Nobody likes dieting①. But is there any really other choice for those who want to lose weight？ Yes， there is. Look at the data below to see how many calories you can burn if you replace some fat with muscle.
Let’s face it.
You can’t change your genes， your age or your gender②， so there are some parts of the metabolic equation that will stay constant no matter what you do. But with a few changes in your exercise and eating habits， you can boost③ your metabolism by up to 10 percent， according to researcher R.Scott Van Zant， PHD， of Northern Arizona University’s Department of Health， Physical Education， Exercise Science and Nutrition. If that doesn’t seem like much， consider this： if a 150-pound woman changed her exercise habits and converted 10 percent of her body fat to muscle， she would be able to consume 300 extra calories a day without gaining weight. Looked at another way， the right change in your metabolism could mean you can eat three chocolate chip cookies every day， without gaining weight.

学会燃耗脂肪
没有人喜欢节食，但对于想减轻体重的人来说真的没有别的选择了吗？不，有。看看下面的数据，了解一下用肌肉替换脂肪需要燃耗多少卡路里。
让我们面对它。
你不能改变你的基因、你的年龄或你的性别，所以无论你怎么做，新陈代谢规律的某些部分是不变的．据北亚利桑那州大学卫生体育教育运动科学和营养系的研究员斯考·范·让特博士说，只要在你的饮食和锻炼习惯上做一些小改动，你就能使你的新陈代谢率增加10％。如果看上去这并不太多，想一想这个事实：假使一个体重150磅的妇女改变她的运动习惯，使身体10％的脂肪转化为肌肉，那么她就可以每天多摄入300卡路里热量而不增加体重。从另一方面看，适当改变新陈代谢可能意味着你可以每天吃三块巧克力饼而不增加体重。
