Free restaurant meal calorie estimator: pick a chain (Chipotle, Chick-fil-A, Panera, Olive Garden, etc.), pick an item, and start from the posted FDA-required menu calories — then add a practical prep buffer because real-world plates are heavier than the lab plate. Once you have the adjusted number, the tool converts the meal into body-weight-adjusted buy-back minutes (walking, rucking, standing) so the cost is something concrete instead of a guilt-trip. Same engine as the CalBurndown app.
