That study just confirms what has already been known for years by most people who aren't out to market you something. Maybe it will help to kill that useless prepared diet foods industry, Marie Osmond notwithstanding. It's still all about calories in versus calories out. It doesn't matter what the calories come in as far as weight loss goes, but of course, it does matter what foods you eat for other health reasons. So you can't just keep eating chips and soft drinks.
