Exercise burns calories, no one doubts that, and so it should, in theory, produce

17、 weight loss, a fact that has prompted countless people to undertake exercise programs to shed pounds. Without significantly changing their diets, few succeed. “Anecdotally, all of us have been cornered by people claiming to have spent hours each week walking. running, stair-stepping, etc., and are

18、displeased with the results on the scale or in the mirror, “wrote Barry Braun. an associate professor of kinesiology at the University of Massachusetts at Amherst.But a growing body of science suggests that exercise does have an important role in weight loss. That role, however, is different from wh

19、at many people expect and probably wish. The newest science suggests that exercise alone will not make you thin, but it may determine whether you stay thin, if you can achieve that state. Until recently, the bodily mechanisms involved were mysterious. But scientists are slowly teasing out exercises

20、impact on metabolism, appetite and body composition , though the consequences of exercise can vary. Womens bodies, for instance, seem to react differently than mens bodies to the metabolic effects of exercise. None of which is a reason to abandon exercise as a weight-loss tool. You just have to unde

21、rstand what exercise can and cannot do.“In general, exercise by itself is pretty useless for weight loss, “says Eric Ravussin, an expert on weight loss. Its especially useless because people often end up consuming more calories when they exercise. The mathematics of weight loss is, in fact, quite si

22、mple, involving only subtraction. “Take in fewer calories than you burn, put yourself in negative energy balance, lose weight, “says Braun, who has been studying exercise and weight loss for years. The deficit in calories can result from cutting back your food intake or from increasing your energy o

23、utput the amount of exercise you complete or both. When researchers affiliated with the Pennington center had volunteers reduce their energy balance for a study by either cutting their calorie intakes by 25 percent or increasing their daily exercise by 12.5 percent and cutting their calories by 12.5

24、 percent, everyone involved lost weight. They all lost about the same amount of weight too about a pound a week. But in the exercising group, the dose of exercise required was nearly an hour a day of moderate-intensity activity. What the federal government currently recommends for weight loss is “a

25、lot more than what many people would be able or willing to do,“ Ravussin says.At the same time, as many people have found after starting a new exercise regimen, working out can have a significant effect on appetite. The mechanisms that control appetite and energy balance in the human body are elegan

26、tly calibrated. “The body aims for homeostasis, “ Braun says. It likes to remain at whatever weight its used to. So even small changes in energy balance can produce rapid changes in certain hormones associated with appetite, particularly acylated ghrelin, which is known to increase the desire for fo

27、od, as well as insulin and leptin, hormones that affect how the body burns fuel.The effects of exercise on the appetite and energy systems, however, are by no means consistent. In one study presented last year at the annual conference of the American College of Sports Medicine, when healthy young me

28、n ran for an hour and a half on a treadmill at a fairly high intensity, their blood concentrations of acylated ghrelin fell, and food held little appeal for the rest of that day. Exercise blunted their appetites. A study that Braun oversaw had a slightly different outcome. In it, 18 overweight men a

29、nd women walked on treadmills in multiple sessions while either eating enough that day to replace the calories burned during exercise or not. Afterward, the men displayed little or no changes in their energy-regulating hormones or their appetites, much as in the other study. But the women uniformly

30、had increased blood concentrations of acylated ghrelin and decreased concentrations of insulin after the sessions in which they had eaten less than they had burned. Their bodies were directing them to replace the lost calories. In physiological terms, the results “are consistent with the paradigm th

31、at mechanisms to maintain body fat are more effective in women, “Braun and his colleagues wrote. In practical terms, the results are scientific proof that life is unfair. Female bodies, inspired almost certainly“ by a biological need to maintain energy stores for reproduction, “Braun says, fight har

37、4.00)Researchers investigating brain size and mental ability say their work offers evidence that education protects the mind from the brains physical deterioration.It is known that the brain shrinks as the body ages, but the effects on mental ability are different from person to person. Interestingl

38、y, in a study of elderly men and women, those who had more education actually had more brain shrinkage.“That may seem like bad news,“ said study author Dr. Edward Coffey, a professor of psychiatry and of neurology at Henry Ford Health System in Detroit. However, he explained, the finding suggests th

39、at education allows people to with stand more brain-tissue loss before their mental functioning begins to break down.The study, published in the July issue of Neurology, is the first to provide biological evidence to support a concept called the “reserve“ hypothesis, according to the researchers. In

40、 recent years, investigators have developed the idea that people who are more educated have greater cognitive reserves to draw upon as the brain tissue to spare.Examining brain scans of 320 healthy men and women ages 66 to 90, researchers found that for each year of education the subjects had, there

41、 was greater shrinkage of the outer layer of the brain known as the cortex. Yet on tests of cognition and memory, all participants scored in the range indicating normal.“Everyone has some degree of brain shrinkage,“ Coffey said.“ People lose (on average) 2.5 percent decade starting at adulthood.“The

42、re is, however, a “remarkable range“ of shrinkage among people who show no signs of mental decline, Coffey noted. Overall health, he said, accounts for some differences in brain size. Alcohol or drug use, as well as medical conditions such as diabetes and high blood pressure, contribute to brain-tis

43、sue loss throughout adulthood.In the absence of such medical conditions, Coffey said, education level helps explain the range of brain shrinkage exhibited among the mentally-fit elderly. The more-educated can withstand greater loss.Coffey and colleagues gauged shrinkage of the cortex by measuring th

44、e cerebrospinal fluid surrounding the brain. The greater the amount of fluid, the greater the cortical shrinkage. Controlling for the health factors that contribute to brain injury, the researchers found that education was related to the severity of brain shrinkage. For each year of education from f

45、irst grade on, subjects had an average of 1.77 milliliters more cerebrospinal fluid around the brain.For example, Coffeys team reported, among subjects of the same sex and similar age and skull size, those with 16 years of education had 8 percent to 10 percent more cerebrospinal fluid compared with

46、those who had four years of schooling.Of course, achieving a particular education level is not the definitive measure of someones mental capacity. And, said Coffey, education can be “a proxy for many things“. More-educated people, he noted, are often less likely to have habits, such as smoking, that

47、 harm overall health. But Coffey said that his teams findings suggest that like the body, the brain benefits from exercise.“ The question is whether by continuing to exercise the brain we can forestall the effects of (brain shrinkage),“ he said. “My hunch is that we can.“According to Coffey, people

48、should strive throughout life to keep their brains alert by exposing themselves to new experiences. Travelling is one way to stimulate the brain, he said; a less adventuresome way is to do crossword puzzles.“A hot topic down the road,“ Coffey said, “will be whether education even late in life has a protective effect against
