Zoe Knight is a clinical nutritionist and co founder of Muscle Nerds, with a Bachelor of Health Science in Clinical Nutrition. She's recently moved back into clinical practice, and what she's seeing across two very different client groups has changed how she thinks about health.

This one gets into the taboo territory properly. We talk GLP-1s without the dogma: whether the medication is being used to build agency or to avoid it, why being on one is the easiest window someone will ever get to install the habits, and Zoe's view that you can use a GLP-1 as a tool but can't be optimally healthy on one long term. She also covers the part almost nobody talks about, what rapid fat loss actually does when environmental toxins come out of fat cells, and why supporting detox pathways means protein, nutrients, hydration and actually going to the toilet, not juice cleanses.

Underneath the medication conversation is the bigger one. The single biggest predictor Zoe sees of whether someone changes is their view of themselves. We talk about the research showing most chronically obese clients have experienced trauma and how that reframes the whole approach, the difference between an explanation and an excuse, and why you're not responsible for your first thought but you are responsible for your second. Plus the questions Zoe asks in clinic that tell her everything (how do you feel when you miss a meal, when you overeat, when someone comments on your body), why she asks "what do I notice about myself" instead of "why do I feel this way", and what clients are actually willing to trade.

We also get into why optimal and practical are different things, holding the sunk cost fallacy while finishing a degree, and why it's possible for two experts to say opposite things and both be right.
