It pays to be self-conscious, sometimes. This one-minute video from In59second's Richard Wiseman tells us that just looking at ourselves before we open the fridge can help us lose weight and make better food choices.
Wiseman cites a study by psychologist Brad Bushman, who found that people make healthier eating choices when they're in a room with a mirror. Seems like an easy way to develop healthier habits, when willpower alone isn't enough.
