Effects of Retatrutide on Body Composition: MRI-based Analysis of Fat Distribution
Samson SL, Velasquez MA, Darcourt J, et al.
Obesity, 2024 · n = 187
Key finding
Retatrutide preferentially reduced visceral fat (34% reduction at 15mg) versus subcutaneous fat (19% reduction), with minimal muscle loss despite 22% total weight reduction.
Summary
Mechanistic substudy using MRI to characterize changes in visceral fat, subcutaneous fat, and muscle mass with retatrutide versus placebo.
