WHO IS NUYU
NEWCASTLE?

We are passionate about giving people an introduction to the world of medical weight loss… We champion you and your goals in your way #youdoyou

We are people who have personally chalked up decades of experience with diets and diet culture, body shaming, body neutrality or even body positivity. We found our zen with our BMI only to be ambushed by perimenopause and menopause.

We have worked through it all. We found success for the kind of goals we wanted through medical weight loss and we want to share that with anyone who wants to know. We can talk for hours about this stuff. 

We can also just give you the information and you make your own decision when the time is right for you. 

That’s us in a nutshell. We champion you and your goals in your way
#you do you.
