About me

Training Hard, Eating Well, and Still Stuck?

Hi I'm Alison, Metabolic Health Nutritionist for busy professionals 35+ who want more energy, mental clarity and sustainable weight loss. 

You've built a successful career. You train consistently and eat what you'd call "pretty healthy". Yet you're tired by mid-afternoon, the scales and the mirror haven't budged in months, and staying lean feels harder every year.

You're not lacking effort. Cutting calories or adding another workout hasn't worked because it doesn't address what's actually going on in your body. After 35, blood sugar patterns, stress responses, poor recovery and hormone shifts start to matter far more than they used to.

I know, because I lived it. I trained hard, ate "well" by every rule I knew, and still ran on empty. What changed wasn't pushing harder, but finally understanding why my body wasn't responding, and eating to support it instead of fighting it.

 I work with ambitious professionals who want more than another short-term diet. We look at what's really behind your plateau, using functional testing where it's useful, so you get answers rather than guesswork.

Together, we'll build a way of eating that fits your working life and helps you:

→ Lose stubborn fat and hold on to muscle
→ Have steady energy from morning to evening, without the 3pm crash
→ Think clearly and handle pressure without feeling frazzled
→ No calorie counting, no food rules you can't keep up, and no cutting out everything you enjoy.

Six months from now

You're not dragging yourself through the day. You're sharp in meetings, strong in the gym, and not thinking about food between meals. You're just eating well and getting on with your life, in a body that feels strong and capable, now and for decades to come.

Ready to find out what's holding you back?

Book a free 20-minute Clarity Call. We'll talk through what's going on and what you've already tried, and I'll share what I think is driving your plateau. You'll leave with clarity whether or not we work together. 

I take on a limited number of new clients each month so everyone gets proper one-to-one support.

Information about health conditions (*)

Nutritional therapy can help enhance the well-being of individuals diagnosed with serious medical conditions, but should not take the place of medical treatment and advice. If you have been diagnosed with - or suspect you may have - any of these conditions, please speak to your doctor before starting nutritional therapy or making any major changes to your diet or lifestyle.

Additional information

My initial Clarity Call is free and there's no obligation, it's simply a chance to talk through where you are and whether we're the right fit.

Where functional testing (such as GI-MAP, DUTCH, or blood panels) is recommended as part of your plan, this is priced separately and discussed with you before anything is booked, so there are no surprises.
