Dr. Andreas Eenfeldt is a Swedish medical doctor based in Karlstad who specialises in family medicine  He is primarily interested in how food and lifestyle can improve a patient's health and reduce their medication needs. 

In 2007, Dr. Eenfeldt started the blog “Kostdoktorn” – a Swedish word that means “Diet Doctor”. The goal was to make it simple for anyone to learn about low carb, high fat nutrition and discuss their results. It rapidly became the most popular health blog in Sweden and one of the most popular blogs in all categories.

In the spring of 2011 the English version of the Diet Doctor blog was launched. It was not immediately popular and for several years it mostly contained translated articles from the Swedish site. Slowly, things started to gather momentum. Income from book sales and frequent lecturing allowed Dr. Eenfeldt to gather a small team of co-workers and the website began to grow in popularity worldwide.

DietDoctor.com now has over 2 million visits per month and still receives no money from industry, offers no products for sale and contains no ads. It is funded entirely by paid subscribers with the goal of spreading the word about outdated nutritional information and to push for a food revolution.

“Reduce your carbs and increase your fat” is a long-held message behind low-carb nutrition. As Diet Doctor founder and CEO Dr. Andreas Eenfeldt explains, this has been his message since he started DietDoctor.com as a family physician in Sweden. 

But as Dr. Eenfeldt evolved, so did Diet Doctor. By reacting to evolving science and clinical experience, Diet Doctor began promoting the importance of protein and the role for “nutrient density,” “satiety per calorie,” and other concepts seemingly at odds with the simplistic message of increasing your fat intake. 

Here is Dr. Eenfeldt’s explanation of how this came to be as we discuss the past, present, and future of DietDoctor.com.

A bird’s eye view of the low-carb diet for metabolic disease, obesity, cancer, inflammatory disorders and dementia.

CEO Dr. Andreas Eenfeldt, with some inspiration from Dr. Ted Naiman, has led his team to help members tailor their nutritional guidance, to consider satiety and protein leverage for fat loss (if that is their goal).   

It was fun to chat with Andreas about his recent learnings, research and his n=1 experience.  We got to discuss a wide range of topics, including:

- Why did you decide to dive into a more protein-focused approach (rather than low carb or high fat)?  

- What did you experience as you have focused on a higher % protein diet?  How did your body composition and lab results change?   

- What surprised you the most from your recent research? 

- Why isn't protein leverage more central to our understanding of nutrition?  

- Why has there been so much confusion about low carb vs high fat vs adequate protein?

- What role do you see for nutrient leverage, as opposed to just protein leverage?  

- How can we dial in macros without swinging to extremes?

- How has the Diet Doctor community received the change in focus?

- Why is there so much confusion about the role of insulin?

- Are you concerned about 'excess protein'?  How much is too much?  How do people find the balance that is right for them?  

- Are you concerned about the role of protein activating mTOR, aging and cancer? 

- What are you most excited about for the future of nutrition?  

- Other than diet, what else do you do to manage your health?  

- Where do you see the keto movement heading in the future?
