- GPT Action Weight Loss Coach Actions > calculateBMR(Compute basal metabolic rate (BMR)): Returns Mifflin-St Jeor BMR. CALL THIS instead of doing the math yourself. Pass user_id to persist the profile for future conversations. Echo the returned narrative verbatim.
- GPT Action Weight Loss Coach Actions > calculateTDEE(Compute total daily energy expenditure (TDEE)): Returns TDEE = BMR × activity multiplier. Call this before recommending a calorie goal. Pass user_id to persist the full profile. Echo the returned narrative verbatim.

Enforces calorie floors (1200F/1500M/1600 teen), BMI <19 screen, 1kg/week rate cap, and pregnancy refusal. The `narrative` field is what the GPT should say — do not propose your own numbers on top of this.
- GPT Action Weight Loss Coach Actions > calculateMacros(Compute protein/fat/carb grams for a daily calorie goal): Returns macros based on weight and preference. Protein is pinned to 1.2–1.6 g/kg (balanced), 1.8 g/kg (high_protein), or 1.6 g/kg (keto). Echo the narrative verbatim.

- GPT Action Weight Loss Coach Actions > smoothWeightTrend(De-noise a weight history and return the real fat trend): Applies a 7-day EMA to filter out water-weight noise, then regresses the last 14 smoothed points for a kg/week slope.

Returns ranked likely causes and ONE specific adjustment. Call this when the user reports 2+ weeks of no change. Echo the narrative verbatim.
