Two days ago, on October 23, I turned 40. For me, it feels different than every other birthday I have had: it feels like the marker of the transition between what can be considered young adulthood from 20 to 40, and middle adulthood from 40 to 70, which is then simply followed by old age. Maybe this is also linked to the fact that from the time I started competing, first in running track and field, then in road cycling, duathlon (running and cycling), off-road cycling and eventually in long distance running, I have always been in the normal, standard 18-40 category (like almost everyone else, I thought). And now, starting with my first race in the first level Seniors from 40 to 50 a couple of weekends ago in Bordeaux at the Ariane Cross 2012, I am definitely, and will be for the next 10 years, in the over 40 category. So, I have been reflecting a little on the past and the future: What is really important to me, what have I done and accomplished, what do I want to do in the future and how can I get there? Simple questions whose answers are not so simple.

In this context, I want to share two articles that completely changed my life, and completely changed my state of health, in some respects, rather suddenly, and in others, gradually over the years. Interestingly, I stumbled upon and read them both in the same week almost exactly five years ago. I won’t summarise, discuss their contents, nor describe the positive effects the simple but radical changes in dietary habits they prompted me to instil have had on me, on my wife Kristin and on our son Laurent. I simply encourage you to read them for yourself, and sincerely hope they will benefit you as much as they have us, and, I am sure, everyone who has ever read and applied the information they contain to their diet.

What is clear to me now much more than it has in the past, is that no matter what information we are presented, its impact depends entirely on how receptive we are to it. And this depends on all of what we know and think we know, on how we understand the connections between everything we have been exposed to, on our habits and tendencies, on previous experiences throughout our life, and very importantly, on the circumstances that form the context in which the information is brought to our attention. Thus, let me hope that these two articles come at a time that is ripe for you to appreciate their importance in regards to your own health, that of the people you care about, and everyone else for that matter.

The two articles are Insulin and Its Metabolic Effects by Ron Rosedale, MD (you can get the pdf here), and The Skinny on Fats by Mary Enig, PhD (get pdf here). After reading them, please consider sending this link to those you know who will or even possibly appreciate it. As you will see from the few case histories at the start of Rosedale’s presentation, the question of understanding and controlling insulin can really be a matter of life or death.
