accomplish this. If you know or suspect that you have a health problem, consult a health professional. The editor of JAMA Internal Medicine invited me to write an accompanying editorial for this study. In: Hennekens C, Manson J, eds. As all dietetics professionals know, there is no mystery in how to lose weight: burn more calories and/or eat fewer calories. Believing this, many people are throwing up their hands, exasperated, saying, These damn doctors cant make up their mindsto hell with them, Ill eat whatever I want, when there is actually an emerging consensus among scientists and physicians who do research in nutrition about what constitutes an optimal way of eating. SUBSTITUTE SIMPLE WITH COMPLEX CARBOHYDRATES. The fact is, individuals on his diet are supposed to consume (pdf) no more than 10 percent of calories from fat, and thats very, very low compared to the average Americans adults intake of 33 percent of calories from fat. Fiber also slows the absorption of food, thereby preventing blood glucose from rising too rapidly and reducing insulin surges. All three diets reduced blood pressure, total and low-density lipoprotein cholesterol levels, and estimated coronary heart disease risk. Ornish D, Pettengill E, Merritt-Worden T. Marked improvements in biomedical and psychosocial cardiac risk factors from a community-based lifestyle program. But they dont mask the truth; compared with individual studies, they get closer to it. Hu JF, Zhao XH, Parpia B. Dietary intakes and urinary excretion of calcium and acids: A cross-sectional study of women in China. This is not true, as I wrote about years ago in my Newsweek column. There has been a recent resurgence of interest in low-carbohydrate/high-fat diets such as the Atkins diet (1-3). Robert Atkins debates Dean Ornish and John McDougall on whether a low-carb, high-protein diet is This does not confer the same risk of atherosclerosis as in Americans with low HDL levels who are consuming a high-fat diet (41). Dean Ornish, MD As for Ornishs contention that the risk of premature death from all causes is higher in those eating red meat than those who do not, I disagree, because the 2014 meta-analysis of 13 studies that I discussed did not find this to be true. Liu S, Stampfer MJ, Hu FB, et al. Question 9 options: her bones and muscles her heart and lungs her flexibility her physical 1999;277:F813-F819. A 2014 meta-analysis similarly reported much higher mortality risks associated with processed meat compared with red meat consumption and found no problems associated with white meat. Dietary fat intake as risk factor for the development of diabetes: Multinational, multicenter study of the Mediterranean Group for the Study of Diabetes (MGSD). Insulin accelerates the conversion of calories into triglycerides, which may contribute to hypertriglyceridemia. Other studies have documented that an AHA/NCEP diet is not very effective in lowering LDL-C (21). 1998;318:549-557. A low-fat diet decreases high density lipoprotein (HDL) cholesterol levels by decreasing HDL apolipoprotein transport rates. I am not against all forms of animal protein. And the 10 percent reduction in carbohydrate in the higher protein diet and the higher unsaturated fat diet was achieved by replacing some fruits with vegetables, reducing sweets and using smaller portions of refined grain products. WebDean Ornish and Dr. T. Colin Campbell have conducted research and published books that suggest a "Whole Food Plant-Based" (WFPB) diet is best for achieving optimal health. 2002;75:848-855. Although Dr Atkins and I agreed on the diagnosisthat many Americans eat too many simple carbohydrateswe disagreed about the prescription. Am J Clin Nutr. Thus, dietary fat is not responsible for obesity. In fact, per capita consumption of fat has risen by 10 Ib/year since 1975, whereas per capita consumption of simple carbohydrates has increased even more, by 20 Ib/year (5). Dr Atkins advocated substituting simple carbohydrates with high-fat, high-animal protein foods such as bacon, sausage, butter, steak, pork rinds, and brie. Pereira MA, Jacobs DR Jr, Pins JJ, et al. Ornish D, Brown SE, Scherwitz LW, et al. N Engl J Med. Its not just 48 patients. Participants were randomly assigned to follow the Atkins (n = 77), Zone (n = 79), LEARN (n = 79), or Ornish (n = 76) diets and received weekly instruction for 2 months, then an additional 10-month follow-up. In another study, 100 people were randomly assigned to one of four diets for 1 year: an Atkins diet; a 30% fat diet; a 15% fat, calorie-controlled diet; or a 10% fat, whole foods diet with an emphasis on complex carbohydrates. (1980) in internal medicine from Baylor College of Medicine in Houston. Leaf A, Weber PC. WebNo two doctors represent opposite sides of THE DIET WAR spectrum better than Dr.s Atkins and Ornish. If you would like to visit their site, please use Whole-grain consumption and risk of coronary heart disease: results from the Nurses Health Study. In my numerous debates with Dr Atkins, we agreed that many Americans eat excessive amounts of processed foods high in simple carbohydrates, including sugar, high-fructose corn syrup, white flour, white rice, and alcohol. WebWas Dr. Atkins Right? Brody J. 1999;18:207-212. What is missing in Moyers article is the clinical experience that comes from helping people change their diet and lifestyle. You may lose weight and start to attract people to you, but, when they get too close, it may be counterproductive. That is why you can lose weight on any diet that restricts portion sizes, but it is hard to keep it off because you may feel hungry and deprived.
