cative new study shows that a substantial number of people who take up an exercise regimen wind up heavier afterward than they were at the start, with the weight gain due mostly to extra fat, not muscle. But the study also finds, for the first time, that one simple strategy may improve people s odds of actually dropping pounds with exercise. As we all know, the fundamentals of weight loss should be simple. Burn more calories on any given day than you consume and, over time, you will lose weight. Theoretically, we can achieve that desirable condition by reducing the number of calories that we take in through dieting or by increasing the number of calories that we consume through exercise. But in reality, most people do not achieve or sustain weight loss, no matter what method they try.

A.criticisms

B.skepticism

C.compliments

A New Drug for Losing Weight

Scientists have developed a slimming drug that successfully suppresses appetite and results in a dramatic loss of weight without any apparent ill effects. The drug interferes with appetite control and prevents the build-up of fatty tissue. More importantly， the drug appears to prevent a serious decline metabolic rate——causing tiredness and lethargy——which is typically associated with living on a starvation diet. S a result， mice taking the drug lost 45 percent more weight than mice fed the same amount of food， which compensate for the lack of food by becoming more sluggish.

The scientists， from the Johns Hopkins University in Baltimore， said that C75 is likely to produce a similar effect on humans because appetite control in the brain is thought to be based largely on the same chemical pathways as those in mice. "We are not claiming to have found the fabled weight-loss drug. What we have found， using C75， is a major path way in the brain that the body uses naturally in regulating appetite at least in mice，" said Francis Kuhajda， a pathologist and senior team member. "We badly need effective drugs for weight loss. Obesity is a huge problem.

We"re hoping to explore the possibilities of this new pathway，" he said.

Discovering a biochemical. Pathway in the brain that controls appetite raises new prospects for eloping slimming aids. Research on leptin， a hormone produced in fatty tissue for controlling fat deposits， has so far failed to produce the expected slimming drug break-through. The latest study， published in the journal Science， showed that even moderate doses of C75 produced a significant loss of appetite， which returned to normal after a few months.

The scientists believe that C75， which they produced synthetically in the laboratory， binds to an enzyme called fatty acid sythase， which is involved in storing excess food intake as fat.

Inhibiting enzyme causes a build-up of a chemical in the liver which acts as a precursor to fat deposition. This precursor is thought to have an indirect effect on the brain， causing appetite suppression.

Normally， when animals fast， a hormone called neuropeptide Y increases sharply in the appe-tite control centers of the brain， stimulating the desire for food. However， when animals are given C75， levels of this hormone fall， leading to a loss of interest in food. Dr Kuhajda said discovering that C75 has no effect on metabolic rate is one of the most significant findings of the study. "If you try to lose weight by starving， your metabolism slows down after a few days，" he said. "It"s a survival mechanism that sabotages many diets. We see this in fasting mice. Yet metabolic rate in the C75-treated mice doesn"t slow at all. "Further animals studies will be needed before C75 could be tested on humans.

Living on a starvation diet may result in __________. 查看材料

A.a dramatic loss of weight without any ill effects

听力原文： Just because you're on a diet doesn't mean you can't snack. In fact, eating between meals is important for weight loss; the diet we're putting you on emphasizes numerous small meals over fewer large meals. Snacking will give you the energy you need and help satisfy your hunger. But choose your snacks wisely. Munch on fruits or vegetables when you get the urge. They provide vitamins and are good for your digestion. Remember: "eat little and eat often" works as a philosophy that will lead you back to health.

What is the speaker mainly talking about？

A．Explaining how important vitamins are

B．Describing procedures for losing weight

C．Instructing how to choose snacks

D．Informing of snacking for health
