Episode 66: Nutrasystem keeps you feeling fuller (than what)

I started watching commericials and getting annoyed with the grammar earlier this year. One of the first commercials that got 'under my skin' was the Nutrasystem commercial with Terry Bradshaw saying "I ordered me" Nutrasystem.

You have probably seen another ad for Nutrasystem, this one with the mom walking out of the pool in her bikini. The voiceover for that spot says that "Nutrasystem  keeps you feeling fuller, longer." Fuller and longer than what?

Fuller and longer are comparative words. A better use of these comparative words would be:

• Nutrasystem keeps you feeling satisfied for long periods of time.
• Nutrasystem keeps you feeling fuller than a soup diet.
• Nutrasystem keeps you feeling fuller than a fast food lunch. Is any of this true? 

If Nutrasystem keeps you feeling satisfied better than a normal meal, or another weight loss meal program, then say so.
