This Physical Culture Magazine ad from November, 1934 promotes the use of "Kelp-a-Malt" to help skinny girls get some lovely wobbly fat on their bodies. Eating Kelp-a-Malt will put five pounds on your bones in just one week! Why, it contains "more FOOD IODINE than 1600 lbs. of beef!" Link
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.
