Nutrition for satiety and weight loss | Dr Federica Amati

GLP-1 medications are now part of the mainstream conversation, but the biology of appetite and satiety, the system these drugs operate within, gets far less attention than the drugs themselves. In this episode, I sit down with Dr Federica Amati, Head Nutritionist at ZOE and author of the new book The Appetite Reset, to explore what's actually happening in the gut and brain when appetite signals do their job, and what that means for everyone, on or off medication. Federica brings a rare combination of pharmacology, clinical nutrition, and public health expertise to a subject that rarely receives this level of nuance. This is a conversation about understanding your biology well enough to work with it. What we cover: How GLP-1 works naturally in the body, why the natural peptide lasts minutes while the drug version lasts days, and why this matters for anyone using or considering these medications The three types of hunger (hedonic, homeostatic, and microbiota-driven) and how to tell them apart in practice Why GLP-1 supplements don't replicate what the medications do "Prehab" before starting medication: gut microbiome diversity, fibre intake, and nutrient status as the foundation Why the 30g daily fibre target doesn't drop when calorie intake does on medication Protein targets of 1.2 to 1.6g per kilogram and resistance training three times a week as the most critical protective interventions for muscle and bone health The science on shame, weight stigma, and why treating obesity as a lifestyle choice is both inaccurate and actively harmful If this episode was useful, a review on Apple Podcasts or a follow on Spotify makes a genuine difference.
