I would highly recommend this course...

Rebecca Thompson - personal trainer

I would highly recommend this course to anyone who is interested in learning more about Keto and how nutrition truly impacts the body.
Cliff delivers this course in such a way that is captivating and I enjoyed every minute of learning. I like that Cliff presents the research and evidence but also shows the other side of the equation. It is not all one sided and gives perspectives from all angles. I also found it invaluable to have direct access to Cliff through the Q & A sessions and being able to pick his brain on different aspects of the course. Getting reliable answers instantaneously from him as an expert was a huge bonus.
I am a massive advocate of Keto myself through my own personal journey, so I really enjoyed learning about it on a deeper level and understanding the underlying principles.
