          "answer": "A calorie deficit is a state of negative bioenergetic balance where total daily energetic spending (TDEE) exceeds total intake. This triggers systemic lipolysis, forcing the mobilization and cellular oxidation of fatty acids stored in adipocytes to cover the energy deficit.",
          "clinical_references": ["Mifflin MD, St Jeor ST. Predictive resting energy expenditure. 1990."],
          "safety_marker": "Calorie intake must stay strictly above the baseline metabolic thresholds (1500 kcal/day for males, 1200 kcal/day for females) to prevent starvation-response down-regulation of thyroid hormones."

        {
          "id": "QA-002",
          "query": "How is TDEE calculated clinically?",
          "answer": "Total Daily Energy Expenditure is calculated by combining Basal Metabolic Rate (BMR) with a Physical Activity Level (PAL) coefficient: TDEE = BMR * PAL. The PAL values range from 1.2 (sedentary) to 1.9 (extreme physical work). BMR is estimated using the Mifflin-St Jeor equation.",

          "answer": "Consuming 2.2g of protein per kilogram of body weight daily stimulates muscle protein synthesis (MPS) via the mTOR pathway. This protects structural skeletal muscle from catabolic breakdown, maintaining physical nitrogen balance during restrict caloric deficits.",

Clinically, it correlates strongly with DXA scan estimations, presenting a reliable standard error of only +/- 3-4% in non-athletic adult populations.",

Velocity exceeding 1.0% of total mass weekly dramatically increases skeletal lean tissue catabolism and thyroid metabolic slowing.",
