A teacher in Iowa, USA, went on a McDonald's-only diet a la Morgan Spurlock's 2004 film Supersize Me - and guess what? He actually lost weight!
Science teacher John Cisna, shockingly managed to consume the recommended 2,000 calories a day from carefully balanced food groups which all happened to be from Maccy D's. And even more surprisingly, he lost 37lbs!
After shifting the weight John came to a ridiculously profound yet totally logical conclusion: "It's our choices that make us fat. Not McDonald's," he told local television station KCCI.
Perhaps we should stop feeling guilty about those 20 chicken nuggets we deleted in the early hours of Saturday morning.
