JARED FOGLE from Subway is only three months into his prison sentence for child pornography and having sex with a minor . . . and “In Touch Weekly” says he has already gained 30 pounds.  And it doesn’t sound like any of that is muscle. A prison source says, quote, “Jared’s breakfast is usually Frosted Flakes with fruit or oatmeal with cake.  He loves ‘cake day’ in the dining hall twice a week and he buys Honey Buns by the box, as well as other pastries, on his weekly shopping day. “He’s been known to eat an entire box of eight at one sitting!”
