A study conducted by Brian Wansink and his colleagues points out how mindlessly we can eat. Two groups were given different situations. One group had a normal bowl of soup that would empty out as they ate it. The other group had specially designed bowls that had a pump system built into the bottom that could add more soup to the bowl as the person ate (they were not aware of this). Everyone was told to stop eating when they were full. The people who had the bowls that kept refilling ate 73% more before reporting they were full than those who had the regular bowls of soup, supporting the assertion that we often use visual cues to figure out if we are full (clean plates), rather than our true feeling of fullness. As such, trying to fill our plates with the right amount of food, eating slowly and then giving our minds a chance to catch up with our stomachs is key.
