Dilan Bektaşoğlu, BSc (Hons)


Dilan completed her Bachelor’s degree in Nutrition and Dietetics at Acibadem University, Turkey. During the course she became increasing ly interested in the field and decided to continue her education by pursuing a two-year Master’s degree at the same university. She also worked as a graduate assistant during the first year of the MSc. Around that time, she has come to realise that the profession she has so aspired to join is not governed by rigid ethical standards and thus often does not benefit the clients. Because of this, she decided to move to London to pursue her career aspirations and to find work that is aligned with true ethical values of her profession. She joined CYK Nutrition in October 2019.


Dilan specializes in weight management and nutrition for chronic diseases. She is a member of the Nutrition Society and has been attending national and international conferences to stay up-to-date with the latest scientific proceedings.
