A flood of food comes at us this time of year. So the American Chemical Society has produced a YouTube video with info to help you survive the sweet and savory onslaught.
每年这个时候都会有大量食物出现在我们面前 。于是美国化学协会制作了一个资讯视频，来帮助人们远离甜食和美味的冲击 。
The video from ChemMatters called "The Science Behind Calories and Nutrition Facts Labels," notes that: "A lot of us should pay more attention to nutritional values. For example, you might love having a caramel iced coffee every morning. But if you look at the nutritional info, a large caramel iced coffee from a leading fast food chain has 680 calories." That's almost half the total daily recommended calories for an overweight adult trying to lose weight.
And metabolism is king. "A person's basal metabolic rate, the rate at which a person's body uses energy while at rest, is responsible for up to 70 percent of the calories used by our bodies." And the good news? "People can change their basal metabolic rate by exercising…also people with more muscle and less fat generally have a higher basal metabolic rate." So keep moving. Preferably away from the desserts.
新陈代谢才是最重要的 。“一个人的基础代谢率，即一个人在休息时利用能量的速度，负责向我们的身体提供高达70%的热量 。”好消息是？“人们可以通过锻炼调整基础代谢率...并且总体上肌肉多和脂肪少的人基础代谢率更高 。”所以要保持运动，尽量远离甜点 。
