YOUR HEALTH. YOUR PRIME.
Most people think they need:
More training/ exercise
Less food
More willpower
Whats actually going on:
A metabolism slowed by years of under-eating
Nutrition that lacks structure, not just calories
Sleep, stress and hormones working against you
Inflammation and gut issues nobody checked
I Don’t Just Count Calories — I Fix What’s Holding You Back
I look at:
Nutrition quality and structure
Metabolism and energy balance
Reducing inflammation/ gut protocols
Training and exercise intensity
Sleep and recovery
Stress and lifestyle
Hormonal influences
Because fat loss and muscle gain don’t happen in isolation.
On a GLP 1?. Your Nutrition matters more , not less.
Weight loss medications reduce appetite — but without the right nutrition, you lose muscle, energy and metabolic health along with the fat. I help women on Ozempic, Mounjaro and other GLP-1s eat to protect what matters.
MY FOCUS
FUNCTIONAL HEALTH COACHING
For women dealing with fatigue, inflammation, gut issues or hormonal shifts — and no clear answers. I interpret your blood work at functional (not just "normal") levels, identify what's driving your symptoms, and build a nutrition and lifestyle plan to fix it. Your body won't change if your health is off — this is where we start.
GLP-1 NUTRITION SUPPORT
For women on Ozempic, Mounjaro or other GLP-1s who want to lose fat without losing muscle and energy. Weight loss should protect your muscle and metabolism — not just reduce your appetite. I structure your nutrition so the weight you lose is fat, your energy stays up, and your hair stays on your head.
SPORTS NUTRITION
For athletes and competitors — Hyrox, bodybuilding, endurance, team sport, weight-class events. I calculate your fuelling for training, competition and recovery days so you perform at your best and recover faster. Built by a world champion bodybuilder who's done it herself.
LONGEVITY/ WELLNESS
For women who want to feel strong, energised and vital as they age — not just avoid disease. Sustainable nutrition habits, targeted supplementation where it's needed, and a prevention-first approach to long-term health. This is about building a body you want to live in for the next 30 years.

Hi, I’m Melissa,
I've spent my whole life in performance — national gymnast at 16, marathon runner in my 20s, yoga teacher in my 30s, and world champion bodybuilder in my 50s. I've lived the science I coach.
As a Nutritionist and Functional Health Coach, I work with women who want more than a meal plan. I interpret blood work, rebuild nutrition from the ground up, and build training programmes that match — because the women I work with don't just want to look different. They want to feel strong, energised and in control of their health again.
I work in-clinic at South Eastern Active Health and Flawless Rejuvenation (Hampton and Toorak) and consult online across Australia.

YOUR QUESTIONS, ANSWERED
-
A nutrition consultation is a one-on-one session to assess your current eating habits, health status, goals, and lifestyle.
I will gather information on medical history, medications, bloodwork (if available), dietary patterns, food preferences, allergies/intolerances, sleep, stress, activity levels, and daily routine.
The session identifies barriers and opportunities for change, clarifies realistic goals (weight, body composition, performance, energy, digestion, hormones, chronic disease management), and prioritises what to address first.
Evidence-based guidance is provided: personalised meal planning principles, portion guidance, timing, food choices, and behaviour-change strategies (habit formation, mindful eating, planning, tracking).
Recommendations may include macronutrient targets, sample meals/snacks, supplement advice when appropriate
Follow-up structure is outlined: session frequency, progress tracking, adjustments, and accountability methods.
Outcomes: improved nutrition knowledge, practical strategies tailored to your life, sustainable changes to support health, performance, and wellbeing.
Who benefits most
Women seeking to prioritise health, manage weight, optimise performance, support hormonal health, improve energy, or navigate midlife transitions.
What to prepare for a consultation
Recent food diary or photographic log (2-3 days), list of medications/supplements, recent bloodwork, and a summary of goals and main challenges.
Be ready to discuss daily routines, cooking habits, and typical portions — honesty helps create realistic plans.
What to expect after
A tailored nutrition plan and practical strategies, measurable short-term goals, and a schedule for follow-ups to monitor progress and refine recommendations.
Education and tools to build lasting habits so you can feel stronger, more energetic, and in control of your health

