Sport Is Unrelated To Obesity In Children
xiox writes "The UK government is planning to stop funding a study to understand obesity in children. The study fits children with accelerometers to measure how much energy each child uses in a day by moving. The results are surprising. Those children who do sports at school do not burn more calories than those who don't. Furthermore there is no correlation between body mass index and the number of calories used! The results are very interesting, suggesting that genetics and diet are the main reasons for childhood obesity, not sport. The UK government is trying to increase the amount of sport in schools."
Body fat isn't magic. It comes from food you eat. If you are exercising more and still have more weight, it means you are eating too much. People need to stop looking for excuses.
And yes, BMI sucks.
I used to bulls-eye womp-rats in my pants
While this may show interesting correlations, the fact remains that if more calories are burnt than are consumed, the body will lose weight.
When kids exercise more, they also eat more, and the body tries to retain the same reserves while burning off more calories. Eating no more, or just a little more, will be fine and the subject will still lose weight.
It's when the eating leads to significantly ore eating that there is a problem.
So, exercise and diet are required. But that isn't news. We've known this for quite some time.
Have you read my journal today?
And in reverse, lack of obesity doesn't mean you're healthy. You can be skinny all your life but still have high cholesterol and whatnot.
Actually, what the study found was that those who did sports were less active after school. So the non-sport doing kids did stuff outside of sports and thus burnt their share that way. So I assume those with good genes and diet were better off than those doing sports but but failed on the other parts.
The comment was well hidden deep inside the article... As usual.

There has been a lot of backlash over the growth hormones in meat and milk. It's why so many "organic" products are hitting the shelves. It does make a difference.
I just don't buy it that people's genetic makeup has changed that much in just a few decades that we are now turning out little fat farm children. It's too convenient of an excuse. Exercise and diet are two big factors that also govern obesity. As others pointed out, sedentary sweet-eating children become sedentary sweet-eating and fat teenagers and adults.
But a factor not so many know about are all the hormones injected into animals and added to their food so they get nice, fat, and juicy faster and on less food. Humans also respond to a lot of those hormones. Just the way the animals do.
Horseshit. When I was in school 20 or so years ago, you could count the number of fat kids (in a school of 2300 students) on your fingers, and a child who would be considered obese by today's standards was virtually unheard of. At my kids' schools, it's easier to count the kids who aren't fat than the ones who are, and there's at least one obese kid in any group larger than about ten.
I know it's all the rage to pretend that whatever problems our society causes itself don't actually exist, but this one is pretty easy to nail down. Anybody who says we don't have a serious problem with kids and their poor eating habits and lack of activity is either an idiot or a liar.
Being someone who works with an organization that promotes mass participation physical activities for children I can say that you have touched on a key issue. Physical activity with the pairing of the benefits of a healthy diet should be promoted and not the concept of sport that pits child against child and team against team. Sport is good but encouraging everyone to engage in a general healthy lifestyle which should include moderate to vigorous physical activity is key. And on a final note before I took up my job at this organization I was a "physical education" teacher (we prefer that over gym teacher, we are teaching a subject not a room) and I wasn't a frustrated former athlete and though there is a percentage of former athletes who become PE teachers, its not as high as you think.
End of line
Well children burn calories like mad even at rest. If for nothing else, they're always growing and that takes significant energy.
/. comments yet, I hope we do not damn the study simply because the results were not what we expected. That's the whole reason we're supposed to be doing studies in the first place. Rubber stamping desired outcomes is what corporate sponsored studies are for.

