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.

From the passage we learn that ____.

A. some Americans join a health club but never go there  

B. the number of overweight people has doubled since 1993

C. more than 45 million Americans now go to the gym regularly

D. Americans waste too much money each year on sports

B. is not properly advertised as an effective way to lose weight

C. was first recognized as an effective way to lose weight in the 1960s

According to the writer, people might gain weight because ____.

A. they have the habit of going to the gym regularly

B. they eat the same food when they do not exercise

C. they exercise less than required by doctors

D. they eat more after they exercise

What may be the best title for this passage?

A. Overweight Is Not Good for Your Health

B. Exercise Won’t Make You Thin

For a while, my neighborhood was taken over by an army of joggers. They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. "Come on!" My friend Alex encouraged me to join him as he jogged by my house every evening. "You'll feel great."
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army, I'm not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet will be a real pounding ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say, "I love being out there with just my thoughts." Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn't just the first week: it was practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm enjoying it at the same time. I could never say the same for jogging, and I've found a lot of better ways to stay in shape.
