About Mark J. Smith, PhD

Dr. Mark J. Smith graduated from Loughborough University of Technology, England, with a Bachelor of Science in PE & Sports Science and then obtained his teaching certificate in PE & Mathematics. As a top-level rugby player, he then moved to the United States and played for the Boston Rugby Club while searching the American college system for an opportunity to commence his Master’s degree.

He continued his studies in the Department of Physiology, where he obtained his Doctorate. His research focused on the prevention of atherosclerosis (the build up of plaque in arteries that leads to cardiovascular disease); in particular, using low-dose aspirin and antioxidant supplementation.

Christina Warinner “Debunking the Paleo Diet” Rebuttal

In May, 2013, I posted a response to the January, 2013 TED lecture by Christina Warinner in Norman, Oklahoma, titled “Debunking the Paleo Diet”. The website where my response was first posted is no longer in existence, consequently, because this lecture is often referenced, and has now had well over a million views, we feel it is worth re-posting my rebuttal here at   Christina Warinner’s “Debunking the Paleo Diet”, obscurantism at its very best. by Mark J. Smith, Ph.D. – May 12, 2013 (TED lecture link: After receiving a number of requests to comment on the TEDxOU

Posted in Featured, Paleo Diet Blog Articles, A New Look with a New Mission.

Very recently, Dr. Cordain reached out to me, his first Paleo graduate student, and Trevor Connor, his last Paleo graduate student, to help him launch a new vision and mission for his website; Today, we are excited to begin a new era, with a renewed vision and mission, that coincides with our recent new website launch. We have over a thousand articles about Paleolithic nutrition at the website and now you can easily find a specific topic by searching 32 blog categories. As time passes, new science can change previous held beliefs and; as has happened before, we will

I smell a rat, well actually prediabetic New Zealand Obese (NZO) mice.

In this month’s journal Nutrition & Diabetes, a paper titled “A low-carbohydrate high-fat diet increases weight gain and does not improve glucose tolerance, insulin secretion or β-cell mass in NZO mice” hit the headlines around the globe because of the University of Melbourne’s (home of the paper’s authors) publicity of the paper via an online article by Jane Gardner in Pursuit (   Of course the click-bait title of this article, “Paleo diets = weight gain”, is a little different from that of the journal paper in question.  In fact, if you download the PDF version of the study (

Get fitter this year in just 3½ minutes per week

So with the New Year upon us, diet and exercise resolutions typically feature prominently in many people’s lives.  However, in most cases, these resolutions fail fairly quickly and; in many cases, they have already been broken.  Despite the well-recognized beneficial impact of regular exercise on numerous health parameters, exercise participation and adherence in the general population remains poor1 – ‘lack of time’ being one of the most commonly cited reasons why individuals fail at committing to a regular exercise program2.  Consequently, it would be prudent to examine effective exercise programs that do not require a significant time commitment. Last year,

Over 25 Years of Eating Paleo And Counting

Some thoughts and considerations… Getting older has its merits; but, of course along with it, the typical thoughts that go along with the ever-accelerating passage of time. The latter are likely more positive when one is healthy, allowing for the enjoyment of the beneficial elements of aging and yet so many individuals suffer considerably with chronic disease as their years progress. And, it is not a stretch to say that the majority of these situations are preventable.  I turned 50 last year and I am extremely fortunate that I can say I feel little difference physically to when I was

Interval Training: Stop with the Tabatas and do some Gibalas!

Sprinting would obviously have been a necessary requirement for Paleolithic hunter-gatherers, both for the procurement of food and to avoid becoming food! Those who want to argue against that statement with the “persistence hunting” position, I will address that in a future post. Regardless, let’s fast forward to modern day and address a topic pertinent to my initial statement. To say that “Tabatas” have become an extremely popular interval training protocol in the fitness industry would be an understatement. When I wrote a position paper1 back in 2008 on the benefits of sprint interval training, the research conducted by Izumi
