A contributing factor to the rising prevalence of obesity may be increased portion sizes. However, the effect of portion size has not been studied independent of the effect of quantity of food in the context of a behavioral weight loss program. Providing pre-portioned single servings of food may make it easier to reduce caloric and dietary fat intake improving weight loss. In addition, breakfast skipping is associated with obesity and breakfast consumption is associated with weight loss success. Therefore, the objective of the proposed study is to investigate the effect of portion size on consumption of provided breakfast foods in the context of a behavioral weight loss program. Participants will be randomized to 1 of 2 standard 12-week behavioral obesity interventions. The first intervention, serving as a control, will provide participants with breakfast foods in non-portioned containers (Standard). A second intervention will provide participants with the same type and quantity of breakfast foods but they will be provided in pre-portioned single servings (Portion). Dependent variables include the number of calories consumed from the provided foods as well as overall caloric and fat consumption. If the provision of food in pre-portioned servings is effective at decreasing intake, future directions include conducting longer interventions to improve long-term weight loss outcomes in standard behavioral interventions.
