Research Finds Inactivity Not the Cause of Childhood Obesity

3401730734 d4b3c2a87a 247x300 Research Finds Inactivity Not the Cause of Childhood ObesityWhich came first?  A lack of exercise, or the fat kid?  Obese children have long been painted as lazy, and it’s been assumed their inactivity - along with a poor diet – contributed to their size.  But ScienceDaily reported yesterday on a shocking new discovery published in the Archives of Disease in Childhood that avoiding exercise “has little if any role to play in the obesity epidemic among children.”

If you’re like most parents who are concerned for their kids’ health, you might be wondering what drove anyone to question the effectiveness of exercise in fighting fat.  Physical activity has clear benefits outside of weight loss, including promoting mental health.  Researchers at The EarlyBird Diabetes Study were concerned about findings from a 2009 study showing that “of all trials using physical activity to reduce childhood obesity, weight loss amount(ed) to just 90g (3oz) over three years.”  Gulp.  Nobody wants to work their butt off only to find out they haven’t worked any of their butt off.  That’s disheartening, to say the least.  Yet oddly encouraging to anyone who has “tried everything” but still struggled to lose weight.

So scientists at EarlyBird set out to prove that it’s not that “inactivity leads to fatness.  It could equally well be the other way round: that obesity leads to inactivity.”  They say “physical activity had no impact on weight change, but weight clearly led to less activity.”  Experts insist that the focus in fighting the obesity epidemic must shift from encouraging physical activity as a solution to changing what and how much children eat.  They’re not suggesting that exercise is unimportant, but that losing weight via healthy eating habits will enable children to enjoy their bodies more.

If you’ve always been a fit person, these results may boggle you.  But just as some people don’t need to work out to stay thin, others can work out all they want and never lose all of their fat.  I spent all of 2009 working out just so I’d be able to work out, and though I enjoyed it, it didn’t really work out.  I’m still roughly the same size I was last year, though my shape has changed a bit and I do feel better.  I’m glad this sort of Biggest Loser approach to weight loss has been debunked, though.  I’ve often wondered how many contestants on that show are fat again now that the cameras are gone.  My friend, comedian Poppi Kramer, won the Biggest Loser at home challenge a few years back, and she still works out for several hours a day in order to keep her gorgeous figure.  (Should anyone have to work out for 2 hours a day, 6 days a week?)  I’m not advocating obesity, which puts people at obvious risk to their health, but I do think it’s okay, as long as you’re healthy, to have a little more to love.

Lack of Exercise Not to Blame for Fat Kids? – The Stir (blog) | News 4 Diabetics commented on Jul 08 10 at 10:19 pm

It’s all in your perception. Our family of five is active for a couple of hours a day. I think that’s normal, not excessive. It’s swim team season and the team my kids are on has 125 kids. All different ages, body types, races, and genders. None of them are fat. Go figure.

I’m a guy who works out daily and regardless of how hard I work out I don’t really see much weight loss, I see improvements in my strength, endurance and energy levels, but my weight remains firmly in the mid 160′s, about 15 pounds overweight, glad to finally see that its not just because I’m not trying hard enough.

I work out a lot. A LOT. 7+ hours a week of running/elliptical and additional weight training and yoga (which I don’t count in my weekly tally). Some months I up my exercise schedule and others I just can’t manage it, but my weight really doesn’t fluctuate. The thing which does cause weight loss, for me, is keeping a food journal. It always amazes me how much mindless eating I do, eating I which I don’t do when I know I will have to write it down, which is minor (some samples at Trader Joes, a small cookie) but adds to my daily consumption. So while I encourage everyone to exercise, I am not surprised to hear it is not as effective for weight loss as some believe.

I’m trying to figure out how a 165 lb. MAN could possibly be 15 lbs. over-weight. Is he only 5 feet tall or something?

Would love to get a better understanding of what is causing childhood obesity. It seems like it’s more of a complex interaction of factors: poor corporation-produced food full of fat, sugar and chemicals; sedentary society where not moving is the norm; too much screen time for all of us; removal of recess and terrible quality of school lunches…??? How does a parent try to mitigate all of this?

There is some new evidence that it is a lack of enough sleep that may be contributing to childhood obesity. I learned about this in the book _Nurtureshock_, and here is a link to an article. http://nymag.com/news/features/38951/index3.html Of course, these research studies are based on statistics over a large population – there will always be individual exceptions.

I’ve never really had a problem with weight until this pregnancy but now can’t gain enough to please my dr. I agree about just eating better but was told by my dr to eat things that I know for a fact are horrible for you. I think people put too much into your weight and not your life style. I think your article is wonderful and thank you for sharing that. Especially since it works for both ends of the spectrum :)
