Brief summary: The purpose of the study is to investigate the effect of watching a television show with healthy food commercials, unhealthy food commercials, or neutral commercials on the consumption of healthy snack foods or unhealthy snack foods. There are three hypotheses: 1) Women exposed to a television show with commercials imbedded advertising food will consume more food than women exposed to a television show with non-food related commercials.

2) Women will consume more food when exposed to a television show with commercials advertising "unhealthy" food as compared to a television show with commercials advertising "healthy" food.

3) Women will consume the most food when exposed to a television show with "unhealthy" food commercials and have "unhealthy" snack foods available to consume.

Detailed description: The objective of this investigation is to investigate the effect of television shows with commercials perceived as advertising healthy foods and television shows with commercials perceived as advertising unhealthy foods on the intake of either perceived healthy snack foods or perceived unhealthy snack foods in normal weight, dietary restrained females.

Forty-eight women will participate in this study and will be randomized to one of six conditions where they will be exposed to a 30-minute television show (Saturday Night Live) during which they will be given two different pre-measured snack foods to eat. The television show will have eight commercials imbedded within it. Of the eight commercials, five commercials will represent the study condition (five advertising healthy food, five advertising unhealthy food, or five non-food related commercials). The three additional commercials will advertise neutral products (banks) and will remain the same in each condition. Snack foods being used in this investigation are red grapes and baby carrots for the perceived healthy snack foods; and chocolate chip cookies and potato chips for the perceived unhealthy snack foods. The television commercials representing the unhealthy category include commercials advertising M\&M's candies, Oreo cookies, Cheez-it crackers, 3 Musketeers chocolate bars, and Doritos chips. The television commercials representing the healthy category include commercials advertising Fiber One bars, Honey Bunches of Oats cereal, Nature's Path granola, Nestle fruit yogurt, and Musselman's apple sauce. The non-food related television commercials include commercials advertising All-State car insurance, Geico car insurance, State Farm car insurance, Travelers car insurance, and Liberty Mutual car insurance. The three neutral non-food related commercials that will remain the same in each condition are commercials advertising Fifth Third bank, Ally bank, and Capital One bank.

The specific aims and hypotheses are:

1. Women exposed to a television show with commercials imbedded advertising food will consume more food than women exposed to a television show with non-food related commercials.
2. Women will consume more food when exposed to a television show with commercials advertising "unhealthy" food as compared to a television show with commercials advertising "healthy" food.
3. Women will consume the most food when exposed to a television show with "unhealthy" food commercials and have "unhealthy" snack foods available to consume.
