Thinking about what you ate for lunch could keep you from bingeing on afternoon snacks. In a study, subjects were told they were taste-testing three different types of salted popcorn. They were encouraged to eat as much as they wanted. Interestingly, those who were first asked to recall exactly what they had eaten for lunch consumed 30 percent less popcorn than those who didn’t review their lunch menu beforehand. The researchers say that taking a few seconds to remember what you had during a recent meal might enhance awareness of how satiating the food was, which then might reduce future noshing.
