Is fibre always good for your IBS?

Many believe more fibre is always better. But did you know that certain fibres can actually worsen gut symptoms for some people?

Every gut is unique. The right approach depends on your personal needs and symptoms. That’s why evidence-based, tailored advice makes all the difference.

Curious about what’s best for your gut? Book a personalised consultation with 121 Dietitian today. 😊

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?

Struggling with gut health for years?

Meet Sarah. She came to us feeling frustrated and overwhelmed by daily bloating and discomfort.

After a personalised assessment, we created a step-by-step plan tailored just for her. Blood tests were added to ensure we were optimising everything!

Included in her deep dive program:

* Gut balance
* Hormone balance
* Reduction of Inflammation
* Body recomposition
* Improve sleep
* Improve mood

Within weeks, Sarah noticed more energy, better sleep, and a happier gut, her waistline shrank from reducing the inflammation that was stopping her weight loss.

Her words: “I finally feel like myself again. I can't thank you enough Gillian!”

One week: sunshine and 25°C. This week: sideways rain, icy winds, and a dog who doesn’t care about either. 🌧️🔥
Back home drying my trainers by the fire and warming up with my healthy hot chocolate (recipe in my reels!). Sending warmth to anyone out in this today — and thinking of those who don’t have the comfort of getting home to heat.

Just back from 10 days completely offline in Marrakech, and I'm feeling the difference already.

Between consultations, building nutrition protocols, and running 121 Dietitian, I can easily slip into "always on" mode. But this trip reminded me why rest is actually a cornerstone of wellness – not a luxury.

Walking the medina, exploring the souks, riding a hot air balloon at sunrise, enjoying incredible food and staying hydrated in the Moroccan sun... it all recharged something I didn't realise I'd depleted.

Here's what I'm taking back: You can't give your best to your health journey (or your clients!) if you're running on empty. Rest, adventure, cultural immersion, good food, and genuine disconnection aren't distractions from wellness – they're essential parts of it.

If you're managing a chronic condition, working on weight loss, or building better habits, remember this: sustainable change includes rest days, joy, and moments that feed your soul.

Ready to support you all with renewed energy. 🌞

10 days. Zero work. Pure Marrakech magic. ✨

Just back from completely switching off – and honestly, it's exactly what I needed.

Between running 121 Dietitian, building personalised nutrition protocols, and supporting clients through their health journeys, I sometimes forget to practise what I preach about rest and recovery.

Here's what I learned:

✅ Wellness isn't just about what's on your plate
✅ It's about nourishing your mind and soul too
✅ Rest is productive, not lazy
✅ You can't pour from an empty cup

This trip was a masterclass in holistic health. Walking the medina, getting lost in the souks, riding a hot air balloon at sunrise, enjoying incredible food, and soaking up the Moroccan sunshine with plenty of fluids – that's the stuff that actually recharges you.

Whether you're managing your health, running a business, or juggling both – taking real breaks matters. Not scrolling breaks. Real ones.

Feeling refreshed and ready to support you all better. 🌞

What does a proper break look like for you?
