The missing piece in weight loss— your psychology
The essential guide to making GLP-1 medications work long-term, with a comprehensive 12-session psychological programme for lasting change.
Why medication alone isn't enough
GLP-1 medications like Wegovy and Mounjaro have transformed weight management. They work. But there's a problem no one talks about: what happens when you stop?
Oxford University research (2026) found it takes just
1.5 years
to regain all weight lost after stopping GLP-1 medication without psychological support
The reason? People haven't done the psychological work needed to change their relationship with food and their body for the long term. The medication quiets the "food noise," but it doesn't address the emotional eating patterns, the self-worth issues, or the decades of conditioning that got you here.
That's exactly why we wrote this book.
What this book offers
The Knowledge
Everything you need to understand about GLP-1 medications: how they work, who they're for, side effects, dosing strategies, and why most approaches fail. Written by a psychiatrist with medical expertise.
The Programme
A 12-session psychological programme drawing on over 20 years of eating disorders and weight management expertise. Evidence-based techniques from CBT, compassion-focused therapy, and behavioural science.
Lasting Change
This isn't another diet book. It's a guide to fundamentally transforming your relationship with food while the medication gives you breathing room, so when you're ready to stop, the changes stick.

"Obesity is usually a symptom of something else, fuelled by underlying issues relating to self-worth, mood, the need for comfort, or a sense of shame. What's happening in your mind is being played out in your body and the food you eat."
