Fitness & Health Blogger’s Conference
Dr. James Hill
One of Dr. Hill’s slides was a map of US obesity rates. In 2008 Colorado “weighed” in as the fittest state with an obesity prevalence of 15%-19%. A few days ago, new numbers were announced. In one article, Colorado was called the “skinniest” state with a new rate of 20.7%. I’m proud of Colorado (born and raised here), but calling us the skinniest state with an obesity rate of almost 21% is misleading. Our obesity rate has doubled since 1995. Dr. Hill suggested that Colorado is simply the caboose on a fast moving train going the wrong direction. We’re still the fittest state, but we’re gaining just like everyone else. The highest obesity rates in general are in adults over age 40, ranging from 36% to 42%. That’s a big segment of the population.
What do you think? Which is more important in causing weight gain—diet or inactivity?
Dr. Hill asked the audience that question and the responses were all over the place. It’s a complex issue and he encouraged lively debate. That’s the mark of a good teacher!
Our genes haven’t changed since the 50s and 60s, but our environment has. Our lifestyles are different. We don’t move as much as our parents and grandparents did and we don’t eat the same food they ate. Obesity is the adaptation to this new environment. Our ancestors ate whenever food was available and rested whenever they could. It was a biological necessity. Now, abundant, cheap, and poor-quality food is available at every turn and we don’t even have to get off our bums to prepare it, let alone find or catch it. We can pick up the phone (now conveniently unattached from the wall) and order it to be delivered. If we’re out and about, all we have to do is pull through a drive-up window and have someone toss a bag of food to us.
We have to motivate ourselves to move. Now it’s called exercise. It used to be the way we lived.
How many motivational sayings do you see posted on Facebook or Twitter each day? I’m “guilty” of that. I post upbeat, motivational ramblings on a regular basis. We sit on our bums in front of our computers and tell each other to get out and do something. It’s actually rather silly when you think about it.
As many of you know, I spent the past year co-writing a book with friend, colleague, and endurance athlete Pete Bronski of the blog No Gluten, No Problem
If you diet alone to lose weight, your metabolic rate will go down. That’s not good. Dr. Hill noted that one of the characteristics of people who were successful in losing weight and keeping it off was 60-90 minutes of exercise per day. And if you’re considerably overweight to begin with, you’ll have to work harder to lose the weight because of the metabolic difference between lean muscle and fat. It’s not easy and my heart goes out to people who have this challenge. Just losing my few pounds has been difficult. I can only imagine how overwhelming it would be to have 50, 60, or 100 pounds to lose. But it can be done. It takes lots of time (years maybe); an overall strategy of simple, small changes; a scale (horrors!); patience; good food; and lots of movement. LOTS of movement.
The point is to increase mitochondrial density, which will increase the ability to efficiently process fat. Although the biochemical process is complicated, the point is pretty straightforward. Increase muscle, decrease fat.
I’ll leave you with a definition of the mitochondria and we’ll launch into part 2 next week—Pursuing Metabolic Health: What we have Learned from Elite Endurance Athletes with Dr. Iñigo San Millán. Dr. San Millán is the director of the Exercise Physiology and Human Performance Lab
A double-membraned organelle that plays a central role in the production of ATP (energy-carrying molecule); known as the powerhouse of the cell. Mitochondria are small, spherical, rod-shaped, or filamentous structures that appear throughout the cytoplasm (material within a cell, excluding the nucleus). Mitochondria are self-replicative. Yay! They replicate in response to the increased cellular need for energy. Exercise causes an increase in mitochondria, which is a GOOD thing. We need to do that to lose weight and keep it off. FOREVER.
More on that in part 2.

Peace, love, and mitochondrial density!
