About

Nutrition, the realistic way.

MN.Nutr, FOYHT-registered, fully insured. Working one-to-one with people across Ireland on gut health, metabolic health, and weight loss that lasts longer than the plan does.

My philosophy

The principles behind every plan.

Tailored to your week

Plans bend around your schedule, your budget, what's already in your fridge. You don't bend around the plan.

Evidence, not aesthetics

If the research isn't there, the recommendation isn't either. The Instagram graphic doesn't count.

Habits over rules

Small actions performed often beat rigid plans every time. We build the smallest set of changes that holds.

Built to last

A change that holds for a decade matters more than one that holds for a month. We optimise for the long game.

My story

I came to this the long way.

It started the way it does for a lot of women — years of trying what the magazines said, getting nowhere, and watching the people around me cycle through the same disappointments. The detoxes, the elimination plans, the supplement stacks promising the thing the next one would also fail to deliver.

What changed for me was learning to read the evidence myself, at Mac Nutrition Uni. The science is rarely as exciting as the marketing — and that's exactly why it works. It points to small, dull, repeatable things, done consistently, over a long enough timeline to matter.

That's the practice I built. Realistic plans, no shame, no fad cycles, no quietly selling you the next thing. Just food, your week, and someone in your corner who reads the research so you don't have to.

The best plan is the one you're still doing in six months — not the one that sounded clever in week one.

The approach

Joy is part of the plan.

My approach starts from a quiet, stubborn belief: food should be affordable, food should be nourishing, and food should still feel like food. Whatever your hormonal stage, your medical history, or how thin your week looks on paper, joy at the table is part of the work — not a reward for finishing it. These are the areas where I most often help people across Ireland strike that balance:

  • Gut health & digestion
  • Metabolic health & blood sugar
  • Sustainable weight loss
  • Pre- & perimenopause
  • Inflammation & autoimmune support
  • GLP-1 nutrition support

What I do
  • Read the research first.

    Recommendations point to a paper or a meta-analysis, not a vibe.

  • Look for root causes.

    Symptoms are signals — we trace them back rather than mute them.

  • Build around your real life.

    Your schedule, your fridge, your travel, your budget. The plan flexes.

  • Treat food as food.

    Meals you'd cook anyway, made to work harder. No protein-powder rituals required.

  • Stay in your corner.

    WhatsApp + email check-ins between sessions, so the week doesn't run away.

What I won't do
  • Hand you a 1,200-calorie sheet.

    Restriction without context doesn't hold, and you already know that.

  • Sell you a supplement stack.

    I don't take affiliate commissions. If a supplement makes sense, you'll know exactly why.

  • Demonise food groups.

    Carbs aren't the enemy. Neither is fat. Neither is dinner.

  • Push the body you saw on Instagram.

    Goals belong to you. My job is to help you reach them — not to choose them.

  • Disappear between sessions.

    You won't be left guessing what to do on Wednesday.

How we work

A hybrid practice. Three ways in.

Carlow consult rooms, the Castledermot clinic on Thursdays and Saturdays, or secure video — pick whichever fits the week you actually have.

Step one
Step 01 · free

Start with a free 15-min call

A short, no-pressure call to talk through what's been getting in the way. If we're the right fit, we go on. If we're not, you leave with a clearer picture either way.

Step two
Step 02 · in-person or online

Choose how we meet

Consult rooms in Carlow (Mon-Fri) and Castledermot (Thursday + Saturday) for in-person work. Secure video calls anywhere across Ireland for everyone else. Same care, same plan, your choice of room.

Step three
Step 03 · ongoing

Plans that move with your week

WhatsApp + email check-ins between sessions. A recipe book and shopping list tuned to your fridge. Reviews at four weeks so the plan keeps catching up to your life, not the other way around.
