Tracking Body Composition Changes on Retatrutide: What to Measure

A practical guide to tracking body composition on retatrutide therapy — what metrics matter and how often to measure.

Key Metrics to Track

Weight alone doesn't capture the full picture on retatrutide. Key metrics include waist circumference (proxy for visceral fat), DEXA scan body fat percentage, and waist-to-hip ratio. For those without access to DEXA, bioimpedance scales provide useful trend data despite individual measurement limitations.

Photographic documentation at 4-week intervals provides visual confirmation of changes that numbers may miss. Clothing fit is an often-overlooked but reliable indicator of body composition change.

Measurement Frequency

Weight should be tracked daily (with 7-day averaging to smooth fluctuations). Waist circumference weekly. DEXA or bioimpedance monthly. Blood work (lipid panel, HbA1c, inflammatory markers) at baseline, 3 months, and 6 months.
