I know the study isn't anything to get excited about, but preventing weight gain is itself a worthy goal. It's so easy for the weight to creep up on you.
If it's a significant amount less or "ungained" weight, then absolutely - I know the creeping weight well. But in this case, any semi-decent dump is going to outweigh the whole thing. It's the kind of weight difference you'd shrug off in one day, let alone over 1400+ days.
