Online private dietitian clinic
Expert dietitian appointments tailored to your needs and preferences.
Personalised nutrition support that works for you
Our online private dietitian clinic provides one-to-one appointments with a Registered Dietitian for people across Ireland. Get personalised, evidence-based nutrition advice from home, tailored to your health, eating habits and everyday life.
Didi is due to take maternity leave from clinical appointments from November 2026. Registered Dietitian Catheryn Loach will be looking after the clinic appointments while Didi continues to manage the clinic and will return to seeing patients in 2027. Existing patients can continue their care with Catheryn without needing to start again.
What nutrition concerns can we help you with?
Weight management
Our dietitians provide supportive, non-judgemental nutrition advice for weight management, healthy eating and long-term health.
Rather than restrictive diets or one-size-fits-all plans, we can help you explore your eating patterns, health needs and goals and find realistic changes that fit your life.
Gut Health
Looking for a dietitian for IBS or digestive problems? We provide personalised nutrition support for IBS (including low FODMAP), constipation, diarrhoea, bloating, reflux, coeliac disease and other gut health concerns.
Your dietitian can help you explore how food and eating patterns may be affecting your symptoms and find practical changes that work for you.
Heart health and high cholesterol
A dietitian can help you make practical changes to what you eat to support your heart health.
We provide personalised nutrition advice for high cholesterol, high blood pressure and cardiovascular health, based around your individual health needs and the foods you enjoy.
Nutrition for neurological conditions
We provide dietitian support for people living with neurological conditions, including Parkinson’s disease, multiple sclerosis and other conditions that can affect appetite, eating, swallowing or nutrition.
Your nutrition advice will be tailored to your condition, symptoms and individual needs.
Healthy ageing and nutrition for older adults
Nutrition needs can change as we get older. A dietitian can support older adults with eating well, maintaining strength, poor appetite, unplanned weight loss and meeting changing nutrition needs.
We can also work with family members or carers where appropriate.
Poor appetite and unplanned weight loss
If you’re eating less than usual, have a poor appetite or are losing weight without meaning to, a dietitian can help.
We can help you find manageable ways to eat enough energy, protein and other nutrients while taking your health, appetite and food preferences into account.
Healthy eating and nutrition advice
Confused by conflicting nutrition advice? Our dietitians can help you understand what matters for your health and find realistic ways to eat well without needing a perfect diet.
Your advice will be personalised to your health, eating habits, lifestyle and goals.
Vegetarian, vegan and plant-based diets
Whether you’re vegetarian, vegan or simply want to eat more plant-based foods, a dietitian can help you make sure you’re getting the nutrition you need.
We can provide personalised advice on protein, iron, vitamin B12, calcium and other nutrients while helping you find an approach that works for you.
Intuitive eating and your relationship with food
Looking for support with intuitive eating or your relationship with food? We can help you explore hunger and fullness cues, eating habits and your feelings around food in a supportive, non-judgemental way.
The focus is on helping you develop an approach to eating that supports both your health and your relationship with food.
And more!
It is tough to make changes to our diet and lifestyle on your own.
Busy schedules, competing priorities and an overwhelming range of competing diets online.
You have obstacles to eating healthily that are UNIQUE to YOU.
No standard nutrition plan or diet has worked because it just didn’t fit into your life and didn’t understand your struggles.

Frequently Asked Questions
Your first appointment is a 60-minute online consultation.
Your dietitian will take time to understand your health, what you currently eat, any symptoms or concerns, your lifestyle and what you would like support with. Together, you’ll agree on practical next steps that are tailored to you.
After your appointment, you’ll receive a follow-up email summarising the main recommendations and any useful resources discussed.
Follow-up appointments are 30 minutes and give you time to review how things have been going since your first session.
You and your dietitian can discuss what has worked well, any changes in your symptoms or health, questions that have come up, and anything you have found difficult to put into practice. Your advice can then be adjusted to suit your needs and next steps.
You’ll receive an email afterwards with any updated recommendations or resources discussed during your appointment.
