Deploy to Render (free 24/7 hosting)
Push code to GitHub Go to render.com → New → Web Service → connect your repo Build command: pip install -r requirements.txt Start command: python discord_bot.py Add environment variables: DISCORD_BOT_TOKEN and ANTHROPIC_API_KEY Set PYTHON_VERSION = 3.11.9 in environment variables Turn Auto-Deploy OFF — deploy manually to avoid Discord rate limits Click Deploy
Note: If you see a 429 error on first deploy, wait 10 minutes then redeploy manually. This is Discord temporarily blocking Render's IP after multiple rapid login attempts during setup. It clears on its own.
How Food Search Works When you type 200g grilled skinless chicken breast: Stage 1 — Search Open Food Facts as typed ↓ not found Stage 2 — Strip cooking words (grilled, skinless...) Try: "chicken breast fillet" → "chicken breast" → "chicken" ↓ still not found Stage 3 — Ask Claude AI with web search enabled Claude searches the internet for the macros Returns structured data → logged with AI badge
How the Calorie Target is Calculated BMR = Mifflin-St Jeor formula (based on gender, age, weight, height) TDEE = BMR × activity multiplier Daily change = (weekly_rate_g × 7.7 kcal) ÷ 7 days
Goal = lose → target = TDEE - daily_change Goal = gain → target = TDEE + daily_change Goal = maintain → target = TDEE
Floor: never below 1500 kcal (male) or 1200 kcal (female)
