Does Any of This Sound Familiar?

These concerns can have many contributing factors. Isabel looks beyond the symptom itself to understand the wider pattern and where nutritional support may be most useful.

You eat well, yet fatigue, poor concentration or energy crashes continue. 

You experience continuous bloating, reflux, irregular bowel habits or suspect food sensitivities. 

You’re preparing for pregnancy and want clear, evidence-informed nutrition guidance for preconception health. 

Your weight and waist measurements aren’t changing despite consistent efforts. 

Perimenopause or other hormonal changes have affected your energy, sleep, mood or metabolism. 

You feel overwhelmed by conflicting nutrition advice and tired of plans that don’t create lasting change. 

You live with persistent pain or inflammation and want to explore whether nutrition and lifestyle factors may be contributing 

You want a personalised and practical plan based on your complete health picture, not a generic meal plan. 

Good nutrition starts with understanding the person 


Many people looking for a nutritionist on the Northern Beaches need more than a list of foods to eat or to avoid. They want help understanding how digestion, hormones, metabolism, stress, and nervous system regulation may be interacting and which nutrition changes are most relevant to them. 


Isabel brings these factors together to create nutrition care that is evidence-informed, realistic and personalised to the individual.


“The aim is not to find the perfect diet. It is to understand what your body needs now and create a practical way of supporting it”

The Integrative Approach To nutrition

Why Nutrition Matters

Isabel draws from two distinct traditions: Western functional nutrition and Eastern food energetics. She integrates them with everything she observes clinically. 

Food Is Information For Your Body

Everything you eat provides signals that influence your metabolism, hormones, immune system and nervous system.When nutrition supports your body's unique needs, you often notice improvements that extend well beyond digestion or weight.

One Size Never Fits All Approach

No two people have the same nutritional requirements. Factors such as age, stress, hormones, sleep, activity levels and medical history all influence what your body needs. We can run a variety of tests to work out what supplements, foods and best herbs for you.

Looking Beyond Symptoms

Symptoms offer important clues, but rarely tell the whole story. Isabel considers your health history and all that you are experiencing currently, including your system's response to stress. Where appropriate, pathology and functional testing may also be recommended.

What Changes

What You Can
Realistically Expect

Results vary from person to person, but many clients begin to notice gradual improvements as their bodies receive the nutrients and support they need.

  • A comprehensive health and nutrition assessment
  • Review of existing blood tests and medications
  • Optional additional testing where appropriate
  • A personalised food and lifestyle strategy
  • Supplement recommendations only when inidcated 
  • Ongoing review and adjustment 

Changes you may notice

Better Energy

Many people experience improved energy levels and less reliance on caffeine throughout the day.

Improved Digestion

Reduced bloating, improved bowel function and greater digestive comfort are common outcomes.

Hormonal Balance

Nutrition can support healthy hormone function, helping improve mood, sleep and metabolic health.

Greater Confidence Around Food

Instead of feeling confused by conflicting advice, you'll understand what works best for your body and why.

Your Practitioner

Meet Isabel Peace

With more than 25 years of clinical experience, Isabel helps people understand why their health may not be improving, even when they are already trying to eat well. As a Northern Beaches nutritionist, psychotherapist and Chinese medicine practitioner, she looks beyond food alone to consider digestion, hormonal health, energy, sleep, stress, emotional wellbeing, health history and lifestyle.

Her training in clinical nutrition, Chinese medicine, acupuncture, EMDR, IFS and somatic and trance work allows her to bring the physical and emotional aspects of health together. This can be especially valuable when symptoms overlap, previous approaches have addressed only one part of the picture, or you feel unsure about what to try next.

Whether you are seeking support with digestive health, weight management, hormonal changes, low energy or inflammation, Isabel creates practical, personalised strategies that fit your life and can be adapted as your needs change.
