CBS4 News presented the information on the "Fat Virus" named AD-36 as a potential cause or contributor to human obesity and the epidemic that we are seeing today. Reportedly the research done to date has shown that when rats were injected with this contagious virus, this caused the rats to gain weight. Fat cells seemed to increase in size and number. According a study done, 1 out of 3 obese patients test positive for this virus. And all affected are overweight and significantly heavier than those testing negative for the virus. But the most important point was stated: the treatment and what you can do about it, whether you have been exposed and infected with this virus or not, remains the same... a healthy diet and active lifestyle.
