You might think the number dropping on the scale is the whole win, but on a GLP-1, a meaningful share of what you're losing may be muscle, not fat, and the fiber that's supposed to help can quietly make things worse.

In this solo episode, Dr. Gabrielle Lyon discusses:

Why 25–40% of the weight lost on GLP-1 medications can be lean mass, and how to protect your muscle with adequate protein (1.2–1.5 g/kg) and resistance training
The GLP-1 fiber paradox and why these drugs need fiber to work, but make it hard to tolerate, and why 40–70% of patients hit GI side effects like bloating and constipation
When to fiber max vs. fiber mine, plus how to reintroduce fiber gradually so you get the gut benefits without the bloat, bezoars, or obstruction risk

Get this balance right, and you keep your muscle, calm your gut, and let the medication do its job instead of ending up bloated, constipated, and quietly losing strength.
