The Claim

Once-weekly subcutaneous retatrutide is associated with an 18.4-fold higher likelihood of achieving at least 15% body weight loss compared to placebo in adults with overweight, obesity, and/or type 2 diabetes, indicating that a high proportion of patients may reach clinically transformative weight loss thresholds.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

People who get a weekly shot of a new medicine called retatrutide are about 18 times more likely to lose at least 15% of their body weight than those who get a placebo, which could mean a lot of them reach a weight loss level that really improves their health.
