Today we’re cutting through the noise on one of the most talked-about topics in health right now: GLP-1 receptor agonists and weight loss.

These are medications I use with my own patients and they also have caused some controversy on social media so we are going to dispell some myths and dive into the research.

I’m joined by endocrinologist and obesity medicine expert Dr. Karl Nadolsky to unpack the real science behind semaglutide, tirzepatide, and what these drugs actually do in the body — beyond the headlines.

Here’s an overview of what you can expect in this episode:

• How GLP-1 medications like Ozempic actually work ,beyond just weight loss

• The root causes of obesity and why it’s more than just calories in, calories out

• The role of hormones like leptin and insulin in hunger and metabolism

• Why “willpower” isn’t a useful tool in treating obesity

• How weight stigma harms patient care and outcomes

• What to expect when starting GLP-1s — common side effects and who they’re for

• The future of obesity treatment and why it’s shifting toward personalised care
