许多人担心计算卡路里，但可能无法理解卡路里的含量或者他们真正需要多少卡路里.
卡路里计数：数字减肥的秘诀
Jul.23.201505:19
什么是卡路里?
基本上卡路里是一种能量单位;它测量食物为身体提供多少能量.
以下是帮助消除卡路里混淆的几点：
一磅多少卡路里?
人们一直认为每磅有3500卡路里的热量，因此，如果你每天减少500卡路里的热量，或者每天锻炼和消耗500卡路里的热量（或两者的任何组合），那么你一周会减掉一磅.
然而，这不是一门精确的科学。在减肥方面，有许多不同的变量需要考虑，包括一个人的新陈代谢.
所有卡路里都不一样
例如，一克碳水化合物含有4卡路里，而一克蛋白质则相同。一克脂肪提供9卡路里。碳水化合物通常消化最快，然后蛋白质和脂肪消化更慢。因为这些食物组中的每一个都会影响新陈代谢，这有助于支持所有卡路里都不相同.
最好不要只看你摄入的卡路里数量，而是关注你消耗的卡路里。三者之间的平衡是最佳的.
标签卡路里计数是指导，而不是福音
标签上的卡路里计数允许有20％的摆动。重要的是要记住，营养成分小组的每日百分比值基于2,000卡路里的饮食.
这个数量比我们许多人需要的卡路里更多（那些试图减肥的人）而不是其他人（年轻运动员）.
同样重要的是要指出食品标签上列出的卡路里表明一份特定食品中含有多少卡路里。如果您正在观察体重，则需要注意实际吃的份量，将包装上的数字乘以您消耗的份数.

Counting calories can be a daunting task for many people, especially when they do not understand the content of calories or how many calories they actually need. It is important to note that calories are a unit of energy that measures how much energy food provides to the body. While it is commonly believed that reducing 500 calories per day or burning 500 calories per day through exercise can lead to losing one pound per week, this is not an exact science. There are many variables to consider when it comes to weight loss, including an individuals metabolism. Additionally, not all calories are created equal, as different types of food affect metabolism differently. Therefore, it is best to focus on balancing the calories consumed and burned rather than just counting the number of calories consumed. Food labels can be a helpful guide, but it is important to remember that the calorie count on the label allows for a 20% swing and is based on a 2,000 calorie diet, which may not be suitable for everyone. It is also important to pay attention to the actual serving size and multiply the calorie count accordingly.
