Drinking water is always good for weight loss, but this concept is related to the idea that if you drink ice water, your body has to burn calories warming it up.
喝水对减肥总是很有帮助，但认为喝冰水有助于减肥的人往往相信这是由于我们的身体要燃烧卡路里来让冰水变暖，从而达到减肥的效果。
Technically correct, but the number of calories you burn are really tiny. It's about 1 calorie per ounce of ice water to warm it up. We would think it would take more calories to heat up the water, but it doesn't.
这在技术上说得通，但是让冰水变暖所消耗的热量少之又少，让一盎司的冰水变暖只能消耗1卡路里。我们也许觉得让冰水变热会消耗更多的热量，其实不然。
So, drink water, but only ice water if you like it. Of course, you also don't cancel out the calories of an iced beverage that has calories because it's cold (like soda or juice), although that would be nice!
所以，喝水可以，但除非你喜欢，否则没有必要喝冰水。当然，冰镇饮料（如汽水或果汁）并不会因为凉爽而不含热量，尽管那是个美妙的想法。
