Here's something fun to try if you get some free time one evening, and you want to consume about a month's worth of calories in an hour or so.  Got a spoon?

The competitive eater, Matt Stonie, baked up a huge chocolate chip cookie bowl and put a gallon of vanilla ice cream on top.  Watch the video to see if he can polish it off.

He weighs 11 pounds less than I do (he's 120), and he somehow packs away more calories than most girls do in three weeks.  Guys and their metabolism!  If indeed he actually digests all of that lactose.
