| Do we have to have just one cause for a disease like obesity? We know there are many factors that contribute to obesity. Alone or in combination, any of these factors may be contributing to obesity in any given individual. Certainly, 30% isnt enough to say that this is THE cause of obesity for everyone, but it sure is a lot of people where it may be a significant contributing factor. As for the causal relationship vs correlation, there is past data to support causation. If you infect animals with Ad-36 they gain weight, but any other adenovirus tested does not have that effect. |
