In this episode, I explore how we can protect ourselves in a food environment that’s designed to overwhelm us. I talk about why eating well can feel so hard - not because we lack willpower, but because we’re living in a system that constantly cues us to eat and rarely gives our brains a break.
I’ll share practical, psychology-based strategies to reduce your exposure to food triggers, set up helpful defaults for when you’re tired or stressed, and support your mental health so you’re not relying on willpower alone.
If you’ve ever felt like you’re failing when it comes to making food choices this episode is for you.

After a 3-year break, I'm back and diving into one of the most misunderstood topics in psychology and nutrition: control over food.
In this episode, I unpack why so many of us feel out of control with our eating, and why that has much more to do with our food environment than with willpower. From the structure of the brain to the layout of your local Tesco, I break down how our behaviour around food is driven by powerful, automatic processes evolved to keep us alive.
If you've ever felt shame around your eating habits, or told yourself “I should just try harder,” this episode is for you.

In this podcast, I explore the reasons why people might make excuses or come up with reasons not to engage in health behaviours.
Of course, people's reasons are valid, however we sometimes try and poke holes in the reasons. I wanted to dive into some of the deeper reasons why someone may, consciously or subconsciously, come up with a reason not to engage in a health behaviour.

In this episode I speak to Clinical Psychologist Dr. Sophie Mort, who speaks to me about emotions, the purpose of them, the importance of paying attention to them and also the harm in neglecting them.
Sophie's book is called "A Manual for Being Human". Her book explores all aspects of life, from birth to where you are right now, giving us an entire foundation of understanding the human experience.

On this episode I'm lucky to be joined by Dr Mike Banna. Personally, I really enjoy Mike's discussions online - he adds so much nuance and balance to very black or white conversations and this is no different!
I think Mike is a really great example of how weight loss is not ALWAYS a bad thing for people, while recognising the harm it has for others.

In this new short series, I dive into some of the things that mental health professionals commonly hear in the therapy room!
Just as a precursor to the podcast, these are general things that therapists might hear from clients and they are not specific to the people I work with or the clinicians I work worth.

In addition, it’s important to remember that everyone is at a different stage of their journey when it comes to mental health and it’s important not to compare where you’re at with what is discussed in these podcasts.
