Four out of ten women who diet end up heavier than when they started watching their waistline, a study revealed today.
今日发布的一项研究显示，十分之四的节食女性结果比她们刚减肥的时候还胖。
The research also showed that a large percentage of women start noticing the pounds creeping（爬行，缓慢地移动） back on just 21 days after reaching their ideal weight.
Yesterday, Dr Ian Campbell of the Jenny Craig weight management programme said: \'In the UK 61.4 per cent of adults are overweight or obese.
\'Succeful weight management requires a long-term commitment in order to lose weight succefully and for good.\'Dieting can be a real challenge so setting realistic goals and remaining focused on them is important.
\'Otherwise as this research shows, women could end up heavier than when they started.\'
The \'Food: Body: Mind\' report was commiioned（委任） by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviours around weight lo.
Six in ten said they are currently on a diet and one in five women saying they are on a \'continuous diet\'.
It found the most common triggers to start dieting was seeing their \'reflection in the mirror\', preparing for a summer holiday or unflattering（准确无误的，坦率的） photos posted on social networking sites.
Other popular reasons include comments by friends or relatives or remarks from their other half.
However the study showed that one in ten fall off the wagon（四轮马车，货车） within one day, while almost a fifth manage to make it to a week or more.The average is ten days.
Many blamed preure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal.
Others blamed colleagues, who tuck into（大吃） fatty lunches and snacks unaware of the effect it has on the dieter, while mothers who polish off（草草完成，打败） their children\'s leftovers（吃剩的食物，遗留） was another common cause of weight gain.
Israeli start-up firm Tawkon has developed software to measure mobile telephone handset radiation aimed at helping users reduce exposure to emiions without giving up their phones.
以色列新兴企业陶肯公司最新研发出一款手机辐射监测软件，使用户既不需要停止使用手机，又可以减少被辐射。
A Tawkon employee demonstrates their software on an iPhone in the basement of their offices in Herzliya, September
2, 2010.
Tawkon\'s (pronounced talk-on) application is already available for Research In Motion\'s BlackBerry handsets and will be launched for Nokia\'s Symbian later this year.
\"We are the first solution that can be downloaded to a phone,\" Tawkon co-founder and CEO Gil Friedlander told the reporters.Until now radiation emiions were measured with an external device.
In many countries handset manufacturers must disclose（公开，揭露） the maximum level of radiation emitted and similar legislation is starting to appear in the United States, Friedlander said.
The application monitors the phone user and if radiation levels reach a certain threshold（门槛，极限） called the \"red zone\" an alert is emitted along with suggestions to minimize exposure.
\"There are simple things you can do such as changing the phone\'s position from horizontal to vertical,\" Friedlander said.On many phones the antenna（天线，触角） is on the bottom and often covered by the user\'s hand, causing the phone to emit more radiation.Connecting an ear piece or switching on speakerphone will reduce radiation exposure.In addition, Tawkon is connected to GPS and the software will show users where to move to reach a \"green zone\" and reduce exposure.
\"We don\'t want people to stop using phones but to use them more responsibly,\" the Canadian-born Friedlander, 44, said.
San Francisco became the first U.S.city to pa a law requiring retailers to post radiation levels on cell phones and Friedlander said he believes Tawkon will benefit from this increased awarene.
\"It will take a few years until research (on the health effects of cell phone radiation) will be more conclusive（决定性的，最后的） ,\" Friedlander said.\"A lot of regulatory bodies are concerned this will be too late for a whole generation.To take precautionary measures（预防措施） is the right thing to do.\"
God did not create the universe and the \"Big Bang\" was an inevitable consequence of the laws of physics, the eminent British theoretical physicist Stephen Hawking argues in a new book.
英国著名理论物理学家史蒂芬·霍金在新书中称，上帝并没有创造宇宙，宇宙大爆炸理论是物理定律的必然结果。
In \"The Grand Design,\" co-authored with US physicist Leonard Mlodinow, Hawking says a new series of theories made a creator of the universe redundant（多余的，过剩的） , according to the Times newspaper which published extracts on Thursday.
\"Because there is a law such as gravity, the universe can and will create itself from nothing.Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist,\" Hawking writes.
\"It is not neceary to invoke（祈求） God to light the blue touch paper and set the universe going.\"
Hawking, 68, who won global recognition with his 1988 book \"A Brief History of Time,\" an account of the origins of the universe, is renowned for his work on black holes, cosmology（宇宙论） and quantum gravity.
Since 1974, the scientist has worked on marrying the two cornerstones of modern physics -- Albert Einstein\'s General Theory of Relativity, which concerns gravity and large-scale phenomena, and quantum theory, which covers subatomic particles（亚原子微粒） .
His latest comments suggest he has broken away from previous views he has expreed on religion.Previously, he wrote that the laws of physics meant it was simply not neceary to believe that God had intervened in the Big Bang.He wrote in A Brief History ...\"If we discover a complete theory, it would be the ultimate triumph of human reason -- for then we should know the mind of God.\"
Hawking, who is only able to speak through a computer-generated voice synthesizer, has a neuro muscular dystrophy（肌肉萎缩症） that has progreed over the years and left him almost completely paralyzed.
