Scientists find how obesity gene makes people fat

Scientists have figured out how the key gene tied to obesity makes people fat.
Since 2007, researchers have known that a gene called FTO was related to obesity, but they didn’t know how, and could not tie it to appetite or other known factors.
Now, experiments reveal that a faulty version of the gene causes energy from food to be stored as fat rather than burned. And genetic tinkering in mice and on human cells in the lab suggests this can be reversed.
