Dieters are often advised to stop drinking alcohol to avoid the extra calories lurking in a glass of wine or a favorite cocktail. But new research suggests that women who regularly consume moderate(适度的) amounts of alcohol are
less likely to gain weight than nondrinkers and are at lower risk for obesity (fatness).
The findings, reported this week in the Archives of Internal Medicine, are based on a study of 19,220 United States women aged 30 to 40 who fall into the “normal weight” based on their body mass index. Researchers at Brigham and Women’s Hospital in Boston tracked the women’s drinking habits over 13 years. About 60 percent of the women were light or regular drinkers, while about 40 percent reported drinking no alcohol.
Over the course of the study, 41 percent of the women became overweight. Although alcohol is packed with calories, the nondrinkers in the study actually gained more weight over time: nine pounds, on average, compared with an average gain of about three pounds among regular moderate drinkers. The risk of becoming overweight was almost 30 percent lower for women who consumed one or two alcohol drinks a day, compared with nondrinkers.
The findings are certain to be confusing for women who continue to receive conflicting messages about the health benefits and risks of alcohol. Although moderate drinking is associated with better heart health, regular drinking also increases breast cancer risk.
The trend toward les
s weight gain among drinkers doesn’t appear to hold true for men. A 2003 study of Briti
sh men showed that regular drinkers gained more weight than nondrinkers. Studies suggest that drinking alcohol has different effects on eating habits among men and women. Men typically add alcohol to their daily caloric intake, whereas women are more likely to substitute（替代）alcohol for food. In addition, there may be differences in how men and women metabolize（代谢）alcohol. Metabolic studies show that after men drink alcohol, they experience little if any metabolic change. But alcohol appears to slightly speed up a woman’s metabolism.
The findings don’t mean women should rush to drink alcohol to lose weight. Other research shows that once a person is already overweight, her alcohol metabolism is more efficient, and so an overweight woman may gain more weight from alcohol than a lean(瘦的) woman. The data do, however, suggest that for many women facing weight problems, the extra calories are probably not coming from alcoholic drinks.

Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.
Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.
Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陈代谢的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.
Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.
Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”

The Red Panda isn’t much bigger than an average size house cat. At first you may think it’s a bear because of its name. They’re actually a member of the raccoon(浣熊) family which you can tell if you look at their appearance. The Red Panda has a long bushy tail that is useful in two ways. It helps them stay balanced when they are high up in the trees and it keeps them warm in cold weather. Their fur is thick and reddish brown, which may be why they’re known as the fire fox.
The Red Panda can be found in forested mountains. They’re originally from the forested mountain in the Himalayas in India, Nepal and Southern China. Bamboo is the most important part of their diet. They only eat the young leaves and shoots (嫩芽) of a bamboo plant. Red Pandas have a very low metabolic(新陈代谢的) rate in order to deal with their low energy diet and cool environmental temperatures.
They’re very shy and gentle and don’t hang around the wild too much during the day. If they feel endangered, they’ll stand on their back legs and make a hissing(嘶嘶) sound. Red Pandas are good climbers and spend most of their time living mainly in trees. Their claws are very strong and help them hold onto the branches. They sleep in an unusual way by curling up tightly and wrapping their tails around their heads while sitting on a branch. Sometimes they’ll sleep with their head beneath their chest and behind their back feet. This is the same position as an American raccoon sleeps.
【小题1】You can tell that the Red Panda is a member of the raccoon family from ____.
| A．its name | B．its appearance | C．its diet | D．its living place |
| A．The Red Panda can only be found in India, Nepal and Southern China. |
| B．The Red Panda’s tail can help it stay balanced when it is high up in the trees. |
| C．The Red Panda eats the whole of the bamboo. |
| D．The Red Panda has high metabolic rate when the temperature is low. |
| A．They will hang around the wild during the day. |
| B．They will climb into the trees. |
| C．They will wrap their tails around their heads. |
| D．They will stand on their back legs and make a hissing sound. |
| A．tail | B．fur | C．back legs | D．claws |
