Section 01 - Engagement
How the population engaged over time.
Daily SMS check-ins and habit completion drive the behavioral change that produces DEXA outcomes. Both metrics strengthened consistently across the year.

Members averaged 3.4 active habits simultaneously. Nutrition habits showed the highest sustained adherence at 79% weekly completion.
Section 02 - DEXA Outcomes
Body composition results, verified by scan.
Population averages across three scan intervals - baseline (month 0), mid-point (month 6), and final (month 12). 573 members completed all three scans; 681 completed at least two.

Section 03 - Cohort Analysis
Results by program engagement tier.
Members are grouped by SMS response rate over the full 12 months. Higher engagement tiers show consistently stronger DEXA outcomes - validating the behavior-change model.
Engagement tier Members Avg SMS rate Habit adherence Visceral fat Δ Body fat Δ Improved
High (>80%) 341 88% 81% −23.1% −3.8 pp 91%
Mid (50–80%) 386 64% 68% −14.8% −2.4 pp 72%
Low (<50%) 120 34% 41% −4.2% −0.6 pp 38%
Key finding
Engagement predicts outcomes with high fidelity.
Members in the high-engagement tier reduced visceral fat by more than 5× compared to the low-engagement group. This confirms that daily behavioral touchpoints - not just DEXA scans alone - are the active ingredient.
Recommendation
Bring the low-engagement cohort up to 50%+.
The 120 members in the low-engagement tier represent the biggest opportunity for Year 2. A targeted re-engagement campaign - adjusting check-in timing, habit difficulty, or coaching frequency - could move 60–80 members into the mid tier and materially shift population outcomes.
