The gross story about him sharting in the White House soon after his gastric bypass has been in the news lately, but I found the rest of his story much more interesting--it sounds like after gaining weight post-bypass, Roker has gone Paleo or Primal, or something akin to it.

"He embarked on a 28-day detox during which he cut out caffeine, alcohol, sugar, dairy and gluten. By the end of the four weeks, he had lost 28 pounds. In addition, he altered his diet permanently: Today he eats only whole, unprocessed foods that are high in protein and low in carbs. And he embarked on a “slow method” workout regime that involves three 30-minute exercise sessions each week. Strength training creates more lean body mass, which in turn burns more calories, Snyderman explained."
