Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(无可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

   Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies… and always get the smaller bag of popcorn.

   According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

   Nutritionists have gone back and forth about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and get over overeating.

   Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.
