Christine Porter is hooked on the MyFitnessPal app. In October, after deciding to lose 50 pounds, Porter started typing in everything she eats, drinks and any exercise she gets.
"This is my main page here," says Porter. "It's telling me I have about 1,200 calories remaining for the day. When I want to record something I just click the 'add to diary' button. I'm on it all day either through my phone or through the computer."

It wasn't always so informal. In 2011, European Commission President Jose Manuel Barroso, French President Nicolas Sarkozy, President Obama and Japanese Prime Minister Naoto Kan walk together, in suits and ties, no less, after a meeting at the G-8 summit in Deauville, France.
