Glucagon-like peptide-1 (GLP-1) can transform metabolic health, but only with smart dosing, adequate dietary protein, regular strength training, and mental health support. 

In this episode, we explore how GLP-1 medications work in the brain and gut, why metabolic health is more than BMI or a weight on the scale, and how to use these drugs safely. Our expert guest, gastroenterologist, Dr Supriya Rao shares practical dosing, side effect strategies, and what makes results stick.

• Defining metabolic health beyond BMI and weight
• How GLP-1s reduce appetite and slow gastric emptying
• Healthy weight loss pace and preserving lean muscle
• Practical + science-backed dosing and individualized titration
• The unknown risks of compounding and microdosing
• Managing nausea, reflux, and constipation
• Diet shifts: smaller meals, more fiber, adequate protein
• Mental health, body image, and stigma in care
• Durability of results and maintenance dosing
• New indications: MASH (metabolic dysfunction-associated steatohepatitis), sleep apnea, cardiovascular protection
• Building an educated care team
