Pantries exist for a reason - be wary of what you leave out. As the Food & Brand Lab put it, "the farther you have to walk the less you eat." College secretaries were found to eat twice as many chocolate kisses (9 versus 4) when these kisses were placed on their desks than when they were placed 6 feet away. They were also more likely to lose track of how many they had eaten.
Same goes for any kind of snack. When foods are sitting out, people tend to "graze" and eat them more frequently.
