    Obesity Caught Like Common Cold

    Yet another claim that a common and contagious virus is linked to some cases of obesity is in the news today.


    Studies on humans show that 33 per cent of obese adults had contracted an adenovirus called AD-36 at some point in their lives, according to an article in the UK's Daily Express, whereas only 11 per cent of lean men and women have had the virus.


    The research, to be presented in a BBC television special, is not big news to scientists, however. Further, some worry that the portrayal of obesity as something you simply catch could obscure the fact that overeating remains the biggest driver of obesity.


    The facts

    The National Centers for Disease Control and Prevention estimates that about one-third of U.S. adults are obese, as are 16 percent of children and adolescents age 2 to 19.


    Obesity increases the risk of heart disease, type 2 diabetes, stroke and other illnesses.


    It is increasingly clear, several experts say, that viruses might play a role in some obesity cases. There are 49 known human adenoviruses. They cause everything from the common cold to gastrointestinal problems and eye inflammation, pneumonia, croup, and bronchitis.


    AD-36 was first fingered as being possibly linked to obesity more than a decade ago. Nikhil Dhurandhar, of Pennington Biomedical Research Center in Louisiana, and a colleague made the connection in 1997 in research presented at an annual Experimental Biology meeting. That preliminary study of 199 people found that up to 15 percent of them carried antibodies to the virus, which provided indirect evidence that they once were exposed to the virus itself.


    Prior to that, Dhurandhar had showed that another type of adenovirus that infects birds and is found only in his native India could induce obesity when it was injected into chickens.


    In 2006, research led by Leah Whigham of the departments of Medicine and Nutritional Sciences at the University of Wisconsin, Madison found that another human adenovirus, AD-37, causes obesity in chickens. The results were published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology published by the American Physiological Society.


    Then in 2007, researchers found that AD-36 could transform adult stem cells obtained from fat tissue into fat cells. "We're not saying that a virus is the only cause of obesity, but this study provides stronger evidence that some obesity cases may involve viral infections," Magdalena Pasarica of Louisiana State University (and a colleague of Dhurandhar) said at the time.


    Today's claim

    Today, Dhurandhar said it's the spreading of the virus to other parts of the body that's key to its ability to fuel obesity. "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," he said in the Daily Express.


    Other researchers point out that the prime cause of obesity is still likely to be environmental, as in what you eat.


    "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," said Tony Barnett, professor of medicine at the University of Birmingham.


    And as if all this isn't confusing enough, a study earlier this month suggested that exercise, despite its many benefits, it not as important in avoiding obesity as is a better diet.

    Even more reason for me to stay out of Walmart. I don't want to catch any more fat germs than I already have. :tongue: Walmart seems to be their mecca in Georgia. They go their in lardalicious groups, daily to worship. Maybe that's why they have those anti-bacterial wipes for the shopping cart handles now! :eek: To prevent the spread of obesity. :cool:

    I have some news of my my own:

    BEING FAT IS LINKED TO OBESITY

    If you don't eat, you cannot possibly become obese or "fat". That's a bit extreme but even so, if you eat normally (three meals a day, limited to no snacking) and if you exercise maybe three times a week you will not become fat.

    People who eat normally and do not use food as a crutch or as a mood regulator will remain healthy. You don't even really have to exercise a lot providing that you choose and limit your food intake.

    The only evidence I have seen which is believable is that there is a gene that increases a person's appetite to the point where they do not know if they are "full" or not so they can and do eat more than the average person.

    Having said that, I am sure some CBT, self awareness, or common sense would change that habituated behaviour.

    You have to eat A LOT to become clinically obese. I would hope that somewhere along the way that sort of person would realise that they are extremely overeating. If they don't then to be honest I think it's their own fault.

    I have no sympathy for the 'Half Ton Son' and his mother.

    That sounds really scary actually. So you could be genetically thin to begin with, yet once you 'catch' this fat gene you could then be more liable to gain body fat more than what you were naturally dispositioned to beforehand. Scary.

    You wold think that with the super morbidly obese there would be a cut off point such as when you can't reach your ass to wipe yourself, but there isn't.

    There are many different things that contribute to why one person gains and another doesnt. Many of them have been mentioned here:

    1) High Calorie consumption- this can be tricky because many people while not eating what they think is a lot may be eating something that is highly caloric and filled with fats and sugars. Often things that are cheap and plentiful may fit this category. Simple carbs are major contributors.

