Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years. And indeed, cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates（碳水化合物） have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates — which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body —— dietary fat is more easily converted to body fat. Therefore, it’s more likely to stay on buttocks, thighs and bellies.
But cutting fat from your diet doesn’t necessarily mean your body won’t store fat. For example, between nonfat and regular cookies, there’s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight again. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn’t losing weight. Then he showed his food diary to his coach and revealed he’d been eating half a pound of jelly beans a day. “They don’t have any fat,” he explains. But they had enough sugar to keep him from shedding an ounce.
Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt（酵母乳）that contained exactly the same amount of calories. One group’s yogurt label said “high fat”—the other, “low fat.” The “low fat” yogurt group ate significantly more calories later in the day than the other group. “People think they’ve saved fat and can indulge themselves later in the day with no adverse consequences,” says Richard Mattes, a nutrition researcher at Purdue University. “But when they do that, they don’t compensate very precisely, and they often end up overdoing it.”

Eating disorder is ve ry common now. "When I first wrote about this. the problem was pretty much hidden … I didn’t expect it to get as bad as it is." Susie Orbach, an international authority(权威)on eating disorders, said.
Orbach must at times think the anti-diet message of her book “fat is a Feminist Issue(女权主义问题)”has been lost since it was written more than 20 years ago.
Girls, boys, old people --even the famously well-rounded female population of Fiji are falling victims(牺牲品) to fat fear.
"If anything, the situation has got much, much worse. We now have kids as young as eight and women in old people’s homes worried about the way they look." Orbach said.
Even though it has been proved that repeated dieting results in a little more than regaining most of the lost weight, constant dieting has become a way of life for many women. 48 per cent of British women aged 25 to 35 were on some kind of diet and 20 per cent of young women dieted all or most of time. Some of them said they would pop a pill to give them their beautiful shape, even if it meant risking
their health. Worldwide, 70 million people have an eating disorder. Most are women, but men are increasingly affected, too.
More than half the women and two thirds of the men in Britain weigh too much. while in the United States more than one quarter of adults and about one in five children are overweight. The idea that female beauty is a very thin body could be changed, if clothing factories and magazines showed images(形象) of women of all shapes instead of selecting skeletal-like models and stick-thin actress.
But that is easier said than done.
To get the message across, Orbach is also considering talking to pop stars such as Victoria Beckham and Geri Halliwell, both of whom have admitted__________________.

Healthy knees aren"t the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos (细高跟鞋).
"It takes a long time to feel the effects of knee osteoarthritis (骨关节炎) — and once you do, it is too ]ate," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School"s department of physical medicine.
"I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said. "They are better for your feet than stiletto heels, but just as had for your knees."
The idea that high heels are bad for your health isn"t new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained (扭伤) ankles and back problems.
But in 1998,Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage (软骨) surrounding the knee.
The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.
"This study confirms what we all intuitively (直觉地) know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.

Happiness is U-shaped, for we are happier at the start and end of our lives but hit a slump when we are middle-aged, British and US researchers say.
Economists from the University of Warwick, central England, and from Dartmouth College, New Hampshire, looked at data on the mental health of two million people from 80 countries.
In Britain, the probability of depression for men and women peaks at around 44 years of age, Warwick University said in a press release.
In the United States, though, ________________________between men and women. Among women, unhappiness peaked at around the age of 40, whereas among men, it was about 50.
But the U-shape of happiness is constant around the world, and mid-life depression occurs regardless of marital status(婚姻状况), changes in job or income.
The study appears in Social Science & Medicine, published by the Dutch publishing house Elsevier.
"It happens to men and women, to single and married people, to rich and poor, and to those with and without children." said co-author Andrew Oswald.
One possibility may be that people realize they won"t achieve many of their ambitions at middle age. The researchers said.
Another reason could be that after seeing their fellow middle-aged peers begin to die, people begin to value their own remaining years and embrace life once more.
But the good news is that if people make it to aged 70 and are still physically fit, they are on average as happy and mentally healthy as a 20-year old.
"For the average persons in the modern world, the dip in mental health and happiness comes on slowly, not suddenly in a single year," Oswald said. "Only in their fifties do people emerge from this low period.

We Should All Grow Fat and Be Happy
Here’s a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn’t eat this and she mustn’t that. Oh, but of course, she doesn’t want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it’s the surest way to an early grave. They spend a truly memorable evening together and never see each other again.
What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for ‘health cures’. For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don’t think it’s only the middle-aged who go in for these fads either. Many of these bright young things you see are suffering from chronic malnutrition: they are living on nothing but air, water and the goodwill of God.
Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they’re always hungry. You can’t be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood(奇妙的事物) is a complete food, the advertisement says. ‘Just dissolve a teaspoonful in water…’. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they’re always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice!
What’s all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly（saintly<圣洁的>的反义词） people do so to attain a state of misery. It will be a great day when all the dieters in the world abandon their slimming courses; when they hold out their plates and demand second helpings!

CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards.
A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle.
Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat.
"Most people don"t give much thought to the grime that builds up on their PC, but if you don"t clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement.
The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria.
Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards.
But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse.
Almost half -- or 46 per cent -- cleaned their keyboard less than once a month.
To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them.
小题1:The purpose of the passage is .| A．tell us something about the keyboards. | | B．warn people to clean the keyboards often. | | C．tell us how to clean the keyboard | | D．tell us the germs on keyboards |
小题2:What do you think the expression “Think twice before eating those dropped crumbs off your computer keyboard” stands for?| A．Think several times before eating beside your computer | | B．Don’t drop foods onto the computer keyboard. | | C．Don’t eat foods dropped onto the computer keyboard. | | D．Be careful when you are eating by the computer. |
小题3:What are the main causes of a bug-infested keyboard?| A．Dropped crumbs and food encourages the growth of millions of bacteria. | | B．Poor personal hygiene | | C．Much dirt on the computer keyboard. | | D．Dropped crumbs and food and Poor personal hygiene |
小题4:"Which? Computing" is probably a name of . | A．An organization | B．a newspaper | | C．a report | D．a magazine |
