Sara Sigmundsdottir’s nutrition coach talks Paleo myths and sustainable habits to optimise diet for performance goals
- Mike Molloy, who has a PhD in molecular and cellular biology, is part nutrition expert and part therapist for athletes using diet to be the fittest on earth
- The CrossFit community has moved on from an obsession with ‘caveman diet’ to embracing the benefits of carbohydrates for high intensity sport

Diet fads have “demonised” food groups for athletes and Dr Mike Molloy is working hard to correct misinformation for the world’s top CrossFit athletes.
“I could put out posts talking about the scientific approach, but all they need to do is hop on Instagram and find misinformation from influencers. Those people carry a lot of weight, so it’s easy to get carried away with trends,” Molloy said.
“The celery juice thing was my nightmare for about two months. And then it was the carnivore diet. Oh, man. These things pop up faster than I can swat them away. But it’s the way these things work, the flashy counter culture is attractive, but it’s got to be the slow right way.”
American Molloy, who has a PhD in molecular and cellular biology from Dartmouth College, has been working with CrossFit athletes for about five years. Three years ago, he set up his own company called M2 and now has a host of professionals nutritionists working with him to serve the community.
