Obesity is a major problem in Britain
OBESITY can be caught as easily as a common cold from other peoples coughs, sneezes and dirty hands, scientists will claim today.
Researchers believe that an airborne adenovirus germ could be causing the fat plague that is blighting Britain and other countries.
As many as one in three obese people may have become overweight after falling victim to the highly infectious cold-like virus, known as AD-36.
It is known to cause coughs, sore throats, diarrhoea and conjunctivitis but has now also been found to make fat cells multiply, leading to weight gain.
The shocking discovery will add to evidence that Britains obesity epidemic is not simply down to an unhealthy diet or lack of exercise.
Research suggests a third of UK adults will be grossly overweight within three years, with Britain even predicted to overtake the US as the most obese nation in the world.
The problem already causes 9,000 premature deaths in the UK a year and costs the NHS £1billion.
Many experts already believe that genes can make some people more susceptible to weight gain and now it seems that infections could also hold the key.
Studies have shown that chickens and mice infected with AD-36 put on weight quicker than uninfected animals, even when they were not given extra food. It has also been found to cause huge weight gain in monkeys.
Now studies on humans show that 33 per cent of obese adults had contracted AD-36 at some point in their lives, compared with only 11 per cent of lean men and women.
Professor Nikhil Dhurandhar, of Pennington Biomedical Research Centre in Louisiana, US, who led the research, said AD-36 continued to add weight gain long after those infected had seemingly recovered.
His studies indicated that the virus lingers for up to three months, during which time it multiplies fat and is contagious to others.
Dr Dhurandhar, who will make the extraordinary claims on BBC2s Horizon tonight, said: We now know that this virus goes to the lungs and spreads to various organs such as the liver, kidney, brain and fat tissue.
When it goes to fat tissue it replicates, making more copies of itself and in the process increases the number of new fat cells, which may explain why people get fat when they are infected with this virus. The findings were welcomed by some medical experts, although others sounded a note of caution.
Dr Shahrad Taheri, clinical director for obesity at the Birmingham Heartlands Hospital, said: Most people believe obesity is caused by environmental factors.
But there is a lot of information about how things like the furring up of arteries could be linked to infections. It is not beyond reason to think about various different factors, including infections, adding into the mix about what causes obesity.
Tony Barnett, professor of medicine at the University of Birmingham, said: These associations may give some clues but they detract from the basic message that we all need to take more exercise and eat a bit less.
This kind of research needs to go on but we have to be cautious.
Dr Colin Waine, chairman of the National Obesity Forum, said: We must acknowledge it is a contribution to the research but it doesnt alter the management of obesity.
The documentary also reveals research which claims to explain why those on diets feel permanently hungry, even when overweight.
A US study found that people have a natural body weight and respond to losing a few pounds in the same way as if they were starving.
The findings suggest that overweight people who diet will always suffer hunger pangs, even if they become lean and healthy.
Horizon: Why Are Thin People Not Fat? is on BBC2 at 9pm tonight.
Are Twinkies the carrier/host?
I know for a fact that smoking kills the cold-like virus.
The government should subsidize smoking.
Sitting in front of a TV snacking all day has nothing to do with weight gain.
Yeah its called Mcdonalds.
There’s some of that wishful thinking, it ain’t my fault science we have grown so fond of!!
Maybe not . . .
In 1985 I had cancer. The treatments made it damn hard to keep weight off. If I don't work out every day and watch me food intake, it is very easy to gain weight and living hell to burn it off. Atkins is just about the only thing that works.
A cold virus may be to blame for sudden, unexplained switches from a normal weight to packing on lbs. It's happened a few times with no clear reason. It would be nice to have a better handle on the mechanism and a means to control it.
It was all great fun when it was the yanks getting fat.
I don’t buy this for one second..
I’m curious - why are you hungry all the time? I’ve had weight issues off and on in my life, and most of them came from trying to follow a diet that didn’t suit me.
When I found a diet plan that did, I stopped having weight problems. I didn’t do well with a lot of the diet plans that are so popular - Atkins, South Beach, etc. do not suit me at all.
How did you decide on the diet plan that you follow?
