Since 50 such viruses could be involved and all require further study, Whigham thinks a vaccine could take 5 to 10 years or more to develop.
In the meantime, she said, "I don't think washing hands will rid us of obesity. Other studies suggest that diet and exercise do make a difference, so there is no reason to think 'Oh my gosh, there is a virus, so I'm going to give up trying to stay in shape.'"
That's right, kids. Some scientists now think that even obesity may be caused by external pathogens. It's part of a growing movement in medicine that suggests that bacteria and viruses may be responsible for more of our ailments than was previously thought possible, and it's been gaining steam since Dr. Barry Marshall took home a Nobel prize for his demonstration that the H. Pylori bacterium caused up to 80% of all stomach ulcers. Dr. Marshall's findings were initially rejected by the scientific community, but study after study vindicated them, including one in which Marshall provoked an ulcer in himself by downing draught of the bacteria, then cured the same ulcer with antibiotics.
Despite cultural pressure to view obesity as a failing of character or lifestyle, Dr. Whigham has produced impressive evidence that certain virii related to pink eye may play a contributing role.
Tests on humans appear to support the animal studies. Obese people are much more likely to possess antibodies in their systems for one or more of these viruses, which suggests the people were infected with the viruses and that their immune systems were trying to fight off the bugs.
...studies on twins reveal that if one twin possesses antibodies for the fat-targeting adenoviruses, this individual tends to be heavier than his or her twin, even though both individuals have the same genetic makeup and often have similar lifestyle habits.
