Combining regular exercise with cutting calories would achieve better health outcomes, according to a new study.

"It's better to lose weight with a combination of caloric reduction and exercise rather than caloric reduction alone," said study author Enette Larson-Meyer, an assistant professor of family and consumer science at the University of Wyoming.

Combining the two results in better health outcomes -- such as lower blood pressure and cholesterol levels -- than simply cutting calories alone, Larson-Meyer and his colleagues found in the study appearing in the January issue of the journal Medicine & Science in Sports & Exercise.

For the six-month study, the researchers assigned 36 overweight men and women, average age 39, to one of three groups. One group cut calories by 25 percent. The second cut calories by about 12.5 percent and exercised enough to increase energy output by 12.5 percent. A control group simply stayed on a weight-maintenance diet.

At the study's end, both the caloric-restriction group and the caloric-restriction plus exercise group lost about 10 percent of their body weight. The average weight at the study start was about178 pounds, so the loss at the end was about 17 pounds on average.

The exercise prescription varied according to body weight at the start, but typically men walked for 50 minutes at a brisk pace five days a week, and women, 45 minutes five times a week, Larson-Meyer said. They could choose their preferred activity and intensity, however.

At the end, those who included exercise had better health outcomes, according to the study.

"The big improvement was related to blood pressure," Larson-Meyer said. The exercising and dieting group had greater blood pressure improvements, and improvement in cholesterol and insulin sensitivity, too, she said.

"It's not surprising at all," Larson-Meyer added. "They definitely work together."

Working with a professional to decide on calorie restriction and workout routine is best, especially for obese people with orthopedic problems, she noted.

新的一项研究发现把经常运动和减少卡路里摄入结合起来可以得到更好的健康结果。

研究报告作者，怀俄明大学家庭与消费者科学助理教授Enette Larson-Meyer指出较好的减肥方法是把坚持运动和减少卡路里的摄入结合起来，而不是仅仅减少卡路里的摄入。

与仅仅减少卡路里摄入相比，这两者的结合可以得到更好的健康结果，其中包括使血压和胆固醇降低。一月份的《体育医学与健康》杂志刊登了Enette Larson-Meye和他同事们的这一发现。

在为期6个月的研究中，研究人员将36个平均年龄为39岁的超重男女分成了3组。一组减少了25%的卡路里摄入；第二组在减少大约12.5%卡路里的摄入的同时，还加上足够的运动以增加12.5%的能量消耗；最后的一组只是简单地继续维持体重的饮食。

研究结束时，限制卡路里摄入的这组和限制卡路里摄入再加上运动的那组都减少了大约10%的体重。研究开始时他们的平均体重是178磅，平均减少的体重约为17磅。

Larson-Meye指出一开始运动方案根据每个人的体重而有所不同，但通常是男子每天轻松步行50分钟，每星期运动5天；女子则是每天45分钟，每星期运动5次。他们也可以选择自己喜欢的运动及其强度。

最后根据这项研究，发现那些参加运动的人得到了更好的健康结果。

Larson-Meyer指出最大的改善是在血压方面。运动加上节食这组成员的血压得到了非常大的的改善，同时得到改善的还有胆固醇和胰岛素敏感性。

他（全文不统一，前文中用的是his）还指出，最好是与专业人员一起来制定限制卡路里摄入和日常运动的方案，对畸形的超重者来说尤其应该如此。
