Editor's note

This is a preclinical study in diet-induced obese mouse and hamster models, so results are early and not human data. Retatrutide was associated with marked weight loss, lower HOMA-IR, and reduced hepatic triglycerides, though it did not improve liver histopathology scores. The work primarily validates the models for testing obesity and MASH therapies.

Plain-language abstract

In obese mouse and hamster models, retatrutide reduced body weight and was associated with improvements in insulin resistance, blood lipids, and liver fat content.
