Nutrition & Body Composition

Track what you eat, change how you look. Measurement-backed at every outcome — no scale photos.

A nutrition path with one required foundation — 90 days of macro tracking — and six elective body-composition outcomes. Starts with awareness (what you actually eat) before prescribing change. Every body-composition outcome requires body-scan proof, not visual comparison.
