In June 2025, Eli Lilly announced that its highest approved doses of Zepbound (12.5 mg and 15 mg) would be made available in single-dose vials for USD 499/month through LillyDirects Self Pay Journey Program

This fundamental mechanistic difference has implications for metabolic effects, hepatic fat handling, and potentially which patient populations benefit most

Studies have shown that GLP-1 release is influenced by: Dietary fiber , particularly fermentable fibers Protein intake , especially when evenly distributed across meals Healthy fats , which slow digestion and enhance satiety signaling Gut microbiome activity , which plays a direct role in GLP-1 secretion These factors help explain why whole-food diets rich in fiber and protein are consistently associated with better appetite regulation and metabolic health

If GLP-1 drugs can give those living with mental illnesses and neurodegenerative diseases reprieve, I would compare it to some of the major breakthroughs of the history of medicine, Rascol says
