Does Survodutide help with liver fat and visceral fat?

B
Grade B — probable, not settledPhase 3 (SYNCHRONIZE-MASLD) · effect size: large
Short answerProbable, not settled. Human data exist (Phase 3 (SYNCHRONIZE-MASLD)) and mostly agree, showing a large effect — but too few, too small, or not yet peer-reviewed for a firm answer. Marked reductions in liver fat and visceral fat reported in the phase 3 obesity-with-MASLD trial; consistent with the glucagon component's hepatic action.

What the studies show

Marked reductions in liver fat and visceral fat reported in the phase 3 obesity-with-MASLD trial; consistent with the glucagon component's hepatic action.

Human trials exist and mostly agree, but there are too few of them, they are too small, or one big one is still reading out. Expect the grade to move.

In context

Survodutide is a once-weekly peptide that activates both the GLP-1 and glucagon receptors. In SYNCHRONIZE-1, a 725-person phase 3 trial published in June 2026, it produced 12–13% weight loss at 76 weeks against 5% on placebo, with gastrointestinal symptoms in up to 90% of participants. Its distinctive result is in the liver: a phase 2 trial resolved MASH without worsening fibrosis in 83% of patients at the top dose. It is not approved anywhere.

Survodutide is investigational. Legal status differs by country — see the regulation section or the jurisdiction pages.
