Marie Osmond (don't know her married name) keeps losing the same 50 pounds, has anyone else noticed that?

Every damned commercial she's in 500 times per day, she starts out saying she lost 50 lbs on NutriSlim or whatever the name is of the shit she endorses.  She's been losing that same friggin' 50 pounds for 5 years now!! 

It just seems very odd that she never loses even one pound more or gains a pound here and there.  Always "50 pounds"............  heh.          She needs to be standing on a scale while she makes these commercials, IMPHHO.
