Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates (碳水化合物)一all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a high一protein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet.
Wycherley from the University of South Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.
It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”
【小题1】According to Wycherley’s analysis, dieters should take in more .A．fatB．carbohydratesC．proteinD．calories【小题2】What can we learn from the studies?A．It bums more calories to deal with carbohydrates.B．Protein helps keep muscle mass which bums calories.C．Vegetables contain more protein than animals.D．No more calories are burned while the body is resting.【小题3】What is Levine’s attitude towards the conclusion of the studies?A．Doubtful.B．Supportive.C．Curious.D．Agreeable.C

(答案→)C 解析：文章讲述了咖啡这种饮品的发现，传播的经过。同时也讲述了咖啡这种饮品的功能。【小题1】C细节理解题。Wycherley from the University of South Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates.句意为：相比较碳水化合物来说，在处理蛋白质的过程中，身体会消耗更多的能量和卡路里。由此可知根据他的分析应该吸收更多的蛋白质。【小题2】B细节理解题。由第二自然段的第一句话可知，处理蛋白质的时候比处理碳水化合时烧掉的卡路里多，故A是错误的。第二自然段的最后一句话，人们从肉类和蔬菜类中获取蛋白质，但并未说明蔬菜含的蛋白质多，故C是错误的。Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass.句意为：另外一种解释是吃蛋白质有助于保存肌肉块，而肌肉块能消耗更多的卡路里，甚至是休息的时候。由此可知D是错误的。【小题3】A细节理解题。It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion.句意为：蛋白质对碳水化合物的高比率能帮助人们减肥的原因并不是十分清晰，是否有足够的证据得出这个结论也没有涉及到，所以由此可知，应该是持怀疑的态度。

哦，回答的不错
