What popular diet plan helps you lose more Weight: the Atkins diet, the Barry Sears zone diet, the oriental diet or the learning program?
To answer this question, the researcher at the University of Stanford Christopher D. Gardner, PhD, and colleagues randomly attributed 311 women overweight and obese to one of the diets. The idea was to see what worked best for weight loss: a very low-carbohydrate diet (Atkins), a low carbohydrate (zone) diet, a low-fat diet and high carbohydrate (learn, based on guidelines US), or a very high diet on carbohydrates (ornes).
Gardner's team has ensured that women understood diets, having an enthusiastic nutritionist teach them their program designated in eight weekly sessions. Then they practically left them to follow the diet books for the rest of the study of the year.What happened?
At the beginning of the study, the mean weight of women was 187 pounds. All of them, Gardner says, needed to lose at least 15 pounds - and many needed to lose 40 to 80 pounds.
After a year, some of the women in each group lost up to 30 pounds. Twice more lost it in the Atkins diet group as in any other group. Overall, here is how much women lost in the four diets:
- Atkins diet - 10.4 pounds on average
- Learn - 5.7 Average Libra
- Ornating diet - 4.85 Average Libra
- Zone Diet - 3.5 Average Libra
The difference in weight loss among women attributed to the Atkins diet and women assigned to the zone diet were statistically significant. The other differences were not - which means they could be finding chance.
Gardner and colleagues report the discoveries in the March 7 edition of the American Medical Association magazine.

What does the results mean? This depends on who you ask.
Gardner says that the study highlights how difficult it is that people follow the zone and the ornes diets on their own.
It points to two American diet trends: we are eating more and more calories. And we are eating more and more refined carbohydrates in the form of sweets, soft drinks and snacks.
It suggests that the Atkins diet offers a simple way to neutralize these trends.
"Dr. Atkins just said," Do not eat any refined carbohydrate, period. "And the carbohydrates you eat should be good and healthy carbohydrates," Gardner tells WebMD. "And this is very attached to the trend that is happening in the US obesity epidemic. Maybe that's why the Atkins diet was a little more effective."Jeff S. Volek, PhD, RD, Assistant Professor of Kinesiology at the University of Connecticut, studied the Atkins diet in a research partially funded by the Atkins Foundation. Volek says Gardner's discoveries extend and confirm earlier surveys.
"OS attributed to the Atkins diet had less carbohydrate intake than the other three groups. Therefore, it is valid to conclude that the differences are due to carbohydrate intake," says Vollek. "We are trying to say that they are carbohydrates that are directing the physiology of weight loss and that we should talk more about carbohydrate restriction than about fat restriction."
But this interpretation is not unanimous.
"What this study showed, once again, is how difficult for people to lose weight, no matter what the approach," Psychology Professor of Yale Kelly D. Brownell, PhD, says WebMD.
BrownNell wrote the Learn Weight Loss Program Manual. Nutrition is only a part of the program, which also aims to help people change interpersonal relationships, improve physical activity, change behaviors and change attitudes.
"The people who try to follow the Atkins diet lost about 10 pounds and others lost about five pounds. No one will be terribly excited about those five extra pounds, since where they started to be in 187 pounds," he says. . "The message is not that atkins is better; it is that nothing works very well for people who are already obese."
Creator Zone Diet Barry Sears, PhD, notes that none of the groups in the Gardner study followed their designated diet plans.
"These results have no meaning in the real world or in the world of controlled studies," says WebMD. "This is one of the first times Dean [Orien] and I will agree. Even if Bob Atkins were here, he would say," This is not my diet. "You have the three tenors singing together: 'This is not my diet.'
The attributed to the Atkins diet, he says, actually ate much more foods as recommended in the zone diet."These patients were receiving three times the amount of carbohydrates recommended by the Atkins diet," says Sears. "Until the end of the study, they were eating 140 grams of carbohydrates per day. Bob [Atkins] never recommended more than 50 grams per day. I recommend 100-110 grams of carbohydrates a day. So essentially the Atkins diet was The diet zone in this study. "
As Sears predicted, Dean Orish, MD, agrees that the "original diet" that Gardner study participants followed is not the original diet he created.
"What is frustrating for me is that they were not following a diet, I recommend:" Orish says WebMD. "Dr. Gardner did not test what these diets do; he only tested as they are easy to follow. It's easier to eat bacon and brie than eating healthy foods. But that does not mean it's good for you." / p>. Gardner and colleagues did not weigh women trying to follow the four very different diet plans. They also made blood studies to look for cardiac deserisk factors. "All four groups have benefited for blood pressure and cholesterol and insulin sensitivity levels - all things you would expect from weight loss," says Gardner. "It's good to know that you get these things with modest weight loss. You do not need to lose 100 pounds. If you lose 5% to 10% of your body weight, you get a benefit." orish says it is simply wrong to take over the Gardner study that diet plans are equally healthy. "To say that the Atkins diet is no longer harmful than the original diet is dangerously misleading," he says. "Dr. Gardner and colleagues say that the heart-disease risk factors were comparable in all four diets and then they said that Atkins do not hurt you. But risk factors are only risk factors. In our studies, We measured heart disease itself, not only risk factors. And we find that in the eastern diet, people with heart disease showed a clear reversal after a month, more after a year, and even more after five years. " p> Volek has a very different view. "Reducing carbohydrate intake is a very effective option for losing weight, improving health and reducing symptoms of metabolic syndrome - high blood pressure, high levels of blood fat, low HDL cholesterol levels and insulin resistance," he says. "Reducing carbohydrates is not just an option, but probably the preferred option for people to correct these abnormalities." Gardner says he thinks the main reason why people try to follow the Atkins diet lost more weight is that the diet is easy to understand. WebMD asked Sears and Orish, whether they could summarize their diets in a brief and simple instruction. "For the zone diet, one person needs only one hand and one eye," says Sears. "At each meal, the rest of your life, divide your dish into three equal parts. In one, put a piece of meat, fish, chicken, tofu or low fat protein not widely or thicker than the palm From your hand. And in the other two-thirds of your plate, fill it full of vegetables and fruits. And then take a pinch of monounsaturated and healthy fat. And now you have a meal with the right balance of carbohydrates, proteins and fat. This is how you lose weight - you keep hunger and satiety under control. " Orish says simple changes in the diet help people lose weight and gain health. "These changes are simple," he says. "Eat less total fat. Eat less simple carbohydrates. Try to eat whole foods if you can - predominantly fruits and vegetables and whole grains and legumes in their natural form." Brownnell says that obviously not easy to lose weight, or else all sensible diet plans would work better. "Obesity is a problem that screams to be avoided instead of treated," he says. "We need to start with people when they are children, and we need to work to avoid the problem." 2021 IFBB Clash of the Titans Pro Bikini Results - Weight Loss Camp
