“I cannot thank Juliana enough for the nutrition, inspiration and changing my relationship with

I started my journey with her to improve my body composition and reduce body fat, but I got so much more! I got inspired to resume my running and have a challenging goal. I lost over 10% of body fat, I finally started seeing my abs, and I lost over 8kg without affecting my sweet cravings and occasional Friday night pizza.

She also introduced me to Masri, who helped me with my running performance. All training
backed up by science and years of experience.
I haven't got only a nutrition plan. I got a full athlete package and nutrition advice to improve
my sports performance. Couldn't be happier!”

“I struggled to find the right balance between my targets of reducing my body fat ratio, while maintaining sufficient energy to fuel and improve my cycling performance and went to Juliana for help.

Best decision ever made! 

Apart from having put together a nutrition plan to support both of my targets, she also took a holistic view on other key aspects of my life (impact of sleep, hormonal changes), which has helped me to gradually achieve all my targets.

I have learnt how to improve my diet in the long run now and cannot thank Juliana enough for her expertise and advice.

Juliana is a star and her passion for a healthy lifestyle and amazing athletic performance have greatly inspired me in trying to become a Superwoman myself. Very happy!”
