Formula & Theory — Healthy Lifestyle Calculator
The Healthy Lifestyle Calculator uses a four-pillar weighted scoring system totaling 100 points.
Diet Score (max 30 pts)
Fruit & Vegetable Score = min(servings / 5, 1) × 15
Processed Food Score = max(0, (5 − level) / 5) × 15
Diet Score = Fruit & Vegetable Score + Processed Food Score| Input | Range | Max Points |
|---|---|---|
| Fruits & Vegetables | 0–7+ servings | 15 |
| Processed Food Level | 0 (none) – 5 (very heavy) | 15 |
Exercise Score (max 30 pts)
Duration Score = min(minutes / 60, 1) × 20
Type Bonus = 0 (sedentary) | 3 (light) | 7 (moderate) | 10 (intense)
Exercise Score = min(Duration Score + Type Bonus, 30)Sleep Score (max 25 pts)
Hour Score = 15 (7–9 h) | 10 (6–7 h or 9–10 h) | 5 (5–6 h or >10 h) | 0 (<5 h)
Quality Score = ((quality − 1) / 4) × 10
Sleep Score = min(Hour Score + Quality Score, 25)Hydration Score (max 15 pts)
If liters ≥ 2.0 → 15 pts
If 1.5 ≤ liters < 2.0 → linear scale 5–15 pts
If 0.5 ≤ liters < 1.5 → linear scale 0–5 pts
If liters < 0.5 → 0 ptsTotal Healthy Lifestyle Index
