SYDNEY (Reuters) - Evolution and the environment, not just gluttony, has led to a global obesity pandemic, with an estimated 1.5 billion people overweight -- more than the number of undernourished people -- an obesity conference was told on Monday.
The mounting epidemic of obesity in children would see many die before their parents, said Kate Steinbeck, co-chair of the 10th International Congress on Obesity in Sydney.
McGill, senior lecturer in Population Health at the University of Auckland, said humans were designed to maximise their energy intake because their large brains used about one-quarter of their total energy expenditure.
"Early humans sought energy-dense food with high levels of fats, starches and sugars. We are genetically programmed to find foods with these qualities appealing," said McGill.
"However, highly energy-dense Western diets have had many of the flavour and micronutrients processed out of them. The artificial replacements in starchy, fatty and sugary foods make them over-palatable and easy to eat quickly."

He blew it! They were just about to blame it on "global warming" and he took it away from them.
Another example of Survival of the Fattest?
Excuses, excuses, excuses... We have no personal responsibility for our behavior.
Obesity pandemic? Does this mean Angelina will be visiting McDonalds taking away Happy meals for attention now?
"Get me everything on the menu, put it in a bucket and put eggs on top!"
Personal responsibility plays a large part, but i think the point thats trying to made here is that evolution has led to certain traits that encourage eating fatty and sugary foods. When I bite into a steak and say "mmmm" its not because i like the taste of the protein, but rather the fat. Early humans who were nomadic absolutely needed as much fat/sugar as they could get and thats a very plausable reason as to why we enjoy eating those particular things so much.
Ya, it's gluttony AND sloth.....
Over fed, over induldged, under exercised, no responsiblity, did I mention spoiled?
"Ugh! Look, Wog! There go energy-dense antelope with high levels of fats, starches and sugars! Ugh!"
I believe a big part of the problem is that kids do not get as much exercise as they did a generation ago.We had loads of junk food(candy,cokes,twinkies,etc..)available when i was a kid,but i don't remember obesity being a problem back then.As far as evolution is concerned,putting on weight(adipose)did assist in survival,especially in colder climates like Europe.Excess adipose was stored during times of plenty and the stores were used by the body during times of scarcity(winter,famine,etc).
You missed out with "it's Bush's fault".
It's Clinton that promoted and showcased fast food and followed up with fattening himself.
Just one big difference.
Clinton as part of the rich and wealthy was able to get the best surgeons for his heart and now the best shrinks to get him off snacking.
What a difference wealth makes.
Best one-liner I've seen so far on the thread.
A remarkably silly notion.
It seems fairly clear that obesity decreases one's reproductive fitness, even leaving aside the problem with early death due to heart attack or stroke: who wants to get it on with a lard tub?
If obesity is due to evolution there is nothing anyone can do about it. Have another burger and milk shake. Oh, and super size that.
Sure being fat helped. Until the predators started chasing.
"Grog no have to run faster than animal. Grog only have to run faster than you, fatso. Bye-bye."
We DO have the world's fattest poor people, right here in the good ol' U.S.A.!
Obesity is more a bodies reaction to bouts of bing eating with bouts of starving. The body turns off the "furnace" it uses to burn energy when it interprets periods of non-eating as meaning food stores are sparse. We've moved away from a foraging diet with increased technology, resulting in longer periods between meals and fewer of them. Humans use to have to forage for food all day long, and eat when they found food. The amounts eaten were generally small, but there were many meals each day. This is the most efficient means of burning fuel for energy the body needs to operate. Nothing, or very little was stored as excess. Today, most people eat mainly three meals a day, and usually over do it. This is especially true when eating out. The long periods between meals is interpreted as a food shortage, the body slows down metabolism, and food is stored as fat for later use. The huge amounts of sugar we now have in our daily staples doesn't help this process.
If one wants to lose weight go to eating five or six times a day, eating small amounts each meal, and increasing your exersize (weight training for three days each week, cardio for three days each week.) regiment. If you want to maintain, just change to the diet plan above (exersize is still important). Using this approach to my weekly regiment I lost between 50 and 60 lbs, and kept if off for more than three years.
Is that the royal "we" or do you have a tapeworm?
Diets actually cause obesity.
Does anyone know what company if Segway Inc. is publicly traded?
My father was a farmer/rancher. In his later years, he would laugh about how fat many of the younger farmers were. It wasn't the the younger farmers ate more or even different than their fathers had. It was a change in activity level.
Obesity Rise Spurs Call for Action
The latest statistics continue to show an increase in obesity among Americans. At last count, 31 states showed an increase in obesity compared to the last estimate. The data comes from an annual random sampling of adults via the telephone.
The trend toward a fatter America has been labeled a crisis by some and has inspired calls for dramatic reforms aimed at combating the problem. One organization promoting a healthier America is the Foundation Lobbying Against Bloat.
Marjorie Lass, chairman of the group says the government must take the lead. People cant be trusted to control their own appetites or work-off excess calories, said Lass. The choice must be taken out of their hands.
Lass suggested a number of reforms that his organization is pressing the government to mandate. These include the following:
1. Mandatory annual physical check-ups. Anyone found to be obese will be required to join a gym and attend daily fitness training classes. Those who fail to comply with this voluntary program will be sent to a boot camp run by ex-Marine drill sergeants.
2. Domestic food audits. Health Department officers will conduct random checks of refrigerators and pantries. Foods designated as insufficiently nutritional or containing excessive quantities of fat will be confiscated. If any of the residents are deemed obese they will be required to join a gym (see #1).
3. Change the building codes. Restaurants doors will be narrowed to 18 inches. Drive-thrus will be outlawed. Supermarket carts will be prohibited. All parking will be abolished.
Weve tried warnings and informational approaches, but people are still overeating, said Lass. Its time for some tough love.
Lass said his groups thinking has been influenced by the governments steps against tobacco use. Smoking used to be considered a personal choice, but people abused that choice by not making wise decisions, Lass observed. Its the same thing with obesity. People have been making unwise choices. We need to narrow the range so that only healthy choices are left.
Obesity epidemic is due to the fact that Food Tastes Good--It is plentiful--it is cheap
Was no obesity epidemic during the Great depression
"Sure being fat helped...."Yes it did.Not too long ago(few hundred years and longer)putting on weight could have made the difference between life and death and therefore by default,the ability to pass on ones genetics.
--Diets actually cause obesity.
I don't know..I put on a lot of weight when I quit smoking then went on a fat-free diet and lost 30-40 pounds and hace pretty much kept it off by watching what I eat. That's been at least ten years ago.
While much of this concern is justified, the statement above is alarmist horse $#!t that is unbecoming of a scientist. She is implying that obesity would take 25 years or more off an average lifespan, which is pure bunk. The average difference in life expectancy between obese and non-obese people is surprisingly little; 2 to 3 years at most. I suspect we won't even see a net dip in overall life expectancies, as gains elsewhere offset any effects from increased obesity.
