That would depend on what the salad is replacing. Are they simply adding it to an existing meal? Then of course they won't lose.
Are they replacing a vegetable with a salad? Unless they had a large vegetable serving and a small salad, it will not aid weight loss.
Is the salad the entire meal? If so, I can't imagine how much they're putting on it that as a meal replacement it's still equal, unless they replaced already small meals with a large salad.

In many cases, portion size control is a better way than to try and totally change it up.
