This advertisement for "Allan's Anti-Fat" ran in the July 5, 1878 Daily Star (Marion, Ohio) and claims to "act upon the food in the stomach, preventing its being converted into fat."
While doing research for my blog, Paleo-Future, I often come across old newspapers, magazines and films that aren't paleo-futuristic but still catch my eye. This is the dumping ground for that material. Enjoy.
