Registered Dietitian • Functional Nutrition Specialist
For over a decade, I’ve helped clients restore their health by addressing the root causes of weight, hormone, and digestive imbalances.
My approach combines clinical nutrition, functional medicine principles, and personalized lifestyle strategies to create sustainable, long-term results — not temporary diets.
Today, I work with clients globally through my digital coaching platform, nFit Online Diet, supporting individuals who want to improve their metabolic health, hormonal balance, and overall quality of life.
My Approach
I believe nutrition is far more than calorie counting.
True health comes from understanding how the body’s systems work together — including hormones, digestion, metabolism, and stress response.
In my work, I focus on:
• Hormonal balance
• Gut health and microbiome support
• Metabolic flexibility
• Inflammation regulation
• Sustainable weight management
This integrative perspective allows me to identify the root causes of health challenges and create personalized strategies that work with your body — not against it.
Areas I Specialize In
My practice focuses on helping clients with:
✔ Sustainable Weight Loss & Weight Management
✔ Hormonal Health (PCOS, thyroid issues, insulin resistance, perimenopause & menopause)
✔ Digestive & Gastrointestinal Health
✔ Gut Health and Microbiome Support
My goal is simple:
To help you create lasting metabolic balance and a healthier relationship with food and your body.
International Education & Professional Background
I completed both my Bachelor’s and Master’s degrees in Nutrition and Dietetics at Hacettepe University, specializing in weight management and metabolic health.
Throughout my career I have:
• Founded nutrition departments in clinical and psychiatric hospital settings
• Worked in sports nutrition and private clinical practice

The nFit Online Diet System
In 2012, while living in the United States, I developed the nFit Online Diet System — one of the early digital nutrition coaching platforms in Turkey.
What began as a simple online program has evolved into a global nutrition platform supporting clients across multiple countries.
Since 2021, my entire practice has been fully online, allowing me to work with clients regardless of location.
Melbourne-Based, Globally Connected
I currently live in Melbourne, Australia, where I continue to provide personalized nutrition consulting worldwide.
Over the years, I have seen firsthand how the right nutritional strategy can transform not only physical health, but also energy, mental clarity, hormonal balance, and overall wellbeing.
