At one time the gym seemed like the only place to seek any sort of “treatment” for obesity. Then medical equipment for physical therapy served as a guide to at least a few fitness equipment designers. Their fitness equipment slowly began to show up in the gyms of local fitness clubs.

Still, those who did not want to make regular trips to a gym looked for a different medical therapy. They hoped that scientists might discover yet another way to fight obesity. Some desperate dieters dreamed about seeing results from medical nutrition therapy. They pictured them selves pounds thinner, after using some new weight loss product.

Those who failed to find success with any of the available weight loss techniques—exercise, diet, and herbal remedies—often visited the office of a plastic surgeon. They agreed to undergo a liposuction.

While that surgical procedure has indeed helped a fair number of obese people to loose weight, it has also provided biomedical researchers with an important tool. It provided them with a source of fat tissue, tissue that could be cultured in the laboratory. That fat tissue has aided observation of one way by which a person might develop a larger number of fat cells.

Researchers at Louisiana State University have infected fat tissue with Adenovirus-36 (Ad-36). Doctors had linked Ad-36 to the obesity in animals, but they did not know how the virus created an environment that encouraged the storage of fat. The results coming from the Louisiana study offer some valuable clues.

The researchers in Louisiana found that stem cells in fat tissue infected with Ad-36 became fat cells. That transformation allowed those cells to store fat. In other words, someone infected with Ad-36 would grow more fat cells, and could thus become obese.

On the basis of these new findings, it would appear that scientists should be able to develop a vaccine against Ad-36. Theoretically, anyone who was given such a vaccine could then expect to live a life free of worries about unsightly obesity. For those already infected with Ad-36 there is, however, no easy way to remove unwanted fat cells.

Perhaps another group of researchers will attack that problem. It is difficult to anticipate what they might find. Is there a way to kill the virus? Does Ad-36 respond to ozone? Maybe obesity could be cured by some type of medical ozone therapy.

How can a person know whether or not he or she has been infected with Ad-36? Is there any diagnostic test for that virus? Laboratories already have a test for adenovirus, the virus known to cause respiratory problems. Could that test disclose whether or not an obese person carried Ad-36?

All of those questions have yet to be answered. The answers to those questions should help guide the direction of scientific progress in the battle against obesity. The answers to those questions should shine a light on the most promising pathway to take in the unknown region beyond liposuction—the region of new medical therapies.
