Vietnamese food understanding for a safe weight-loss coach

• Match at least 90% of the 100 most common Vietnamese foods and drinks from a natural description on the first try, and ask instead of guessing when unsure. • Build standard recipes for Vietnamese dishes from sourced ingredients, so every figure can be traced, and have a partner nutrition expert review them. • Screen before planning: no calorie-cutting plan for minors, pregnancy, low body weight or disordered eating; doctor-first for medical conditions; emergency replies that don't depend on a model. • Keep health data private: explicit consent, export and deletion, no model training, and only model providers that don't train on or review user content. We're looking for a partner dietitian or doctor to review the coach's rules and figures.
