"I eat less for breakfast, but more for lunch."

Translation: Jem mniej na śniadanie, ale więcej na obiad.

[adherer]

Dinner is obiad, so I call lunch drugie śniadanie (second breakfast)

[Staruszek]

I'd agree with this but for some nationalities the meaning of dinner/lunch can be understood in different ways. When I'm in Poland then odiad is always the main meal of the day, usually around 3.30 P.M. and drugie śniadanie is before 11.00 A.M. normally. We'll have śniadanie very early as we'll be up to let the chickens out :-)
