A lot of people feel unsure about what happens when they book an appointment with a dietitian, so I wanted to give a little insight into the process.

When you come to see me at 121 Dietitian, we start by talking through your symptoms, your medical history and your current diet. From there, I’ll work with you to create a personalised plan that’s realistic and tailored to your individual needs.

Whether you’re struggling with gut health issues such as IBS, ongoing digestive symptoms or simply want support improving your nutrition, my goal is always to help you better understand your body and feel more confident with food.

After spending 30 years working with people experiencing digestive issues, one thing remains consistent - there is no single solution that works for everyone.

Many gut health symptoms such as bloating, IBS or ongoing discomfort are influenced by a combination of diet, lifestyle, stress and individual health history.

Understanding those factors properly is the starting point for meaningful improvement.

Evidence-based nutrition support focuses on identifying the root causes of symptoms and building practical strategies that are sustainable in everyday life.

Gut health advice online can often feel overwhelming.

While trends come and go, research consistently highlights a few key habits that support digestive health long-term.

These include dietary diversity, balanced fibre intake, regular eating patterns and addressing lifestyle factors that influence the gut-brain connection.

Small, consistent changes tend to have the greatest impact over time.

If you’re struggling with ongoing digestive symptoms, personalised guidance can help identify the right approach for your individual needs.

I owe you an apology. This past year, I've been experimenting with AI tools and so-called solutions – and honestly? They've caused me more stress and disappointment. As a result, my communication has suffered because of it.

Here's what I've learnt: human knowledge is power. These bots aren't replacing me anytime soon.

Yes, blogs and real-life experience posts are time-consuming. Yes, sometimes it feels like no one's looking. But this year of change has shown me that authentic communication matters. It's what builds trust.

Our work here at 121 Dietitian continues to be full-on – and I wouldn't have it any other way. Every day brings great collaborations, and every consultation is about helping patients get unstuck from their unpleasant health journeys. We work together to change the route to a positive outcome with diet and lifestyle – ensuring what's good under the bonnet is reflected in what people see. That's why I show up. That's why we sweat the small stuff.

You never know what's round the corner, so I'm looking forward to next year and driving forward what matters: more hands-on communication and genuine connection.

Here's to human expertise. Here's to real relationships. Here's to what actually works.

What experiences do you have with the good and not-so-good of AI?
Is it just my business that has experienced this or has anyone else?
Any top ideas to share?
