Is retatrutide, the new triple agonist GLP-1, the next big thing in weight loss (or even rapid fat loss)?

That depends on how the drug works, what the results are, the reality between the headlines and the evidence, and what happens to your weight when you stop.

This episode breaks down retatrutide, the GLP-1, GIP, and glucagon triple agonist behind the largest weight loss numbers ever recorded in this class. It covers the Phase 2 obesity trial and the Phase 3 Triumph results, plus why cross-trial comparisons to semaglutide and tirzepatide deserve skepticism.

We examine the body composition data (or lack thereof), and why a bigger number on the scale just amplifies the stakes for muscle mass, weight regain, and the off-ramp. Especially relevant for adults over 40 who are taking, considering, or planning to come off a GLP-1.

Enroll in Eat More Lift Heavy, the 26-week coached program where adults over 40 build the nutrition and training skills to preserve muscle, lose fat, and manage their physique for life, including support for lifestyle changes needed while taking GLP-1s (and to come off them if desired).
