Why it's defensible

It uses the 770's signature signals that camera-scan and scale-based competitors physically cannot access:

| 770 signal | Drives each week |

|---|---|

| Fat/lean-mass delta | Calorie + macro adjustment |

| ECW/TBW shift | Distinguishes real fat loss from water/inflammation — don't over-cut on a fluid swing |

| Phase angle (whole + segmental) | Training readiness — how hard to program the week |

| Segmental lean | Which body parts the week's training targets |

| Visceral fat, BMR | Goal pacing + baseline energy budget |

The weekly adjustment engine (a real energy-balance + lean-preservation model) computes the numbers; an LLM writes the meal plans and explains the week — the LLM never invents the figures.
