The Dietologist team, founded by leading reproductive health & fertility dietitian and nutritionist Stefanie Valakas, aims to support women and couples throughout their fertility and reproductive health journey.

Offering online consultations, self-guided programs and one-on-one tailored support, expert fertility dietitians Kaylee Slater and Stefanie Valakas help people wanting to conceive to upgrade their diets and lifestyles to improve their chances of conceiving and having a healthy baby. We support you along every step of this very special journey!

We help manage issues including endometriosis symptoms and pain, PCOS, hypothalamic amenorrhoea, thyroid conditions such as Hashimoto's, irritable bowel syndrome (IBS), early menopause and poor sperm quality in males, and support you throughout your fertility journey with evidence-based nutrition and diet advice.



Change isn't easy, but understanding why  we make certain diet and lifestyle changes to support your unique body and fertility can empower and motivate you to create lasting change. Beginning with a comprehensive nutrition assessment with an expert fertility dietitian and nutritionist, we'll develop the best strategy for you.


Now you've got the knowledge, it's time to take back the reigns and put the strategies we've developed into action! It can be tricky to get momentum, but this is the benefit of having a dietitian on your team - we will cheer you on, keep you accountable and equip you with all the skills you need to change your lifestyle and support your health and fertility.


This is where the transformation happens. Following education and empowerment comes the enhancement of your diet and lifestyle. These strategies are what makes a true impact on your fertility and chances of conceiving. Together, we continue to enhance through continuous "tweaks" to your plan to help you achieve the best results.
