TDEE 计算器
计算您的每日总能量消耗和每日卡路里需求。
TDEE 计算器估算您的每日总能量消耗——考虑到您的基础代谢率 (BMR) 和体力活动水平，您的身体每天燃烧的总卡路里数。TDEE 是任何基于卡路里的饮食或健身计划的基础：吃少于 TDEE 会产生减重赤字，吃超过它会增重。
输入您的年龄、身高、体重、生理性别，并选择从久坐到非常活跃的活动水平。该工具使用 Mifflin-St Jeor 方程（对大多数成年人最有效的公式）计算 BMR，并乘以活动系数得出 TDEE。
TDEE 是估算值，不是保证——个人代谢有所不同。将其作为起点，追踪 2-3 周内的实际体重变化，并相应调整卡路里摄入量。一个常见方法是从 TDEE 中减去 500 卡路里，以实现每周约 0.5 千克的安全减重。
