功能

Features

1. 身体成分分析

1. Body Composition Analysis

BMI计算与分类
  • BMI = 体重(kg) / 身高(m)²
  • 分类标准(WHO亚洲标准):
    • 偏瘦:BMI < 18.5
    • 正常:18.5 ≤ BMI < 24
    • 超重:24 ≤ BMI < 28
    • 肥胖:BMI ≥ 28
体脂率评估
  • 男性:15-20%(正常),20-25%(偏高),>25%(肥胖)
  • 女性:20-25%(正常),25-30%(偏高),>30%(肥胖)
围度分析
  • 腰围评估
    • 男性:< 90cm(正常),≥ 90cm(腹部肥胖)
    • 女性:< 85cm(正常),≥ 85cm(腹部肥胖)
  • 腰臀比
    • 男性:< 0.9(正常),≥ 0.9(腹部肥胖)
    • 女性:< 0.85(正常),≥ 0.85(腹部肥胖)
理想体重计算
  • BMI法:理想体重 = 身高(m)² × 22
  • Broca法修正:理想体重 = (身高cm - 100) × 0.9
BMI Calculation and Classification
  • BMI = Weight(kg) / Height(m)²
  • Classification Standards (WHO Asian Standards):
    • Underweight: BMI < 18.5
    • Normal: 18.5 ≤ BMI < 24
    • Overweight: 24 ≤ BMI < 28
    • Obese: BMI ≥ 28
Body Fat Percentage Assessment
  • Male: 15-20% (Normal), 20-25% (Elevated), >25% (Obese)
  • Female: 20-25% (Normal), 25-30% (Elevated), >30% (Obese)
Circumference Analysis
  • Waist Circumference Assessment
    • Male: < 90cm (Normal), ≥ 90cm (Abdominal Obesity)
    • Female: < 85cm (Normal), ≥ 85cm (Abdominal Obesity)
  • Waist-to-Hip Ratio
    • Male: < 0.9 (Normal), ≥ 0.9 (Abdominal Obesity)
    • Female: < 0.85 (Normal), ≥ 0.85 (Abdominal Obesity)
Ideal Weight Calculation
  • BMI Method: Ideal Weight = Height(m)² × 22
  • Modified Broca Method: Ideal Weight = (Height(cm) - 100) × 0.9

2. 代谢率计算

2. Metabolic Rate Calculation

Harris-Benedict公式(1919原始版)
  • 男性:BMR = 88.362 + (13.397 × 体重kg) + (4.799 × 身高cm) - (5.677 × 年龄)
  • 女性:BMR = 447.593 + (9.247 × 体重kg) + (3.098 × 身高cm) - (4.330 × 年龄)
Mifflin-St Jeor公式(推荐,更准确)
  • 男性:BMR = (10 × 体重kg) + (6.25 × 身高cm) - (5 × 年龄) + 5
  • 女性:BMR = (10 × 体重kg) + (6.25 × 身高cm) - (5 × 年龄) - 161
Katch-McArdle公式(基于瘦体重)
  • BMR = 370 + (21.6 × 瘦体重kg)
  • 瘦体重 = 体重kg × (1 - 体脂率)
TDEE计算
  • TDEE = BMR × 活动系数
  • 活动系数:
    • 久坐:1.2
    • 轻度活动:1.375
    • 中度活动:1.55
    • 高度活动:1.725
    • 非常高度活动:1.9
Harris-Benedict Formula (Original 1919 Version)
  • Male: BMR = 88.362 + (13.397 × Weight(kg)) + (4.799 × Height(cm)) - (5.677 × Age)
  • Female: BMR = 447.593 + (9.247 × Weight(kg)) + (3.098 × Height(cm)) - (4.330 × Age)
Mifflin-St Jeor Formula (Recommended, More Accurate)
  • Male: BMR = (10 × Weight(kg)) + (6.25 × Height(cm)) - (5 × Age) + 5
  • Female: BMR = (10 × Weight(kg)) + (6.25 × Height(cm)) - (5 × Age) - 161
Katch-McArdle Formula (Based on Lean Body Mass)
  • BMR = 370 + (21.6 × Lean Body Mass(kg))
  • Lean Body Mass = Weight(kg) × (1 - Body Fat Percentage)
TDEE Calculation
  • TDEE = BMR × Activity Factor
  • Activity Factors:
    • Sedentary: 1.2
    • Lightly Active: 1.375
    • Moderately Active: 1.55
    • Very Active: 1.725
    • Extra Active: 1.9

3. 能量缺口管理

3. Calorie Deficit Management

每日能量缺口追踪
  • 缺口 = TDEE - 实际摄入 + 运动消耗
  • 缺口达标分析:实际缺口 vs 目标缺口
减重估算
  • 1kg脂肪 ≈ 7700大卡
  • 预计周减重 = 每日缺口 × 7 / 7700
  • 安全减重速度:0.5-1kg/周(缺口500-1000大卡/天)
热量安全边界
  • 男性最低热量:1500大卡/天
  • 女性最低热量:1200大卡/天
  • 绝对最低:BMR × 1.2
Daily Calorie Deficit Tracking
  • Deficit = TDEE - Actual Intake + Exercise Expenditure
  • Deficit Compliance Analysis: Actual Deficit vs Target Deficit
Weight Loss Estimation
  • 1kg of fat ≈ 7700 kcal
  • Estimated Weekly Weight Loss = Daily Deficit × 7 / 7700
  • Safe Weight Loss Rate: 0.5-1kg/week (500-1000 kcal/day deficit)
Calorie Safety Boundaries
  • Minimum Calories for Males: 1500 kcal/day
  • Minimum Calories for Females: 1200 kcal/day
  • Absolute Minimum: BMR × 1.2