I know this will be blasphemy on this site, but Mountain Dew contains "brominated vegetable oil"
I'm not that afraid of bromine or vegetables. But a can of the stuff is 170 Calories. That's about 1/12th of what most people need in a day to not gain weight. 2 cans of the stuff, and an adult is well on its way to gaining a couple ounces that day.
But mostly I blame fruit juice for kid obesity. It's just as fattening as soda, which is hugely fattening, but somebody convinced parents it's good for you. 160 Calories per cup of a liquid (that barely satisfies any kind of hunger in most people) is not at all good for you. I was a fatty-fat as a kid, and my parents took me off soda and put me on juice. Not a lot of results from that one. I know a girl that is worried about her kid's weight but feeds him 100 Calorie juice boxes at every meal because it's healthy and won't grasp that the Vitamin C won't help him when he dies of a heart attack at 38. Switch that with water, your kid will lose a pound every 12 days. Absolutely guaranteed. Drop 1 juice box a day, and he'll lose a pound a month. Or at least gain a pound less. That stuff is evil.
Not that I think it should be illegal to sell the stuff or anything, but if the government spent a few of those research bucks on running commercials with graphs of how (Calorie input - Calorie output) / 3500 ALWAYS* equals weight change (get the guy from the Oxy-Clean commercials to yell the "ALWAYS" part), we'd be a lot better off. Of course, it would put all the many profitable, tax-paying voodoo diets out of business. Not that I think there's a conspiracy, I don't, but a lot of people would get mad if we were all skinny.
* Plus or minus a tiny, tiny bit that evens out to 0 over the long term and discounting (the very small) changes in metabolism resulting from lowered food intake. Metabolic conditions also (possibly) excepted. This part doesn't need to go in the commercial. This is just hear to discourage nitpicking on the obvious stuff.
People completely overestimate the effect of exercise on weight loss.
A grown man jogging (fast) burns around 100 kcal per 10 minutes. I'm assuming it's less for kids (because they're smaller).
Now compare this with the calories in a 65g Mars bar = 294 kcal.
Or in a Big Mac = 492kcal.
So let me sum it up: kids aren't fat because they're not getting exercise... they're fat because they eat CRAP all the time.
Yes, food is the problem. It is a problem in U.S. The best way to notice is to move there from a part of the world that still cooks their meals at home and don't have a McFatolds at any corner. I grew up in Eastern Europe. Growing up my mother prepared a large array of home foods, all kinds. I have always loved fruits (like apples and peaches) and vegetables and legumes (like tomatoes, garlic and beans). Everything was prepared at home by my mother from raw ingridients, we didn't even eat out because we couldn't afford it.
When I came to U.S. all my peers liked to eat hot dogs, hamburgers, pizza, mac and cheese and of course, fries. They all hated vegetables! I thought "how sad", the chain resturants have gotten these kids addicted to crap. Now I am married to an american and my wife still gets excited a lot more about pizza, fries and mac and cheese even though she rationally knows that grilled chicken with a light tomato sauce, or a salad with olive oil and vinegar is much better -- that doesn't matter. The emotional response for her is that "junk foods are somehow FUN!" and "veggies are BORING!".
Perception makes a huge difference. I see a pot of beans and I get excited -- "Woo, beans and toast!" she sees it and thinks "Yuk, but I guess I have to eat cause it's supposed to be better than a McFatburger".
My theory is that children here are just not exposed to good food. Just look at what babies and toddlers start eating here -- cerial, high carb, high fructose corn syrup + carbs kind of foods. Have you ever seen a "children's" menu in U.S.? -It is the "happy heart-attack by the time you are 30 in a shiny box" -- fries, corndogs, pizza and hamburgers. All these children grow up and do we really expect them to one day say "Hmm, I think I'll have some caviar or a grilled chicken breast with basil and olive oil?" No, they will still eat the same crap they grewu up eating. Everyone is obsessed about the calories they eat, I think they should be obsessing more about the quality of the food, not just pure calories.
In a nutshell:
TO ALL THE KIDS WHO SURVIVED THE 1930's 40's, 50's, 60's and 70's !!
First, we survived being born to mothers who smoked and/or drank while they were pregnant.
They took aspirin, ate blue cheese dressing, tuna from a can, and didn't get tested for diabetes.
Then after that trauma, we were put to sleep on our tummies in baby cribs covered with bright colored lead-based paints.
We had no childproof lids on medicine bottles, doors or cabinets and when we
rode our bikes, we had no helmets, not to mention, the risks we took hitchhiking.
As infants & children, we would ride in cars with no car seats, booster seats, seat belts or air bags.
Riding in the back of a pick up on a warm day was always a special treat.
We drank water from the garden hose and NOT from a bottle.
We shared one soft drink with four friends, from one bottle and
NO ONE actually died from this.
We ate cupcakes, white bread and real butter and drank koolade made with sugar, but we weren't overweight because,
WE WERE ALWAYS OUTSIDE PLAYING !
We would leave home in the morning and play all day, as long as we were back when the streetlights came on.
No one was able to reach us all day.
And we were O.K.
We would spend hours building our go-carts out of scraps and then ride down the hill, only to find out we forgot the brakes.
After running into the bushes a few times, we learned to solve the problem.
We did not have Playstations, Nintendo's, X-boxes, no video games at all, no 150 channels on cable, no video movies or DVD's, no surround-sound or CD's, no cell phones, no personal computers, no Internet or chat rooms.......
WE HAD FRIENDS and we went outside and found them!
We fell out of trees, got cut, broke bones and teeth
AND
there were no lawsuits from these accidents.
We ate worms and mud pies made from dirt, and the worms did not live in us forever.
We were given BB guns for our 10th birthdays, made up games with sticks and tennis balls and, although we were told it would happen, we did not put out very many eyes.
We rode bikes or walked to a friend's house and knocked on the door or rang the bell, or just walked in and talked to them!
Little League had tryouts and not everyone made the team. Those who didn't had to learn to deal with disappointment.
Imagine that!!
The idea of a parent bailing us out if we broke the law was unheard of.
They actually sided with the law!

While you're right that junk food packs on the calories faster than exercise can burn them, don't completely count out exercise. You don't just burn the calories during the exercise - it boosts your metabolism so that you're burning more calories all the time. Again, not to the point where you'll burn off a candy bar just by watching TV, but exercising AND cutting out excess junk will definitely result in more weight loss than cutting out the junk alone. It may only be a pound or two more a month, but over the course of a year that can make a big difference.
