基础代谢率计算器 BMR Calculator

根据性别、年龄、身高和体重,估算静息状态下每天消耗的最低热量(基础代谢率),并结合活动水平估算每日总能量需求。
Estimate your Basal Metabolic Rate (BMR) using sex, age, height and weight, and combine it with your activity level to approximate your daily calorie needs.

1. 输入参数 · Input Parameters
基础代谢率与性别有关,男性与女性使用不同的估算公式。
BMR depends on sex; different equations are used for males and females.
建议输入 10–120 岁之间的整数年龄,年龄越大,基础代谢通常会略有下降。
Use an integer age between 10 and 120. BMR generally decreases slightly as age increases.
输入身高的单位为厘米,例如 170 代表 1.70 米。
Height should be in centimeters, for example 170 means 1.70 meters.
使用当前实际体重(kg)。如需使用目标体重评估,也可以输入目标体重进行模拟。
Enter your current body weight in kilograms. You may also enter a target weight if you want to simulate.
活动水平越高,每天总能量消耗越多。活动系数会乘在 BMR 上得到 TDEE(每日总能量消耗)。
Higher activity levels mean higher daily calorie needs. The activity factor multiplies your BMR to estimate TDEE (Total Daily Energy Expenditure).
3. 计算公式与使用提示 · Formula & Usage Notes
  • 1)基础代谢率(BMR)的含义 · What is BMR:
    基础代谢率指在清醒、完全静息、环境温度适宜且未进食的状态下,维持心跳、呼吸、体温、器官运转等生命活动所需的最低能量。
    BMR is the minimum amount of energy your body needs at rest to keep vital functions running, such as heartbeat, breathing, body temperature and organ functions.
  • 2)本工具采用的公式 · Formula used in this tool:
    使用常用的 Mifflin-St Jeor 公式(以 kg、cm、岁为单位)进行估算:
    This tool uses the widely accepted Mifflin-St Jeor equation (in kg, cm, years):
    男性 Male:BMR = 10 × 体重(kg) + 6.25 × 身高(cm) − 5 × 年龄 + 5
    女性 Female:BMR = 10 × 体重(kg) + 6.25 × 身高(cm) − 5 × 年龄 − 161
  • 3)每日总能量消耗(TDEE) · Total Daily Energy (TDEE):
    在 BMR 的基础上,根据日常活动水平乘以活动系数:TDEE = BMR × 活动系数。活动越频繁或运动强度越大,所需热量越高。
    TDEE is estimated by multiplying BMR with an activity factor: TDEE = BMR × activity factor. More movement and higher training intensity mean higher daily calorie needs.
  • 4)如何利用结果做体重管理 · How to use this for weight management:
    一般来说:
    · 若摄入热量 ≈ TDEE,体重大致维持稳定。
    · 若摄入热量 < TDEE(适度减 10–20%),有助于逐渐减脂。
    · 若摄入热量 > TDEE,则更容易增重或增肌。
    In general:
    · If calorie intake ≈ TDEE, body weight tends to stay stable.
    · If intake < TDEE by about 10–20%, this usually supports gradual fat loss.
    · If intake > TDEE, it becomes easier to gain weight or build muscle.
  • 5)局限性与提醒 · Limitations & Reminder:
    本工具仅基于身高、体重、年龄和性别做理论估算,未考虑体脂率、肌肉量、激素水平、健康状况等个体差异。
    The calculation is theoretical and does not consider body fat percentage, muscle mass, hormones, or medical conditions.
    若涉及减重、增肌或疾病管理,请结合专业营养师或医生的个性化建议。
    For weight control, muscle gain or disease management, please consult a dietitian or medical professional.
