It's great to be educated by someone who understands the theory behind nutrition, but it's even better to be educated by someone who has practical day-to-day experience with real clients. This is where theory and reality can meet in a balanced, but realistic manner!

What Our Students Have to Say

I have lost 7.5 kg since August 2023. It's not double digits yet, but the journey is something that I have to go through. Bernadine has been a lifesaver - pointing out how I must see myself as well as tips and tricks on how to do life and keep up a healthy lifestyle and lose weight. I love to eat, and I never thought that I would ever be able to fast for 24 hours, and now I have done two 36-hour fasts! My sugar craving has disappeared because I am satisfied with the food choices. Even during the difficult weeks, I am motivated to keep going. Thanks, Bernadine!

I have lost 18kg in 17 weeks. Initially, I felt hungry and tired, but as my body got used to the fasting, I found 24-hour fasting much more manageable. My sugar cravings have totally disappeared. I have attended a number of functions where I was not even tempted in the slightest. Yes, I firmly believe I can overcome my emotional eating, and I have conquered my emotional eating for the past 17 weeks. Seeing that I still have a long way to go, I know I can maintain this way of eating. I have gained a lot of knowledge and insight into my emotional eating cycles, the avoidance of insulin being secreted in order to prevent fat storage, etc.
