my guess and it's either
fatumnette need a "presentable" date/companion, not an
overweight one - or for pics
or
he's expecting to eat a lot (or drink a lot) during those
dinners and doesnt need the extra calories from the
burgers/fries
wedding dinners dun really have that much food leh, at least the
ones I've been to.
as for the presentable package part, a one or two month diet
will not really show any noticable improvement. I speak from
personal experience.
