USA Today article said that people who are on diets and write down everything they eat lose TWICE as much weight than those who don't keep a "food diary". This is according to a new research study (they said it is the "largest weight-loss study ever conducted").
I've never kept a food diary...have you? How do I even start, and keep up with it (I don't want to become overly concerned or obsessed with what I'm eating, either).
