Are fat-free and low-fat foods low in calories?

无脂和低脂的食物是否卡路里含量低？

Not always. Some fat-free and low-fat foods have extra sugars, which push the calorie amount right back up. The following list of foods and their reduced fat varieties will show you that just because a product is fat-free, it doesn't mean that it is "calorie-free." And, calories do count!

并不一定。有些无脂和低脂的食物有额外的糖，会让卡路里再升高。下表中的食物以及它们的低脂品种会告诉你，“无脂”的食物并不意味着“无卡路里”。卡路里算数的！

Always read the Nutrition Facts food label to find out the calorie content. Remember, this is the calorie content for one serving of the food item, so be sure and check the serving size. If you eat more than one serving, you'll be eating more calories than is listed on the food label.

要经常通过阅读食物营养成分标签发现卡路里的含量。记住，这是一份食物的卡路里含量，所以要明确一份食物量的大小。如果你吃的不止一份，那你将摄入比食品标签中列出来更多的卡路里。

If I eat late at night, will these calories automatically turn into body fat?

如果我晚上很晚吃东西，这些卡路里会自动变成身体脂肪吗？

The time of day isn't what affects how your body uses calories. It's the overall number of calories you eat and the calories you burn over the course of 24 hours that affects your weight.

吃东西的时刻并不影响你的身体使用卡路里。影响你的体重的，是你在24小时内摄入的卡路里的总数和你消耗的卡路里数。

I've heard it is more important to worry about carbohydrates than calories. Is this true?

我听说与卡路里相比，碳水化合物更值得担心。是真的吗？

By focusing only on carbohydrates, you can still eat too many calories. Also, if you drastically reduce the variety of foods in your diet, you could end up sacrificing vital nutrients and not be able to sustain the diet over time.

只关注碳水化合物，你仍可以摄入过多的卡路里。同样，如果你彻底把膳食中食物种类减少，可能最终导致你丧失维持生命必须的营养素，这种饮食也无法一直保持。
