你每天需要摄入多少卡路里

Whether you notice it or not, most generic nutrition and dietary recommendations are made based on a 2,000 calorie per day diet. Most nutrition labels, for example, will calculate the percentage of your recommended daily intake of any given nutrient on a 2,000 calorie diet (via US News). This number was created in the 1990s based on self-reported surveys of Americans sharing how much they ate in a day. After compiling the data, researchers concluded that 2,000 calories per day was an average number they could work from.

不管你是否注意到，大多数一般的营养和饮食建议都是基于每天2000卡路里的饮食。例如，大多数营养标签都会计算2000卡路里饮食中任何特定营养素的推荐每日摄入量百分比。这个数字是在20世纪90年代建立的，它是基于美国人分享他们一天吃了多少的自我报告调查。在整理数据后，研究人员得出结论，每天摄入2000卡路里是他们工作的平均值。

It's not surprising, then, to find that this number is not right for everyone. The process used to settle on 2,000 calories per day did not take into account an individual's weight, age, fitness level, health conditions, or other factors that can affect how much they should be eating. The number of calories a professional athlete needs will differ from someone who sits at a desk job all day or a teenager who is going through a growth spurt.

因此，发现这个数字并不适合所有人也就不足为奇了。每天摄入2000卡路里的过程没有考虑到个人的体重、年龄、健康水平、健康状况或其他可能影响他们应该摄入多少的因素。一个职业运动员所需要的卡路里数量不同于整天坐在办公桌前的人，也不同于一个正在经历生长高峰期的青少年。

The number of calories you need to eat every day will depend on many factors. Some of these include your age, weight, sex, activity level, health conditions, and fitness goals. The safest and most accurate way to find your ideal calorie goal is to meet with a registered dietician. However, there are some resources available to help you find a rough calculation on your own.

你每天需要摄入多少卡路里取决于许多因素。其中包括你的年龄、体重、性别、活动水平、健康状况和健身目标。找到理想卡路里目标的最安全、最准确的方法是咨询注册营养师。然而，有一些资源可以帮助您自己找到一个粗略的计算。

Mayo Clinic has an online calculator that lets you enter your age, height, weight, sex, and activity level to determine how many calories you need to maintain your current weight. Healthline has a similar calculator. According to Healthline, you will need to reduce your current calorie intake by about 500 calories per day in order to lose one pound of body weight per week. Generally, a woman's ideal caloric intake will range from 1,500 to 2,500 calories per day and a man's ideal intake will range from 2,100 to 3,000 per day. But again, your caloric needs will be unique to you and your lifestyle.

梅奥诊所有一个在线计算器，可以让你输入你的年龄、身高、体重、性别和活动水平，以确定维持当前体重所需的热量。Healthline有一个类似的计算器。根据Healthline介绍，为了每周减掉一磅体重，你需要每天减少500卡路里的热量摄入。一般来说，女性的理想卡路里摄入量为每天1500至2500卡路里，男性的理想摄入量为每天2100至3000卡路里。但是，你的卡路里需求对你和你的生活方式来说都是独一无二的。
