Finally, a recent study showed more deaths among people who were obese for a greater part of their lifetime, Katz said.
"We should recall that obese people in their 70s now did not grow up in a world of epidemic obesity in childhood. Being obese over decades is very different than just gaining weight later in life," he said.
Because the new study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.