Prime Fit Nutrition provides combined evidence-based nutrition and strength-training guidance tailored to women who want to look, feel and perform their best. While dietitians specialise in medical nutrition therapy and clinical dietary management, our service blends nutrition coaching with practical resistance training programming and lifestyle support to optimise body composition, strength and function.
Goal emphasis: Dietitians often prioritise treating medical conditions (diabetes, chronic gastrointestinal disorders, disordered eating, etc.) and clinical nutrition needs. Our approach centres on performance, strength, energy, and sustainable body-composition goals—helping you get stronger, regain confidence and improve day-to-day functionality alongside better nutrition.
Practical coaching and behaviour change: We focus on long-term habit formation, meal structuring for training days, and realistic, manageable changes that fit your life.
Dietitians provide essential clinical guidance and specialised assessments; our coaching prioritises implementation, accountability and progressive adjustments for performance outcomes.

Melissa works with women who are ready to take a proactive, invested approach to their health — whether you are navigating hormonal changes, GLP 1 Nutritional issues, struggling with energy and body composition, looking to enhance your aesthetic treatment results from the inside out, or simply wanting to build a sustainable relationship with food and nutrition that actually fits your life. If you have been going around in circles with your health goals and feel like something is missing from your current approach, nutrition coaching is likely the missing piece.

Item dA functional health nutritionist looks beyond calories. Melissa at Prime Fit Nutrition interprets blood work at optimal (not just “normal”) ranges, assesses energy, gut health, inflammation and hormonal markers, and builds a nutrition and lifestyle strategy around what’s actually driving your symptoms. She works alongside your GP, referring on when medical follow-up is needed.
-
Yes — this is an area Melissa is particularly passionate about. GLP-1 medications are a powerful tool but they work best when combined with expert nutritional guidance. Melissa works closely with women on GLP-1 medications to ensure that weight loss protects muscle mass and metabolic health rather than simply reducing appetite — because how you lose weight matters just as much as the fact that you are losing it. If you are currently taking or considering a GLP-1 medication, a nutrition consultation is one of the most valuable investments you can make in your outcome.
-
Every client is different, but most women notice meaningful improvements in their energy, digestion and general wellbeing within the first two to three weeks of working together — often before visible physical changes occur. Sustainable body composition results typically become apparent from weeks four to six onwards. Melissa sets realistic expectations from day one and tracks your progress carefully so your plan evolves as you do.
-
Yes. Most women who aren’t seeing results are actually under-eating, which slows metabolism over time. At Prime Fit Nutrition, Melissa rebuilds nutrition structure — the right foods, in the right amounts, at the right times — so your body has a reason to change. Clients typically see measurable body composition shifts within 8–12 weeks without restrictive dieting.
-
This depends on your goals and where you are in your journey. Most clients begin with fortnightly appointments to establish their plan and build momentum, transitioning to monthly check-ins as they gain confidence and consistency. Melissa will recommend a schedule that suits your goals and lifestyle — there is no rigid formula, just what works best for you. Appointments can be in person (Melb inner south) or online (Australia wide)

Melissa Hernadi, owner of of Prime Fit Nutrition is a Melbourne-based Nutritionist and functional health coach who works with women navigating body composition changes, perimenopause, fatigue and metabolic shifts. Her approach combines personalised nutrition, blood work interpretation and training programming — not just meal plans. Consultations available in Melbourne’s Bayside area and online Australia-wide.
-
Eating “healthy” and eating right for your body are different things. Common causes of persistent fatigue include under-eating protein, poor meal timing, disrupted sleep, stress, iron or thyroid markers sitting in suboptimal ranges, and gut issues affecting nutrient absorption. Prime Fit Nutrition assesses the full picture — including blood work — and builds a plan that targets the actual cause. A free 15-minute discovery call is the starting point.
