Do celebrities lie about their weight often?

Purely curiousity, because i was recently reading this article that revealed a lot of celebrities weights, and all of them seemed lighter than me, and i'm a lot smaller than them, not just bones but like height and obvious weight differences. And I know you all like to answer with "why do you care" or "get a life." But it's something that honestly sparked my interest and curiousity, so any answers would be appreciated. :)
