Ask most business leaders how they measure their health, and the answer is usually weight. Maybe BMI. Possibly cholesterol from an annual physical. These metrics are better than nothing — but they're the equivalent of running your company off monthly revenue alone, with no visibility into margins, burn rate, or unit economics. Body composition is the metric that actually predicts health outcomes, longevity, and performance. And most business leaders have never measured it properly.
Body weight is a single-dimensional number that tells you almost nothing useful. Two people can weigh the same 185 lbs and have completely different health profiles — one with 15% body fat and strong lean mass, the other with 32% body fat and low muscle. The scale cannot distinguish between muscle and fat. It cannot tell you where your fat is stored (subcutaneous vs. visceral). It cannot measure bone density. It is a deeply limited metric for evaluating human health.
Yet most annual physicals, most health insurance assessments, and most casual health conversations center on it. Business leaders who make decisions based on incomplete data in their companies apply ironically better epistemics there than they do to their own bodies.
Body composition breaks down your physical structure into meaningful components:
Lean muscle mass: The engine of your metabolism. Higher lean mass means better insulin sensitivity, more caloric burn at rest, stronger structural support, and better recovery from physical stress. Muscle mass is also one of the strongest predictors of all-cause mortality in longitudinal studies — more than almost any other single metric. Building and preserving lean mass is arguably the highest-leverage health investment a business leader can make.
Visceral fat: The fat stored around your internal organs — not the subcutaneous fat you can pinch, but the metabolically active fat inside your abdominal cavity. Visceral fat secretes inflammatory cytokines, drives insulin resistance, elevates cardiovascular risk, and impairs hormonal function. You can have a "normal" BMI and a dangerously high visceral fat level. DEXA scans and advanced body composition assessments can quantify this precisely.
Bone density: Often overlooked until it's a problem. Bone density peaks in your 30s and declines with age, accelerated by sedentary behavior, low testosterone, poor nutrition, and high cortisol. For business leaders, low bone density is a silent vulnerability — no symptoms until a fracture. Measuring it gives you years of lead time to intervene.
The gold standard is DEXA (Dual-Energy X-ray Absorptiometry) scanning — the same technology used to measure bone density, now applied to full-body composition. A DEXA scan gives you lean mass, fat mass, regional fat distribution (including visceral fat), and bone density in a single 10-minute assessment. It's precise, reproducible, and gives you a baseline you can actually track over time.

At Stark, we use DEXA as part of every new member's baseline assessment — because you can't improve what you haven't measured accurately.
For business leaders in their 40s and 50s, the research-backed targets worth pursuing:
