(40 points)Text 1Your New Years plan to move more is one of the toughest to stick to, and a group of scientists working with obese(过度肥胖的) mice think theyre starting to understand wh
10、yRather than our sedentary(久坐的) lives causing weight gain, says Alexxai Kraviz, the National Institutes of Health neuroscientist who led the study, changes in brain chemistry after we start gaining weight affect our capacity to move.“Obses mice can move just fine,” says Kravitz, who published the wo
11、rk with his team in Cell Metabolism “They just dont.”What Kravitzs team found is that the activity of a particular dopamine(多巴胺) receptor linked to movement goes down as mice gain weight on a high-fat diet. So the nice slow down and they move less. And when the researchers restored the activity of t
12、hat dopamine receptorDR2the mice started moving more, even though they were still obese. The team also saw that lean mice missing the DR2 receptor acted like obese mice. This is the target, says Kravitzrestoring that dopamine receptor function. “Maybe 20 or 30 years down the road, we could do that i

Both sets of mice gained weight at the same rate.Kravitz says this is important because mice lacking DR2 move less from the get-go, whereas a normal mouse takes a little ti

The ability to exercise seems to be disconnected from weight gain, he says.“Exercise is a healthy thing to do, but its impact on weight loss has been exaggerated,” he says. “We have to be realistic about the size of the effect of ex
15、ercise on weight, as opposed to health benefits.”Still, before you abandon your New Years exercise plan, keep in mind that this study was done using a high-fat diet, and not the normal calorie restriction that people maintain when they diet.Thats a big drawback to the work, says Vicki Vieira-Potter, a University of Missouri physiologist not involved in the study.“They feed the mice with high-fat diet, it damages the receptor, and that decreases activity. Those who plan to lost weight should r
