Look at the 5 Guys burger vs the McD's cheeseburger.    Compare the energy and sodium levels.

To eat the equivalent amount of food (so you're not hungry 20 minutes later) you'd have to eat 4 McD's cheeseburgers.

That is the only reason McD's scored that well, there's hardly any food there.   


Its a prime example of something where you need to look at the facts and make your own conclusion.    Not what the author or sponsor of the study wants to tell you.
