وجدت الدراسة التي أعدها باحثون من جامع يورك إن البالغين في أمريكا عام 2006 ازداد وزنهم مقارنة بمن كانوا في أعمارهم عام 1988، بل حتى مقارنة بمن كان لديهم نفس مستويات التغذية والنشاط البدني.

قارنت الدراسة بين نفس الوجبات الغذائية عام 1971 و1988 و2006، ووجدت أن الأخيرة أثقل بنسبة 5 بالمائة.

بحسب مؤلفة الدراسة البروفيسورة جينفر كوك من جامعة يورك: "إذا كنت في عمر الـ 25، وأكلت طعاماً أقل مما كانوا يأكلون في الماضي، عليك أن تمارس نشاطاً أكثر منهم لتحافظ على الوزن نفسه".

قدمت كوك 3 نظريات لتفسير سبب صعوبة فقدان الوزن الزائد حالياً، الأولى تقول: إن الناس يتعرضون اليوم لمزيد من المواد الكيميائية من خلال البيئة المحيطة بهم. والثانية: أن هناك ارتفاع في معدل استهلاك الأدوية، والثالثة: أن بكتريا الأمعاء لدى الأمريكيين تغيرت مع مرور الوقت، وأن ذلك يجعل الناس عرضة لاكتساب وزن أكثر مع مرور الوقت.

لم تستطع الدراسة تحديد الأسباب الكامنة وراء تزايد صعوبة خسارة الوزن، لكنها رصدت وجود الظاهرة.

استندت الدراسة إلى البيانات الغذائية الخاصة بـ 36377 شخص تم توثيق بياناتهم من خلال المسح الوطني في الولايات المتحدة بين عامي 1971 و2008، وبيانات النشاط البدني الخاصة بـ 14419 تم تسجيلها بين عامي 1988 و2006.

I found the study by researchers from York mosque that adults in America in 2006 increased weight compared with those in the age in 1988, even compared to have the same levels of nutrition and physical activity.The same study compared diets, 1971, 1988 and 2006, found that the heaviest 5 percent.According to the author of the study Professor Jennifer Cook from University of York: "If you're in the age of 25, and eat less food than they eat in the past, you should be more active to maintain weight.Cook provided 3 theories to explain why the difficulty losing excess weight currently, says: people are exposed today for more chemicals through their surroundings. And second: that there is a high rate of consumption of medicines, and third: the bowel bacteria among Americans changed over time, and that makes people more likely to gain weight over time.لم تستطع الدراسة تحديد الأسباب الكامنة وراء تزايد صعوبة خسارة الوزن، لكنها رصدت وجود الظاهرة.استندت الدراسة إلى البيانات الغذائية الخاصة بـ 36377 شخص تم توثيق بياناتهم من خلال المسح الوطني في الولايات المتحدة بين عامي 1971 و2008، وبيانات النشاط البدني الخاصة بـ 14419 تم تسجيلها بين عامي 1988 و2006.

I found the study by researchers from the mosque York that the adults in America in 2006 increased their weight than those who were in the age in 1988, even compared to those who have had the same nutrition and physical activity levels. The study compared between the same diets in 1971, 1988 and 2006, and found that the last heavier by 5 percent. According to the author of the study Professor Jennifer Cook of the University of York: "If you are at the age of 25, and ate less food than they ate in the past, you have to exercise more of them active to maintain the same weight." Cook offered three theories to explain why the difficulty of excess weight loss Currently, the first says that people today are exposed to more chemicals through their environment. And the second: that there is a rise in pharmaceutical consumption rate, and the third: that gut bacteria Americans have changed over time, and that makes people prone to gain weight more with the passage of time. Could not study to determine the reasons behind the increasing difficulty of weight loss, but they spotted the existence of the phenomenon . study was based on special dietary data for 36 377 people have been documenting their data through a national survey in the United States between 1971 and 2008, and data on physical activity b 14419 was recorded between 1988 and 2006.
