After eight months on a calorie-deficit plus Peloton routine I stalled at 23% body fat. My DPC physician suspected I was in a 'skinny-fat' cul-de-sac—dropping scale weight but cannibalizing muscle. She prescribed a BodySpec DEXA scan to map lean-mass vs. fat. The scan showed 38% of my lost weight was muscle mass, and visceral fat had barely budged. She pivoted my macros to 1.8 g/kg protein, added two weekly compound-lift sessions, and upped carbs around workouts. We re-scanned six weeks later: lean mass was +2.3 lbs, visceral fat -0.8 lbs, resting metabolic rate +87 kcal/day. That visual proof erased 'scale anxiety' and kept me compliant—plateau shattered." Results (bullet) * Scale weight [?]4 lbs but body-fat % [?]2.7 * Visceral fat mass [?]15 % * Deadlift +40 lbs Why It's Unique Using a medical-grade DEXA as a feedback loop let a DPC doctor individualize macros and training—no trial-and-error, just data-driven correction.
