The Truth About GLP-1s, Food Noise & Weight Loss Drugs: Dr Federica Amati

GLP-1 weight loss drugs are changing medicine, but are we talking about them in the right way? In this episode, Dr Karan Rajan speaks with Dr Federica Amati about GLP-1s, food noise, metabolic health, appetite, gut health, muscle loss, side effects and why nutrition support matters.

Dr Federica Amati explains why these medications should not be seen as simple “weight loss drugs”, how food noise differs from real hunger, and what people should know before, during and after GLP-1 treatment.

In this conversation, we cover:

* Why diet remains one of the biggest drivers of chronic disease

* What GLP-1s actually do beyond weight loss

* The difference between homeostatic hunger, hedonic hunger and microbiome-driven hunger

* Why food noise can dominate appetite and eating behaviour

* How protein and resistance training can help protect muscle

* Why micronutrients, fibre and hydration matter on GLP-1s

* The risks of black market or poorly regulated weight loss injections

* How gut health may influence appetite, side effects and long-term success

* Why whole foods and nutrient density still matter most
