Update: bunch of sessions in and she's still amazing you got to talk to her!
Lilian is very good at what she does. She is supportive and has so much knowledge. All the information she gives she does it with grace and from a place of genuine care. I was able to lose 30 lbs within months of her guidance. I never felt overly restricted with my diet and was able to make changes slowly based on her recommendations. Lilian also helped me manage PCOS with my nutrition and it has been significantly helpful. She is now helping me with my nutrition through pregnancy. It feels incredible having a nutritionist like Lilian on the sidelines coaching and cheering for you. I highly recommend her to anyone wanting to make practical nutrition changes to support a healthier and happier lifestyle. Thank you, Lilian!
