Brief Summary:
Specific Aims Environmental factors contributing to overconsumption such as larger food portion sizes may be contributing to the obesity epidemic The objective of the proposed study is to examine the independent and combined effects of portion size and quantity of food on intake in normal weight males and females Participants will be randomly assigned to one of four conditions varying in the portion size and quantity of junk food provided small quantity of food packaged in small portions SSP small quantity of food packaged in large portions SLP large quantity of food packaged in small portions LSP and large quantity of food packaged in large portions LLP A box containing four different junk foods packaged according to one of the four conditions will be given to participants to take home for three days The total amount of food consumed from the box over the three days will be measured It is anticipated that portion size and quantity of food both independently and combined will influence intake such that larger portion sizes and quantity of food provided to participants will produce greater intakeSubject Population We propose to recruit 60 healthy men and women aged 18-50 years with a body mass index BMI of less than or equal to 28 Participants will be non-smokers unrestrained eaters and have no known food allergies to the foods used in the investigationMethodsDesign Participants will be randomly assigned to one of four conditions varying in portion size small versus large and quantity of food provided small versus large A box containing four junk foods packaged according to one of the conditions will be provided to participants They will be encouraged to eat as much or as little of the food as they want but to at least taste each of the four foods over the three-day period During this time they will be instructed to not eat any other junk foods At the end of the three-day period participants will return the box with any remaining uneaten junk foodData Analyses The dependent variables the amount of grams and kcals consumed from the provided junk foods will be examined between the four different conditionsSignificance If portion size and quantity are related to intake subsequent studies will develop clinical interventions related to reducing portion size andor quantity of food available in the household
