Meet The Expert

What makes you an expert on The Paleo Diet?

In my early twenties, I came to appreciate why evolution by natural selection is probably the most powerful idea in biology. I have applied that framework to nutrition and clinical medicine ever since.

Describe the impact The Paleo Diet has had on your (and/or your family's) life?

Evolutionary biology has brought order to the chaotic world of nutrition, enabling me and my loved ones to successfully self-experiment with dietary changes.

What does “healthy living” mean to you? And what do you like to eat when you go to the movies? 

Healthy living means sharing simple day-to-day experiences with a clear mind and a pain-free body alongside the people you love. At the movies, it's a keto cheesecake!

What do you enjoy doing when you are not writing for The Paleo Diet? 

I try to spend as much time as I can in nature with those I love, as well as read lots of fascinating scientific studies that I haven’t had a chance to get to yet.
