We have known for some time that there are genetic factors linked to obesity. What we haven't known is if certain genes affect both a "baseline" 
body-mass index (BMI) and weight change.
Now, a new collaboration between scientists in the U.S., Finland, Denmark, and Italy has been released to answer these questions.
Sort of.
Over 10,000 Finns who were twins were interviewed at baseline and then 15 years later. The researchers investigated genetic factors influencing a person's baseline BMI and changes in BMI (usually weight gain) in adulthood. The scientists found little correlation between genetic factors for the twins' baseline BMI showing, for the first time, that the genes contributing to changes in BMI are probably different from those for baseline BMI value.

In other words--well, I don't know what the fuck this means either.
I think it means this: A lot of people are fat. The ones who weren't fat kids and become fat as adults? Well, we don't know if it is entirely genetic or if they are, like me, simply lazy fat-asses.
There.
Pass me a fat grant check. I could've told you all the same for far fewer euros.
