A group called "Sugar Information" ran ads in the late 60s and early 70s promoting soft drinks as a way to fill up and suppress your appetite. I suspect that people who followed this advice were disappointed -- the sugar crash from soft drinks is pretty widely believed to make you hungry, not full.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
