What “free” usually means
There are two different “free” approaches:
- Free assistant + manual tracking: you ask ChatGPT for estimates and keep totals yourself (notes/spreadsheet).
- Free tier product: a dedicated tracker that saves your logs and shows totals, with some advanced features paid.
The simplest free workflow (one message per meal)
Estimate calories and macros (protein, carbs, fat). Meal: [what I ate] Portions: [rough amounts] Details: [brand/recipe/cooking method, sauces, oils, drinks] Output: 1) Total calories + macros 2) Assumptions you made

How to make “free” actually work (the anti-drop-off checklist)
- Log immediately after eating. “Later” becomes “never.”
- Use the same template every time.
- Don’t chase precision: aim for consistent estimates.
- Fix the multipliers: oils, sauces, cheese, nuts, drinks.
When a paid tracker is worth it
If you’re repeatedly skipping logs because it’s annoying, you’re paying with consistency. A dedicated tracker is worth it when it reduces friction enough that you actually keep going for weeks and months.
