TDEE 计算器 TDEE Calculator
在基础代谢率(BMR)的基础上,结合活动水平(Activity Level / PAL)估算每日总能量消耗(TDEE)。
Estimate your Total Daily Energy Expenditure (TDEE) from BMR and activity level (PAL), and get practical calorie targets.

这是什么?What is TDEE?
TDEE(Total Daily Energy Expenditure)指你一天“总共消耗”的能量,通常包含:基础代谢(BMR)+ 日常活动(NEAT)+ 运动训练(EAT)+ 食物热效应(TEF)。
TDEE is your total daily calorie burn, often including BMR + daily movement (NEAT) + exercise (EAT) + thermic effect of food (TEF). -
工具怎么算?How does this calculator work?
第一步先算 BMR(基础代谢):这是“你躺着不动,一天大概会消耗多少热量”的估计值。
Step 1: Estimate BMR (Basal Metabolic Rate) — how many calories you burn at rest in a day.
第二步用活动系数 PAL 进行放大:TDEE = BMR × PAL。PAL 越高,代表日常走动更多、工作更耗体力、或训练更频繁。
Step 2: Scale it by PAL: TDEE = BMR × PAL. Higher PAL generally means more movement, more physical work, or more training. -
怎么选活动水平?How to pick PAL?
久坐(1.20):办公室久坐 + 每周几乎不运动;Sedentary: desk job, little exercise.
轻度(1.375):每周 1–3 次轻运动/步行较多;Light: 1–3 light sessions/week or more walking.
中度(1.55):每周 3–5 次训练(力量/跑步等);Moderate: 3–5 sessions/week.
高强度(1.725):每周 6–7 次训练或体力工作;Very active: hard training most days or physical job.
极高(1.90):高强度训练 + 高体力工作叠加;Extra active: very hard training + very active job.
小建议:如果你拿不准,先用 “1.375 或 1.55”,观察 2–3 周体重/围度趋势再微调。
Tip: If unsure, start with 1.375 or 1.55, then adjust after 2–3 weeks using weight/measurements. -
“目标热量偏移”怎么用?How to use Calorie Offset?
你可以把 TDEE 当作“维持热量(Maintenance)”。当偏移是 -15%,表示目标热量 = TDEE × (1 – 15%),用于减脂;+10% 则用于增肌增重。
Treat TDEE as maintenance. A -15% offset means target = TDEE × (1 – 15%) for cutting; +10% for bulking.
实践建议:减脂通常从 -10%~-20% 起步更容易坚持;增肌从 +5%~+15% 更稳健,避免脂肪增长过快。
Practical: cutting often starts at -10% to -20%; bulking +5% to +15% is usually more sustainable. -
为什么算出来和手环/体测不一致?Why doesn’t it match my watch/scale?
这是“估算工具”,不是医学测量。BMR 公式是人群平均模型;而手环也常基于心率、步数与算法推断,同样会有偏差。睡眠、压力、温度、恢复状态、激素周期、饮食结构等都会影响真实消耗。
This is an estimation tool, not a medical measurement. BMR formulas are population averages; wearables also estimate with their own algorithms. Sleep, stress, temperature, recovery, hormones, and diet composition can all shift actual expenditure. -
如何把它变成“你的真实 TDEE”?How to make it personal?
用当前估算值作为起点,连续记录 14–21 天:每日摄入(大致即可)+ 体重趋势(看 7 天均值)。
If your 7-day average weight is stable, your intake is close to true TDEE. If you lose/gain, adjust calories accordingly. (这一步比任何公式都更接近现实。)
体重稳定 ⇒ 摄入≈真实 TDEE;体重下降/上升 ⇒ 说明存在赤字/盈余,据此调节热量。
This calibration step is usually more accurate than any equation.
