Nutri Calc (nutri-calc)

Nutrition analysis tool with a 2000+ entry Chinese food database. Accepts natural language food descriptions ("一碗牛肉面", "三两饺子"), calculates TDEE and macro targets from user profile, compares intake vs goals, identifies gaps, and suggests corrective meals.

Workflow

  1. Parse natural language — accept free-text meal descriptions (e.g. "早餐两个鸡蛋+牛奶, 午餐红烧牛肉饭+可乐"). Segment into individual food items. Estimate portion sizes from common Chinese serving units (碗, 份, 两, 个, 杯, 盘). Handle regional dish variants.
  2. Query nutrition database — look up each item from the Chinese food composition database. Return: calories, protein (g), fat (g), carbs (g), fiber (g), sodium (mg) per 100g or per serving. Fallback: estimate from similar dishes when exact match missing.
  3. Calculate daily requirements — use user profile (weight, height, age, gender, activity level) to compute:
    • BMR (Mifflin-St Jeor formula)
    • TDEE (BMR × activity multiplier)
    • Macro split by goal: muscle gain (40P/30F/30C), fat loss (35P/25F/40C), maintenance (30P/25F/45C)
  4. Compare intake vs targets — for each meal and cumulative daily total, show: actual vs target for calories and each macro. Color-code (green = on track, yellow = 10-20% off, red = >20% off).
  5. Gap analysis — identify specific macro shortfalls or excesses:
    • "Protein shortfall 20g → you need ~100g chicken breast or 2 eggs + 1 cup milk"
    • "Carbs excess 40g → consider reducing rice portion by 1/3 at dinner"
  6. Smart supplement suggestions — for identified gaps, suggest realistic Chinese-diet additions: "备选: 加一份卤牛肉(30g蛋白) 或 一杯豆浆(10g蛋白+健康脂肪)". Consider meal time and meal balance.
  7. Multi-day tracking — accept consecutive day inputs. Plot trend: daily caloric surplus/deficit, macro consistency, weekly averages. Alert on drastic swings.
  8. Output — nutrition report: per-meal breakdown table + daily totals vs targets + radar chart (5 dims) + gap fill suggestions + trend summary for multi-day. Export as Markdown or screenshot-friendly text block.
