The Best "Science" Money Can Buy

Just when you think science has made a definitive statement, it seems like they switch it up on you. First, it's low-fats, then it's no fat, then it's some fats are good, then it's fats are okay, it's sugar that's the problem. Sometimes, these switch-ups are a natural progression of scientific inquiry; as more and better data becomes available, science will, as it must, change its consensus. Confusing for the rest of us, unfortunately, but, at least, it's the result of honest science.

And then there's the other kind. The kind of switch-up that's not made by scientists, and honesty has nothing to do with it. I'm speaking now about a new nonprofit organization called the Global Energy Balance Network, dedicated to creating "balance" in the way we think about diet, disease prevention, and exercise.

The group's vice president, Steven N. Blair, has this to say about its goals:

“Most of the focus in the popular media and in the scientific press is, ‘Oh, they’re eating too much, eating too much, eating too much’ — blaming fast food, blaming sugary drinks and so on, and there’s really virtually no compelling evidence that that, in fact, is the cause.” 

Uh … No compelling evidence? Doesn't he know that we know exactly how many calories are burned by exercising, and that the damage caused by bad food habits (heart disease, liver disease, etc.) can't be exercised away? Maybe not! Here's a tweet he made recently:





Don't get me wrong, I'm all for fitness, I'm all for exercise. But to claim it's more important than eating healthy is just plain mind-boggling in this day and age. Where did this Global Energy Balance Network and it's cockamamie ideas come from, anyway?

Maybe the following quotes from a piece in The New York Times can shed a little light on that:

"Coca-Cola, the world’s largest producer of sugary beverages, is backing a new “science-based” solution to the obesity crisis: To maintain a healthy weight, get more exercise and worry less about cutting calories … Coke has made a substantial investment in the new nonprofit [Global Energy Balance Network]. [Coke] had donated $1.5 million last year to start the organization … Since 2008, the company has also provided close to $4 million in funding for various projects to two of the organization’s founding members: Dr. Blair, a professor at the University of South Carolina whose research over the past 25 years has formed much of the basis of federal guidelines on physical activity, and Gregory A. Hand, dean of the West Virginia University School of Public Health."

So an organization supposedly dedicated to improving public health is, in fact, merely a prop, and the professors involved, merely puppets, for a soda giant.

Why the creepy clandestine approach, Coke?

"Health experts say [it is] part of an effort by Coke to deflect criticism about the role sugary drinks have played in the spread of obesity and Type 2 diabetes. They contend that the company is using the new group to convince the public that physical activity can offset a bad diet despite evidence that exercise has only minimal impact on weight compared with what people consume."

This sort of behavior by corporations is nothing new, of course. In marketing parlance, it's called having a "front" organization--that's right, just like the mob. Tobacco companies are probably the most notorious for the tactic, frequently using front organizations and doctors to advocate their arguments about tobacco use. One less-than-subtle example:

It'll be interesting, won't it, to see who comes out of the woodwork to parrot the Global Energy Balance Network's new fitness-over-diet mantra. When you see them, you'll know whose money is in their pocket, and whose best interest they really have at heart.

As for the rest of us, we should feel pretty proud of ourselves. We've been so good at avoiding their products that they've resorted to crazy puppet show theater to lure us back. 

Shame on you, Coca-Cola. Shame on you.

Walk it Off!

The benefits of exercise can't be overstated, though not for the reasons you might expect. Too often exercise, or lack thereof, is blamed for our obesity epidemic. "Those Americans, so fat--all they do is sit around all day!" or words to that effect. So, can exercise fix the problem?

Let's imagine we have just eaten a Snickers bar (remember, this is for science).

Okay, now let's imagine we are letting ourselves off the hook for this indulgence, because, after all, we are going to the gym later, aren't we? Let's take a look at our favorite calorie counting website CalorieKing.com to see just how much exercise it'll take to burn that sucker off:

That's right. It'll take you 69 minutes of walking, 29 minutes of jogging, 21 minutes of swimming or 38 minutes of riding a bike to make those Snickers calories disappear. That's a lot of time spent on exercise, isn't it? Are you sure you've got that kind of time, or anywhere close to that amount of physical endurance? A few more bad choices like that and you might as well start training for the Olympics, because that's what it'll take to work it off.

So, just like the only way to win "War Games" is to never play at all, the only way to "win" the calorie fight is to never put certain kinds of calories in your body in the first place--not trying to eliminate them with exercise after the fact.

However, I'm not suggesting not to exercise; far from it. We need physical movement to keep our organs functioning correctly, to keep our muscles limber, and to keep our bones strong. It's not just for our physical selves, though. Our mood, studies show, is also positively affected by exercise. 

This recent study shows that middle-aged women in Australia suffering from depression had their condition improved by regular sessions of exercise. It's a really good article, and an eye-opening study--so be sure to follow that link! An excerpt:
Women who averaged 150 minutes of moderate exercise (golf, tennis, aerobics classes, swimming, or line-dancing) or 200 minutes of walking every week had more energy, socialized more, felt better emotionally, and weren't as limited by their depression when researchers followed up after three years...They also had less pain and did better physically, although the psychological benefit was greater.
With depression so prevalent, "there is an urgent need" to identify treatments, including non-medical options that people can do themselves, said Kristiann Heesch, who led the study.
I'm willing to bet that those outcomes would be the same for anyone, not just depressed Aussie gals. So whether or not you belong to a gym, help yourself make it through these long, miserable winter months by finding someplace safe and warm to walk. Our local mall opens a few hours before their stores and many people take advantage of that to do a few circuits. Be sure to check and see if there's an option like that near you.

Okay, maybe not THAT mall...
