According to the Twitter feed of cardiothoracic surgeon, author and TV host Mehmet Oz — @DrOz — couples are twice more likely to become obese once they marry. It's no easy feat to stave off the pudge in this world of fried beer, Double Down sandos and Starbucks Plenta-size Java Chip Frappuccinos. Take for example, Joe Cross and Phil Staples, the protagonists of the documentary Fat, Sick & Nearly Dead. Both suffer from vasculitis, an inflammation of the blood vessels. With hope, friendship and a whole lot of fruits and veggies, the two men embark on a weight-loss journey, with results that would make even Jillian Michaels melt. Tonight's one-time-only screening starts at 7 p.m. at Tivoli Cinemas (4050 Pennsylvania, 816-561-5222). Admission is $8.50. See tivolikc.com.