I am absolutely certain my entire metabolism changed when I contracted pneumonia.
I have to deal with it, but no question, things changed.
It's possible that your pneumonia was initiated by a cold from the suspect virus. Mine started with flu that morphed into a secondary bacterial infection. It certainly messes with your lung capacity.
What do I have to smoke? My cold has me so miserable I'm ready to try anything.
Nah it’s all cause they eat too much - that’s the best and easiest way to become a fat b#stard and boy can the Brits eat and most of it they call ‘stodgy’ type food!
Good for you! I’ve never had 100 pounds to lose - I was once 40 pounds overweight, and it took me many months of different diet plans to figure out how to fix that. We’re all different, I think, in what we can eat. I can’t feel good on a very low fat diet - just adding a slice of whole fat cheese or a tablespoon of ultra rich ice cream to a meal makes a big difference to me. And if I’m hungry an hour after a meal, I eat something - carrot sticks or grapes usually. If your decaf satisfies, that’s the same thing.
But one thing I have to say - none of us should be “on a diet”. We should all have an eating plan that we will stay with for the rest of our lives. You’re not done until you know you will eat that way, happily, forever.
Now look-a here, if’n I believed this crap, I’d be sneezin like a Guinness contestant on all them skinny hoes, know whut Ahm sayin?
This is the 4th thread in 3 years to describe the tendency of the AD-36 virus to cause obesity. Click on the keyword, ad36, and find Coleus' thread.
Earlier this year, researchers in Dhurandhar's lab found that exposure to the virus actually caused adult human stem cells to turn into fat-storing cells.
Exactly. I think I caught that virus at Waffle House.
I was quite impressed by your recent post of the “Atkins” diet and Type II diabetes. It seems that they have truly found a “cure”.
Along these lines, I read with great interest “Good Calories, Bad Calories” by Gary Taube. The inescapable truth is that carbs, plain and simple, are the source of our problem, though HFCS is certainly a terrible food, as carbs go.
Looking for a magic bullet like the cold virus takes away the blame that we owe ourselves for the totally bankrupt nutritional advice that the government has served us for the past 50 years. Anybody who is interested in the history of suecessful weight loss should read the portions of the Taube book about “reducing diets.” These have been around for years, have always been successful, but fly in the face of conventional nutritional thinking.
I’ll take a pass on the adeno virus “cure”.
What about all those casseroles and homemade desserts that women keep leaving at your front door? Wonder if the virus is foodborne, as well?
Waffle House will do it every time, Slings and Arrows. LOL.
Wow. I remember my turning point too. Freshman in H.S. thin and then half way through my sophomore year I had appendicitis, emergency surgery, and fought my weight ever since.
That must explain the few extra pounds I’ve put on recently. And all this time I thought it was the ‘junk’ I’ve been eating more than normal this winter. Guess it’s not my fault, good! I’ll get some more Doritos at the store tomorrow, maybe some hoho’s too : )
3 months of swelling fat cells translates to a lifetime of obesity? Does it work retroactively? Sounds fishy to me.
The neighborhood cats must be eating them.
I like my hash browns Rachel Corrie style: Scattered, smothered, and covered.
To all those who have ever scorned a fat person and insisted that they must be fat just because they eat like a pig...well, in the immortal words of Sam Kinnison, “Bite me.”
Stay away from fat people, they are contagious !!!!!. ;0)
Is this serius?
mysterio: Yes. This is exactly correct.
Yes, and the reason is that going off a diet puts your eating habits back where they made you gain so much weight in the first place. The most important thing is to find a diet that you can live with forever and stick to it always. Low-fat, high-carb diets make many people hungrier than low-carb, but low-carb takes some getting used to. It's worth the effort though.
I think we’re all different. I do best on low fat, high carb diet, but I know other people who do better on low carbs.
It might take some experimenting to find out which is best, but it is worth the effort. It really only took me a few weeks with each plan to decide which was the best for me.
If obesity (at least in some cases) has a viral cause, would anti-viral strategies help? Or is it one of those things where it’s a viral hit-and-run, where the virus causes an effect that continues regardless of the continued presence/activation of the virus?