He began suffering the disease in his early 20s but went on to establish himself as one of the world\'s leading scientific authorities, and has also made guest appearances in \"Star Trek\" and the cartoons \"Futurama\" and \"The Simpsons.\" “The Grand Design” is due to go on sale next week.
CAPITAL CULTURE: All the presidents\' best-sellers By DOUGLASS K.DANIEL, Aociated Pre Writer Dougla K.Daniel, Aociated Pre Writer – Tue Sep 7, 12:06 pm ET
WASHINGTON – Already in distinctive company as an American president, George W.Bush seeks to join an even more select group: president and top-selling author.
Since The New York Times began its weekly lists of best-sellers in 1942, only six of the 13 men who have served as the nation\'s chief executive have placed a book at the top spot for nonfiction, none while president.
Two of them, Dwight D.Eisenhower and Barack Obama, did it before they were in the Oval Office.Two others, Jimmy Carter and Bill Clinton, did it after they had returned to private life.John F.Kennedy and Ronald Reagan also reached the height of the best-seller list, albeit posthumously.
Not that the other chief executives didn\'t try.Richard M.Nixon wrote 12 books, nearly all of them after he resigned as president.Harry Truman, Lyndon B.Johnson, Gerald R.Ford and George H.W.Bush also turned author but never enjoyed the satisfaction that comes with a top seller.
George W.Bush\'s book, \"Decision Points,\" is set for release this fall by Crown Publishers.It\'s not an autobiography, Bush says, but an analysis of key moments in his life, from quitting drinking to invading Iraq.
Presidential memoirs bring prestige to their publishers and can draw healthy sales.Yet they are not known for their stylistic prose or for being particularly introspective.Self-serving to a fault, they tend to play down their authors\' flaws and failings.
\"Memoirs are a running start on legacy spinning,\" says Douglas Brinkley, a Rice University profeor of history and author of the best-seller \"The Wilderne Warrior: Theodore Roosevelt and the Crusade for America.\"
Rather than providing unique insights, memoirs can seem more aimed at protecting a reputation and bolstering fundraising for the presidential library, Brinkley says.\"When you start having memoir ginned out by committee,\" he says, \"it loses its intimacy and authenticity.\"
Franklin D.Roosevelt was president when the Times best-seller list debuted.He and Kennedy died in office, turns of fate that robbed them of an opportunity to look back at their lives and administrations.
Kennedy, though, had already won readers and a Pulitzer Prize for \"Profiles in Courage,\" a 1956 collection of biographical sketches about politicians who took principled if unpopular stands.The book was a best-seller, and its paperback version had sold more
than 2.8 million copies before Kennedy was shot on Nov.22, 1963.Yet the book didn\'t lead all others until a month after his aaination.A commemorative edition was No.1 for 12 weeks.
Four years before he was elected in 1952, Eisenhower wrote a critically acclaimed wartime memoir, \"Crusade in Europe.\" The book brought financial security to the career soldier.He sold all rights for $635,000, more than $6 million in today\'s dollars, to take advantage of a loophole to pay taxes at a 25 percent rate instead of 75 percent.The book was No.1 for 11 weeks and eventually sold well over 1 million copies.
Upon publication in 1990 of his ghostwritten memoir, \"An American Life,\" Reagan joked, \"One of these days I\'m going to read it myself.\" It rose only as far as No.5.\"The Reagan Diaries,\" edited by Brinkley, led the list for two weeks in 2007, three years after the former president\'s death.
Carter wrote a wide-ranging biography and later published a detailed account of his childhood, \"An Hour Before Daylight: Memories of a Rural Boyhood.\" It was atop the best-seller list for five weeks in 2001 and one of three finalists for the Pulitzer Prize for biography or autobiography.
A 2005 book by Carter, \"Our Endangered Values: America\'s Moral Crisis,\" was the best of sellers for four weeks.
The story of a poor Arkansas boy who grew up to be president â ” one dogged by titillating sex scandals â ” trumped a meditation on the joys of doing for others.
Clinton\'s maive autobiography, \"My Life,\" appeared in 2004 as a nearly 1,000-page hardcover — it spent six weeks at No.1 — and later as a two-volume paperback.He scored another top seller, for one week in 2007, with \"Giving: How Each of Us Can Change the World.\" It clocked in at a comparatively petite 240 pages.
Like Eisenhower and Kennedy, Obama wrote his best-seller, \"The Audacity of Hope,\" before he was president.Appearing in 2006, two years before his election, it was No.1 for 16 weeks.
Obama will surely join George W.Bush and other ex-presidents in writing about his administration.(Crown has signed Obama for a post-administration nonfiction book.) He\'s already revisited his childhood, writing \"Dreams from My Father: A Story of Race and Inheritance,\" published in 1995, well before he held any elective office.
That memoir garnered scant notice until Obama became noticed himself.Reprinted in 2007, \"Dreams from My Father\" has since joined \"The Audacity of Hope\" as a best-seller.Together, Obama\'s two books account for 6.6 million copies in print.
