About

Who is Dr. Ludidi

Samefko Ludidi, Ph.D. (Dutch–South African, 1985), also known as Dr. Ludidi, is a renowned nutrition scientist, bestselling author, and private coach and consultant. He is a health & wellness expert with more than fifteen years of experience.

By focusing on natural approaches on how to get back in contact with our bodies to live healthier and happier lives, simply through food, movement, and lifestyle, Dr. Ludidi has become a thought leader in his field.

On his quest to unravel what’s best for our health, the Doc draws inspiration ranging from cutting-edge developments in western science to the traditions of communities that still live in the rhythm of their environment, and anthropological works. The Doc loves to rock his talks, and has been published internationally, nationally, and locally.

“That’s what I enjoy so much: breaking down the complexity of health and wellness.”

I love working with all kinds of people: athletes, top executives, busy parents, celebrities… they all share the same goal. They all want to live healthier lives, become more athletic, improve their performance, lose weight, calm their gut, and more. In my years of experience, it’s become totally clear that what people really want, above all, is to get a better grip on their lives. To make better decisions in order to reach their higher goals: a healthy body, and a calm mind. Satisfaction. Happiness in life. And not only to achieve this, but to maintain it as a natural lifestyle for the rest of their lives.

After I opened my practice in 2010, I noticed that not everything that I learnt in academia could directly be translated into what I called ‘the real world’. Because that world required a sense of human touch. Emotion. And that emotional factor, which is so important, was missing in the academic research I was studying.

I found that essential emotional factor through working with professional chefs. They made me aware of the fact that food is not just about nutrition and technical or scientific qualities. Food is also about an experience, taste, and social aspects. Food is feeling.

I wanted people to start questioning what we were doing and why we were doing it. We needed to get rid of the diet culture of minimizing our consumption of real foods. We needed to shift to eating more high quality, nutrient-dense, yet delicious foods.

Food can be made very complicated, through fancy names, research, and academic terms. But we mustn’t overcomplicate something that is so simple in essence. That’s what I enjoy so much: breaking down the complexity of health and wellness, and showing all the layers that are under the surface. Explaining them in a simple way that everyone can relate to. And making my advice sustainable so that it becomes a natural part of your daily life.

Over the past years, my interest in ancestral health and wisdom has skyrocketed. These essential and often overlooked anthropological aspects form the latest development to my view of health and my approach.

In the end, achieving health is actually about achieving happiness. And that relates to human beings of all kinds. Because in the end, we are all human. And so this is my story, but it is also the story of the people, of humanity, of all of us. It’s not just my story. It’s our story. All of us together.
