Proposed Update to Our Nutrition Scoring System
(Concise version for developer review)
Our current scoring model has several major issues:
• Undercounts vegetables (excludes greens powders, potatoes, peas, corn).
• Over-penalizes red meat (immediate score drop).
• Does not adjust to user goals or activity level.
• Relies on daily scoring instead of weekly trends.
• Uses punitive logic that discourages consistency.
Below is the proposed replacement — simpler, more accurate, and more supportive for real human behavior.
⸻
  1. Weekly-Based Scoring (Core Fix)
Nutrition should be evaluated as patterns, not individual days.
Final Weekly Score = 60% Quality Score + 40% Macro Alignment
⸻
  1. Quality Score (A-AQS)
Daily points averaged over the week.
Positive Points
• Vegetables: +1.5
• Greens powders: +1.5
• Dark leafy greens: +0.5 bonus
• Fruit: +1
• Whole grains/complex carbs: +1
• Starchy veggies (potatoes, peas, corn): +1.5
• Lean protein/fish: +1.5
• Legumes: +1
• Healthy fats: +0.5
• “Small Wins” bonus: +1 for 3+ categories/day
These solve our current undercounting issues.
Negative Points (Adaptive)
Red Meat (Weekly):
0–3 servings → 0
4–5 → −0.5
6+ → −1
Processed / High-Sugar Foods:
Deficit: −1.5
Maintenance: −1
Surplus/Active: −0.5
Highly Active: subtract an additional 0.5
Sodium:
Sedentary >2300mg: −1
Moderate >3000mg: −0.5
Highly active: no penalty
This removes one-size-fits-all punishment.
⸻
  1. Goal-Weighted Macros (GWMS)
Users set Primary, Secondary, Tertiary priorities.
Points:
• Primary met: +3
• Secondary: +1.5
• Tertiary: +0.5
Activity-adjusted adherence windows:
• Low: ±5%
• Moderate: ±7%
• High: ±10–12%
⸻
  1. Tier System
• Bronze: 4+ nutrient servings + partial macro alignment
• Silver: 6+ servings + 2 macro goals
• Gold: 8+ servings + all macro goals
Focus is on progress, not perfection.
⸻
  1. Developer Implementation (Simplified)
Inputs:
User goal, activity level, daily macro intake, macro targets, food categories, sodium, processed count, weekly red meat count.
Daily A-AQS:
sum(positive) − sum(adjusted negatives)
Weekly Red Meat Penalty:
apply once at week end.
GWMS:
Check goals → assign points based on priority + activity-adjusted windows.
Weekly Score:
weekly = (avg A-AQS × 0.6) + (avg GWMS × 0.4)
Tier Assignment:
Gold/Silver/Bronze based on unified thresholds.
⸻
  1. User Messaging Tone (Short Version)
Replace punitive language with supportive framing:
• “Let’s look at your weekly trend”
• “This choice still contributes to your goal”
• “Training days may increase your needs”
This prevents shame cycles and increases long-term adherence.
⸻
Summary
This model fixes the flaws in the current scoring by:
• Counting all legitimate nutrient sources
• Removing harsh or arbitrary penalties
• Adapting scoring to personal goals + activity level
• Using weekly averages to support consistency
• Providing clear logic for developers to implement
It’s simple, accurate, sustainable, and aligned with the behavioral patterns nutritionists want to encourage.
