About Authority Nutrition

Welcome to AuthorityNutrition.com – a site that helps people make informed decisions about their health based on the best scientific evidence available.

Kris Gunnars

My name is Kris Gunnars. I’m a medical student, personal trainer and someone who has spent years reading books, blogs and research studies on health and nutrition.

My Passion for Nutrition

I became pretty much obsessed with health some time in the year 2007.

I started lifting weights, consuming every piece of information I could find on diet and exercise.

Fairly quickly, my main interest turned to nutrition. My goal in the beginning was to find out how to optimize physical health, mental well being and brain power.

I started reading books and searching scientific studies. Something I ran into which surprised me greatly was that the official nutrition recommendations I had been led to believe were wrong.

There is an immense amount of evidence I’ve found that runs completely contradictory to what the governments and dietitians around the world are recommending.

Since I started medical school and became a personal trainer, I’ve learned that the textbooks on nutrition that our future doctors and health authorities read are based on that same faulty or nonexistent evidence.

The fact of the matter is that there is an immense amount of incompetence in the areas of nutrition, weight loss and disease prevention. My goal is to change that and this website is part of my mission.

If you want to help, I encourage you to subscribe to free updates from this site or follow me on your favorite form of social media, then help spread the word.








Some personal stuff if you’re interested: I’m 28, born and raised in Reykjavik, Iceland and currently study medicine at the University of Iceland. In my spare time, I like to read, watch movies, work out and hang out with family and friends.

Why Authority Nutrition?

If you’ve spent any amount of time looking for health information online, then you’ve probably realized that the advice is conflicting and that no one seems to agree on anything.

All of the gurus have a product to sell and most opinions are more about belief and personal experience than facts.

The main goal of this site is to search the scientific literature for true answers, preferably from randomized controlled trials which are the gold standard of research.

Then the scientific jargon is deciphered to make it understandable by professionals and laypeople alike. Every effort is made to be objective, unbiased, honest and to present both sides of the argument.

If you’re interested in the truth about nutrition, then you are in the right place!
