Use this when you need daily maintenance calories for an adult, or calorie targets for a mild/standard deficit or surplus. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when the person is a child, pregnant or breastfeeding, or you only need the resting rate (use bmr). What it computes: Estimates total daily energy expenditure from Mifflin-St Jeor BMR and an activity level, and derives calorie targets for maintaining, losing or gaining weight. Inputs: sex (enum); weight_kg (number, kg); height_cm (number, cm); age_years (number, years); activity_level (enum, optional). Complete JSON argument examples: {"sex":"male","weight_kg":70,"height_cm":175,"age_years":30,"activity_level":"moderate"} Outputs: bmr_kcal_per_day [kcal/day], activity_multiplier, tdee_kcal_per_day [kcal/day], mild_loss_kcal_per_day [kcal/day], loss_kcal_per_day [kcal/day], mild_gain_kcal_per_day [kcal/day], gain_kcal_per_day [kcal/day]. Formula: TDEE = BMR(Mifflin-St Jeor) × activity_multiplier; targets = TDEE ± 250 or ± 500 kcal/day Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/tdee with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/health/tdee.md
