The scale can't tell you if you're losing fat or muscle. The InBody 580 can.
Metronome uses the InBody 580 — the same professional-grade body composition analyzer used in research and sports-medicine settings — to track fat loss, muscle mass, and hydration in 30 seconds. It's built directly into your GLP-1, hormone, and midlife optimization care, read by your physician, not printed and handed over.
A Clinical-Grade Look Beneath the Scale Number
The InBody 580 uses bioelectrical impedance analysis (BIA) — a safe, painless current run through hand and foot electrodes — to break your weight down into what actually matters: how much is fat, how much is muscle, and how it's distributed across your body. Segmental analysis of each limb and your trunk gives Dr. Juan insight into your current health status, potential areas of inflammation, and which nutrition and training approach will actually work for you — not just a number on a scale.
Body Fat %
Your true fat mass, not a BMI estimate that can't tell a muscular frame from an overweight one.
Skeletal Muscle Mass
Tracked segmentally — arms, legs, and trunk individually — so muscle loss shows up long before it's visible.
Visceral & Segmental Fat
The metabolically active fat around your organs, which matters more for health risk than total weight.
Phase Angle
An advanced marker of cellular health and nutrition status the InBody 580 measures segmentally — most consumer scales can't.
Total Body Water
Hydration status broken into intracellular and extracellular water — useful context for GLP-1 patients and hormone therapy alike.
Basal Metabolic Rate
The calories your body burns at rest, calculated from your actual muscle mass — not a generic height/weight formula.
Lose the Fat. Keep the Muscle.
Weight loss is not the same as fat loss. GLP-1 medications are remarkably effective at shrinking the number on the scale — but research consistently shows that roughly a quarter to as much as 40% of the weight lost on any aggressive weight-loss plan, including GLP-1 therapy, can come from lean muscle if protein intake and resistance training aren't dialed in.
That's the difference between weight loss and body recomposition. At Metronome, InBody scans are part of your GLP-1 protocol — a baseline scan before you start, then rechecks roughly every 2–3 months — so if muscle is dropping faster than fat, Dr. Juan can adjust your protein targets, your training guidance, or your dose before it shows up as a problem, not after.
Learn About Medical Weight Loss →of total weight lost during GLP-1 therapy can be lean mass rather than fat — unless it's actively monitored and countered with adequate protein and resistance training. Metronome tracks this directly instead of leaving it to the scale.
The One Number That Predicts More Than Blood Pressure
A landmark study following over 140,000 people across 17 countries, published in The Lancet, found that grip strength predicted all-cause mortality more strongly than systolic blood pressure. It's now considered one of the simplest, most reliable biomarkers of healthy aging — tied to cardiovascular health, cognitive function, and long-term independence.
Metronome uses a hand dynamometer alongside InBody scanning to track your grip strength over time — a functional, real-world check on whether the muscle mass your InBody scan shows is actually translating into strength, especially important through midlife and during any weight-loss protocol.
Built Into Your Care, Not Sold as an Add-On
Baseline Scan
An InBody 580 scan and grip strength check at your first visit — takes minutes, no prep required.
Physician Interpretation
Dr. Juan reads the segmental results himself and folds them into your GLP-1, hormone, or midlife vitality plan — not a generic printout.
Ongoing Rechecks
Rescans roughly every 2–3 months track real change — fat down, muscle preserved, strength holding — and adjust your plan accordingly.
Rescan frequency and any associated cost are set by your current membership terms and may be adjusted over time.
Same Device the Gold-Standard Clinics Use. A Physician Actually Reads It.
A stand-alone body composition scan at a gym or rec center front desk usually runs $20–50 and hands you a printout to interpret yourself. A DEXA scan is more precise but often costs $200 or more per visit and isn't paired with anyone managing your medication or training.
At Metronome, InBody and grip strength monitoring are part of the same coordinated relationship as your GLP-1 prescribing, your hormone therapy, and your primary care — read by the one physician who's adjusting your plan, not a machine you interpret alone.
