A
diet based on healthy carbohydrates-rather than a low-fat or low-carbohydrate diet-offers the best chance of keeping weight off without bringing unwanted side effects, a study published Tuesday in the Journal of the American Medical Association suggests.
《美国医学学会杂志》（Journal of the American Medical Association）6月26日刊登的一项研究报告指出，以健康碳水化合物为主的饮食──而非低脂或低碳水化合物饮食──能达到最佳的减肥效果，并且不会带来副作用。
Study participants following a low-glycemic-index diet, which is similar to a Mediterranean diet and focuses on fish, fruit, vegetables, nuts and whole grains, also saw improved cholesterol levels and other important markers that lower the risks of developing heart disease and diabetes. Such a diet might include minimally processed oatmeal, almonds, brown rice, beans and healthy fats like olive oil, among other foods.
研究发现，遵循低血糖指数饮食方案的研究对象的胆固醇水平及其他几项降低罹患心脏病和糖尿病风险的重要指标也有所改善。低血糖指数饮食与地中海式饮食相似，主要食用鱼类、水果、蔬菜、坚果和全谷物食品。该种饮食也可包括轻微加工过的燕麦片、杏仁、糙米、豆类和以橄榄油为代表的健康油脂等食物。
The study was led by researchers at the New Balance Foundation Obesity Prevention Center at Boston Children's Hospital and funded by the National Institutes of Health and the New Balance Foundation, which is affiliated with the athletic-shoe maker. It was designed to assess how each of three common diets affects the ability to keep weight off. Participants had all of their food prepared for them, and their food intake was monitored. They ate many meals at the hospital, picking up others to eat at home.
这项研究由波士顿儿童医院（Boston Children's Hospital）新百伦基金肥胖预防中心（New BalanceFoundation Obesity Prevention Center）的研究人员主导，由美国国立卫生研究院（National Institutes of Health）和运动鞋制造商新百伦旗下的新百伦基金会（New Balance Foundation）提供资助。研究旨在评估三种日常饮食方案对减肥效果的影响。研究对象只吃研究人员为其准备的食物，他们的进食过程也受到监控。他们有时在医院用餐，有时将食物带回家吃。
David Ludwig, one of the study's authors and the director of the center, explained that most people struggle to keep weight off. Previous studies have shown that weight loss reduces the body's daily energy expenditure-or how many calories the body burns through activity and just by resting-making it easy to regain weight. Dr. Ludwig's study was designed to look at the
impact of the three diets on measures of energy expenditure, in addition to assessing hormones, fat levels in the blood and other health markers.
研究报告作者之一、肥胖预防中心主任大卫•路德维希（David Ludwig）解释说，大多数人都在费尽心机减肥。以往的研究已经证明，体重减轻会降低身体每日的能量支出──即身体通过活动或只是静止不动燃烧掉的卡路里──这样使得体重容易反弹。路德维希的研究旨在观察三种饮食方案对热量消耗量的影响，同时评估血液中的激素和脂肪水平以及其他的健康指标。
The study's 21 participants, 18 to 40 years old, initially lost 10% to 15% of their body weightduring a three-month diet that contained about 45% of total calories from carbohydrates, 30% from fat and 25% from protein.
21名研究对象年龄在18到40岁之间。他们在最初的三个月里减掉了10%-15%的体重，这三个月里他们遵循的饮食方案中45%的热量来自碳水化合物，30%来自脂肪，还有25%来自蛋白质。
