Dr Almerie compares Lilly's experimental retatrutide with Mounjaro and talks through the case for switching versus holding off until it's approved.
He points to GLP-1 receptors in the hypothalamus, saying the medication boosts fullness signals and slows the stomach, which changes how hunger feels.

Weight loss doctor Bazgha Khalid goes through what the published trials actually show for Zepbound against Lilly's newer retatrutide.
Patients who took a GLP-1 receptor agonist before surgery did not lose more weight at one year, JAMA Surgery reports. The full study has the details.
Bikman calls the results remarkable, but he argues that bigger drops make it more important to know how much of the lost weight is fat and how much is muscle.
Bikman points out that weight usually returns once the drug is stopped, which makes the question of lifelong use a real one.
