>>You're assuming that "all" refers to people.
"Lets all" leaves few alternatives unless you postulate aliens who bought tickets to watch the earth being created. But google "alien" to confirm that they're skinny creatures unlikely to want to shed weight, so that would be silly (though googling "fat alien" is an eye-opener.)
>Answer 4: No I am not being a contrarian today. ;-)
>Why stop today?
One cannot stop without starting, grasshopper.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
