A Matter of Fat

A Matter of Fat

The show for anyone who's got no idea what they think about weight in 2026

Ozempic, Mounjaro and Wegovy have changed the conversation around weight and bodies faster than any of us has managed to think it all through. The weight-loss drugs, the diets, the shame, the money and the judgement have left most of us with no idea what we think anymore. Is thinner really better? Or healthier? What is the social and emotional cost of a life spent pursuing it? And can't we all just be kinder to each other?

Each week, journalist Rose Stokes and Professor Giles Yeo MBE, one of the world's leading obesity scientists based at Cambridge University, take on a different part of the conversation nobody can quite get straight. One of them brings the science, the other brings thirty years of lived experience. Neither pretends to have it figured out — and they don't always agree.

Honest conversations about GLP-1 weight-loss drugs and what they actually do to your body, food noise, why diets fail, semaglutide and the science behind it, what Ozempic is doing to body positivity, ultra-processed food, weight stigma, and who can afford to escape judgement and who can't.

Plus two regular segments: Fat Check, testing the science of the internet's wildest weight-loss myths, and Diets I've Survived, rating diets so you don't have to.

New episodes every Tuesday. Follow now so you don't miss one.

Life after willpower... how do we know when to stop?

Now you can change your body, do you still have to love it?

If you can now change your body, do you still have to love it? And can wanting to lose weight coexist with body acceptance? Hosted by journalist Rose Stokes, who brings 30 years of lived experience with weight and obesity, and Dr Giles Yeo, a University of Cambridge scientist who has spent three decades studying why people are small, medium or large in our food environment, this podcast brings together lived experience and science without pretending to have all the answers. In this episode, Rose and Giles explore what happened to body positivity and where it leaves us in the age of GLP-1 weight-loss medication. In a deeply personal conversation, Rose reflects on what the movement meant to her, the disappearance of bigger bodies from fashion and media, and why choosing to lose weight doesn’t mean abandoning everything she believes about acceptance. We cover: • Whether BMI is scientifically meaningless, or simply too limited to tell the whole story • The “SkinnyTok” claim that hunger is a good thing • Why…

They made us fat. Now they're selling us thin.

Big Food helped create the obesity crisis. Should the same industry be allowed to profit from the solution?

Food Noise vs Jab Noise: Which is Louder?

Episode 3: GLP-1 medications might quieten food noise, but has the noise around weight-loss jabs become impossible to escape? A Matter of Fat is a podcast for anyone who has no idea what they think about weight, bodies and the rapidly changing conversation around them. Hosted by journalist Rose Stokes, who brings 30 years of lived experience with weight and obesity, and Dr Giles Yeo, a University of Cambridge scientist who has spent three decades studying how the brain influences appetite, this podcast brings together lived experience and science without pretending to have all the answers. In episode three, Rose and Giles explore food noise, the impact of GLP-1 medications on appetite and the relentless advertising making weight loss increasingly difficult to escape.

It is legislation enforced by the MHRA, and breaching it is a criminal offence.…
