Work With Me

Expert support, wherever you are with your GLP-1 medication.

Starting a medication like Mounjaro®, Wegovy® or Ozempic® is about much more than a weekly injection. It's learning to eat well on a smaller appetite, managing digestive side effects, protecting muscle while you lose fat, and building habits that hold up long after treatment ends.There are four ways to work with us, depending on where you are and how much support you want or need.

GLP-1 Meal Guide

Your free starting point
If you're not sure what to actually eat once the appetite drops, this is where to start. Five tips on what to prioritise from day one, plus a 2-week meal plan built to hit your protein, fibre and nutrition needs while you're eating in a deficit, not just a list of foods to avoid.

2. LEARN & WORK AT YOUR OWN PACE

The GLP-1 Success Academy

Self-paced support for wherever you are in treatment. A collection of courses, built around your current need rather than a single one-size-fits-all curriculum.
Courses include:
Starting GLP-1s - What to expect in the first weeks, how the medication changes appetite and digestion, and how to set your nutrition up properly from day one instead of catching up later.
Managing the symptoms - A practical course on nausea, constipation, reflux, bloating and food aversions, why each one happens and what actually helps.
Managing the plateau - For when weight loss slows and why more restriction isn't the answer. We explain what's actually going on, and what to do about it.
Preparing to come off GLP-1s - Building the habits, targets and maintenance plan that need to be in place before you stop, not after.

WHY MY APPROACH IS DIFFERENT


Plenty of people can tell you what to eat. Fewer can tell you why you're struggling to do it consistently and how to overcome your difficulties. I'm a Registered Dietitian with a background in Neuroscience and gut health, and a Postgraduate Certificate in Clinical Hypnosis, which means the plans I build don't stop at nutrition. They account for how your gut is behaving, what's realistic for your actual week, and the fact that knowing what to do and being able to do it consistently are two different problems. That's the belief every Third Sister programme is built on: lasting results come from supporting your body and your habits together, not food advice on its own.