    2) Lack of exercise- yes some of us have slowed down in our exercise. OR never participated. There are others for whom injury or arthritis,etc. have helped to slow or sideline them

    3) Slowed or slowing metabolism- Remember the old joke about it being someone's glands well for many women as they reach perimenopause their thyroid either goes kaput or at least slows down their metabolism. It has been found to be legion in the black community. Also medications can affect one's metabolism. Not to mention constant dieting.

    4) Medications- Medications that help to cure one thing may also cause inflammation and severe hunger in other cases.

    5) Stress- Cortisol the hormone that makes the spare tire belly is known to be exacerbated by stress. How many of us dont have that in our lives?

    6)Genetics- Yes, Virginia you can inherit bum genes that do not metabolize food as efficiently as others...

    7) Hormone imbalance- There are hormones within each of us that regulate all sorts of things in our bodies .Often when we have something out of whack our brain will often at the expense of weight seek those things that can help to recalibrate the imbalance. Dopamine imbalance makes one crave salty crunchy things, Seratonin- fatty sweets. This can bring even a strong man to his knees

    Let any one of these things happen to you and you are on your way. Most of us have multiple examples on this list. But we can try to get back to where we need to be though for some it may be a harder job than it is for others or even than it used to be...

    Nope, I have hyperinsulinemia, three times the insulin normal people have. As soon as I look at carbs I put on weight.

    There is research going on at the moment about how people can eat the same calories/do the same exercise, but have drastically different weights.

    Stop eating so much. Or eat less fast food. It really isn't that difficult!

    I think people would be surprised just how easy it is to alter the diet. Adding to what Gl3nn said, actually drinking those 8 glasses of water a day, cutting back on salt intake, and having fruit and veggies... it really makes a HUGE difference.

    I don't know if I agree with the idea of a germ you can catch that casues fat. I know certain meds can increase body mass, and I know that there is a genetic pre-disposition if you have fat parents you are more likely to gain mass. But, the idea of a germ/virus that makes you fat.... well, it's just silly.

    That's not really true. The pleasure response from the brain when eating can be addictive. It's not heroin or anything, but it's a little more complicated than just *not* doing something.

    A better cure is to exercise. Raises the metabolism, adds muscle that can burn any extra calories taken in, good for the lungs all that good stuff.

    Now, that first part isn't terribly fair, devron. Yes, there is a pleasure response from eating Mcdonalds and such but it isn't like they are FORCING the food down your throat. If you don't go, or choose the healthier options it helps....

    However, glenn's original point is true. Don't eat fast food 5 times a week and you won't become obese.

    Exercise is a good idea though, that is soemthign everyone can agree on.

    As Jeff said, they don't force the food down your throat.

    If you really want to eat, then eat something healthy. Try fruit for example. Or vegetables. You can eat as much as you want of those.

    Also... don't eat until you're totally full. Just eat until you're not hungry anymore. And... it's not because they offer a supersized menu, that you actually have to take that one. Take a smaller menu!


    Teach your kids to eat fruit and vegetables for god's sake. They're tasty and good for you. (Yes, I'm aware I sound like a commercial)

    Mem: You've touched upon subjects that have always been a source of wonder and amazement to me. First, just how do the 300 lb folks go to the bathroom without breaking a toilet seat? Second, yes, just how do they keep themselves clean? There has to be a point of unreachability with regard to toilet paper and all that body fat making the butt hole impossible to locate.

    North Americans are loathe to install bidets in their homes, which is unfortunate. I cannot imagine living without one. As I've stated umpteen times before in other posts, bidets are not the exclusive property of women. They are for the whole family. I'm certain a bidet would make it much easier for the obese to keep their hygeine quotient high.

    Maybe there's a ton of money to be made re-introducing the bidet to the obese American public, selling them door-to-door along with a free set of fudge-colored hand towels. :redface:

    I'm not talking about McD's food--people shouldn't eat that AT ALL. Food itself can become an addiction. I'm not talking about pleasure of taste, the brain releases chemicals activating the pleasure centers of the brain when you eat. Any food, not just fast food. That's one of the reasons people kicking other habits tend to put on some pounds.

    No, no one forces someone to eat and I'm not saying that it is something that can't be overcome, I was only saying that it's not really as simple as some think.

    From what I understand the point where you can not reach to clean yourself is at about 500 pounds. Less for women since they have a smaller frame. I heard a guy on the radio, after he lost weight, say that he had to have his girlfriend wipe his ass with towels.

    I saw a huge lady on Oprah once and she said that she had to jump into the shower after taking a dump to clean herself off. She also said that if she had to go somewhere far away and had no access to a shower that she would keep from eating. It's incredible how she can force herself not to eat at times, but could not find the will power to diet.
