    "coachSummary": "To lose 7.0 kg in 20 weeks, you need a daily deficit of 385 kcal — eating 2,015 kcal/day. That's 0.35 kg per week, reaching your target by March 22, 2027. Energy expenditure falls as weight comes off, so real loss usually slows; treat the later weeks of this straight-line projection as optimistic."
