Here's an article in the Washington Post that explains why WW doesn't consider fruit juice zero points. I've copied the pertinent paragraphs, including the name of the person at WW that the reporter was speaking with.
Even Karen Miller-Kovach, the chief scientific officer at Weight Watchers International, says the company's change on fruit didn't come easy, at least not with her at the scientific helm.
"I had to be assured six times over that it was the right thing to do" from a weight-management perspective, she says. What convinced her were clinical trials that showed people were not consuming too many extra calories when they could eat as much fruit as they wanted. (The program does not consider fruit juice, dried fruit or canned fruit to be "free" because of their high sugar content.)
