Nutrition Tracker (Obsidian)

This skill logs meals (kcal + P/C/F) into an Obsidian vault and maintains daily totals. It also stores a lightweight nutrition profile (sex/height/weight/activity/goal) and can evaluate whether today's intake meets targets.

i18n: scripts support --lang zh-CN|en-US (default: zh-CN).

Storage

• Vault (default): ~/Documents/obsidian/yzhai-daily
• Profile: health/eat/profile.json
• Monthly log: health/eat/YYYY-MM/YYYYMM_calories_macros.md

Quick start

1) Initialize / update profile

bash ~/.openclaw/workspace/skills-public/nutrition-tracker/scripts/nutrition_init.sh \
  --sex male \
  --height 175 \
  --weight 75 \
  --activity office \
  --goal cut \
  --kcal 2200 \
  --lang zh-CN

2) Log a meal

bash ~/.openclaw/workspace/skills-public/nutrition-tracker/scripts/nutrition_log.sh \
  --date "2026-03-04" --time "19:54" --meal dinner \
  --desc "rice 150g; potato 120g; meat+egg 200g; soup 200g" \
  --kcal 830 --p 45 --c 69 --f 40 \
  --lang zh-CN

3) Check whether today's targets are met

bash ~/.openclaw/workspace/skills-public/nutrition-tracker/scripts/nutrition_check_today.sh \
  --date "2026-03-04" \
  --lang zh-CN

Target logic (defaults)

If profile has no explicit macro targets, defaults are computed by goal:

• cut (fat loss):
  • Protein: 2.0 g/kg
  • Fat: 0.8 g/kg
  • Carbs: remaining calories (based on kcal target)

You can override targets explicitly in profile (see nutrition_init.sh --pTarget/--cTarget/--fTarget).

Notes

• Keep meal macros as estimates; refine later by updating entries.
• This skill is designed to be deterministic via scripts, not free-form editing.
