One of the most widely accepted, commonly repeated assumptions (假设) in our culture is that if you exercise, you will lose weight. I exercise all the time, but I still have gut fat that hangs over my belt when I sit. Why isn’t all the exercise getting rid of it?
It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study — the Minnesota Heart Survey — found, more of us at least say we exercise regularly.
And yet obesity (肥胖) figures have risen sharply in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?
The popular belief that exercise is essential for weight control is actually fairly new. As recently as the 1960s, doctors routinely advised against too much exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases — those of the heart in particular. They less often develop cancer and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly over-evaluated.
“In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, exercise researcher at Louisiana State University. Many recent studies have found that exercise isn’t as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or, for that matter, from magazines like this one.
The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can make one hungry. That causes us to eat more, which in turn can negate (使无效) the weight-loss benefits we just gained. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder.

Below is some advice on how to prevent colds and flu.

8 Ways to Avoid Colds and Flu 1. Wash your hands and wash them often The US Naval Health Research Center conducted a study of 40,000 volunteers who were ordered to wash their hands five times a day. The volunteers cut their incidence of flu by 45 percent. 2. Wash your hands twice every time you wash them Researchers at Columbia University found one hand washing had little effect, even when using antibacterial soap. So wash twice if you’re serious about preventing colds. 3. Change your toothbrush every three months You think your toothbrush gets your teeth clean — and it does. But once you’ve finished brushing, it can be a breeding ground for germs. Most dentists recommend you change your brush every two or three months. It’s also a good idea to replace it after you’ve had a cold or flu. 4. Sneeze and cough into your arm or tissue (纸巾) Whoever taught us to cover our mouths when we cough or sneeze got it wrong. That just puts the germs right on our hands, where you can spread them to objects — and other people. Instead, put your arm over your mouth and nose when you sneeze or cough if a tissue isn’t handy. It’s pretty rare that you shake someone’s arm, after all. 5. Stop blaming yourself when things go wrong Believe it or not, blaming yourself makes you more likely to catch a cold! Researchers found that even those who had control over their work were more likely to begin sneezing if they lacked confidence or tended to blame themselves when things went wrong. Such attitudes make people more stressed on the job, and stress, as you know, can challenge your immune system. 6. Once a day, sit in a quiet, dim room, close your eyes, and focus on one word Meditate (冥想). It is a proven way to reduce stress. Studies have shown that stress weakens your immune system. In fact, people with high stress levels have up to twice the number of colds as non-stressed people. 7. Get moving Ride a bike, join a dance class, or go for a walk. A study found that older women who did 45 minutes of gentle exercise, five times a week for a year, were up to three times less likely to get a cold than women who took little exercise. The researchers found that the exercisers’ immune system was strongest in the last three months of the study. 8. Leave the windows in your house open a crack You don’t have to keep all of them open, but one or two in the rooms in which you spend the most time. This is particularly important if you live in a newer home, where fresh circulating air has been the victim of energy efficiency. A bit of fresh air will do wonders for chasing out germs. |

Some people would go through anything just to achieve their dream. Kasia Siwosz is proof. For the final year student on the university women’s tennis team, the road to Berkeley, University of California was met with poor advice and misinformation from her home country and two unsuccessful stops along the way that fell short of expectations.
Born in Poland, Siwosz began playing tennis at seven years old and developed the skills that helped her earn a top-50 ranking among the ITF Junior division (国际网球联会青少年赛).. Siwosz wanted to do more with her life than just play tennis, which led her to seek chances that would also allow her to obtain a top education. While most who grow up in the U.S. are naturally accustomed to the American tradition of collegiate (大学的) sports, such a custom is not as familiar in a country like Poland. “There’s no collegiate sports in Poland and no culture of sports and academic (学术的) study there. You can only do one, not both,” Siwosz said.
Her desire to have a quality education led her to America to follow her dream. While Siwosz was talented enough to begin her collegiate tennis career, she could only attend community college because she missed the deadline to apply to four-year schools, mainly due to misinformation provided in her home country of Poland.
When she had earned all her credits and was able to transfer (转学), Siwosz made the decision to attend Baylor in Texas. Her friends from Poland put in a good word for the university, saying that it was a good fit because there were many international players at Baylor. “I thought it would be a good idea, but it really wasn’t what I thought it would be,” Siwosz said. “I wasn’t happy at Baylor. The level of tennis was high, but the academic standards were no match and I just wanted more.”
After one year at Baylor, Siwosz’s luck finally began to change when she made the decision to transfer to Berkeley, which was due in large part to Lee, a former Berkeley student. Lee, who is a keen tennis player himself, met Siwosz four years ago in Texas. “I knew she was unhappy there,” he said. “I saw the opportunity for her to come here.” Siwosz visited Lee in Berkeley. “I ended up loving this place and this school,” Siwosz said. “I came here a lot over the summer, I gave it a shot and I ended up with a Berkeley education and a spot on one of the best college tennis teams in the country.”
