Who uses the 卡路里计算器?

  • 开始减肥之旅、需要基于科学的卡路里目标的人。
  • 计算训练和比赛阶段燃料需求的运动员。
  • 快速计算客户能量需求的营养师和饮食学家。

How the 卡路里计算器 works

1

输入你的年龄、性别、身高和当前体重。

2

可选择输入目标体重,查看达到目标的预计时间表。

3

从久坐到超级活跃中选择你的活动水平(这是计算中最大的变量)。

4

计算会随着你的输入自动更新,显示减重(-500卡路里/天)、轻度减重(-250)、维持体重和增重(+500卡路里/天)的卡路里目标。

Tips & tricks

  • 只使用Mifflin-St Jeor公式——没有Harris-Benedict或其他公式选项,尽管在一般营养建议中有时会提到它作为替代方案。
  • 可选的「目标体重」字段不会改变你的卡路里目标——它只会估算在每天500千卡的赤字或盈余下达到该目标需要多少周。
  • 结果会随着你的输入实时重新计算——调整任何字段后无需再次点击计算。

Frequently Asked Questions

我每天应该吃多少卡路里才能减肥?

每天比你的维持水平少摄入500卡路里,每周可减重约0.5公斤。例如,如果你的维持水平是2200卡路里,那么每天吃1700卡路里。在没有医疗监督的情况下,避免女性低于1200卡路里或男性低于1500卡路里。

BMR和TDEE有什么区别?

BMR(基础代谢率)是完全静止时燃烧的卡路里——仅用于维持生命。TDEE(每日总能量消耗)在此基础上加上你的活动水平。你应该按照TDEE进食以维持体重。此计算器中的「维持体重」卡片显示的就是你的TDEE。

这个计算器使用哪种卡路里公式?

Mifflin-St Jeor方程,该公式被认为对大多数人来说最准确:BMR = 10×体重(千克) + 6.25×身高(厘米) − 5×年龄 + 5(男性)或−161(女性)。这是唯一使用的公式——没有其他公式(如Harris-Benedict)可供切换。

卡路里计算器有多准确?

由于个体代谢差异,TDEE估算可能相差10-20%。将结果作为起点,追踪2-3周内实际的体重变化,然后根据需要调整100-200卡路里的摄入量。

输入目标体重会改变我的卡路里目标吗?

不会——四张卡路里卡片(减重/轻度减重/维持/增重)始终基于相对于你TDEE的固定±250/±500卡路里偏移量。目标体重字段只会额外增加一个估计的周数,以在每天500千卡的赤字或盈余下达到该目标;它不会改变卡路里数字本身。

Is my data safe when using the 卡路里计算器?

Completely safe. The 卡路里计算器 processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.

How accurate are the 卡路里计算器 calculations?

The 卡路里计算器 uses clinically validated formulas such as the Mifflin–St Jeor or Harris–Benedict equations where applicable. Results are population-based estimates and can differ from measured values by 10–20% for individuals with atypical body composition. See our <a href="/methodology/">Methodology page</a> for full formula sources and references. Consult a qualified healthcare professional before making medical or dietary decisions.

Which formula does the 卡路里计算器 use?

The 卡路里计算器 uses an established, peer-reviewed formula endorsed by leading health organisations such as the WHO, CDC, or NIH where applicable. The specific formula is chosen for its validated accuracy across diverse adult populations under normal conditions.
