NuYu I Slender Wonder Medical Weight-Loss

Slender Wonder


Slender Wonder is a Medical Weight Loss Programme; which means that it can only be done through our network of accredited Slender Wonder Doctors. This is not a weight loss programme based on kilojoules, but rather a formula based on a low GI eating plan, our Slender Wonder products (shake and supplements), as well as a series of injections that helps to improve the body’s Leptin sensitivity.

  • Lose 5-8 kg’s p/month
  • No Muscle or normal fat, but only brown fat (adipose tissue) is broken down and supplied as food in the bloodstream.
  • This leads to stable blood sugar and great energy levels during the program.
  • No plato’s or yoyo effects afterwards
  • Great inch-loss and reshaping
  • Improved blood pressure & cholesterol levels within 2 weeks!

The owner of NuYu Slimming and Wellness, Sandra Fenner, is the daughter of late Dr. Jan Botha, founder of Slender Wonder, who developed the program over 45 years of research and practical application. At NuYu we strive to help each patient individualy to reach their goal.

Here are a list of what we offer at NuYu:

  • All medical and diet support by our overseeing doctor, Dr Mariska Oosthuizen.
  • Personal consultations and coaching during- and after the program as well as a full body analysis with our InBody120 machine. 
  • Meal support with a range of frozen low Gi meals made in our own kitchen. We sell the Slender Wonder Recipe books.
